Find your fit

Who it is for

A general store or supermarket can use the described simple sale screen for barcode-led checkout. A specialist shop can assess the standard screen's ability to set aside an unfinished order and resume it later. The operator should test both flows on the version it plans to install.

The vendor also addresses restaurants and cafés, including routing products to grouped remote printers. Table and split-receipt functions appear in the v4 checklist, so a hospitality buyer should confirm the chosen release and any extra display or printer component before designing service around them.

The work it supports

Core capabilities

In retail mode, barcode scanning can speed selection of a stocked item. The FAQ describes a simple screen for high-volume checkout and a standard screen for a more considered sale, where a partially completed order can be recalled. Try a mixed basket, correction and return during evaluation.

The vendor describes restaurant and café operation with grouped remote printers for food or drink orders. Test routing a revised order to each intended station, then check what happens when a printer is unavailable. The v4 feature list also names moving tables and splitting receipts; confirm those exact controls in the chosen release.

The v4 checklist lists receipt customization and the choice to print or not print. Create a test receipt with the venue's required tax details and return information, then confirm those settings still work in the selected version and on the selected printer.

Stock management, stock levels, transfers, multiple stores and warehouses appear in the v4 checklist. A shop considering these functions should trace one item from receipt into stock, through a sale, and into a count or transfer; check how the current release handles corrections and synchronization.

The v4 list includes sales, inventory and financial report areas. Compare a sample day's register activity with those reports before relying on them for reconciliation or replenishment decisions, especially if several terminals or locations are involved.

The FAQ says formatting can pick up currency, number and date settings from the operating system, while tax rules can be configured. Test local tax combinations and receipts with an accountant; those settings alone do not establish tax or fiscal compliance in a country.

Understand the offer

Pricing and getting started

The homepage offers community version 5.0 as a free GNU GPL3 download. The FAQ distinguishes that public code from newer subscriber releases and support services. A business can start with the community route, but should budget its own installation, device maintenance and help if it does not subscribe.

Support membership gives access to newer releases plus listed benefits such as bug fixes, feature upgrades and a private forum. The current subscriber changelog lists 5.5.1 as a September 2026 patch. Compare the chosen community and subscriber builds directly before assuming they contain the same features or fixes.

Integrated card payments are marketed for the UK, EU and USA. The 5.5.1 notes specifically say US subscribers can enable a partner integration. Ask which release, payment partner, terminal, contract and fees apply to the venue rather than treating card acceptance as automatic with the free download.

The homepage lists Windows, Linux, Apple and browser use, but its displayed Windows and Mac version examples are dated. Obtain current install requirements for each proposed device. Non-English translations are community supplied and may fall back to English, so test the staff language before purchase or rollout.

Look a little closer

Before you choose

Choose a release first, then walk a complete transaction through item selection, an edited order, tax, payment, receipt, stock change and end-of-day report. The public v4 feature list is a useful test plan but should not be read as a current v5.0 or 5.5.1 entitlement table.

For a restaurant, test kitchen-printer routing and table handling with the actual equipment. For a multi-site shop, test stock transfer and report visibility. The sales and inventory screens described by the vendor are only useful if they stay consistent through real corrections and device failures.

Confirm the support path and payment arrangement before go-live. The public community build and subscriber build move at different cadences, integrated card payments have regional and partner conditions, and a translation or operating-system issue may need testing on the venue's hardware.
