You have the choice to enable an optional restriction that prevents custom discounts from being applied on both the product and bill level in Qashier POS.
Here's the steps to control access and apply restriction on custom discount:
Reach out to our support team to activate this function for you
Once this is activated, refresh your POS by going back to the main page
Each time you give a discount, a terminal PIN will be necessary
If the restriction is applied, you will see a screen to key in the Terminal PIN when you tap on custom discount.
If the Terminal PIN is entered correctly, you will be brought to the % or $ discount screen to key in the discount to be applied to the product or bill
If the Terminal PIN is keyed in wrongly, the screen will show a notification of Invalid PIN and redirect you to the previous page.
