OpenCart development services for merchants who outgrow plugins
OpenCart extension development fails when modules fight each other, upgrades break custom code, and marketplace channels drift from your golden source of truth. eRevolutions India builds OpenCart development programs for international brands that need maintainable commerce logic—not a patchwork of one-off fixes.
From our base in New Delhi, we partner with operators in the United States, United Kingdom, Canada, Australia, and the European Union who run serious catalog and order volume. Since 2012, our focus has been production systems: checkout, promotions, integrations, and automation-friendly data flows finance can audit.
OpenCart capabilities we deliver
- Custom extensions and integrations with disciplined upgrade paths.
- Marketplace and multi-channel sync architectures paired with operational monitoring.
- Performance and reliability work for catalog-heavy stores and API-driven storefronts.
- Collaboration with your mobile roadmap when you also need eCommerce mobile app development.
When to involve automation and mobile
Many high-ticket engagements combine storefront work with business process automation (orders, payouts, reconciliation) and marketplace integration solutions when the real pain is cross-system consistency—not only the admin UI.

Frequently asked questions
- Do you work on OpenCart 4.x and legacy 3.x stores?
- Yes. We prioritize OpenCart 4.x for new extension work and major integrations, but we support pragmatic migration and hardening paths from 3.x when that matches your roadmap and risk profile.
- Can you build marketplace integration (Amazon, eBay, etc.)?
- We design marketplace integration solutions with queued sync, mapping, and operational visibility—so listings, inventory, and orders stay aligned under real traffic. See also our dedicated marketplace integration page for scope patterns.
- How do you price OpenCart extension development?
- We scope extensions and integrations to acceptance criteria—often as a fixed program with milestones rather than open-ended hourly work. Discovery clarifies catalog complexity, channel count, and compliance needs.
- Do you offer hosting aligned with OpenCart workloads?
- Yes. Our capacity tiers express RAM, vCPU, and storage with upgrade paths through the client portal—useful when the same team owns software and production accountability.
