Frequently Asked Questions

Can you modify my existing OpenCart theme?
Yes, we regularly modify existing OpenCart themes. Whether you need color changes, layout adjustments, new page templates, or responsive improvements, we can customise your current theme without requiring a complete redesign.
Will customisations survive OpenCart updates?
We use OCMOD (OpenCart Modification system) for customisations whenever possible. OCMOD modifications are applied through XML-based file patching, which means they can be reapplied after OpenCart core updates. Direct file changes are documented for manual re-application.
How much does OpenCart customisation cost?
Costs depend on complexity. Minor theme adjustments start from $50-100. Feature development ranges from $200-2,000 depending on scope. We provide detailed quotes after reviewing your specific requirements.
Can you build a custom checkout flow?
Yes, custom checkout flows are one of our most common requests. We can implement one-page checkout, multi-step checkout, guest checkout modifications, custom field additions, and conditional logic based on product type or customer group.
Do you offer ongoing maintenance after customisation?
Yes, we offer maintenance plans that include monitoring, bug fixes, security patches, and minor updates. Plans are available monthly or annually depending on your needs.
