Invoice in a minute
and without keeping count by hand

A simple, standalone invoicing program. Issue the invoice with its sequential number and its VAT, and keep what you have collected, what is outstanding and what is overdue in sight. PRIETO One doesn't process payments or act as an intermediary: the money goes straight into your account, with no commission from us.

What it does today

Invoicing properly, which is plenty

This is what you can do with Billing from minute one, with no conditions and no small print. And always with one clear rule: your money is yours and goes straight into your account.

Standout feature
🔢
Sequential numbering, with no gaps

A yearly series like F-2026-0001, sequential and with no jumps. The system keeps it, not you, and there is no way to repeat a number by accident.

🧮
VAT on every invoice

At 21 %, 10 %, 4 % or exempt. Net, VAT and total are worked out on their own and stored on the invoice, not on a separate sheet.

🚦
Draft, sent, paid

Marking it sent sets a due date fifteen days out, and past that date it shows as overdue. Marking it paid is one click.

📊
The four figures of the month

Collected this month, outstanding, overdue and total invoices issued. Worked out from your invoices, right at the top, always.

🔎
Filter by status

All, draft, sent, paid or overdue. To know who you need to chase this week you do not have to go looking anywhere.

👥
The client is typed in once

Invoice a client you already have in Clients, or type a new name: the record creates itself and from then on it lives in your client list.

What we are building

None of this is available yet. It is here so you know where Billing is heading, not for you to buy today. If you need one of them, tell us and it moves up the list.

🔔
Automatic payment reminders

Reminders before and after the due date, in your tone and with your brand. Today Billing sends no email at all: the invoice is marked sent, but you are the one sending it.

In development
🎨
The invoice as a PDF, with your logo

A template with your brand and the full issuer and client fields. Today the invoice lives in the panel; it cannot be downloaded or printed yet.

In development
💳
Connect your payment gateway

Stripe, PayPal, IBAN and the Redsys virtual terminal, the last one subject to a feasibility study. You will receive the payment: PRIETO does not process payments or add commission.

In development
🌍
Multi-currency

Invoicing in dollars, pounds or whatever currency you need, formatted for each country. Today every invoice is issued in euros.

In development
📈
Profit calculation

Entering the cost of what you sold and your fixed costs — rent, staff, energy — to see the real margin on each sale, not just what you invoiced.

In development
🧾
Cash-up

Cashing up at closing, working out the change and recording what was taken by card and in cash, so you know whether the till balances without reaching for a calculator.

In development
📚
Ledger and per-country compliance

An income and expenses ledger, and adaptation to the rules of each country where we operate. Today Billing stores invoices; it keeps no ledger.

In development · needs certification
VeriFactu

The verifiable invoicing system of the Spanish tax authority. Billing is not a VeriFactu system today and it will not be one until it passes certification. If you need it now, do not take on Billing for that.

🔗
The appointment, turned into an invoice

Turning a Booking appointment into an invoice with one click. For now the invoice is created by hand, although the client is indeed shared between the two tools.

The list

Every invoice, with its status in plain sight

You know at any moment whether an invoice is still a draft, whether you have marked it sent or whether it has been paid, and which ones have gone past their due date. You receive the payment: PRIETO One does not process payments or act as an intermediary, and adds no commission.

  • Draft · sent · paid statuses, and an overdue warning
  • Sequential numbering, and the VAT stored on every invoice
  • The money goes straight to your account, no middlemen
