Wix Invoices Request: Applying a Discount to a Single Product or Service
Collecting votes
Currently, when you add a discount to an invoice, it applies to all products or services added to the invoice. It is not possible to add a discount to only one product or service on an invoice.
Workaround:
You can manually change the cost of a product or service when adding it to the invoice.
We are always working to update and improve our products, and your feedback is hugely appreciated.
