From the AEAT app to Cofactu
once it stops being enough
The AEAT's free VERI*FACTU app works perfectly well for minimal volumes — we mean that sincerely. But its own official listing documents that it doesn't allow exporting records to continue on other software. This guide explains the honest transition: your invoices stay with the AEAT with full legal validity, your series continues, and your new history starts on Cofactu.

02Continuity register · 3 checks Guaranteed series continuity You set up the series to continue where you left off (2026-0015 after 2026-0014). Correlativity intact, a new VeriFactu chain starting clean — the standard procedure the regulation anticipates when changing invoicing software. 
03Continuity register · 3 checks Decide at your own pace (and go back if you want) 30 days free to see if the SME management layer is worth €39/month to you. If you decide it's not — because your volume is still minimal — go back to the AEAT app at no cost. And with Cofactu you do get to take your data with you, as a ZIP export. One documented path, with a review before importing.
The AEAT application does not let you export its records to another system. The transition documents the last series number and keeps the history on the AEAT website.

Don't export anything — you can't (and that's fine)
The AEAT's official listing documents it: records can't be exported to another SIF. Your issued invoices remain viewable in the AEAT's online portal with full legal validity — Hacienda already has them, which is what matters. There's no need to re-issue them, duplicate them, or 'rescue' them. The only thing you need to note down: the last number of each series you used.

Add your clients to Cofactu
Create your free account and add your regular clients (or upload them via CSV if there are many). In the AEAT app you typed the recipient into each invoice. In Cofactu you add them once — with NIF validation included — and it auto-fills forever after. If you have just a few regular clients, this takes minutes.

Set up your series to continue the numbering
Settings → Series → enter the last number issued in the AEAT app. If your last invoice was 2026-0014, Cofactu issues 2026-0015. The regulation requires correlativity within the series, not that the whole history live in the same software. Cofactu's VeriFactu chain starts fresh with that first invoice, exactly as RD 1007/2023 anticipates when changing SIF.

Issue your first invoice with real management behind it
Same VeriFactu validity you had — plus payments, recurring invoices, tax forms, and reconciliation. If half your invoices go to the same client every month, turn it into a recurring invoice and forget about it. Mark payments, reconcile against your bank statement, and file your quarterly VAT return (Modelo 303) from the same place where you invoice.

The switch ends when the new system
can already do the work.
These are the capabilities that stay connected when you continue your operations from the AEAT application.
| 01 | Payments under control | The AEAT app doesn't flag whether an invoice is paid, pending, or overdue — that tracking happens in a separate spreadsheet. In Cofactu every invoice has a payment status, due dates, reminders, and automatic reconciliation against your bank statement. |
|---|---|---|
| 02 | Recurring invoices that issue themselves | A monthly fee to the same client becomes a recurring template that generates and sends itself, with its own VeriFactu record. In the official app every invoice is created by hand, one by one, authenticating with Cl@ve or a certificate each time. |
| 03 | Tax forms built from your own data | The quarterly VAT return (303), the 130, or the 111 are calculated from your actual invoices and expenses in the same app: the 303 and the 111 come out as official files for the AEAT website, and the 130 as a draft to complete there. With the free app, invoicing and filing are separate worlds: you (or your accounting firm) put the forms together on the side. |
| 04 | Room to grow, no ceiling | Counter tickets (simplified invoices the official app doesn't issue), inventory, quotes, expenses with OCR, payroll, accounting all the way to the balance sheet. The day your business grows, the software is already there — no switching systems again. |

Answers on timing, history, numbering and continuity before you confirm the move.
Ask about my case →Is it really true I can't export my invoices from the AEAT app?
No, you can't — and we're not the ones saying it, it's documented in the AEAT's own official listing: 'It is not possible to export records to continue invoicing on another invoicing software system.' It's a known design limitation. The good news: you don't need to export them, because they're already on record with the AEAT with full legal validity.
Do I have to re-issue or duplicate my old invoices?
No. Re-issuing them would be incorrect (you'd be duplicating income). They stay where they are, viewable in the AEAT's portal. On Cofactu you only need to continue your series numbering and, if you want your history at hand for reference, save the PDFs you downloaded at the time.
Is it legal to switch software mid-year?
Yes, completely. The VeriFactu regulation (RD 1007/2023) anticipates a change of SIF: it requires correlativity within each series and that each system keep its own chain of records. Continuing the series on the new software and starting a clean chain is the standard procedure.
What if my volume is still minimal? Is it worth it for me?
Maybe not — and we'd rather tell you upfront: if you issue 2-3 invoices a month to regular clients, with no recurring invoices, no tickets, and no need to track payments, the AEAT's free app is a perfectly reasonable choice. Cofactu pays off once manual management starts costing you hours: recurring invoices, payments, tax forms, banking.
How long does it take to get up and running?
Less time than it takes to create an invoice in the AEAT app with Cl@ve: account signup (2 min), regular clients added (5-10 min), series configured (1 min), and your first invoice issued with a VeriFactu record. All in one sitting.
Can my accounting firm access my data?
Yes — invite your accounting firm with an accountant role and they can see your invoices, expenses, and tax forms without asking you for anything by email. In the AEAT app, third-party access goes through formal power-of-attorney procedures (IZ862/IZ863) and there's no multi-client panel for the firm.
