Insights from our experts
FAQs
How long do you typically develop eCommerce solutions?
The timeline for our eCommerce software development services depends on the project’s complexity, integrations, and design requirements. A basic custom eCommerce software development project may take 3–4 months, while large-scale eCommerce website development services with advanced features, ERP/CRM integration, and mobile apps can take 6–9 months. We use an agile approach to deliver usable features early so you can start seeing results before full launch.
How does Onix ensure eCommerce performance & security?
As an experienced eCommerce software development company, Onix follows strict performance optimization and security protocols. We design scalable architecture, implement caching strategies, and ensure fast load times across devices. For security, we use SSL/TLS encryption, role-based access control, secure API integrations, and follow PCI DSS compliance for payment processing, ensuring your eCommerce software solutions remain safe and reliable.
Is custom eCommerce development undoubtedly better than off-the-shelf platforms?
While off-the-shelf platforms like Shopify or WooCommerce are quick to launch, they often limit scalability, customization, and integration flexibility. With custom eCommerce software development, you get a platform tailored to your business model, customer journey, and growth plans. This means no vendor lock-in, seamless third-party integrations, and the ability to scale without costly workarounds. Our eCommerce development solutions are built for long-term ROI and adaptability.
What tools are essential for a successful eCommerce launch?
A successful launch combines the right eCommerce web development services with strategic integrations. Essential tools include a robust CMS or eCommerce platform (Magento, Shopify, BigCommerce), secure payment gateways, inventory and order management systems, CRM integration, analytics tools, and marketing automation. Our eCommerce software solution development process ensures all these tools work together for maximum efficiency and conversion.
