What actually changed in Spain?
Nothing terrifying. Here's what it means in plain English.
The good news: Your day-to-day invoicing feels the same. The difference is what happens behind the scenes in the software. BillBee handles all of it automatically.
Why is there a QR code on invoices?
The QR code acts like a digital ID tag for the invoice. It's not decoration — it contains verification information that makes the invoice tamper-proof.
Advanced technical details
The QR encodes a SHA-256 hash that links each invoice to the previous one. This makes it cryptographically impossible to alter records without detection. BillBee generates this automatically on every issued invoice.
