We just shipped a Nomod integration in Flexprice. For context, flexprice is an open-source billing system that handles invoices, usage, and credit wallets. One gap we wanted to close was supporting region-specific payment providers without breaking billing state.

With this integration: - Invoices finalized in Flexprice can be synced to Nomod - A hosted Nomod payment link is generated for the invoice - Payment status updates flow back into Flexprice - Invoices and payment records stay in sync - Credits (if applicable) are applied only after payment succeeds

This keeps billing logic simple and avoids reconciliation issues later. There's no demo yet, but docs are live here: https://docs.flexprice.io/integrations/nomod/

Happy to answer questions or hear feedback from folks who've built billing or payment integrations before or feel free to join our open-source community if that interests you : http://bit.ly/4huvkDm
