If your provider is not here, ask: most expose an API and we have connected many of them. Names and marks belong to their owners. We build with these tools; no partnership, endorsement or certification is implied.
Payment Gateway Integration
A payment that fails, hangs or lands in the wrong account is a customer lost. We integrate payment gateways properly: the checkout, the callback that confirms payment, the receipt, the refund path and the report your accountant wants at month end.
We build payments so a purchase lands in the app or the customer's account the moment payment completes. Stripe and PayPal cover cards and wallets worldwide; local gateways such as KHQR cover customers who pay that way. We work from each gateway's own documentation and sandbox, and test end to end before a single real transaction.
Why have it built by Baal
Local and international, one checkout
Stripe, PayPal, Apple Pay, Google Pay and local gateways such as KHQR side by side, so every customer has a method they trust.
Confirmed, not assumed
Server-side verification of every payment callback, so credits, orders and memberships are released only when the money has actually arrived.
Reconciles at month end
Transaction records, refunds and payouts that match the gateway statement, exported for your accountant.
What we build
Stripe and PayPal
Cards, wallets and subscriptions for customers anywhere in the world.
Apple Pay and Google Pay
One-tap payment on phones, in your app or at your website's checkout.
Local gateways
The bank and QR payments your customers use where you trade, such as ABA PayWay and Bakong KHQR, with callbacks and refunds handled.
Subscriptions, credits and top-ups
Recurring billing, credit bundles and memberships that update the account the moment payment clears.
Reconciliation and reporting
Statements, exports and dashboards that match what the gateway paid out.

How we work
- 01
Talk
You tell us what you need, on WhatsApp, Telegram or the form, and you are talking to the team from the first message. We ask questions until we understand the problem properly — usually the same day.
- 02
Quote
We put the scope, the fee and the timescale in writing before any work begins. No surprises later.
- 03
Build
We build in stages and show you working software as it progresses, not only at the end.
- 04
Support
After release we stay on for updates, fixes and changes as your business grows. Ask for a change and it is done in days, not queued for next quarter.
Frequently asked questions
Do you open the merchant account for us?
No. Merchant accounts are opened by you directly with Stripe, PayPal or your local gateway, because the account and the money are yours. We tell you what to ask for, then integrate the credentials they give you.
Can you add payments to an app or site another team built?
Yes. We integrate into existing code regularly. We review what is there, agree the approach and build the payment flow with proper verification and error handling.
Can one checkout offer several methods?
Yes, and we recommend it. A single checkout that offers cards, Apple Pay, Google Pay, PayPal and the local methods your customers use loses fewer sales than making customers hunt for a way to pay.
