Can I charge a discount on the sales invoice?

Unfortunately, it is not possible in Yuki to calculate a discount percentage per item or on the total amount of a sales invoice.

However, you can apply a price discount per item. To do this, you need to create a sales item (discount) that includes the discount as a negative amount. You then add this sales item as an invoice line to the relevant sales invoice.

You also have the option of recording a price agreement with a sales item or a customer. This makes it possible to use a certain price of a sales item for a specific customer.

For a detailed description of creating sales items, see article Create sales item.
