You can include a discount on invoices as either a percentage or a set dollar amount and Wave will automatically reduce the total of the invoice based on the discount you enter
Include a discount on your Wave Invoice
Click Sales > Invoices
Click Create an invoice on the top right or select an existing invoice and click Edit Invoice
Below the subtotal select Add discount
From the dropdown menu select $ to enter a dollar amount or % to enter a percentage value
Enter the dollar amount or percentage of the subtotal
A line labelled Discount appears below the subtotal, reducing the total of the invoice before tax is calculated. You can only enter one discount per invoice.
When you apply a discount to an invoice, Wave takes care of the accounting for you!
The first time you approve an invoice with a discount, Wave will create an account called Sales Discounts. This account is located in your Chart of Accounts under the Income tab.
Discounts appear as negative amounts on your Profit & Loss Report because they reduce your income.
