Brinta issues the electronic tax documents (DTE) you need in Guatemala under the FEL regime and has them certified with the SAT for you. What changes from one document to another is the document_type and invoice_type you send.

Certification is asynchronous: the request returns status: "received" and the document moves to created (certified) or failed. Get the result with GET /invoices/{invoice_id}.

This page covers the setup and the fields every document shares. Each document type has its own page:

[GT] Sales Documents: Factura, Factura Cambiaria and Recibo
[GT] Credit and Debit Notes
[GT] Factura Especial

📮 Postman: every document type has a ready-to-send request in the Invoicing - Guatemala folder of the Brinta Testing collection.

The DTE issuer is filled from the company you send in supplier_company_id. Brinta sets it up with you during onboarding. Keep this data up to date:

NIT and IVA affiliation
ISR regime. The one currently supported is Régimen Opcional Simplificado sobre Ingresos. Contact Brinta if your company is under another ISR regime.
Legal name and commercial name (the establishment name printed on the DTE)
Establishment code
Address, with the department
