Depending on your Desktop subscription, you can use advanced pricing, or you can create a discount line item to apply to your invoices.
For an Enterprise subscription, you can use the advanced pricing option, which will allow you to create rules that reflect changes to the prices of items. You can also offer quantity discounts, like you mentioned above, for 30 or more items in your inventory.
If you have a Pro/ Premier account, you can create a discount line item for the invoices. This will allow the discount to show up on the customer's invoices. The steps below will show you how:
- Navigate to the Lists menu and pick Item Lists.
- In the window, select Item and New.
- Choose the type of item you want to create and fill in the item fields.
- (optional) Press Custom Fields to add customized fields.
- Hit Save.
Now you have a discount to apply to your invoices. You may find this article helpful in the Pro/Premier process: Add, edit, and delete items.
