Tempo began as an internal solution developed by Strong Abogados more than 15 years ago to simplify accounting and compliance for international clients in Spain. At the time, there were no English-language systems adapted to Spanish tax, payroll, and reporting rules. Over the years, it evolved into a complete online platform that automates compliance and connects all core processes in one place.

All filings are managed directly by our legal and accounting professionals through Tempo. The platform centralizes your data, while our team prepares, reviews, and submits every form on your behalf. This ensures every filing meets Spanish legal and technical standards with full accuracy. If you wish to use Tempo only for invoicing compliance, that is also okay, you can create your invoices in Tempo and then export all the data for accounting or tax filing. This can also be done for Xero/Quickbooks, where you create an invoice, we make it compliant, and then we can do your accounting and tax filing, or you can export from Xero/Quickbooks and solve compliance on your own.

VeriFactu is Spain’s new electronic invoicing and traceability system, created under Royal Decree 1007/2023. It requires all invoices to include QR codes, hash chaining, and event logs to prevent tampering.

• ⬤ Companies: mandatory from January 1st, 2026
• ⬤ Freelancers: mandatory from July 1st, 2026

Tempo is already VeriFactu-ready and fully aligned with the structure of the RRSIF (Real Decreto del Sistema Informático de Facturación).

Tempo follows the exact technical and legal standards defined in the RRSIF regulation. A formal declaration of compliance (“declaración responsable”) is signed by each client before starting, confirming that they use certified, VeriFactu-compliant software. This declaration is what legally authorizes the issuance of compliant invoices in Spain.

Tempo integrates through exclusive API connections that automatically import invoices and accounting data from QuickBooks and Xero. It converts them into Spanish-compliant formats, adding the required QR code, hash identifier, and event log for VeriFactu. Invoices can then be sent back to QuickBooks or Xero, keeping your records complete and compliant without duplication.
