Django + DRF core for billing merchants and settling with MFS and bank partners: a double-entry ledger with an enforced debits-equals-credits invariant, fee schedules with VAT, invoices, settlement batches with an approval workflow and CSV reconciliation.
This page is a static API reference built from the service's exported OpenAPI document on every push to main; there is no backend behind it, so requests cannot be sent from here. Open the Codespace to run the real service with demo data, or deploy your own copy to Render. All endpoints need Authorization: Token <key>; the Codespace prints the demo token and admin login (demo / demo12345) into .demo-credentials.txt.
