Illustrative project scope. The final configuration is agreed for your store.
What this service covers
01
Providers & methods
Review countries, currencies and preferred methods against provider and extension requirements.
02
Checkout integration
Configure the payment flow and review how it works with your theme and checkout.
03
Order status & testing
Check success, cancellation and failure using the provider’s test environment where available.
01
Choose methods your business can actually offer
We review the provider, merchant account, countries and currencies before selecting an OpenCart extension or custom connection. Provider approval, transaction fees and commercial terms remain with the payment provider.
Availability of cards, wallets and local methods for your account.
Compatibility with your OpenCart version, Journal and checkout extension.
Licensing, credentials and test-environment access.
02
Follow the payment from checkout to order status
The return page and the provider callback can arrive at different times. We define how the store recognises a confirmed, cancelled or failed payment and when order processing should continue.
Map provider events to the intended OpenCart statuses.
Review duplicate callbacks, interrupted redirects and pending payments.
Keep sensitive card handling within the selected provider integration.
03
Test success and the cases that need attention
We agree tests using the provider sandbox where available. The scope should include a successful payment, a cancellation and a failure, together with the order state and customer messages they produce.
Check mobile payment selection and return journeys.
Verify callback handling and the agreed operational follow-up.
Plan refunds or recurring-payment workflows separately if required.

Can you add Stripe, PayPal, Klarna or local methods?+
We can review these and other providers. Availability depends on your merchant account, region, currency and compatible integration.
Do I need a payment provider account before integration?+
A merchant account and provider configuration are normally needed. We review available methods, countries and currencies with your chosen provider. Account approval and commercial terms are handled with the provider.
Why can a payment succeed while an OpenCart order has the wrong status?+
The store and provider exchange confirmation messages. Missing callbacks, extension conflicts or status configuration can interrupt that flow. We investigate the integration and test the agreed success, cancellation and failure scenarios.
How are the cost and scope agreed?+
We review your current store and requirements before quoting. Investigation, implementation, licences and ongoing support are distinguished so you can see what the proposal includes.
How is the work tested before release?+
We agree representative pages, data and customer journeys for the scope. A test environment is used where appropriate, with publication timing and backup responsibilities discussed beforehand.
