Check with your credit card processor acquirer regarding the minimum purchase amount that you are allowed to charge. U.S. merchants may establish a minimum purchase
amount on credit card transactions. The minimum purchase amount must not exceed $10, must not differentiate between card issuers or card brand, and does not apply to transactions made with a debit card.
Adhere to any maximum purchase amounts on credit card transactions established by federal agencies or institutions of higher education. The maximum purchase amount must not differentiate between card issuers or card brand, and does not apply to transactions made with a debit card. In other countries, there are multiple variations of the "Minimum Purchase" rule, depending on local law and acquiring practices. Your acquirer can advise
you regarding permissible minimum purchase amounts.
What Visa says:
What is a convenience fee?
It varies slightly from one card brand to the next, but a convenience fee is basically a charge in addition to the original transaction amount for the privilege of being able to use an alternate payment method. It sounds like the same things as a surcharge, but it's not that easy.
By VISA's guidelines, surcharges are different than convenience fees. By MasterCard's definition "any fee charged in connection with a Transaction that is not charged if another payment method is used" is a surcharge. So technically, VISA says that convenience fees and surcharges are different and MasterCard says they're the same thing.
"Always treat Visa transactions like any other transaction. You must not impose
any surcharge** on a Visa transaction."
For merchants who offer an alternate payment channel (i.e., mail, telephone,
or e-commerce) for customers to pay for goods or services, a convenience fee
may be added to the transaction amount. If the merchant chooses to assess
a convenience fee to its customers, the merchant must adhere to Visa rules
regarding convenience fees.
For restaurant, taxicab, limousine, bar, tavern, beauty/barber shop, and health/
beauty spa merchant transactions with a Visa credit or debit card, authorize
only for the known amount, not the transaction amount plus estimated tip.
Cardholders now have the ability to check their credit or checking accounts
almost instantaneously via phone, the Internet, or an ATM. An authorization that
includes an estimated tip can reduce a cardholder's available funds or credit by
an unrecognizable or unexpected amount. This kind of transaction may occur if a
cardholder leaves a cash tip or adds a tip that is less than the estimated amount
used for authorization. For example, a restaurant authorizes for an estimated 20
percent tip, but the customer adds on only 15 percent.
