Payment integrations

Checkout, subscriptions, invoicing and multi-currency flows wired to your provider of choice.

Fixed-scope build with a staged cutover

A list of the countries you collect money in and the payment methods buyers keep asking for.
01The situation

Payments work until a customer in Riyadh tries to pay with mada and cannot, or a refund takes three internal emails to process. Meanwhile finance matches gateway payouts to invoices by hand, and the two never quite agree.

Why it matters

Money collected automatically and reconciled without manual work.

The surface that sells, engineered like software.

What we build

Concrete artefacts, handed over and documented.

01

Gateway selection based on your markets and average order value, with the true cost per transaction of each option written down

02

Checkout integration with 3-D Secure handled, saved cards where they help, and failure messages a customer can act on

03

Webhook handling that treats the gateway as the source of truth, so a closed browser tab never loses a payment

04

Refunds, partial refunds and chargeback handling inside your own admin, not buried in the gateway dashboard

05

A reconciliation export matching payouts to orders and fees, in the format your accountant already works in

What changes

01

Buyers in each market can pay the way they normally pay

02

Finance reconciles a payout run in one sitting rather than a day

03

Payments stop going missing when a customer closes the tab at the wrong second

How it runs

Week 1

01Methods and gateway

We list the countries you take money in, the methods buyers ask for, and price the realistic gateway combinations.

Weeks 2–4

02Integration and webhooks

Checkout, authorisation, capture and the webhook layer that keeps your records true when the browser lies.

Weeks 5–6

03Reconciliation and go-live

Refund and chargeback paths tested with real transactions, the finance export agreed, then a staged switch of live traffic.
