1. Switch to Interchange-Plus Pricing
Flat-rate and tiered pricing models bundle interchange costs with processor markup in a way that obscures what you actually pay. Interchange-plus pricing separates the two — you pay actual interchange set by the card networks, plus a fixed markup from your processor. For most businesses processing more than $5,000 per month, interchange-plus produces a meaningfully lower effective rate.
2. Audit Your Statement for Hidden Fees
Most merchant statements include fees that provide no value — PCI non-compliance fees, statement fees, batch fees, and monthly minimums that show up as line items most merchants never question. A free statement audit identifies every avoidable charge on your current statement.
3. Ensure Correct MCC Classification
Your Merchant Category Code determines which interchange category your transactions fall into. Processors occasionally assign the wrong MCC at onboarding, and the error compounds on every transaction. Verify your MCC matches your actual business type and request a correction if it does not.
4. Encourage Card-Present Transactions
Card-present transactions — where the card is physically swiped, dipped, or tapped — carry lower interchange rates than card-not-present transactions like online orders or phone sales. When in-person payment is an option, it is the lower-cost method.
5. Negotiate Your Processor Markup
The interchange component of your processing fee is non-negotiable — it is set by the card networks. The processor markup is negotiable, especially as your volume grows. Processors routinely offer better markup rates to merchants who ask, particularly those processing more than $25,000 per month.
6. Evaluate Surcharge and Cash Discount Programs
In most states, merchants can legally pass processing costs to customers through surcharge or cash discount programs. A properly implemented cash discount program can reduce your net processing cost to near zero on qualifying transactions. Compliance requirements vary by state — review applicable rules before implementing.
7. Set Up a Backup Processor to Avoid Emergency Placement
Merchants who lose their primary processor and need emergency placement often end up in high-risk accounts with significantly higher rates. Having a backup processor already in place before a disruption occurs keeps you out of emergency pricing situations.
