# Can't apply a discount or fee directly to a counter sale (POS) invoice

## **What you're seeing**

You're building a counter sale (POS) invoice and want to take money off with a discount, or add a fee. There's no option to apply a discount or fee directly. The standard discount option doesn't work on a counter sale invoice.

## **Why this happens**

**Reason**

**A counter sale (POS) invoice doesn't support discounts or fees directly.** Discount tasks (the standard discount option) don't apply to it. To adjust the total, you add a pricebook service item instead.

## **Before you start**

**Add the discount or fee before you collect payment.** You can't edit a paid counter sale invoice.

> [!NOTE]
> **Caution:** Do not use this workaround to add a credit card surcharge or convenience fee. Fintech guidance is that discount and fee items are not compliant for card surcharging. Instead, increase prices and offer a cash discount.

## **How to fix it**

### **Add a discount or fee as a pricebook service item**

1. Go to the **Pricebook**.
2. Create a service item priced to match the adjustment: a **negative** price for a discount, or a **positive** price for a fee.
3. Add the item to a pricebook category that's assigned to the POS location, so it can be added to counter sale invoices.
4. Add the item to the counter sale invoice.

> [!NOTE]
> **✓ Done ·** The item appears as a line on the counter sale invoice and adjusts the total.

> [!NOTE]
> **Note:** A negative-price discount item behaves differently from membership discounts on counter sale invoices.
