Frequently asked questions
Does it comply with Verifactu and TicketBAI?
Yes. Certified by the tax authority. The POS meets both regulations automatically on every sale.
How long is data kept?
Four years, tamper-proof. That's the period Spanish regulations require for fiscal records.
What if I need to void a sale?
You void or return with a reason. It's logged: who did it, when and why. That traceability is exactly what the tax authority looks for in an inspection.
Do I need to buy a separate module for e-invoicing?
No. E-invoicing comes integrated with the POS. No additional licence, no extra vendor.
How does cash reconciliation work?
Open with a starting float, log deposits and withdrawals during the shift, and close with automatic balancing. The system calculates the difference between expected and actual.
Does it export for my accountant in SII or modelo 303 format?
TODO — pending confirmation with CS on which standard export formats the system supports today.
Is sequential numbering guaranteed?
Yes. The system generates sequential numbering automatically. No gaps, no duplicates.
Can't I just use a spreadsheet?
No. Regulations require a certified invoicing system, guaranteed sequential numbering and tamper-proof data. A spreadsheet meets none of the three.
