Credit card processing fees are a combination of three elements:
Interchange fees – paid to the card-issuing banks.
Assessment fees – paid to Visa, Mastercard, Discover, and AmEx
Processor markup – what your provider charges to facilitate the transaction
The key difference between pricing models is how the markup is applied — and how clearly you can see it.
This “one-size-fits-all” model charges a single rate (for example, 2.9% + 30¢) for every transaction. It’s the structure used by popular services like Square, PayPal, and Stripe.
Pros: Easy to understand; Predictable monthly cost; No separate line items for interchange.
Cons: Usually higher overall costs; Doesn’t reward you for lower-cost cards; Limited transparency.
Best for: Startups, pop-ups, or small merchants processing under $10K/month.
Transactions are grouped into “tiers” — Qualified, Mid-Qualified, and Non-Qualified — each with a different rate based on card type and transaction method.
Pros: Simple on paper; Often bundled with free equipment offers.
Cons: Confusing real costs; Many transactions downgrade into higher tiers; Easy to hide markups and surcharges.
Best for: Merchants who prioritize simplicity but should review monthly statements carefully.
The most transparent and cost-efficient model for growing businesses. You pay the actual interchange and assessment fees — the true cost set by the card brands — plus a fixed processor markup (for example, +0.20% + 10¢).
Pros: Full cost visibility; Scales with your volume; Eligible for interchange optimization (Level-2/Level-3 data).
Cons: Requires statement literacy; May include small monthly fees.
Best for: Businesses processing over $25K/month or those with high average tickets, B2B companies, and multi-location merchants.
Some modern processors (including select NPS programs) charge a flat monthly membership fee instead of a percentage markup, passing interchange at cost.
Pros: Fixed monthly overhead; Ideal for high-volume merchants; Predictable expenses.
Cons: Monthly membership costs may exceed savings for smaller businesses.
Best for: High-volume retailers, e-commerce stores, or franchises exceeding $250K/month.
The more transparent the pricing, the easier it is to identify and reduce hidden costs.

A local HVAC company processed $80,000/month using a flat-rate processor at 2.9%. After switching to Interchange-Plus (2.2% effective rate) through Nationwide Payment Systems, they saved $560 per month — over $6,700 annually. That money went right back into marketing, inventory, and payroll.
Enable Level-2/Level-3 data for B2B cards — saves 0.30–0.50% per transaction.
Use Dual Pricing or Cash Discounting to offset fees legally and compliantly.
Batch out daily to avoid late fees and downgrades.
