Desktop POS Overview
Desktop POS is a native point-of-sale application for Windows, macOS, and Linux that issues fiscally signed receipts from a local SDC — a full-featured till for businesses that want an installed app rather than a browser.
What is Desktop POS?
Desktop POS is an installed desktop application that handles the complete till workflow: sell, fiscalize, print, and report — all from a local database that keeps working whether or not you have an internet connection. When you run multiple devices across one or more locations, the optional Backoffice web application keeps everything in sync.

Key Features
Native app — runs on Windows, macOS, and Linux; no browser required
Offline-first — a local database means the till keeps selling even without an internet connection
Direct hardware control — barcode scanner, thermal and A4 printer, cash drawer, customer display, and card terminal are all managed directly by the application
Shifts & cash management — open/close shifts, record cash in/out, and reconcile at end of day
Products, inventory & purchasing — manage the catalog, track stock, and create purchase orders
Promotions — rule-based discounts that apply automatically at the till
Restaurant and hotel modules — available where licensed (covered in separate guides)
Multi-device sync — connect several tills to the Backoffice for a central catalog, consolidated reports, and device management
Desktop POS vs. Web Invoicing
Desktop POS | ||
|---|---|---|
Delivery | Installed native app | Browser-based cloud service |
Devices | Windows, macOS, Linux desktop | Any device with a modern browser |
SDC | Local/networked SDC with smart card + PIN | V-SDC using a digital certificate (PFX file) |
Peripherals | Direct — the app controls printers, cash drawer, scanner, and terminal | OS-mediated — peripherals interact via the operating system |
Offline | Full local database; sells without internet | Requires connectivity to the V-SDC and cloud |
Multi-device | Backoffice sync — central catalog, reports, and device management | Centralized cloud — all devices share the same portal |
Who Is It For?
Desktop POS is a good fit if you:
Want a fully installed till rather than a browser tab
Need offline resilience — the database is local and the till never stops because of a network outage
Require direct control of hardware peripherals (thermal printer, cash drawer, customer display, card terminal)
Run more than one till and want central management through the Backoffice
Technical Specifications
POS Type
Desktop POS is a computerized Point of Sale system (POS) delivered as a native desktop application. It is not a cloud or browser-based product — it is software installed and run locally on each device.
Installation
Desktop POS is downloaded and installed locally on each device. There is no browser or internet connection required to run the till once installed.
Supported Operating Systems
Operating System | Supported |
|---|---|
Windows | Yes |
macOS | Yes |
Linux | Yes |
Android | No |
iOS | No |
Supported SDC Types
Desktop POS communicates with a local or networked SDC using a smart card and PIN. The SDC must be physically accessible on the local network.
SDC Type | Supported |
|---|---|
Local/networked SDC with smart card + PIN | Yes |
Connection to SDC
Desktop POS connects to the SDC over the local network using the SDC host and port configured in Settings → Connection. The default address is localhost:8888.
Communication uses the HTTP protocol with the E-SDC.
Note: If the SDC is offline, the smart card is absent, or the PIN has not been verified, sales cannot be fiscalized.
Peripheral Devices
Desktop POS directly interfaces with the following peripheral hardware:
Barcode scanner — scans products at the till
Thermal printer — 58 mm or 80 mm ESC/POS receipt printing
A4 printer — full-page invoice printing
Cash drawer — kicks automatically after a fiscalized sale
Customer display — shows line totals to the customer
Card terminal — integrated card payment
All peripheral devices are configured in Settings → Hardware. These peripherals assist the operator but do not interfere with the standard fiscal POS operations — selling, fiscal signing, SDC communication, and reporting continue to function exactly as documented regardless of which peripherals are attached to the device.
