From 2027 every invoice a Spanish business issues must come from a system that meets Verifactu (Royal Decree 1007/2023): a chained, hashed record, a QR code and, in VERI*FACTU mode, immediate sending to the Spanish Tax Agency (AEAT). Set up in five minutes: enter your NIF, upload your digital certificate and send a test invoice. From then on every paid order gets its invoice or ticket, sent to AEAT with your certificate, and you see AEAT's answer on the order. If anything fails, you are told.

• Simplified or full invoice with QR code for every paid order
• Record sent to AEAT at once, with its answer shown on the order
• Corrective invoice (rectificativa) on every refund, automatically

Polish VAT taxpayers issue invoices to business buyers in KSeF, the national e-invoicing system. To start: enter your NIP and company name, create a token in the Ministry of Finance's KSeF app and paste it into the app. From then on every paid order with the buyer's NIP becomes a KSeF invoice, its KSeF number and state shown on the order. Refunds become corrective invoices. Consumer invoices are optional.

• A KSeF invoice for every paid order with the buyer's NIP
• KSeF number and state on the order; a rejection shown at once
• A corrective invoice for every refund, automatically
• PDF with the KSeF number and QR code emailed to the buyer
• Consumer invoices optional, switched on in one click
