Core is flexible regarding applying discounts to bill amounts before and after taxes. By default, it applies a discount after the taxes.
Here are the steps to do so:
- Open the Invoices screen and create an invoice. Check Core Help Center for details on creating invoices.
- Apply a discount to a billing record by entering an amount, which reduces the Net Bill amount after taxes have been added. It does not reduce the tax amount of either services or expenses.
- Process the invoice as usual.
However, if you want to apply a discount to the bill amount before taxes, go to the Global Settings > Billing screen and select 'Apply discount to pre-tax amount'.
