Issue fiscal documents from a single API call.
NFe · NFSe · Multi-tenant · Multi-jurisdiction
Every business selling in Brazil has to issue fiscal documents — and the government side of that (tax authorities, digital certificates, XML schemas, city-by-city rules) is a project on its own. Stackin turns it into one API key per company: create the key on the dashboard, issue with one call, get a valid document back. No certificates to manage, no bureaucracy to learn — that's on us.
