Migration from traditional systems (Excel/PDF/paper) and training for financial and administrative teams.

Additional Information

The “Create and Grow Law” (Law 18/2022) will require all companies and self-employed professionals engaging in B2B transactions to issue and receive electronic invoices starting in 2026, with different adaptation periods: 1 year for billing > over €8M, up to 2 years for others. From July 2025 / January 2026, the use of certified systems compatible with Verifactuwill be mandatory to ensure integrity, traceability, and transparency. The regulation requires electronic invoices to be stored for at least four years and to report their status (accepted, rejected, paid), with penalties of up to €10,000 for non-compliance . At Onizea, we see this regulation as an opportunity for digitalization and professionalization. We provide a flexible, scalable, and legally sound solution, especially useful for businesses still using manual processes. Odoo ERP is our platform of choice: from full invoice management to advanced automation, it’s the ideal tool to digitalize your admin department. We meet all the requirements of Annex IV of the Digital Kit Program, ensuring technically sound and trustworthy execution. With Onizea InvoiceHub, the shift to electronic invoicing isn’t just mandatory — it’s a strategic digital leap.
