Businesses that accept credit card payments often encounter unfamiliar charges on their merchant statements. The FANF charge represents one of the most misunderstood fees that Visa includes in its network fee structure. Many merchants mistakenly consider this fee as a processing charge because it usually accompanies their other processing fees. 

The FANF charge explanation needs to be understood by businesses that want to control their payment processing expenses. The Fixed Acquirer Network Fee (FANF) functions as a permanent charge that payment processors cannot negotiate with their customers. Visa determines this fee, which acquiring banks use to implement it. 

However, confusion arises because some processors include additional fees on merchant statements that resemble the Visa FANF fee. These look similar but may be processor markups disguised as network charges. 

The article explains the fixed acquirer network fee, including its actual function, its non-existent aspects, its presence on merchant statements, and the method for detecting processor markups that may resemble it. 

Understanding the FANF Charge 

Visa assesses merchants a fee for accepting its cards – a fixed acquirer network fee (FANF). The fee was created to support Visa’s payment network operations. It will be assessed to the merchant through the merchant’s acquiring bank.  

Visa FANF is used to cover the costs associated with operating and maintaining the payment network. Examples of these costs include: 

  • Network infrastructure. 
  • Fraud monitoring systems. 
  • Ways to authorize payments. 
  • Network reliability and uptime. 

The FANF charge is generally calculated monthly, based on the merchant’s category of commerce and their processing volume. Therefore, unlike interchange fees, which can vary according to the specific transaction, the FANF is generally charged monthly. 

Since the FANF is assessed by the card network (Visa), not by the payment processor (merchant services provider), merchants cannot negotiate or waive this fee. 

Why the FANF Charge Appears on Merchant Statements? 

The majority of retailers realize they have been charged a FANF fee. Examining the merchant statement to review their different types of merchant statement charges. Many of these fees are located under labels such as: 

  • Visa network fees. 
  • Card network assessments. 
  • Card brand fees. 

Since an average retail merchant statement contains many lines. It can be difficult for a retailer to differentiate between card networks that are charged by their processor. 

The FANF fee originates from Visa and is passed through the processor or acquiring bank. The processor does not have control over what the amount of the fee is or why it is listed on the merchant statement. It is included in its statements for transparency reasons. Since the FANF fee is in the same section, the retailers believe that other fees are being charged. The FANF charge also has a markup applied by the processor. 

What the FANF Charge Is Not 

People need to learn about the FANF fee together with its actual definition. The statement that a fee is a processor markup becomes incorrect because it does not align with the fee’s actual definition. 

  • It Is Not a Processor Markup 

A processor markup functions as a supplementary charge that payment processors implement to create additional income streams. It consists of multiple fee structures that include per-transaction charges, percentage-based increases, and monthly service fees. The Visa FANF charge exists as the card network establishes it to be a mandatory charge for all Visa merchants. The payment processors only transmit this charge to their customers. 

  • It Is Not Interchangeable 

The interchange system functions through transaction-based fees, which merchants pay to banks that issue their cards. The fees for these transactions depend on multiple factors, such as the type of card used, the transaction method, and the type of business conducting the transaction. The FANF charge operates as a fixed network, which differs from the expense structure of per-transaction fees. 

  • It Is Not a Negotiable Fee 

The fee exists as a non-negotiable charge that businesses must pay. Merchants can sometimes negotiate processor markups with their payment provider. The FANF charge exists as a non-negotiable fee that Visa establishes through its fee schedule. This charge will remain in effect even if a merchant changes payment processors, as their business continues to accept Visa cards. 

How FANF Charges Are Calculated? 

Visa determines the FANF charge that merchants pay based on various factors, including: 

  • The type of merchant (merchant category). 
  • The processing volume of the merchant. 
  • The number of locations the merchant has. 
  • The type of transactions that the merchant processes (card-present or non-card-present). 

Small merchants with lower volumes of Visa transactions pay a relatively low monthly FANF charge compared to large merchants with high transaction volumes. Additionally, Visa provides fee schedules that detail how FANF fees apply to different types of merchants. 

Processor Markup vs Card Network Fees 

Merchants encounter difficulties when they attempt to distinguish between processor markup and card network fees. Monthly merchant statements display both types of charges. Their grouped presentation makes it hard to identify which fees come from card networks and which fees payment processors impose. 

Card network fees represent fixed costs that organizations like Visa and Mastercard established to fund worldwide payment systems. Payment processors impose processor markups as their service fees. This covers transaction routing, payment gateway accessibility, and customer support services. Merchants can assess their merchant statement fees by knowing this distinction, which enables them to find hidden credit card processing costs. 

Fee Type Who Sets the Fee Purpose Negotiable Example 
Card Network Fees Card networks such as Visa or Mastercard Maintain payment network infrastructure, fraud monitoring, and authorization systems. No Visa FANF fee (Fixed Acquirer Network Fee) 
Interchange Fees Issuing banks (regulated by card networks) Compensation to banks that issue credit cards No Credit card interchange rates 
Processor Markups Payment processors or acquiring banks Revenue for processing services, gateway access, and merchant support Yes (sometimes negotiable) Transaction markup, monthly service fee 
Additional Processor Fees Payment processor Administrative or platform-related costs Often negotiable Statement fee, PCI compliance fee 

In summary, the primary distinction between processor markup and card network fees stems from the fact that different entities control the respective costs. The FANF charge is a fixed fee that merchants must pay without the option to negotiate. 

Whereas payment providers impose processor markups that differ according to their respective processing needs. The difference between these two systems enables merchants to understand their processing statements better, which helps them find high or unneeded costs. 

Processor Markups That Look Like Network Fees 

Merchants have problems defining how much processors are charging them for network-like processing fees. Most processors included charge lines on the supporting documents that sound similar to card network fees or interchange fees. As an example of USA markup-type fees, there could be any number of those types of charges that processors impose, specifically:  

  • NAS (Network Access Fee) 
  • ISF (Infrastructure Support Fee)  
  • PFF (Platform Network Fee)  
  • RCF (Regulatory Compliance Fee)  

There could be many different fees that may be a processor’s true charge. However, if any type of mark-up charge is one that is similar to an official card network fee, like the fixed acquirer network fee. With all this information, it is evident as to why you would want to do further due diligence with regard to reviewing your breakdown on your merchant statements for possible discrepancies. 

How to Identify Processor Markups 

To detect possible merchant marketing compensation that can be mistaken for network fees, merchants can take various measures. 

  • Compare Fees Against Card Network Schedules 

Merchants can validate their transactions by comparing the fees on their monthly statements against the published card network’s official fee. If any fee on a merchant’s statement does not correspond to what is documented, then that merchant should consider the fee as a processor markup. 

  • Request Fee Transparency 

Merchants are encouraged to ask their processors to explain in detail all fees charged. A processor who is willing to be transparent should be able to distinctly disclose: 

  • Interchange fees 
  • Card network assessment fees 
  • Processor markup fees. 

This type of breakdown will assist merchants in determining the processor markup and the card network fee. 

  • Review Monthly Statements Carefully 

Consistently reviewing the statements, a merchant will be able to discover unknown or unexpected fees. In addition, individual merchants will watch out for any recurring fees each month, as legitimate card network fees. If any fees appear to have no justifiable reason for charging, the merchants should contact their processor for an explanation. 

Why Transparency Matters in Payment Processing 

Payment processing fees create major effects on the operational expenses of businesses. Merchants face the risk of paying high costs for card acceptance because they lack knowledge about actual payment processing costs.  

Businesses select payment processors to comprehend which fees constitute real network charges and which costs represent credit card processing expenses. Payment processors that deliver complete fee breakdowns and transparent billing statements establish trust with merchants. Hence, providing them with precise information about their expenses. 

Choosing a Transparent Payment Processor 

To evaluate payment processors, merchants should always prioritise those with transparent fee-based pricing structures. This type of processor generally has: 

  • Detailed fees for each cost component. 
  • Clear distinctions between network fees and processor costs. 
  • Standardised or simple pricing structures. 

They provide merchants with the necessary information to separate proper charges (i.e., Fixed Acquirer Network Fee, from other processor costs). 

Conclusion 

The FANF charge is a network fee that is set and paid by the merchants when they accept their Visa cards. The fee supports global payment network infrastructure, reliability, acquiring banks, and payment processors’ access to the merchants.  Multiple line items present in merchant statements make it simple for them to mistake the Visa FANF charge for processor markups and other processing expenses.  

Understanding the difference between processor markup and card network fees is essential for identifying the hidden fees for credit card processing. The review process requires businesses to examine their merchant statements while comparing official card network schedules. It also requests transparent pricing from processors to control their payment processing expenses. 

The fixed acquirer network charge works as a fee that merchants need to understand. This will finally help them choose better payment processing solutions and prevent an unnecessary increase in expenses.
