Facturae is the Spanish standard for electronic invoicing — mandatory for B2G (public-sector buyers) and progressively required for B2B under Crea y Crece. OMB Cloud generates and signs Facturae 3.2.x natively.
One-time setup
- Get a XAdES signing certificate from FNMT or another approved AC.
- In
/app/master-billing→ your ES entity → "Facturae settings", upload the certificate and enter the key password. - Set defaults: CIF/NIF, address, IRPF retention rate (if applicable).
The issuance flow
When you issue: OMB Cloud (1) generates Facturae 3.2.x XML from your line items; (2) signs with XAdES-BES; (3) optionally submits to FACe (the public B2G platform) if the receiver is a public entity; (4) generates a printable PDF; (5) emails both to the client.
VAT scenarios
Spanish IVA is 21% standard. The system handles reduced rates (10%, 4%), VAT exempt sales (with the correct exemption code), and reverse-charge VAT (inversion del sujeto pasivo) for intra-EU and certain domestic operations. Set the line-item VAT scenario in the Catalog.
IRPF retentions
For self-employed professionals receiving invoices, IRPF retention applies. Configure the rate (typically 15% or 7% for new freelancers) on the client record. The system applies it automatically on each invoice issued to that client.
FACe submission
If the client is a Spanish public administration, enable "Submit to FACe" on the invoice. OMB Cloud handles the submission via the FACe webservice and tracks delivery and acceptance status.
Tips
- The Facturae spec changes occasionally; OMB Cloud auto-updates to the current version. No manual XSD update needed.
- Test with a low-value internal invoice before issuing to your first public-sector client.
