@AAUWsue Welcome to the community. Last November Square sent out emails stating you can no longer charge a service charge. This is not Squares decision, it was made by the credit card companies and Square has to follow their rules.
This is the statement from Square.
Surcharging not supported
Because payment networks recently updated their rules around credit card surcharging, Square cannot support surcharging at this time, and you cannot use the service charge feature to add a credit card surcharge. Surcharging is not permitted on debit cards, prepaid cards, or Afterpay transactions. Surcharging is also subject to local laws and regulations that apply to your business and must comply with card network rules, including notification requirements.
I know some people still charge a service fee and Square hasn't done anything to them, Some have reported that their account was suspended for charging a service fee.
