1. Install

Open the downloaded file and follow the steps. If Windows says "Windows protected your PC", press "More info" and then "Run anyway".

3. Stay up to date

The till checks for new versions by itself. When one is ready you will see "Update available" on the sign-in screen and in About (the "i" button). Your sales and settings are kept.

What's new

The version and build number are shown at the bottom of the till's sign-in screen, so you can check which one you have.

  1. Version 1.0.2 (build 4)

    November 12, 2026

    Offline, payment and shift fixes

    • Sales made while offline keep retrying and reach the server on their own when the connection is back.
    • Split payments show the change to give back, and cash sales and expected cash no longer include that change.
    • A shift closed while offline is sent to the server when the next shift opens, with the confirmed expected cash and variance.
    • Quick card payments (F7) ask you to confirm the card was approved.
    • Receipt printing starts with the customer and kitchen copies instead of every copy.
    • Switch employee from the top bar without signing the till out. The till can't be removed while sales are still waiting to sync.

  2. Version 1.0.1 (build 3)

    November 12, 2026

    Sign-in and refund fixes

    • Fixes "Tenant not set" and an empty menu after signing the device out and activating it again.
    • Refunds work again, show what was already refunded on each line, and never refund more than is left.
    • Saved settings on Windows are more reliable when the till is busy or restarts.
    • A slimmer top bar gives the product search much more room.

  3. Version 1.0.0 (build 2)

    First public release

    • Tells you when a new version is ready, with a one-click download (About & updates).
    • Tax is rounded to the nearest cent, the same way the portal and online store do it.
    • Receipt numbers on the till now match the order numbers in the merchant portal.
    • The Cash button asks how much the customer handed over and shows the change to give back.
    • Refunds, voids, cash-outs and big discounts can ask for a manager's PIN.
    • If a shift is closed from the portal or another till, this till notices and asks you to open a new one.
    • Kitchen display and online-order alerts now disappear on their own after a few seconds.
