Discounts can be applied to items while Generating an Invoice, and to Existing Invoices. See below for the steps on how to accomplish this.
Applying a Discount While Generating an Invoice
It's a good idea to...
Create a specific Discount if it is going to be used multiple times (e.g. running a promotion or offering a discount to a particular group) to track it easily in the Reports section. See Creating a Discount for more details.
1. After Generating an Invoice, click on the box below to apply a Discount.
2. Click on the arrow to the right of No Discount to open the list of available Discounts.
3. Choose the appropriate Discount from the drop-down list.
4. If Manager Discount is selected, key in the amount to be deducted from the Invoice. If another discount is selected, the set amount or percentage will be deducted from the Item total.
5. Click Ok.
6. Ensure the proper amount is now shown in the Totals.
Adding a Discount to an Existing Invoice
Discounts can only be added to Invoices upon generation; if a discount needs to be added after an invoice is saved it can be done just like an adjustment.
