# AFIP / ARCA Configuration

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.
