This document explains how our POS system works with the fiscal system (SDC) in a simple way.

1. POS must be connected to SDC

Our POS system cannot create or print an invoice unless it is connected to the SDC.

  • If there is no connection → no invoice can be made
  • This ensures all invoices are properly recorded by the tax system

2. No changes to SDC response

When the SDC sends back invoice information, the POS system:

  • Does not remove anything
  • Does not change anything

What the SDC sends is exactly what appears on the invoice.

3. No sales without fiscal invoice

Every sale must have a fiscal invoice.

  • You cannot record a sale without generating an invoice
  • This ensures all sales are officially tracked

4. Invoice header must be complete

The top part of the invoice (issuer details):

  • Includes all information returned by the SDC
  • Nothing is missing or hidden

This guarantees correct business identification on every invoice.

5. External printer support

The POS system:

  • Supports an external printer
  • Can send invoices to a connected printer device

6. Built-in printing capability

The POS system also:

  • Has printing as part of the system itself
  • Can print invoices directly without needing special setup

Summary

  • No SDC → No invoice
  • No invoice → No sale
  • No changes allowed to SDC data
  • All invoice details must be complete
  • Printing is fully supported
