eCommerce App FAQs
1. Can you sync the mobile app with our existing Shopify or WooCommerce store?
Yes, absolutely. We build real-time synchronization connectors using Shopify Admin APIs or WooCommerce REST APIs. When you update a product catalog, change a price, or receive orders on your web store, it automatically syncs with your mobile clients.
2. What is the typical cost of eCommerce app development in India?
A standard mobile app syncing with an existing WooCommerce/Shopify store starts around $3,000. Complex eCommerce platforms (multi-vendor marketplaces, bespoke database architectures) range from $10,000 to $35,000+.
3. Which framework is best for eCommerce apps?
For 90% of stores, we recommend Flutter. It allows building iOS and Android apps from one codebase, reducing cost and maintenance by 40%, while providing a fast, native-grade checkout experience.
4. How do you handle mobile checkout security?
We use secure checkout flows that integrate Stripe, PayPal, and Apple/Google Pay SDKs directly. Payment data never touches your app servers, ensuring full compliance with PCI-DSS security standards.
5. Do you sign an NDA before we start scoping?
Yes. We sign a Non-Disclosure Agreement (NDA) before any detailed scoping or wireframing takes place. Your product data and app ideas are protected from day one.
6. What support do you offer after launching on the app stores?
We provide a free 30-day bug-fix warranty to ensure your launch is stable. After that, we offer monthly support retainers for security monitoring, payment API updates, and adding new features.
