There are two main ways to add discounts to a purchase order, depending on the :
Enter a discount for the entire purchase order (Settings > "Default Discount %" field)
Enter a discount for specific variants (enabling the "Discount %" column)
This article discusses both methods.
Note that if your purchase order already exists, you will need to click "Edit" in order to be able to apply the discounts.
Note: Discounts cannot be pushed to a QuickBooks Commerce connection because that platform does not support discounts on a purchase order.
Discounting an entire purchase order
While editing your purchase order, click "Settings" in the top right-hand corner of your purchase order, then scroll down to the "Vendor" section to find the "Default discounts %" field.
Enter the percentage discount into the field, then click out of the Settings menu. You will get a popup asking you to confirm the discount.
Click "Update" to apply the discount to all rows, then save changes to your purchase order.
Discounting specific rows
To create a discount for an individual variant, enter the discount percentage into the "Discount %" column for that variant's row.
If you don't see this field, enable the Discount % column by clicking on the gear icon on the right side of your screen.
Once you've added the discount, save changes to the purchase order.
