The Authorization fee (actually an authorization request fee) is charged each time a transaction is sent to the card-issuing bank to be authorized. The fee applies whether or not the request is approved. Note this is not the same as Transaction fee.
The Transaction fee is charged when you accept your authorization. This fee only applies to an authorization that is accepted without error.
The statement fee is a monthly fee associated with the monthly statement that is sent to the merchant at the end of each monthly processing cycle. This statement shows how much processing was done by the merchant during the month and what fees were incurred as a result.
Many times, the statement fee is not directly linked to "paper" statements but rather general overhead. This means that a provider would not waive this fee if a merchant chose to have a "paperless" statement.
Monthly minimum fee
The monthly minimum fee is a way to ensure that merchants pay a minimum amount in fees each month to cover costs from the provider to maintain the account. If a merchant's fees do not equal or exceed the monthly minimum they will be charged the difference up to the monthly minimum.
Example: A merchant has signed a contract with a $25.00 monthly minimum fee. If all the fees for the most recent month of processing total only $15.00, this merchant will be charged an additional $10.00 to meet their monthly minimum requirements. Sometimes there are fees that are charged that are not a part of the monthly minimum, such as statement fees. It is industry standard to charge a monthly minimum.
A batch fee (also known as a batch header fee) can be charged to a merchant whenever the merchant "settles" their terminal. Settling a terminal, also known as "batching", is when a merchant sends their completed transactions for the day to their acquiring bank for payment. Some providers perform this automatically. It is important to close a batch every 24 hours or a higher rate will be assessed by Visa, Discover or Mastercard. The term "batch header" originally came from processing pre-electronic terminal era, when each batch of credit card receipts was turned in to the merchant's local bank for deposit. The batch header was a mini report summarizing those receipts bundled within.
Customer Service fee
The customer service fee (also known as a maintenance fee) can be charged by some providers to pay for the cost of customer service. Also referred to as a "merchant support fee", "customer support fee", or simply, "service fee" by some merchant providers.
The Annual fee can be charged by some providers to pay for costs of maintaining the merchant's account. Sometimes these fees can be quarterly. The fee can be from $79–$399.
Early Termination fee
The early termination fee can be charged by some providers if the merchant ends the contract before the end of the contract term. While contract terms of 1–3 years are typical, some providers have terms of up to 5 years with a one year prior notice to cancel or the fee will be assessed. Some providers also assess all statement fees and monthly minimums remaining when the contract is terminated. Some providers may also assess a "lost profit" fee based on an assumption of profits they concluded they would have earned during the full term of the contract.
The chargeback is the largest risk that is presented to banks and providers. This is not to be confused with a refund, which is simply a merchant refunding a transaction. In the Visa, Discover, and Mastercard rules, the merchant's processing bank is 100% responsible for all the transactions that the merchant performs. This can leave the provider open to millions of dollars of potential losses if the merchant operates in an illegal or risky manner and generates many chargebacks. The providers pass this cost on to the merchant, but if the merchant is fraudulent or simply does not have the money, the provider must pay all the costs to make the card holder whole. The chargeback risk is the largest part taken into consideration during the contract application and underwriting process. Some banks are much more stringent than others when assessing a merchant's chargeback risk.
If a merchant encounters a chargeback they may be assessed a fee by their acquiring bank. A potential chargeback is presented on behalf of the card holder's bank to the merchant's credit card processing bank. A reason code is established by the card issuer to properly identify the type of potential chargeback based on the card holder's complaint. The most common complaint is that the card holder can not remember the transaction. Usually, these potential chargebacks are corrected when the merchant's processing bank sends over more details about the transaction. Some providers charge a fee for this service, known as a "Retrieval Request". A chargeback can also be related to a fraud or similar dispute that the card holder is claiming to the merchant. This fee can be charged by some providers whether the chargeback is successful or not and is not dependent on the amount of the chargeback.
Currently both Visa and Mastercard require all merchants to maintain no more than 1% of dollar volume processed to be chargebacks. If the percentage goes above, there are fines starting at $5000 – $25,000 to the merchant's processing bank and ultimately passed on to the merchant.
In all cases, a chargeback will cost the merchant the chargeback fee, typically $15–$30, plus the cost of the transaction and the amount processed.
