# Discounts

The two ways Veterian applies a discount to an invoice, how to change or remove one, and the legacy third method you may still see on older invoices.

Veterian applies a discount at one of two points in the invoice calculation. Both show the same figure on the page, but they do not leave the same figures on your tax return, so settle which method your clinic uses and keep to it.

## Where to Find This Section

On an invoice, find **Add Discount** at the bottom of the **Invoice Summary** and click the **+** beside it. Pick the method from the menu, then enter the amount.

## The Two Methods

### Apply discount to subtotal

The discount comes off the subtotal, before tax.

### Apply discount to invoice total

The discount comes off the invoice total.

In both cases the summary states which method was used, so anyone reading the invoice later can tell. With **Apply discount to invoice total** it also shows the **Applied discount amount**.

## Changing or Removing a Discount

Once a discount is on an invoice, **Add Discount** becomes **Change Discount**. The pencil beside it edits the amount and the eraser clears it entirely.

## The Legacy Third Method

Older invoices may carry a third method, **Apply discount to invoice amount (not recommended)**. It is not offered on new invoices, and stays selectable only on invoices that already use it, so those invoices can still be edited.

> **Warning**
> The software marks this method *not recommended* where it appears. Use one of the two current methods instead.
