VMS Compliance Documentation

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
