# 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
