FEL setup

Configure electronic invoicing (FEL) from Business → Billing & electronic invoicing. Authorized staff can set legal billing details and the credentials your certifier issued.

Billing information​

Complete these fields for invoices and tax documents:

  • Legal name — Registered business name as it appears on SAT documents.
  • Tax ID (NIT) — Your business tax identification number.
  • Country — Guatemala (GT) for standard FEL flows.

FEL credentials​

Your certifier (for example Digifact) provides:

  • FEL certifier — Which provider issued your access (see below).
  • Username and password — Certifier portal credentials.
  • Access code — Establishment or access code from the certifier.
  • Token — API token used for certification (stored encrypted on the server).

Leave password blank when saving if you do not want to change the stored password.

Certifier dropdown​

The FEL certifier field is a dropdown labeled Select FEL certifier.

Why only one (or few) options appear​

FlowPOS maintains a registry of all SAT-authorized certifiers in Guatemala (legal names and NITs used on receipts and reports). The billing screen only lists certifiers FlowPOS can connect to today—those with a live API integration.

If you see a single option such as DIGIFACT SERVICIOS, S. A., that is expected: it is currently the only integrated certifier. Other SAT certifiers may exist in the registry but are not selectable until FlowPOS adds support for them.

You cannot save billing settings with a certifier that is not integrated; the system will reject the change.

What to do if your certifier is not listed​

  1. Confirm which certifier your SAT authorization is under (check your certifier contract or portal).
  2. If it is Digifact, select it and enter the credentials Digifact gave you.
  3. If it is another provider (for example Infile, Megaprint), contact FlowPOS support—integration may be planned or in progress. Do not assume all SAT certifiers appear in the list.

On the same billing page, configure SAT phrases and establishment codes used on printed receipts and DTEs. Location-level tax numbers can override establishment codes per branch.

After setup​

Once billing and FEL credentials are saved:

  • Retail sales can certify invoices automatically when FEL is enabled for the business.
  • Restaurant bills follow the restaurant FEL workflow (developer reference).
  • Credit and debit notes require a configured certifier and valid credentials.
