AFIP / ARCA Configuration

How to link your company with fiscal services to issue electronic receipts.

Last updated: 2026-06-11

To be able to issue electronic invoices, your company must be correctly configured with fiscal services (AFIP/ARCA).

Important: this module usually requires participation from your accountant or Sarah support to complete all steps correctly.

Required data

In the company's fiscal record you must complete:

  • Tax ID (CUIT).
  • Tax condition (Registered Taxpayer, Monotax, Final Consumer, etc.).
  • Enabled point(s) of sale.
  • Certificates and keys necessary for communication with AFIP/ARCA (according to the scheme implemented by Sarah).

Automatic regime detection

When configuring ARCA, Sarah can detect the tax regime from the CUIT you enter:

  1. Enter the CUIT in the ARCA configuration form.
  2. The system queries available information and suggests the matching tax condition.
  3. Review the result before saving; your accountant can confirm it matches AFIP records.

This reduces manual errors when linking the company and speeds up initial setup.

Configuration validation

Once data is loaded:

  1. Run a connection test from the configuration module.
  2. The system will attempt to get the last authorized receipt to validate:
    • Connectivity.
    • Certificate validity.
    • Correct association of Tax ID and point of sale.

If everything is correct, you can start issuing receipts from POS or from the billing module.

Billing in POS

With ARCA connected, POS adapts billing options:

  • Receipt type selector: only shows types enabled for your regime and ARCA connection status.
  • Fiscal receipts: if ARCA is not configured or the connection fails, Sarah indicates which receipt types require fiscal linkage before issuing.
  • Regime information: panel with detected regime data to guide the operator.
