Get Verifactu-compliant without fighting your software.
Gestusser invoices, collects and files your taxes for you — from a single panel, in the cloud, ready for the Spanish tax authority from day one.
No installations · No lock-in · Verifactu and FacturaE compatible
You're running your business with spreadsheets, emails and scattered folders. And now the tax authority requires Verifactu.
Every hour reconciling invoices is an hour you don't spend on your business. The new anti-fraud rules require your software to sign, chain and electronically report every invoice. Not adapting isn't an option.
If your current tool doesn't comply, you face penalties and a forced rushed migration.
Gestusser already complies. You focus on what you do best.
Everything you need. Nothing you don't.
