Quick Answer

We build custom OpenCart extensions tailored to your specific requirements. From simple modules to complex integrations, we deliver clean, maintainable code.

Built Exactly to Your Specifications

When no existing extension meets your needs, custom development is the answer. We build bespoke OpenCart extensions that integrate seamlessly with your store and follow OpenCart coding standards for long-term maintainability.

What We Build

  • Custom Modules: Storefront features, admin tools, and dashboard widgets. Any feature you need that does not exist in the marketplace.
  • Payment Gateways: Integration with regional or specialized payment providers not currently supported by OpenCart.
  • Shipping Methods: Custom shipping calculators, carrier integrations, and delivery management tools.
  • Product Management: Custom product types, advanced option builders, bulk management tools, and import/export utilities.
  • Reporting and Analytics: Custom dashboards, advanced reports, and data visualization tools for the admin panel.
  • Third-Party Integrations: Connect OpenCart with any external service through custom API integrations packaged as extensions.
  • Automation Tools: Scheduled tasks, automated email campaigns, inventory management rules, and workflow automation.

Development Standards

  • Clean MVC architecture following OpenCart coding conventions.
  • OCMOD packaging for non-destructive installation and easy removal.
  • Proper SQL injection prevention and XSS protection.
  • Multi-language support using OpenCart's language system.
  • Multi-store compatible where applicable.
  • Admin interface that matches OpenCart's native UI patterns.
  • Complete documentation including installation, configuration, and usage guides.

Development Process

  1. Requirements Gathering: We document your functional requirements, user stories, and acceptance criteria.
  2. Technical Design: We design the database schema, API structure, and UI mockups for your review.
  3. Development: We build the extension with regular progress updates and milestone reviews.
  4. Testing: Comprehensive testing including unit tests, integration tests, and manual QA on multiple OpenCart versions.
  5. Delivery: We deliver the packaged extension with complete documentation and install it on your store.
  6. Support: 60 days of post-delivery support to address any issues and make minor adjustments.

Frequently Asked Questions

How long does custom extension development take?
Timeline depends on complexity. Simple modules take 1-2 weeks. Medium-complexity extensions with admin interfaces and API integration take 2-4 weeks. Complex extensions with third-party integrations and advanced logic may take 4-8 weeks.
Will the extension work with future OpenCart updates?
We build extensions using OCMOD and OpenCart coding standards to maximize compatibility with future updates. Minor OpenCart updates rarely break well-coded extensions. Major version updates may require modifications, which we can handle.
Can I sell the custom extension on the OpenCart marketplace?
That depends on the licensing agreement. By default, custom development is for your use only. If you want to resell the extension, we can discuss licensing terms. We also offer partnership arrangements for marketplace products.
Do you provide the source code?
Yes, you receive the complete, unencrypted source code for all custom extensions. We believe you should have full control over software you paid for. The code is well-commented for easy maintenance.
Can you maintain the extension after development?
Yes, we offer maintenance plans that include bug fixes, OpenCart compatibility updates, and minor feature enhancements. Plans are available on monthly or annual terms based on your expected needs.
