Who it is for

  • Small and medium businesses that want free, open source POS

    The vendor says version 5.0 is free to download from Sourceforge, and its stated aim is to make a commercial-grade open source POS accessible to small and medium businesses.

  • Bars, cafes and restaurants

    Has a restaurant mode with table management, split receipts, kitchen printing and reservations; a case study covers three themed bars and a night club in Warrington, UK.

  • Mixed retail and hospitality venues

    One install can run in retail, restaurant or supermarket mode, so a venue selling both goods and table service can use one system.

  • Technical users and POS resellers

    Source code, developer guides and an API are included in the paid plans; the vendor pitches the Plus plan at tech-savvy users and resellers.

What it does

  • Restaurant mode and table management

    Table view with move table, split receipts, transfer order items and reservations.

  • Kitchen and remote printing

    Sends orders to kitchen printers, and a remote display can show orders in a kitchen, packing area or warehouse.

  • Retail and supermarket modes

    Barcode scanning, weighing scales, units of measure, bundles and variable pricing.

  • Multi-payment and card payments

    Mixed and partial payments, plus integrated card payments in the UK, EU and USA.

  • Stock management

    Stock levels, min/max levels, multi-warehouse and multi-store locations, transfers and loss prevention.

  • Customer accounts

    Customer store cards, credit limits, account sales and settlement, discounts and transaction history.

  • Supplier records

    Tracks supplier details, deliveries, credit limits and transaction history.

  • Employee management

    Access levels, check-in and check-out, breaks and leave, and performance records.

  • Reports and web reports

    Employee, customer, financial, inventory, sales and supplier reports; web reporting runs on WordPress and needs a web host.

  • REST API

    Customer, order and product APIs to connect the POS to e-commerce, ERP or CRM systems such as WooCommerce.

  • Digital receipts

    Provides a digital copy of the receipt to strengthen the brand connection with customers.

  • Web server / browser version

    Runs the full POS on an Android or iOS device or countertop machine through a browser.

  • Multi-terminal and multi-lingual

    Several terminals can share one system, and the interface supports multiple languages.

  • Customisable receipts and scripting

    Editable receipts and tickets, custom buttons and a scripting language.
