You can make Qashier POS ask for the Terminal PIN before staff add or edit a custom discount, so only people who know the PIN can give ad-hoc discounts. The setting covers custom discounts on the whole bill and on single items.
Applies to
Markets: all markets.
Product: set up in QashierHQ; applies on Qashier POS.
Access: a QashierHQ user with access to Settings.
Before you start
Your store must have a Terminal PIN. Set it in QashierHQ under Settings > Store > Basic Settings > Terminal PIN. If no Terminal PIN is set, Qashier POS does not ask for one, even when this setting is on. See How to View or Change Your Terminal PIN in QashierHQ.
Turn on the PIN requirement in QashierHQ
Log in to QashierHQ and click the Settings (gear) icon at the top right.
Under Store, open Additional Settings and select your store.
In the Discount Management section, tick Require Terminal Pin to use discount funtion in POS (this is how the label is spelled on screen). The setting saves automatically.
On Qashier POS, go back to the main page so the terminal picks up the new setting.
If you do not see Additional Settings, for example on an account that manages several businesses, contact Qashier support to turn it on for you.
What staff see on Qashier POS
Staff tap Custom Discount on the bill or on an item, or tap the pencil icon to edit a custom discount.
The Terminal PIN window opens: "Please enter the terminal PIN".
If the PIN is correct, staff tap Confirm and the custom discount screen opens, where they enter a % or amount discount.
If the PIN is wrong, the POS shows Invalid PIN. and the custom discount screen does not open. Tap Custom Discount again to retry.
What the PIN does not cover:
Preset discounts created in QashierHQ can still be applied without a PIN. To control which discounts staff can give, use preset discounts. See How to Create a Preset Discount in QashierHQ.
For combo items, the POS asks for the Manager PIN instead of the Terminal PIN. See How to Change the Manager PIN in QashierHQ.
