A REST API for your receivables that doesn’t fight you.

Sandbox in minutes, production in days. Submit invoices, track collection status via webhooks, and pull clean reconciliation data — with a sandbox that mirrors production 1:1, including arrears scenarios.

Sandbox login

Spin up a free sandbox account with mock invoices, test debtors, and a full set of programmable scenarios — from partial payments to simulated arrears and defaults.

API documentation
