Brazil's services invoicing was uniquely fragmented — each of the country's 5,570 municipalities operated its own system with different:
- XML formats and API endpoints
- Portal interfaces for manual issuance
- Registration requirements and codes
- ISS (Imposto Sobre Serviços) calculation rules

ISS (Imposto Sobre Serviços) is a municipal tax on services, ranging from 2% to 5%. Key considerations:
- Where is ISS due? Generally in the municipality where the service provider is established, with exceptions for construction, cleaning, and security services (due where performed)
- Withholding: Some municipalities require the buyer to withhold ISS (ISS retido) when the provider is from another city
- Simples Nacional: ISS is included in the unified tax rate for small businesses
Invoicemonk supports the NFS-e Nacional platform with ABRASF 2.04 XML generation, automated ISS calculation by municipality, and a single integration point replacing the need for multiple municipal system connections.
