**Every invoice you issue in Euskadi must go through TicketBAI**, a system that sends it to your Hacienda as you create it. Each territory offers a free official app for this.

## Before you start

- [Your Hacienda registration](https://autonomo.eus/steps/register-hacienda)
- Your digital ID: [BakQ](https://autonomo.eus/steps/bakq) or your [FNMT certificate](https://autonomo.eus/steps/fnmt-certificate)

## What it unlocks

- [Issue your invoices](https://autonomo.eus/steps/invoices)
- In Bizkaia, your invoices go straight into your record book (*LROE*)

## How to do it

1. Choose the free official app for your territory, or invoicing software from your Hacienda's register of approved software (*software garante*).
2. Log in with your digital ID.
3. Create each invoice in the app. It adds a TicketBAI code and a QR code, and sends the invoice to Hacienda.

| Mandatory since | 1 July 2024 for professionals | 1 June 2023 | 1 December 2022 |
| Free official app | [Haz tu factura](https://www.batuz.eus/es/haz-tu-factura) | [FakturaBAI](https://www.gipuzkoa.eus/es/web/ogasuna/ticketbai/fakturabai) | [FakturAraba](https://web.araba.eus/es/hacienda/fakturaraba) |
| Approved software | [Register](https://www.batuz.eus/es/registro-de-software) | [List](https://www.gipuzkoa.eus/es/web/ogasuna/ticketbai/listado-software) | [List](https://web.araba.eus/es/hacienda/ticketbai/listado-de-software) |

Software approved in one territory is valid in all three.

### Álava

- Open the app: [FakturAraba](https://ticketbai.araba.eus/tbai/fakturaraba/?idioma=es). Log in with BakQ or a digital certificate.
- It cannot be used for the VAT group scheme at advanced level (*06 Régimen especial grupo de entidades en IVA, nivel avanzado*). It cannot yet issue invoices to public administrations that ask for the Facturae format. Both are listed on the [FakturAraba page](https://web.araba.eus/es/hacienda/fakturaraba).
- Help: the [FakturAraba user guide](https://web.araba.eus/documents/d/araba/fakturaraba-manual-de-la-aplicacion-v1-10-pdf) (PDF).

### Bizkaia

- Open the app: on the [Haz tu factura page](https://www.batuz.eus/es/haz-tu-factura), press the button ACCEDER A "HAZ TU FACTURA" (open Haz tu factura). It opens the Izenpe login, where you use your digital ID.
- You can only issue invoices in your own name. It cannot be used for the VAT group scheme at advanced level (*06 Régimen especial grupo de entidades en IVA, nivel avanzado*). Both limits are listed on the Haz tu factura page.
- Help: phone 946 125 500 for tax questions, 946 083 566 for technical problems.

### Gipuzkoa

- Open the app: [FakturaBAI](https://egoitza.gipuzkoa.eus/WAS/CORP/WATTramiteakWEB/inicio.do?app=FAKTB&idioma=C). Log in with BakQ, the Izenpe mobile app or a digital certificate. You need one, because each invoice is signed electronically.
- It cannot be used for the investment gold scheme (*04*), the VAT group scheme at advanced level (*06*), professional fees you collect on behalf of someone else (*10*), or building work certificates to a public administration with VAT not yet due (*14*). The list is in the "Nota" on the [FakturaBAI page](https://www.gipuzkoa.eus/es/web/ogasuna/ticketbai/fakturabai).
- Help: the [FakturaBAI user manual](https://www.gipuzkoa.eus/documents/2456431/13761128/Manual+FakturaBAI+v.4.+es.pdf/2bda9f8d-3d36-60e5-b4cb-3e6f2ac95af5) (PDF), or call Hacienda on 943 113 000.

## Cost and time

- Cost: none of the three official apps lists a fee.

## Common mistakes

- Using invoicing software that is not on the approved list.
- Assuming the free app covers every case. Each app excludes some special VAT schemes and kinds of invoice. Check the list for your territory under By territory before you start.

## From our experience

We issue our monthly invoice to a client in Ireland with Haz tu factura in Bizkaia. The invoice then appears in our record book without extra work.
