If you want to give a discount, you can do that directly in selling. A click on the pencil symbol opens a processing window.
Here you have the option of either assigning a certain percentage or changing the setting to Euro, so that you can determine an individual amount. Either you choose from the given percentages or euro amounts, or you manually enter your desired amount (e.g. 17%, €11, etc.).
You always have to enter a reason. In addition you can edit the validity, the remaining sessions and which open sessions from the past get deducted from the new product.
Click on 'Save' to confirm your entries and continue the selling
