Grocery Mobile App Development in 4 Steps — Tips from Onix

As smartphone adoption and cashless and contactless payments are growing worldwide, and consumers are more demanding than ever, building an on-demand grocery delivery app or another solution catering to their needs can become a game-changer for your business. 

 

For example, a Ukrainian company’s decision to create a members grocery app resulted in their sales increasing by UAH 1 billion in a year! 

The Fayno Market grocery app is an example of Onix’s grocery mobile app development.

 

Intuitive mobile applications like this facilitate seamless customer experiences, increase business efficiency, create new jobs, help businesses reach new audiences, and facilitate highly accurate targeting, boosting sales and revenue. British supermarkets that invested in online ordering software reportedly also saw increased brand recognition!

 

Big supermarket chains, small stores, tech startups — all can benefit from grocery app development. This article unpacks the process in lay terms and gives an idea of the approximate cost.

 

High Time to Build Grocery Apps

The global online grocery market is estimated at USD $73.45 billion in 2025 and is projected to grow at a compound annual growth rate (CAGR) of 26.83% from 2025 to 2034.

In 2024, Asia Pacific accounted for 60% of the market. The region’s online grocery market surpassed $44 billion in 2025 and is accelerating at a CAGR of 26.93%.

 

For example, 85% of Vietnam’s urban digital users had already used online grocery services in 2022. Due to digitalization, India and China are also markets with high potential.

North America is another promising market for on-demand grocery app development. In the US, 86% of millennials and 83% of Gen Z consumers were shopping for groceries online in 2023. 39% of consumers reportedly prefer buying groceries through a mobile app.

As of February 2025, over 80 million households were ordering groceries online. eGrocery sales reached $10.3 billion that month, 31% higher than in February 2024. The market is driven primarily by the aggressive promotion of membership or subscription offers.

Delivery services remain the fastest-growing segment, accounting for 44% of total eGrocery sales in the US. In February 2025, online delivery sales reached $4.5 billion, which is 45% more than in the same month of 2024. Ship-to-home saw a 29% increase, reaching $1.8 billion in sales.
   
According to a report that studied the grocery retail sector in several European countries, online grocery shopping sales there may double by 2030.

The surveyed consumers stressed that they expect quick, easy shopping and flexible fulfillment options. They indicated eco-friendly shopping and personalized offerings as desirable options and even mentioned advanced virtual reality offerings.

In the UK, 59% of consumers did some grocery shopping online in 2023, and 17% used rapid home delivery.

Consumers worldwide continue shifting toward buying through mobile apps. They appreciate the ability to order groceries anytime and anywhere, track delivery, and use convenient mobile payment options, saved shopping lists, or personalized product recommendations.

The Fayno Market grocery app features personalized special offers integrated by Onix.

 

It’s also possible to create a grocery delivery app integrated with artificial intelligence (AI). It will reveal shopping patterns and suggest relevant products, improving shopping experiences and sales.

A survey of 1,000 American consumers revealed that 53% of consumers are more likely to shop with a retailer that has a mobile app than one without.

Mobile grocery shopping will likely grow even further as smartphone proliferation continues, especially in emerging markets.

 

Use Cases for Grocery Mobile App Development

The most common grocery shopping app business models include the following:

 

1. Apps for small grocery chains and independent stores

Small local chains and stores’ primary motives behind mobile app development are customer retention and enhanced in-store experience. For instance, the same survey revealed that 73% of consumers were using mobile apps to verify in-stock items before visiting a store.

 

If they build an online grocery delivery app, it can significantly enhance their appeal and reputation and provide part-time employment for local youth.

 

For example, for Fayno Market positioning itself as “grocery stores next door” Onix built a mobile app that supports the company in: 

 

• going green
• digitizing and streamlining processes
• supporting local producers
• meeting social responsibility commitments
• engaging more customers in the loyalty program
• adaptation to the changing market using consumer activity analysis
• gaining a competitive advantage in marketing

 

Onix delivered one solution for customers and another for the grocery store employees. The consumers’ app enables them to:

 

• view discounts on specific products in the home or other Fayno Market groceries
• view personalized offers — discounts formed for an individual patron based on their purchase history, personal information, and responses to various surveys 
• track their progress through 5-level loyalty programs
• use their loyalty card while shopping
• view their purchase history and analyze their spending
• learn about charitable programs and news
• acquire, track, and donate bonuses towards charitable causes
• purchase and send gift cards

In the app for employees, users can:

 

• access the same functionalities as consumers, i.e., loyalty programs, bonuses, gift cards, scanning their barcode at the checkout point, etc.
• view special offers for employees
• view their work schedule
• send and receive push notifications, e.g., to call a selected employee or employees to a specific workstation

Small grocery app features typically enable customers to:

 

• check the price and availability of an item in the nearby shop, product listings, current discounts, and possibly additional information
• view coupons, deals, and weekly circulars online
• make shopping lists
• receive notifications, e.g., weekly promotions, when their favorite products are available in the nearest store, etc.
• join a loyalty program, track bonus points, and pay with accumulated bonuses
• order home delivery

 

2. Supermarket chain apps

Besides the above functions, a supermarket mobile app can offer virtually anything to attract new audiences, increase customer engagement, and stand out among the competitors.

 

Walmart’s mobile app is an excellent example of grocery ordering app development by large chains. In three years after launching it, Walmart observed that app users were shopping with Walmart twice as often and spending 40% more than customers who didn’t use the app.

Currently, the app enables users to:

 

• order and collect their order curbside or have it delivered by FedEx or UPS within two days or as little as one hour
• reorder frequently purchased items
• subscribe to thousands of everyday essential products at regular prices which will be automatically delivered on their preferred cadence
• refill and manage family prescriptions
• scan items’ barcodes to check prices and build lists
• stay on budget while shopping (when they select an item, the total order cost is shown with tax)
• check out contact-free
• see how furniture and other items will look in their home, and more.

METRO UA is an example of supermarket app development by Onix. The mobile app was designed to make shopping more convenient and digitize some offline customer processes at the Ukrainian branch of METRO C&C, an international wholesale grocery retailer.  

The app’s functionalities currently include:

 

• Electronic METRO customer card that substitutes the physical card at check-out.
• Barcode scanner for checking a product’s current price. The app conveniently keeps all scanned items in a carousel and updates the prices every time the user opens the app.
• Electronic promotional brochures relevant to a specific store.
• Creating shareable shopping lists manually, via scanning, and from an online catalog. The app automatically groups the items by categories corresponding to the physical store’s departments to help shoppers move through a huge store purposefully.
• Map of all METRO stores and their hours of work. 
• METRO loyalty program, where users can choose the type of reward (bonuses or discounts), accrue bonuses upon each purchase, generate vouchers during subsequent purchases, and level up their membership.

 

3. Aggregator/intermediary grocery mobile apps

These apps act as a middle-man between multiple stores and online shoppers. Users can order groceries from a store without downloading its app. Grocery marketplaces may rely on a supermarket’s delivery service or have their own pool of drivers.

An aggregator grocery app thus may feature:

 

• advanced search and filters
• unified product listings so users can order from different supermarkets
• search results from all stores in the neighborhood
• recommendation engine suggesting products similar to search results, based on previous purchases, or what other users order
• ability to track the order on the map and receive push notifications
• ability to leave reviews about purchased products and rate the store
• live chat with courier during shopping
• multiple payment options, including mobile payments, cash, credit card, or QR code payment

Intermediaries that create grocery apps typically earn money by charging a fee for each order either to the merchant or the consumer (commission on the order or delivery service fee). They can generate additional revenue through partner supermarkets and third-party ads.

Those looking to create grocery delivery apps may draw inspiration from Instacart with an estimated 13.7 million customers. Some 600K shoppers pick up products at 80K retail locations across the US and deliver orders to customers. 

 

Instacart allows users to:

 

• view nutritional information and filter groceries according to their dietary requirements
• find exclusive deals and coupons
• use Group Carts to shop together with friends, family, and neighbors
• chat with the shopper and select replacements when needed

BigBasket is an example of successful grocery delivery app development in India. The on-demand food delivery giant serves 10 million customers in 300+ cities and towns with the help of 35K delivery partners.The app conveniently serves its clientele in seven regional languages and facilitates search via barcode scans and voice commands.

 

Customers can choose from 20K+ products, including fresh produce, rice, dals, meats, spices, seasonings, beverages, household essentials, pet and personal care products, and have their orders delivered in 15-30 minutes. BigBasket offers fast and secure payments by UPI, net-banking, credit and debit cards, and e-wallets.

4. Courier apps

These apps enable users to hire a personal shopper who will buy the ordered groceries from a store or food market and promptly deliver them. If an app has a contract with a particular store or chain, it would charge a commission on every order. Otherwise, it charges a service fee to the customers.

Another interface enables the delivery staff to receive, view, and manage orders, turn their availability on and off, etc.

HappyFresh is Indonesia’s leading online grocery delivery service. Millions of users shop from 600+ online supermarkets, specialty stores, and fresh marts. An AI-powered personalization engine helps customers save time by suggesting products they buy often, and discounts, deals, exclusive daily vouchers, promotions, and loyalty points help save money.

HappyFresh has a quality control team to ensure a high standard of the goods, trained shoppers, and riders to deliver the orders to customers within an hour.

Now, let’s see how to build a grocery app for your business.

 

How to Make a Grocery App in 4 Steps

Grocery mobile app development can be divided into the following stages:

 

1. Research and project planning.

Firstly, you need to identify the customers’ pain point and your business problems to solve through the mobile app. Then, you should come up with a better solution than your competitors offer. 

 

Research your target audience, demand, trends, competitors’ mobile apps, business models, and possible marketing strategies. It’s reasonable to start by investigating the best practices established by national and global industry leaders. Then, identify competitors in your niche, analyze their advantages and shortcomings, and try to figure out what improvements might beat them.

It would be best to end this stage by documenting the project requirements and creating basic wireframes. These will facilitate budget planning and communication with software developers.
  

If you don’t have the time or confidence for these tasks, you can delegate them to an agency like Onixs. Experts can help prioritize the desired app features, suggest solutions, recommend technologies, verify your idea viability early on, estimate the project cost, identify possible risks, and organize timely software development.

Experts often recommend starting with a minimum viable product (MVP) to save time and budget and reduce risks. An MVP includes only the essential grocery app features. After the MVP is launched, obtains a user base, and collects feedback from the first users and investors, the company can gradually add more advanced features.

Certain functionalities are likely to be found in any mobile grocery app:

 

• Registration with as few text fields as possible
• Log in with a password and email address, phone number, or social media profile
• Personal profile with information about a user, including their name, phone number, email, address, favorite grocery store, etc., with general account management options and app settings
• Marketing information on sales, discounts, promotions, coupons, etc. 
• A quick and easy search that can be facilitated by product categories and filters, predictive search, and favorites lists
• Product listings, including at least the product name, pictures, and price, and possibly comprehensive nutrition and allergens information, rating, reviews, details for vegans, religious groups, etc.
• Digital loyalty card with a barcode or QR code and features related to bonuses, rewards, redeeming points, etc.
• Shopping list
• Push notifications, including order status updates, location-based information about offers, current sales or promotions at nearest stores, discounts on items they buy often, availability of favorite goods, abandoned shopping cart reminders, company news, etc.

However, different use cases require different feature sets. For example, if you have a pick-up option, you might add the customer’s location tracking and QR-code system to identify customers at pick-up points. Grocery delivery mobile app development implies integrating multiple payment options and an interface for drivers and couriers.

 

Additionally, you may add to the MVP or subsequent versions of your mobile app:

 

• prices comparison
• voice search
• chatbot that can answer generic questions on products, delivery statuses, etc.

 

… or any features, valuable for your business and your customers, that can make your app more useful, competitive, and unique.

For instance, your app may recommend recipes based on the food items bought previously or form a user’s shopping cart based on a particular recipe. 

Onix’s AI Chef, an AI-powered nutritional app, recommends dishes based on user’s preferences and feedback. 

Along with a mobile grocery app, you will also need an admin panel for managing all in-app processes. These functions are usually realized through a web application. 

For example, a grocery delivery service managers and administrators may need an interface and features for:
 

• order management and tracking
• tracking payments 
• real-time inventory management
• in-app content management
• running promotions, offers, rewards, etc.
• creating, sending, and automating push notifications
• keeping track of courier working hours
• managing consumers and other app users
• providing support for consumers and stores and handling returns and refunds
• keeping track of various statistics, such as monthly, weekly, and daily users, most and least popular products, in-store purchases/pick-up/home delivery numbers, days with more and fewer sales, most popular payment methods and price range for customers, most and least used app features, etc.

2. Assembling a grocery app development team.

Online grocery app development can be carried out by in-house IT experts, freelancers, or an external dedicated team. Alternatively, you can outsource the job to an offshore software developer like Onix for greater savings.

Your minimal app development team is likely to include: 

 

• Project manager
• Mobile app designer
• Android developer and/or iOS developer
• Back-end developer
• Web developer 
• 2-3 quality assurance (QA) specialists

When recruiting grocery app developers, look for specialists in the following technologies:

For the app’s back-end development:

Programming languages: JavaScript, Python, or PHP

Frameworks:

- JavaScript: Angular, Ember.js, Meteor, React, Vue.js
- Node.js: Express.js, Nest.js
- PHP: CakePHP, Laravel, Symfony
- Python: Django, Flask

Database: MongoDB, MySQL, PostgreSQL

Caching tool: Redis or Memcached
 
Server: Amazon Web Services, DigitalOcean Cloud Services, Linode, Microsoft Azure, Vultr 

Web server software: Apache HTTP Server, Nginx

For the mobile app development:

Native mobile apps: Kotlin (Android), Swift (iOS)
Cross-platform mobile app: Flutter, React.js + React Native
 
Global payment s: Braintree, Stripe, PayPal

For the web admin panel development:

Programming languages: CSS, HTML, JavaScript, TypeScript

 

3. Grocery app design.

The primary goal of grocery mobile app design is convenience. A practical, intuitive, and visually appealing solution will nurture customer loyalty and garner positive reviews and recommendations.

Quality grocery app design implies:

 

• a smart user experience (UX) design that will make the purchase journey as short and smooth as possible
• minimalistic and clean user interfaces (UI) for customers, couriers, and other users
• brand design that vividly delivers the company’s message and distinguishes the app from the competitors

  

The Fayno Market app is an example of grocery mobile app design by Onix.

Here are several UX tips from Onix’s experience, including our work for Fayno Market and METRO UA:

 

• Minimize the users’ need to search for anything. Discounted products should be the first thing shoppers see on the home screen. It should list the most popular products first.
• Department categories and subcategories can be neatly placed in a drop-down menu.
• Customers must be able to save and easily return to their cart-in-progress. Consider including a progress indicator for users to know where they are in the check-out process and create a solid and clear call-to-action.

The eCommerce UX/UI design best practices also apply to online grocery marketplaces.

 

 

4. Mobile and web apps development and testing.

Every project starts with fixing a technical base for further operations. Then, the web and mobile developers implement the designed interfaces. At the same time, the back-end developers build databases and implement application programming interfaces (APIs), various services, and libraries for the system’s inner workings.

The app has to be coded to meet all applicable requirements and go through
 

• functional testing
• usability testing
• interface testing
• performance testing
• security testing

It is essential to check whether the mobile app runs equally well on different devices, debug the entire code, and remove all issues before deployment. However, error elimination and maintenance will continue long after the app is released to Apple’s App Store or Google Play. 

 

How Much Does Grocery App Development Cost?

The main factors that determine grocery app development cost are:

 

• the app complexity and the number of features
• for which platforms it is being developed
• the choice of technologies and third-party services, such as payment gateways
• the app developers’ salaries or hourly rates, which differ from country to country and from company to company

 

For example, the first factor directly impacts the number of man/hours necessary for grocery shopping app development:

 

 

You can roughly calculate the cost by multiplying the development time by the specialists’ hourly rate. By outsourcing the development to countries with a lower cost of living, such as Eastern Europe or the Indian subcontinent, you can negotiate lower rates and save up to half of your budget.

 

For example, with Onix’s average rate of $37/hour, the above project time estimate translates into $46K-$53K.  

 

Onix’s Experience in Grocery Store App Development

For METRO C&C, an international wholesale grocery retail company, Onix developed branded mobile apps for the iOS and Android platforms.

The project supports METRO’s long-term strategy to:

 

• digitize the current offline customer processes
• facilitate shopping at physical METRO stores
• pave the way for future online sales

 

Onix’s team joined the project after the specification and design for the minimum viable product were developed. They started with an audit of the UI/UX design, made some recommendations, and had the app design adjusted.

 

The MVP’s functionalities — registration, customer card, METRO stores list, and advertising brochures — were developed in close cooperation with the client.

 

The loyalty program launch was a milestone in the development of METRO UA wholesale shopping apps. Eventually, Onix’s developers implemented the product barcode scanner, shopping list, linking stores, push notifications, vouchers, and the product catalog.

 

The supermarket applications have had 650K+ downloads already and serve 130K active users monthly. 24% use the iOS app and 76% the Android app. Onix’s team will soon be adding new functionality to the apps.

 

For Fayno Market, Onix built from scratch a solution that included:

 

• a native iOS application
• an Android app
• a database for the marketing department

The latter enables marketers, for example, to personalize special offers based on the analysis of the most frequently viewed products, popular purchases, and other customer activity data.

It took significant effort to generate tailored offers considering numerous parameters and build a DB management system that would speed up the request-response flow.

Onix’s experts chose PHP-based back-end development and other technologies that promote functionality customization, massive database integration, and content management.

The Fayno Market team didn’t want to use an admin panel, so we built a tool allowing them to administrate the database. The integration with their custom enterprise resource planning and customer relationship management (CRM) systems was challenging, but we worked out an architecture that perfectly met the client’s needs.

 

In the first year of its operation, the mobile app helped Fayno Market to raise

 

• the number of receipts by 6.6 million
• accrued bonuses by 7 million and withdrawn bonuses by 7.3 million
• the sales by 1 billion UAH

Eventually, our team integrated the Fayno Market app with the Creatio CRM and ITTel telephony. It is also connected with Fayno Market’s inventory management system to synchronize data within the chain’s ecosystem. RabbitMQ, an event management system, facilitates the data flow between them.

In 2023, Fayno Market ordered an app upgrade. The chain expanded, updated its brand identity and loyalty program, and developed new trademarks and brands.

 

The company’s growth also increased the load on the system. For example, currently, the app processes nearly 6 million user requests and 15 million events from Fayno Market’s CRM and inventory systems daily.

 

Onix’s team had been optimizing the system to adapt it to the growing loads until optimization was no longer feasible. When Fayno Market updated its internal architecture, it became clear that software required the same to enable further optimization.

 

Using a new brand style guide, Onix’s designer completely reformatted the mobile app, updated the logic, and added screens for new features, such as incentivized surveys, spending analytics, and bonus management. He also overhauled the user profile and promotions and offers.

Onix’s team developed a fresh design for Fayno Market’s mobile app.

 

Writing the app architecture from scratch took 23 days. The expert again used PHP, but now on a new runtime — Laravel Hyperf with Swoole engine.

 

This helped improve the mobile app performance tenfold while retaining the same server. After 18 months since the overhaul, the load on the server was still only 30%.

 

We also ditched the old clunky batch system and built a real-time pipeline. Previously, purchases were landing in an external storage and were pulled into the central system every 30 minutes. That delay disrupted the user experience and the support team’s work: they couldn’t see new purchases until the next batch came in.

 

Project manager Volodymyr Hordiienko explained: “Now, transactions hit the system through a dedicated channel, we validate them on the fly, update accounts, and grant access to the content in real time. The customer’s session remains active, and they promptly get the confirmation on the mobile device. The lag gone also means instant visibility for the support. Real-time sales data helps make smart, timely decisions. No more waiting, no more blind spots”. 

 

As of March 2025, the mobile apps had seen 659K registrations and were serving 130K unique monthly users.

 

One of the latest integrations, with the Diia e-governance portal, enables Fayno Market employees to file electronically signed vacation requests and other corporate documents using the mobile app.

 

The integration with Diia was one of the most challenging tasks. First, Fayno Market contacted the state service, informing them that the company would like to tap into Diia’s electronic document management capabilities. After accepting the request, Diia’s team created a chatroom to communicate with Onix’s developers and gave us access to the project documentation.

 

Some issues arose from the imperfect documentation (the ongoing project is relatively new), but Diia’s team was always quick to respond and eager to help.

 

Diia eSignature uses external signatures. Users do not actually send files to sign; instead, Base64 hashes are generated and sent to Diia in lieu of the files. 

 

Diia employs specific state-approved functions for passive encryption operations that are unavailable in some programming languages. Onix’s experts found a C library that was developed at the Igor Sikorsky Kyiv Polytechnic Institute. Diia’s team helped us contact the creator, who converted it into a PHP library so we could use it.

 

This library is pretty big and complex, so it took Onix’s developers some time to figure out the details and connect it for successful feature implementation.   

 

The mobile app will soon facilitate online recruitment, another step towards electronic document management and saving the HR team time. A job applicant will fill out an online form, attach the required documents, file the application, and, if accepted, receive an interview invitation in the app.

 

Each Ukrainian has a Diia account, which stores their essential documents, such as passports and driving licenses. We created an ‘app within an app’ to enable Fayno Market’s customers and employees to access those documents through the mobile app.

 

When the code written by Onix requests a user’s data from Diia, a deep link is generated and sent to the user. The Fayno Market app redirects the user through the deep link to Diia, which identifies the requested document by a special ID.

 

The system displays to the user a list of documents and who requests access (in this case, Fayno Market’s verified account), and either accepts or declines the request. Once access has been granted, the app’s back-end, through a webhook, receives the requested documents with an electronic signature.

 

One of the trickiest tasks was sending Fayno Market PDF files with an electronic signature set in. Normally, PDF files are stored on a server, while electronic signatures are stored in the cloud.

 

It took some communication with the developers of Diia’s encryption libraries to learn how to retrieve an eSignature from Diia and apply it to a locally stored PDF file so that Fayno Market could also apply its own electronic seals to it. The management of multiple validations was pretty challenging.

 

So was the feature testing. Onix’s side would apply eSignatures to PDF documents, and Fayno Market’s team would read those, validate the signature through Diia, and then apply their own eSignatures. Then, Onix’s side had to retrieve the signed documents and display them to the mobile app user. This testing flow required full involvement from both teams simultaneously.

 

Personal data can’t be compromised during this process because Fayno Market’s app does not store them. It only receives a PDF file’s binary data passing through the queueing system. So, if anyone manages to access the server through the app, they won’t find any documents there.

 

The electronic document management functionality, which comprised an employee’s list of documents, dynamic online forms, integration with Diia Sharing and Diia eSignature, and required significant amounts of communication with Fayno Market’s IT team, took about 3 months to implement.   

 

Another feature under development supports the ‘Fine Space’ concept: opportunities for store visitors to buy coffee, juice, donuts, and other snacks without standing in queues. The app will be connected with in-store smart machines through NFC chips and with MonoBanks’ contactless payment system. The ‘Fine Space’ flow will involve NFC tags and QR codes.

 

Simultaneously, Onix’s designer developed the screens for Fayno Market’s auto-checkouts to make the shopping process even more convenient, personalized, and sustainable.

 

In 2024, Onix also took over the work on the Fayno Market website from another developer: it had been tricky to manage the interconnected website and mobile apps with two remote teams. 

After Onix’s designer created a new website interface following the new brand style guide, Fayno Market decided to give it a fresh start.

 

The project team included a web UI/UX designer, full-stack developer, team lead, QA engineer, and PM. (No DevOps was involved: the same full-stack developer deployed the website.)

 

Together, this dedicated team made a new website from scratch in 4 months and integrated it to some extent with the mobile app.

 

The new Fayno Market website has two components:

 

1. the customer-facing website
2. the admin panel for Fayno Market’s managers, marketers, and others

 

The full-stack solution has front-end, back-end, database, and business logic realized through a monolithic system.

 

The admin dashboard provides access to:

 

• The Fayno Market team list
• Reports and analytics
• Job applications Fayno Market posts and receives
• Partner applications
• Cooperation ideas
• Partner stores
• Production requests
• Questions and answers on the website
• Rules and policies

 

The new website features job listings and job application and partnership request forms.

 

The admin panel’s job listings tab enables prioritizing jobs, turning the visibility on/off, and indicating requirements and restrictions.

 

There are integration tools (API) on Onix’s side that Fayno Market’s IT team uses to retrieve job applications from the website and put them into Fayno Market’s HR pipeline. The applicants’ statuses from the pipeline are retrieved through the same API and displayed on the admin dashboard.
 

Once Fayno Market employs a consumer, it changes their status in the system and upgrades their mobile app to the Employee interface.

 

A similar solution, including an API, was developed for businesses wishing to partner with Fayno Market or to become suppliers. They can fill out a form on the website, which the company’s supply chain managers will retrieve through an API developed by Onix. After processing the requests, the same API will return the requests’ statuses. 

 

Onix developed a custom content management system (CMS) that enables Fayno Market to manage the website’s News section and other content and easily create internal documents, such as vacation requests, financial aid, and other forms.

 

In the system, the managers create a document type, fields to fill out, and list the documents to attach. Then, they publish the new form that will appear in the employees’ mobile app. Employees can fill out the form, attach required documents retrieved from Diia, sign the form using an electronic signature, file the request, and receive it with Fayno Market’s seal. 

 

The new Fayno Market website is a custom solution. The admin/CMS features are on par with WordPress, but more straightforward. For example, Onix’s solution enables marketers to edit news and other website content more easily than the old, congested version. They can both edit texts and upload images and PDF files.

 

The website full-stack solution is written in Laravel using the Livewire framework. For the admin dashboard, Laravel Filament was used.

 

Full-stack solutions written in Laravel are axiomatically faster to implement. It’s much faster than dividing the back-end into APIs and creating an SPA, e.g., with Vue.js. It can also be done by one programmer, eliminating the issues of cooperation between front-end developers and back-end devs.

 

The full-stack development also means that the website’s SEO requires no extra effort, unlike apps that use Vue.js with its dynamic page rendering.  

 

Currently, the website is solely in Ukrainian. However, the Localization feature will enable Fayno Market to easily adapt it to English or another language, if needed.

 

Although the website and the mobile app have separate databases, there is some integration through an API. Namely, it enables the website to retrieve data from the mobile app’s database. The stores, discounts, and special offers displayed on the Fayno Market website are retrieved from the mobile app.

 

We did not merge the databases because the website is a more public-facing system with an open-source code. It was essential to prevent unauthorized access to more sensitive information through the website. The APIs facilitating data sharing between the mobile app and the website allow only the transfer of non-sensitive information.
 

The new Fayno Market website took approximately 1,500 man/hours to build. With Onix’s current hourly rate of $37, a similar project might cost around $55,000.

 

Here are some beneficial results of the grocery website development by Onix:

 

• The new website operates much faster than the previous site did. 
• The new website’s architecture is also up to date with current standards. Maintenance and new feature implementation will also be faster now, saving FM significant time and money.
• The new custom CMS has received positive feedback: Fayno Market’s employees praise the system’s usability and the website’s visuals.
• Employees using the website daily say it is way more convenient now. The marketers especially enjoy the new admin panel and are looking forward to new features being added to it. 
• The basic job listings & applications management system simplified the recruitment process for Fayno Market’s HR.
• Custom CMS development also makes accommodating the client’s emerging needs easy.

 

Previously, the mobile app was a ‘black box’ for the team that managed Fayno Market’s website. The integration with the mobile app now provides insights into the mobile activities, such as charitable donations, coupons, and other stats.

 

Having integrated a mobile payment system and accumulated massive data on products, sales, etc., Onix’s team may obtain access to the inventory data and begin implementing shopping list and delivery functionality once the Fayno Market leadership approves the move.

 

One possible future project is a progressive web application that would replicate the essential features of Fayno Market’s mobile app. It would solve the issue of iOS and Android upgrades leading to hundreds of consumers with older phones losing access to the native mobile apps.

 

To Recap

As more and more grocery shopping occurs online, grocery app development becomes a vital move for businesses and an appealing option for tech companies. 

 

Grocery businesses need to strengthen the customer experience to protect their base business and improve the online channel profitability. To this end, they are recommended to:

 

• Use the knowledge of their customers and the value provided to them to deliver a more personalized, consistent, and smooth brand experience;
  Improve margins by offering lower-cost pick-up services, partnering with multiple third-party delivery services, and leveraging first-party retail media to offset the cost of serving online customers.

 

• A custom mobile app can improve customer experience, increase sales, and provide timely and accurate customer insights.

 

Are you ready to make your own grocery delivery app or another solution for grocery eCommerce? Do you need to enrich your customer experience with novel features or updated interface design? If yes, Onix is at your service!
