Credit surcharging adds a percentage to credit card orders under the Global Payments surcharge program. There are two halves to it, and only one of them is yours to do.

What you cannot do yourself

The surcharge feature itself is enabled and pushed to the device by the SIP team. There is no switch for it in the Admin Console. Raise the request through your normal support channel first.

What you must configure: the receipt clause

Before the location can use surcharging, its customer receipts have to carry a notice.

1. In the Admin Console Main Menu, click Location Setup, then Customer Receipt.
2. Select the Show Surcharge Clause check box.
3. A Credit Surcharge Amount box appears below it. Enter the correct percentage. The default is 3 percent.
4. Click Save.

What the guest sees

Printed receipts carry a notice that a surcharge may be added if they pay by credit card.

When a guest does pay by credit card, the surcharge appears on the receipt as a clearly labelled Surcharge fee.

Before you turn this on at a site

Surcharging is regulated and the rules differ by state and by card brand. Confirm the percentage entered matches what was agreed and disclosed. Signage at the door and at the register is part of the program, not an optional extra.

Debit is not surcharged. If a site reports a surcharge on a debit transaction, that is a real defect, not a configuration question.
