Migrate from Anfix to Cofactu
without losing a single invoice
Anfix is built for accounting firms; many individual self-employed users find it too complex and outdated in UX. If you want a modern cloud tool with real VeriFactu and bank reconciliation included, bring your data over with Anfix's Excel export.

What shouldn't be lost Moving the history doesn't mean
Moving the history doesn't mean
breaking its context.
The move keeps what you need to consult the past and separates new invoices so you can review before continuing.

02Continuity register · 3 checks Zero invoicing downtime Keep invoicing in Anfix while Cofactu imports in parallel. When you're ready, cancel the subscription — your data in Cofactu stays right where it is. 
03Continuity register · 3 checks No lock-in If you ever want to leave, export data per module (clients, invoices, expenses, PDF + XML records, VAT ledger) and request a complete account copy. We don't block the exit. One documented path, with a review before importing.
Cofactu does not import through the Anfix API. The guide starts from the exported file and a prior review of its contents.

Export from Anfix
- 2 min · File
Export from Anfix
Anfix → Invoicing → Lists → Export to Excel. Repeat for Contacts. Anfix lets you export the full VAT ledger (Input/Output VAT). If you're an accounting firm with multiple clients, export each one separately — Cofactu imports them into separate organizations under your accounting-firm account.
- 1 min · File
Upload the files to Cofactu
Create your free account and, in Invoices, click Import and upload the file. Do the same for contacts from Clients. Cofactu suggests which field each column goes to (if one doesn't fit, Lucía helps you map it) and you review it. Before confirming you see a preview of what will be imported.
- 2 min · File
Confirm + go
Review the preview with N invoices + M clients and hit Import. Done. Invoices keep their original Anfix numbering and arrive as historical, without being sent to AEAT. The Cofactu VeriFactu hash chain starts clean with your first new invoice.

can already do the work.
These are the capabilities that stay connected after bringing the history over from Anfix.
| 01 | Modern UX, not a decade old | Cofactu is redesigned for 2026: command palette, keyboard shortcuts, responsive dashboard, dark mode coming soon. Anfix carries legacy UX built for advanced accounting-firm use — solo self-employed users feel lost in nested menus. |
|---|---|---|
| 02 | Real VeriFactu with an error catalog | Cofactu files with AEAT from day 1 with an official CSV. AEAT error catalog explained (1xxx/4xxx/5xxx), automatic broken-chain detection (4171), 1-click repair. Anfix has it but less polished. |
| 03 | Bank reconciliation on every paid plan | Statement in Norma 43, CSV or Excel from any bank, auto-reconciliation with invoices and the 572 entry on confirmation. In Anfix, banking depends on the plan. |
| 04 | AEAT forms prepared by channel | Cofactu calculates all seven forms and generates the official file for 303, 111, 115, 190, 347 and 349; form 130 is prepared as a draft. You or your accounting firm file them in the AEAT online office. |

The history arrives. The next tax forms
are born from your new data.
Cofactu aggregates new invoicing, expenses and withholdings to prepare the supported tax forms from the same system.
Before migrating from Anfix.
Answers on timing, history, numbering and continuity before you confirm the move.
Ask about my case →Are my invoices already sent to AEAT from Anfix re-submitted?
No. Every imported invoice arrives as historical (accepted) and Cofactu never sends it to AEAT, so there are no duplicates. It doesn't carry the AEAT CSV: keep the receipt in your previous software. Cofactu's VeriFactu hash chain starts clean with your first NEW invoice.
Do I lose Anfix's change/audit history?
Anfix's internal logs stay in Anfix — our importer doesn't extract them. But from the moment of import, Cofactu keeps its own immutable audit log with a hash chain.
Does it work with any Anfix plan?
Yes. Cofactu doesn't use Anfix's API: it imports the Excel export, which is available on every plan.
How long does it take with 500 invoices?
It depends on the file size, but there's no sync to wait for: you upload the export and, before confirming, you see a preview with exactly what will be imported.
I'm an accounting firm with several clients in Anfix, how do I migrate?
The Cofactu Accounting Firm plan (€89) covers up to 50 clients with native multi-tenancy, and Accounting Firm Pro (€199) unlimited clients. You import each client as a separate organization under your accounting-firm account. Bulk XLSX import lets you upload several at once.
What about my tax forms filed from Anfix?
The filing data stays in Anfix; Cofactu imports the invoices, expenses, and payroll that SUPPORT those forms. From there, Cofactu aggregates the data and generates the official files currently available for manual filing.
Can I also migrate recurring invoices and quotes?
No. Recurring invoices and quotes aren't imported from the export: you set the recurring invoices up again in Cofactu, which has them too, and recreate any quotes that are still open.
