Payment happens on the phone

Mobile money is part of your customers’ daily lives. An app that only offers cards or cash misses how many people actually pay.

02

Reconcile automatically

The real gain is not just taking payment but reconciling it: matching every payment to an order, handling failures and refunds, and producing a reliable statement for accounting. Operator APIs and payment notifications make this possible.

03

Design offline first

A network drop should never stop a sale. A progressive web app can record operations locally and sync them when the network returns. This is decided in the architecture: identifiers, conflicts, order of operations.

04

Test on real phones

Test on your users’ devices and networks, not just at the office. Light pages, optimized images and short journeys make the difference on 3G.
