ARCA (AFIP) invoicing

The system issues tax documents valid in Argentina by integrating directly with the ARCA (formerly AFIP) web services: electronic invoices with a CAE, credit and debit notes, without leaving the system and without re-entering anything by hand on another site.

What the module does#

• Issues electronic invoices (A, B or C depending on your tax status and the customer's) with their CAE (Electronic Authorisation Code) and expiry date.
• Issues credit and debit notes linked to their original documents.
• Keeps the sequential numbering automatically, by asking ARCA for the last authorised document.
• Stores every issued document with all its data: type, number, date, recipient, amounts (net, VAT, total), CAE and status.
• Works in two environments: Testing (sandbox, no fiscal validity) and Production (real documents).

Initial setup#

1. Go to the panel's ARCA settings section (requires the Settings permission).
2. Enter your company's tax details: CUIT, legal name and point of sale.
3. Generate the certificate request (CSR) from within the system.
4. Use that file to obtain the digital certificate on the ARCA site, then upload it to the system.
5. Use "Test connection" to check that authentication with ARCA works.
6. Start in the Testing environment: issue trial documents until you're confident, and only then switch to Production.

Important: the point of sale you configure must be registered with ARCA for electronic invoicing (web services).

Issuing an invoice from a sale#

1. When you finish a sale in the POS (or from an order's detail view), choose issue document.
2. Specify the document type and the recipient's details (end consumer, or the customer's CUIT/DNI).
3. The system sends the request to ARCA and gets the CAE back on the spot.
4. The document is saved and linked to the sale, ready to print or send.

Credit and debit notes#

To void or adjust an issued invoice, generate a credit note (or debit note) from the original document: the system links it automatically to the document it corrects, as ARCA requires.

Reviewing issued documents#

• Every document is kept in the ARCA documents list, with its status, number, recipient, amounts and CAE.
• You can also ask the AI assistant to show you one: "show me the last invoice" or "the invoice for order 1043".

Common errors#

If ARCA rejects a document, the system shows the reason in a clear message (for example: invalid recipient details, point of sale not enabled, numbering problem). The rejected document is recorded with its status so you can correct it and retry.
