Factura ARCA with TusFacturasAPP for WooCommerce — ARCA invoices from orders in Argentina

Factura ARCA connects a WooCommerce shop to your TusFacturasAPP account, an e-invoicing service for ARCA (formerly AFIP) in Argentina. An order becomes Factura A, B or C, and the CAE and PDF sit right on the order. TusFacturasAPP is the provider of that service, and the plugin only passes data to it. This module is not affiliated with or endorsed by TusFacturasAPP.

This plugin has never worked with real TusFacturasAPP. The same author wrote that server, so it may repeat our mistakes. On 02.11.2026 the service site refused requests from our addresses in Ukraine (Cloudflare 403) and from the nodes we checked in Vietnam and Singapore. From nodes in the USA, Brazil, Europe, Japan and India it answered. Our check had no node in Argentina. The shop server must reach www.tusfacturas.app: if it cannot, the plugin says so instead of staying silent. Try the plugin on an API DEV account first.

The plugin makes no promise of legal compliance and is not tax advice. The documents are fiscal and cannot be undone: check the types, the IVA rates and the way of booking with your accountant.

What the buyer sees

The checkout has an “I need an invoice with my data” box. Without it the buyer sees nothing new. With it the document type and number, the IVA condition and the name open up. A wrong CUIT check digit, or a registered taxpayer without a CUIT, stops the order with a plain sentence and the cart stays.

In Pro the buyer sees the PDF on the order page, even as a guest through the order link.

What the admin gets

In the settings you enter the API keys, the point of sale, your CUIT and your IVA condition, and a button says whether the service answers. The page shows the webhook address for TusFacturasAPP.

The order shows which document will be issued and what stands in the way, the issue button, then the queue, CAE, PDF and a link to check at ARCA. If ARCA refuses, the reason shows there too, next to the buttons to resend, change the date and delete.

In Pro the document goes out by itself on the chosen status, and a refund becomes a credit note.

How it works, step by step

1. You enter the API keys, the point of sale and your IVA condition, and test the connection.
2. You paste the webhook address into TusFacturasAPP.
3. The buyer leaves data at checkout, or does not.
4. You press Issue on the order, or Pro does it on the status.
5. The document joins the queue and the webhook brings the CAE.
6. The CAE and PDF sit on the order.

Under the hood

• The asynchronous queue only: the service docs recommend it, and documents are not issued twice if an answer is lost.
• Tokens are kept encrypted and not shown back.
• The PDF is kept on the site, because the service links are temporary.
• The total follows the documented rounding rules, so the service does not refuse the document.
• Version 1.0 has no Factura E, FCE MiPyME or IIBB perceptions.
• A buyer abroad does not get an invoice automatically by default.
