Comparison
BillBee vs Excel invoicing
Excel is familiar and flexible. But it is not a protected invoicing system — and that is becoming a problem in Spain.
| Area | Excel / Word invoices | BillBee |
|---|---|---|
| Invoice numbering | Easy to duplicate or skip | ✅ Guided, clean sequence |
| Editing old invoices | Easy to silently change | ✅ Issued invoices protected |
| Corrections | Usually manual and messy | ✅ Guided correction flow |
| IVA / IRPF help | You need to know it all | ✅ Plain-English help built in |
| Gestor export | Files scattered everywhere | ✅ Clean export pack |
| Veri*Factu preparation | Not designed for it | ✅ Built around SIF / Veri*Factu |
| Audit trail | Weak or manual | ✅ Structured history |
| Confidence level | "I hope this is okay" | "I know what this step means" |
2027 deadline reminder
Excel invoices are unlikely to meet Veri*Factu requirements. Companies must be ready by 1 January 2027. Autónomos by 1 July 2027. Starting the migration now avoids the last-minute rush.
