System Integration
Payment Integration
Payment gateway integration so payments are received, confirmed and matched to orders automatically - via gateways, bank transfers, virtual accounts and QRIS.
Challenges
Problems We Solve
Accepting payments is the easy part. The real work comes after: confirming each payment against the right order, handling expired and partial payments, refunds, and reconciling gateway reports with bank settlements. We integrate payment gateways and other payment methods so confirmation and reconciliation run without the finance team checking transfers one by one.
- Transfers are checked by hand against orders or invoices.
- Customers wait for someone to confirm their payment.
- Gateway reports, bank statements and orders do not match at month end.
- Every new sales channel needs its own payment setup.

FAQ
What people often ask about this service.
Which payment gateways do you work with?
We integrate the gateway or bank you choose; the choice depends on fees, settlement terms and the payment methods your customers use.
Can payments be confirmed automatically?
Yes. Verified gateway callbacks update the order immediately, so customers do not have to wait for a manual check.
Do you handle reconciliation?
Yes. Reconciliation compares gateway reports, bank settlements and orders, then lists the discrepancies that need follow-up.
