Products that do what A customer billing portal built to reduce "can you resend the invoice? does
Hey HN, A recurring problem we kept running into with billing systems was the human layer around them. Customers asking: “What’s my current balance?”“Which invoice is pending?”“Why did usage spike last week?”And the answer was usually someone digging through dashboards, exporting PDFs, or pasting screenshots. So we built a read-only customer billing portal inside Flexprice (open-source metering + billing infra). It gives customers visibility into: subscriptions and billing periodsprepaid wallet balances and credit transactionsinvoices (status, search, download)feature-level usage and cost…

Hey HN, I’am Koshima, co-founder of Flexprice (https://flexprice.io/). Flexprice is an open source monetization platform for AI & Agentic companies. You can build usage-based, credit-based, or hybrid pricing models with full control. Usage-based billing works on paper, but breaks fast in production: (1) High-volume data (e.g., 10k API calls/sec from AI inferences) breaks naive pipelines, dropping events and causing underbilling or customer complaints.

You know how it goes – you have got a bunch of payment providers, each with their own fee reports, and trying to make sense of all that mess is quite challenging and complex. We thought, why not just build something that pulls all those fee reports together, cleans them up, and makes them actually understandable? So we built a tool that pulls in fee reports from multiple providers, standardizes fee names, and makes it easier to understand all fee types. You can drill down to see the exact…

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…
