Payment & Fintech Integration

Getting money into a business is where most systems in Ghana break. A checkout that only takes one card, a mobile money flow that drops half its callbacks, a reconciliation spreadsheet somebody maintains by hand at the end of every day. None of that is a payments problem in the abstract, it is an integration problem, and it is the work this line does.

We integrate the rails a business actually needs, card, mobile money across the networks, and bank transfer, against the gateway that suits its volume and its settlement terms. The parts that matter are the ones nobody demos: idempotent charge handling so a retried request does not bill twice, webhook verification so a forged callback cannot mark an order paid, and a reconciliation view that ties every transaction back to a gateway reference.

The engineering standard behind this comes from systems where a failure costs real money. Our founder built payment integrations and a national USSD channel as a senior software engineer at previous companies, carrying over GHS 100M in transaction value. That is where the bar for this work was set.

What you get

  • Checkout that takes card, mobile money and bank transfer without a separate flow for each
  • Webhook handling that verifies signatures and survives duplicate and out-of-order delivery
  • A reconciliation view that matches every payment to its gateway reference
  • Test-mode credentials and a sandbox run before a single live cedi moves

Common questions

A single gateway against an existing system is usually two to three weeks, most of it spent on the parts you cannot see: webhook handling, retries, and reconciliation. Multiple rails, or a system that has no clean place to put a payment record, takes longer. We give you a range after looking at the code, not before.
