Frequently asked questions

Got questions about Magento development, migration, or maintenance? We’ve answered the most common ones below.

We support all major eCommerce platforms like Shopify, WooCommerce, Magento, BigCommerce, Laravel-based systems, custom headless frontends (React/Next.js), and Node.js backends. We also work with ERP systems and legacy CMS platforms via API middleware.

Apps are often one-size-fits-all with limited control, poor performance, and feature constraints. Our custom integrations offer faster sync, better data accuracy, support for custom business logic (like bundled products or tiered pricing), and are scalable for enterprise needs.

Yes. Our integration brings all your marketplace orders, stock updates, and product edits into a single interface or into your existing ERP — with logs, sync history, and smart alerting. We can also integrate analytics and fulfillment systems into the same backend.
Absolutely. We offer 30 days of post-launch support for fixes, then optional monthly retainers that include scaling to new platforms, feature enhancements, and ongoing system maintenance. Your tech evolves with your business.

Marketplace APIs (especially Amazon and Walmart) often update their schema or protocols. We continuously monitor API status, handle change logs, and roll out version updates so your integration stays stable and compliant.
