What's included FactuSync
Everything you need to invoice in line with VeriFactu. No monthly fees, no reliance on the internet.
VeriFactu compliant
Create invoices with every field required by RD 1007/2023. The record is sent to the AEAT in real time with instant confirmation.
XAdES electronic signature
Every invoice is digitally signed with XAdES. The hash chain guarantees integrity and immutability against any later change.
No connection required
Works offline. Your data stays on your computer — never on third-party servers or locked into cloud subscriptions.
Quarterly reports
Automatically calculates form 303 and produces the 390 summary straight from the invoices you have already recorded.
Easy installation
Installer for Windows and macOS. No browser, no server setup, no technical knowledge needed.
Encrypted backup
Encrypted backup stored locally and in the cloud. Your data is accessible only with your password, never exposed.
Four steps to your first VeriFactu invoice
From download to AEAT registration in under 10 minutes. No account, no card, no commitment.
Install in minutes
Download the installer, run it on Windows 10 or 11 and launch FactuSync. No account or credit card needed.
Set up your tax details
Enter your tax ID (NIF), company name and contact details just once. FactuSync applies them to every invoice you issue.
Issue the invoice
Add the customer, line items and taxes. The app works out VAT and IRPF and produces the signed PDF in under 3 seconds.
Automatic AEAT registration
The VeriFactu submission happens automatically. You get instant confirmation and the PDF is saved to your history.
Technology that backs every invoice
FactuSync implements the technical standards the AEAT requires for verified invoicing systems.
The XAdES signature guarantees the integrity of every document. A hash chain links each invoice to the previous one, making any retroactive change impossible.
The communication channel with the AEAT uses TLS 1.3 and an electronic seal certificate. Your customers' data never leaves your computer without your permission.
