    InvoicingAPI is finally ready▲20

    After a lot of personal hardships over the past year, I can finally say that InvoicingAPI is ready for public use. It's a platform where you can create beautiful, customizable and dynamic, tax-compliant invoices with payment links built in, so your clients pay you faster. In your dashboard you can see your payments and payouts to your bank. This is just an initial release and plenty of features are in the pipeline, like an online builder, automated sending, 3rd party app integration, etc. Feel free to poke around and let me know your thoughts!

    Nomod payment integrated into usage-based billing stack▲9

    Hi HN, 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…
