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 breakdowns

Curious how others here approach customer-facing billing UX, especially around access control and audit-ability. Happy to answer questions or drop-in by our community if you have anything particular - http://bit.ly/4huvkDm
