Offline vs cloud
Why choose offline shop software?
Cloud POS suits shops that want to check sales from anywhere. RMS suits shops that want to keep selling through internet outages, own their records and stop paying every month.
| RMS (offline) | Typical cloud POS | |
|---|---|---|
| Works when the internet is down | Yes, always | Usually limited or not at all |
| Where your records live | On your own computer | On the provider's servers |
| How you pay | Yearly from USD 39, or once for life | Every month |
| If you stop paying | Read-only: view, print, back up | Access usually ends |
| Open your shop from home | No (one computer per licence) | Yes, from a browser or app |
| Government e-invoicing / fiscal reporting | Not included | Some providers include it |

Questions shop owners ask
What is RMS?
RMS — Retail Management System is offline point of sale (POS) and shop management software for independent shops anywhere in the world. It runs on the shop's own computer and works without internet. RMS sets itself up for 12 kinds of shop: oil change, tyre shop, auto workshop, car wash, spare parts, bike shop, general store (grocery), departmental store, clothing, mobile & electronics, hardware and other retail.
Does RMS work without internet?
Selling, printing, reports, backups and licence activation all work without internet. The shop's records stay on its own computer. Internet is needed once, at setup, to register the business. During a power cut, keep the computer on a UPS and keep selling.
How much does RMS cost?
RMS Basic costs USD 39 a year or USD 99 once (lifetime), for 2 users. RMS Pro costs USD 79 a year or USD 199 once (lifetime), for unlimited users. There is no monthly fee. Every installation starts with a free 14-day trial with all Pro features. No card is needed.
What language is the software in?
The app's screens, bills and reports are in English, in plain words a counter cashier understands.
Which computers does it run on?
RMS runs on Windows 10/11 (64-bit), Windows 10 (32-bit), macOS and Linux (Ubuntu/Debian .deb and AppImage). The Windows installer works without internet.
Which currencies does RMS support?
RMS works in your own currency: choose the currency symbol, its position, 0 or 2 decimals, the number grouping (1,234.50 or 1.234,50), the date format and the time zone. Country presets fill these in at setup.
Can I sell in litres, kilograms or cartons?
Products can be stocked, bought and sold in different units — pieces, litres, millilitres, US or imperial gallons, kilograms, pounds, metres, feet, dozens, packs, cartons and more — with conversions such as 1 carton = 24 bottles. Quantities like 3.5 L or 1.25 kg are allowed where the unit permits.
Is RMS connected to a government tax system?
RMS prints tax invoices with your own tax name (VAT, GST or sales tax), rate and registration numbers, but it is not connected to any government e-invoicing or fiscal reporting system. Businesses that must report each sale to a tax authority in real time need a certified system.
What happens to my data if I stop paying?
If the trial or a licence ends, RMS becomes read-only: the shop can still view, print, export and back up its records. Data is never locked away.
Can I try it before buying?
Every installation starts with a free 14-day trial with all Pro features. No card is needed. Download it, choose your kind of shop and start selling in about three minutes.
