Automatic invoicing with ARCA from Sodapp

With automatic invoicing enabled, every order you deliver generates its own electronic invoice: Sodapp requests it from ARCA, gets the CAE (the authorization code that makes an invoice valid in Argentina) and makes it available to your customer. You do nothing.

For this to work there are two procedures you need to complete yourself on the ARCA site. About 15 minutes, once. We handle everything else.

A note on language: the ARCA portal is only available in Spanish. Service and field names are kept in Spanish below so you can find them on screen, with an explanation of what each one means.

We will never ask for your clave fiscal (your tax credentials). Not by email, phone or WhatsApp. You complete both procedures yourself on the ARCA site. If someone asks for it claiming to be from Sodapp, it is not Sodapp.

Before you start

Have these at hand:

• Your CUIT (your tax ID number).
• Your clave fiscal nivel 3 — the same credentials you used to verify your business on WhatsApp. Level 3 is the security tier ARCA requires for this.
• Whether you are registered as monotributo (simplified regime) or responsable inscripto (general VAT regime). Your constancia de inscripción states it, or your accountant can tell you.

Step 1: create a punto de venta for automatic invoicing

A punto de venta is the invoice series your invoices are numbered from. You need a new one, dedicated to this.

1. Go to arca.gob.ar and log in with your clave fiscal.
2. Look for the service Administración de puntos de venta y domicilios (management of sales points and addresses).
3. Select your business and open A/B/M de puntos de venta (add, edit and remove sales points).
4. Click Agregar (add) and fill in:
   • Número: the one the system suggests, or the next free number. Write it down.
   • Nombre de fantasía (display name): use Sodapp, so you recognise it later.
   • Sistema: pick the option that says Web Services. Depending on your tax regime it appears as Factura Electrónica - Monotributo - Web Services or as RECE - Facturación Electrónica - Web Services.
   • Domicilio (address): the same as your business address.
5. Save.

It has to be a new punto de venta. ARCA does not allow a sales point already used for Comprobantes en línea (the manual web invoicing tool) to be reused for web services. If you try to reuse yours, invoices will fail. Creating a new one is free and commits you to nothing.

Write down the number you got: it is one of the details you will send us.

Step 2: authorize Sodapp to issue invoices on your behalf

This tells ARCA that Sodapp may request invoices using your CUIT. It is the same thing any online invoicing system does.

1. On arca.gob.ar, open the service Administrador de Relaciones de Clave Fiscal (the tool that manages who may act on your behalf).
2. Click Nueva Relación (new relationship).
3. Under Servicio, click Buscar (search) and choose ARCA → WebServices → Facturación Electrónica.
4. Under Representante (representative), enter Sodapp's CUIT. We send it to you by email or WhatsApp when you enable invoicing, along with the rest of your account details.
5. Confirm. ARCA shows you a receipt and you are done.

Step 3: send us three details

Write to us with:

1. Your CUIT.
2. The punto de venta number you created in step 1.
3. Whether you are monotributo or responsable inscripto.

We configure everything and verify against ARCA that the authorization went through. If something failed, we tell you exactly what to check: you do not have to verify anything yourself.

What Sodapp does for you

Everything technical:

• Digital certificates and the connection to ARCA.
• Verifying that your authorization works before issuing anything. If it is not ready, invoicing does not turn on: we would rather issue no invoices than issue broken ones.
• Requesting the CAE for each invoice and keeping numbering sequential, with no gaps.
• Building the PDF with the QR code Argentine law requires.
• Making the invoice available to your customer, on the same link they already use to order.
• Issuing the nota de crédito automatically when an order is cancelled or returned.
• Retrying if ARCA is down, without ever duplicating an invoice.

You just deliver the order as usual.

You decide who gets invoiced

From the panel you choose between three options:

• Invoice electronic payments: an invoice is issued when payment was made by bank transfer or payment link. Cash payments are left to your judgement.
• Invoice everything: every delivered order gets its invoice.
• Only some customers: you mark them one by one — for example the companies that require an invoice from you.

You can switch options whenever you want, and you can always flag an individual customer to always be invoiced, regardless of the general setting.

Issuing invoices is your obligation as a business, not Sodapp's. We are the tool that automates it; how you configure it and what you invoice is a decision for you and your accountant.
