Could you build this?

Partial The Cloudflare-hosted wrapper around the public national NFS-e API is straightforward to vibe-code, but correct invoice issuance depends on ICP-Brasil digital certificate handling and municipal tax rules that require fiscal domain expertise.

What it would actually take: The stack is a Cloudflare Worker or similar backend that signs XML requests with a client's A1 or A3 certificate and calls the Sistema Nacional NFS-e endpoints, with a simple UI for issuing and cancelling notes. The hard part is getting tax logic right across regimes, service codes, municipalities, and schema changes, which calls for a Brazilian tax or accounting specialist and test cases validated against real government responses.
