Online payments only help if every successful charge lands on the right subscriber or zone wallet. Start by configuring merchant credentials per company, then verify sandbox or live callbacks before opening the portal to customers.

Recommended flow
- Enable the gateways your merchants already use (bKash, Nagad, SSLCommerz).
- Map successful payments to invoice / balance updates automatically.
- Use payment reports filtered by zone, POP and staff for daily close.
- Optional: install bKash SMS Sync on the merchant phone for Make Payment SMS capture.
Export CSV or Excel at month-end so accounts and zone partners stay aligned.
