If you want to apply a quick discount on an order, you can do so right before issuing the tax receipt to the customer.

You will need to select the icon in the form of a 3-point circle and from there select Payment Options.

From here you will select Quick Discount.

You can choose to offer a quick discount from the displayed options or enter a value manually.

You can change the discount from a percentage to a value discount, by clicking on RON or % from the top right.

Click on Subtotal and the discount will be applied to the order.

All you have to do is choose the payment method by which the bill was paid.

Warning: To authorize this discount, it will be necessary to enter the PIN of a POS Manager, if there is one set in the administration account. For more details on this option, access this link.
