Invopop’s Argentina app provides comprehensive integration with ARCA (Agencia de Recaudación y Control Aduanero), Argentina’s national tax and customs authority. This app streamlines compliance with Argentina’s mandatory electronic invoicing system, enabling automated invoice submission, authorization, and reporting through ARCA’s clearance model.

Key Features

1. Workflow Automation: This app provides automated workflows for registering suppliers and issuing invoices through the ARCA system.
2. Real-Time Clearance: Every invoice is submitted to ARCA for validation and receives a unique CAE (Código de Autorización Electrónico) code, ensuring compliance with Argentine e-invoicing regulations.
3. Multiple Invoice Types: Support for Factura A (B2B), Factura B (B2C), Factura C (Monotributistas), and Factura E (Exports).
4. Supplier Registration & Verification: Generate registration links where suppliers upload their certificates and sign agreements to enable invoice reporting.
5. PDF Generation: Invoices are generated with all mandatory fields, CAE codes, and QR codes as required by Argentine invoicing legislation.
6. WSFE Integration: Direct integration with ARCA’s Web Services de Factura Electrónica for automated invoice submission and authorization.
7. Sequential Numbering: Automatic invoice numbering management to maintain required sequential order by punto de venta (point of sale).

Make sure to check out our ARCA Supplier Onboarding guide and ARCA Invoicing guide for instructions on how to set up and use these actions in your workflows.

FAQ

Invoicing questions

What invoice types are commonly used in Argentina?

Factura A (B2B between Responsables Inscriptos), Factura B (consumers and exempt entities), Factura C (Monotributistas to anyone) and Factura E (exports). Type is determined by the issuer’s tax regime and the customer’s classification — Invopop selects the right one automatically when both are set.

How are ARCA invoices delivered?

Most ARCA-cleared invoices are delivered as PDFs with the CAE printed on them, though the underlying XML is also available on request. Invopop can convert the XML into GOBL for downstream processing; PDF-only documents need OCR or manual capture.

How does invoice numbering work in Argentina?

Argentine invoices use a two-part numbering system: XXXXX-YYYYYYYY

• Punto de Venta (POS): A 5-digit code (e.g., 00001) that identifies the point of sale or electronic invoicing method.
• Sequential Number: An 8-digit code (e.g., 00000001) that increases by 1 with each invoice.

The sequence must be continuous with no skipped or repeated numbers. Each invoice type (A, B, C) and POS combination has its own independent sequence. For example, Factura A from POS 0001 starts at 00001-00000001, while Factura B from the same POS would also start at 00001-00000001.

Invopop automatically manages sequential numbering for each punto de venta.

What is a Punto de Venta (point of sale)?

A Punto de Venta (POS) is a 5-digit code that identifies where invoices are issued from. In electronic invoicing, it represents the electronic invoicing method or channel (e.g., Web Service, ARCA portal).

Each POS has its own independent invoice sequence for each invoice type. You must register your punto de venta with ARCA before you can issue invoices through it in production. In the sandbox environment, you can use test punto de venta numbers without registration.

Do I need different puntos de venta for different invoice types?

No, you can use the same punto de venta for different invoice types (Factura A, B, C, etc.). However, each invoice type will have its own independent sequential numbering within that punto de venta.

For example, using POS 00001:

• Factura A: 00001-00000001, 00001-00000002, 00001-00000003…
• Factura B: 00001-00000001, 00001-00000002, 00001-00000003…

What is WSFE and how does Invopop use it?

WSFE (Web Services de Factura Electrónica) is ARCA’s web service infrastructure for automated invoice submission. ARCA provides several web services:

• wsfev1: For invoices A, B, C, and M without item detail
• wsmtxca: For invoices A and B with item details
• wsfexv1: For type E (export) invoices

Invopop integrates with these services to automatically submit your invoices to ARCA and receive CAE authorization codes in real time.

What happens if ARCA rejects my invoice?

If ARCA rejects an invoice, you’ll receive an error message explaining the reason for rejection. Common reasons include:

• Invalid or unregistered CUIT
• Missing required fields
• Incorrect tax calculations
• Sequential numbering errors
• Invalid punto de venta

Review the error message, correct the issue in your GOBL document, and resubmit the invoice. The rejected invoice does not count toward your sequential numbering, so you can use the same number after correction.

Where do I find Argentina-specific GOBL documentation?

See the Argentina tax regime in GOBL for tax IDs, tax categories, and AFIP/ARCA-specific extensions. The ar-arca-v1 addon documents required fields for invoice submission to ARCA.

Registering supplier questions

Do I need to upload digital certificates to Invopop?

Yes, to issue invoices through ARCA’s web services, you need to upload your CSD (Certificado de Sello Digital) to Invopop. This certificate is issued by ARCA and is used to authenticate your requests to their system.

The registration process involves:

1. Generating a certificate signing request (CSR) with ARCA
2. Downloading the certificate and private key
3. Uploading them to Invopop through the supplier registration flow

See our ARCA Supplier Onboarding guide for detailed instructions.

What information is required to register a supplier?

To register a supplier for ARCA invoicing, you need:

Company Information:

• Legal name (Razón Social)
• CUIT (tax ID)
• Fiscal address
• Economic activity code
• Tax classification (Responsable Inscripto or Monotributista)

Digital Certificates:

• CSD certificate (.crt file)
• Private key (.key file)
• Key password (if applicable)

See our ARCA Supplier Onboarding guide for detailed registration instructions.

How long does supplier registration take?

The supplier registration process typically takes a few minutes once the supplier has their digital certificates ready. The steps are:

1. Generate a registration link in Invopop
2. Supplier uploads their certificate and key
3. System validates the credentials with ARCA
4. Registration is complete

The longest part is usually obtaining the digital certificate from ARCA, which can take a few days if the supplier hasn’t done it before.

Can I register multiple puntos de venta for one supplier?

Yes, a single supplier can have multiple puntos de venta. Each punto de venta operates independently with its own sequential numbering for each invoice type.

When registering a supplier, you specify which punto de venta to use. You must register each punto de venta with ARCA in production before using it to issue invoices.

What happens if a supplier's certificate expires?

Digital certificates issued by ARCA have an expiration date. When a certificate is about to expire, the supplier must generate a new one through ARCA’s portal and upload it to Invopop.

To update an expired certificate:

1. Obtain a new certificate from ARCA
2. Use the supplier registration workflow to upload the new certificate
3. The new certificate will replace the old one

It’s recommended to renew certificates before they expire to avoid disruption to your invoicing process.

Does Invopop support white-label invoicing in Argentina?

Yes, Invopop supports white-label (B2B2B) operations in Argentina. This means you can issue invoices on behalf of your clients using their CUIT and digital certificates.

This is particularly useful for platforms and software providers who want to offer invoicing services to their customers without requiring them to integrate directly with ARCA.

Each supplier (your client) needs to complete the registration process with their own certificates, and then you can issue invoices on their behalf through Invopop’s workflows.

What certificates are required to integrate with ARCA?

A CSD (Certificado de Sello Digital) issued by ARCA, consisting of a .crt X.509 certificate and the matching .key private key. Both files are uploaded together; the certificate must be valid (not expired, not revoked) and authorized for the WSFE web service.

How do I onboard a new supplier in Argentina?

Generate a registration link via the ARCA Register Supplier workflow, send it to the supplier, and have them upload their CSD certificate and private key. Once validated, the supplier is ready to issue. See the ARCA Supplier Onboarding guide.

How are supplier credentials stored in Invopop for Argentina?

The CSD certificate (.crt) and private key (.key) are stored encrypted. Invopop only uses them to authenticate WSFE requests on the supplier’s behalf and never returns the key in API responses.

Factura A - Registered taxpayer to registered taxpayer (B2B)

Factura A is issued by registered taxpayers (Responsable Inscripto) to other registered taxpayers or monotributistas. This invoice type includes VAT broken down separately.

Notice:

• the minimal version (arca-invoice-A.min.mdx) contains only the essential fields required to create the Factura A,
• the ar-afip-v1 addon ensures the document will be validated using the AFIP rules built into the GOBL library,
• both supplier and customer must be registered taxpayers with valid CUIT numbers,
• there are no totals or calculations in the minimal version; all these will be calculated automatically when running gobl build,
• the built version (arca-invoice-A.mdx) shows the normalized document with calculated totals, line item sums, IVA breakdowns shown separately, and automatically generated fields, and,
• the invoice will be submitted to AFIP for authorization and receive a CAE (Código de Autorización Electrónico).

Factura B - Registered taxpayer to final consumer (B2C)

Factura B is issued by registered taxpayers (Responsable Inscripto) to final consumers, exempt entities, non-categorized subjects, and foreign tourists. VAT is included in the total price.

Notice:

• the customer is typically a final consumer (Consumidor Final) and may not have a CUIT,
• the minimal version contains only essential fields; gobl build handles all calculations,
• when running gobl build, the system automatically calculates totals with IVA included in the price (not shown separately as in Factura A),
• the built version shows the normalized document with calculated totals where VAT is included in the final amounts,
• the ar-afip-v1 addon applies Factura B specific rules and validations, and,
• the invoice will be submitted to AFIP for authorization and receive a CAE.

  ]
}

Factura C - Monotributista invoice (SMB2B)

Factura C is issued by monotributistas (simplified tax regime for small businesses and freelancers) to any type of customer. This invoice type does not break down VAT separately.

Notice:

• the supplier is registered under the monotributo regime, which is a simplified tax system for small businesses,
• the minimal version contains only essential fields; totals are calculated by gobl build,
• when running gobl build, the system automatically calculates totals without breaking down VAT separately (VAT is included but not itemized),
• the built version shows the normalized document with calculated totals where no VAT breakdown is shown, as monotributistas don’t separately charge VAT,
• the ar-afip-v1 addon applies Factura C specific rules and ensures compliance with monotributo requirements, and,
• the invoice will be submitted to AFIP for authorization and receive a CAE.
