Electronic invoicing

Your invoices with a CAE in one click, sent to the customer right away

You pick the customer or type their CUIT, enter what you sold, and the invoice goes out authorized by ARCA. It reaches them by email or WhatsApp, gets recorded with its payment, and at the end of the month your accountant gets everything in order.

  • A, B and C invoices with an ARCA CAE
  • Complete customer data from the CUIT
  • Sent by email or WhatsApp when issued

Monthly plan in dollars · Your invoices and your customers stay yours
Less time on ARCA

You invoice from where you sell, without copying data from one screen to another.

The system requests authorization from ARCA and saves the CAE on every invoice. You choose the customer and what you sold; the number, the totals and the sending take care of themselves.

  • Invoice without leaving the system

    You choose the invoice type, the customer and the line items. ARCA authorizes it and the CAE is saved with its expiration date.

  • Data by CUIT

    You type the CUIT and the business name, address and VAT status fill in, taken from ARCA’s registry.

  • Sent to the customer

    The PDF with the QR code reaches them by email or WhatsApp as soon as it’s issued. If they lose it, you resend it from their record.

  • Payments recorded

    Each invoice shows whether it’s paid, partially paid or pending, and each customer has their own running account.

  • Purchases in order

    You enter your suppliers’ invoices with their VAT and due date, and you know what you’ve paid and what’s still owed.

  • Ready for your accountant

    The sales and purchases files for the digital VAT ledger, and a spreadsheet with every invoice of the month.

Custom

Connection to your management system, more than 10 points of sale or special invoices: we evaluate it and put together a proposal.

Request a proposal

Are you an accountant?

If your clients invoice with kaptativa, you receive their invoices organized in one place. We set up an arrangement for your firm.

Let’s talk

Switch between dollars and pesos with the selector at the top. Reference exchange rate: Argentina's official dollar rate of AR$ 1,560 (10/26/2026).

Every invoice issued, sent and recorded

Invoices, credit notes and debit notes with their data, their CAE and their payment, all in one place.

Your customer gets the invoice and pays it from their phone. You see what you’ve collected and what’s still due.

1 · Your customer

On your customer’s phone

They receive the invoice with the details, the PDF and a link to pay it with Mercado Pago. When they pay, the payment is recorded automatically.

2 · You, in the dashboard

In your dashboard

Each invoice with its payment status and each customer with their running account. You record partial payments, bank transfers or cash.

For your accountant

End of month without gathering papers for the firm

Your accountant logs in with their own user or receives the month’s files: sales and purchases in the digital VAT ledger format, plus a spreadsheet with every invoice. They keep calculating and filing as always; you stop putting folders together.

  • Sales and purchases files for the digital VAT ledger
  • Read-only user for your accounting firm
  • Monthly spreadsheet with every invoice and its CAE
Automatic invoicing

The invoice goes out on its own with every sale, appointment or fee

If you sell through your online store or collect appointments and fees with kaptativa, each payment generates its invoice at the point of sale you choose and sends it to the customer. You only review the ones that need a piece of data.

  • Automatic invoice with every payment
  • One point of sale for each channel
  • Alert when data is missing to issue
Included in the Volume plan

Let the customer ask for their invoice on WhatsApp and get it right away

The WhatsApp agent recognizes each customer, resends their invoices, tells them how much they owe and sends the payment link. If they ask for an A invoice, it takes the CUIT and leaves the invoice ready for you to review and issue. Tax questions go to your team.

  • Resends invoices and credit notes instantly
  • Reports balances and sends the payment link
  • Collects the data for an A invoice and leaves it ready

Ask us

From the first conversation to your system up and running

Three steps, with a fixed proposal before we start.

  1. 1

    We learn how you invoice

    Your VAT status, how many invoices you issue per month, where you sell from and who handles your accounting.

  2. 2

    We guide you through ARCA

    With your ARCA tax login (clave fiscal) you generate the certificate and the point of sale for the system; we guide you step by step on a video call.

  3. 3

    You issue your first invoice

    We load your customers and products, test a real invoice and teach your team how to use the system.

FAQ

What people ask us before getting started

Have another question? Write to us and we'll answer for your case.

Ask your question
What do I need to start invoicing from the system?

A digital certificate and a point of sale for web service e-invoicing. Both are set up in ARCA with your tax login (clave fiscal, level 3 or higher) and we guide you through every step. Your clave fiscal is never entered or stored in kaptativa.

Does it replace my accountant?

No. kaptativa issues, sends and organizes your invoices, but it doesn’t give tax advice, calculate taxes or file returns. Which invoice applies to you, at what tax rate and under which regime is for your accountant to decide.

Can my accountant see the information?

Yes. On every plan they get their own read-only user to see invoices, purchases and payments. From the Small Business plan on, they can also download the sales and purchases files in the digital VAT ledger format.

Are there costs besides the monthly plan?

Authorizing invoices with ARCA is free. Third-party costs do apply to Mercado Pago payments, which carry their own fee, and to WhatsApp messages sent through the official API, which Meta charges per message at its current rate. Sending by email is included.

What happens with my numbering and the customers I already have?

To invoice from the system, a new point of sale is registered in ARCA, with its own numbering, and the one you were using stays as it was. We import your customers and products from spreadsheets: the data belongs to your business and you can export it whenever you want.

Does it work if I’m a monotributista?

Yes. The Monotributo plan issues C invoices with a CAE and sends them to the customer. If you later become VAT-registered, you switch to the Small Business plan and start issuing A and B invoices without re-entering anything.

Does the AI agent issue invoices on its own?

No. It resends invoices that were already issued, reports balances and sends the payment link. If a customer asks for an A invoice, it collects the data and leaves the invoice ready for you to review and issue. Tax questions go to your team.

Every sale with its invoice, every invoice with its payment.
