Chase Payment Solutions in 2028: Interchange plus vs. flat rate

Chase Payment Solutions offers two distinct fee structures: standard flat-rate pricing with fixed percentage floors and custom Interchange Plus pricing that separates network costs from processor margins. Standard flat-rate pricing sets a uniform fee regardless of the card type presented at checkout. It charges 2.6% plus $0.10 for in-person transactions, 2.9% plus $0.25 for e-commerce sales, and 3.5% plus $0.10 for manual key-in entries.

Custom Interchange Plus pricing passes wholesale card network interchange rates directly to the merchant alongside a pre-negotiated processor markup. Wholesale network costs vary by card product, such as Visa Credit CPS Retail at 1.51% plus $0.10 or Mastercard Consumer Credit Merit III Core at 1.65% plus $0.10. Predictable flat billing suits smaller operations, but high-volume merchants use custom Interchange Plus to eliminate unnecessary margin markups on lower-cost card types.

High-volume US merchants bleed margin on percentage-based flat rates. Uniform pricing applies massive percentage markups to debit transactions that carry minimal wholesale cost under federal regulations. Regulated debit card interchange rates for Visa US Visa Debit CPS Regulated and Mastercard US Mastercard Debit Regulated max out at 0.05% plus $0.22 per transaction. Yet under Chase's standard flat pricing, accepting a regulated debit card costs the merchant 2.6% plus $0.10 in-person or 2.9% plus $0.25 online.

On an Interchange Plus model, the processor passes along the exact network interchange cost of 0.05% plus $0.22 alongside a negotiated processor margin. This structure lets merchants keep the savings generated by debit transactions rather than handing that fee differential to the processor. Card-present interchange rates sit lower than card-not-present rates, so physical storefronts pushing heavy debit volume capture massive operational savings once they drop flat-rate schedules.

According to ClearSale's published payments analysis, a business processing 100 orders per day at a $25 ticket price that moves from a standard 2.9% plus $0.30 flat rate to Interchange Plus captures estimated annual savings of approximately $16,200 for e-commerce storefronts or $22,140 for brick-and-mortar locations.

Across the merchant statements we analyze, Chase Payment Solutions delivers a blended effective rate of 2.76% for businesses utilizing custom pricing structures. Merchants calculate this metric by dividing total monthly processing fees by total processed sales volume and multiplying by 100. It provides an unsparing benchmark of total payment costs.

Our statement data shows custom account setups compress processing overhead well below Chase's advertised rates of 2.9% plus $0.25 for e-commerce and 3.5% plus $0.10 for manual key-in entries. Conversely, single user-review claims report a higher blended effective rate of 3.20% across 1 observation. This reflects smaller accounts trapped on standard flat rates or unoptimized merchant tier structures.

Unbundling wholesale network fees from processor overhead exposes exactly where merchant dollars go. Card association assessment fees typically sit between 0.08% and 0.10% of monthly transaction volume. When high-volume merchants negotiate custom Interchange Plus terms, the processor markup shrinks to cover only essential clearing services. This drives the merchant's total cost down toward true parity with wholesale network realities.

Merchants qualify for custom Interchange Plus pricing by meeting traditional merchant account underwriting criteria. This strictly requires at least 12 months of processing history and over $50,000 in annual processing volume. Payment aggregators let small businesses bypass formal underwriting, but high-volume sellers need dedicated merchant accounts to access negotiated fee structures.

The underwriting process for a direct Chase merchant account takes 2 to 3 days. To abandon standard flat rates of 2.6% plus $0.10 or 2.9% plus $0.25, eligible business owners must negotiate lower rates by calling a Chase Payments Advisor at 1-877-843-5690 to present their processing history and demand custom quote-based pricing.

During negotiations, merchants must reject tiered pricing models that group transactions into qualified, mid-qualified, and non-qualified buckets. Processors routinely round these fees up to the highest tier to pad their margins, forcing merchants to read a Chase statement for non-qualified rates just to identify the markups. Securing a direct Interchange Plus account guarantees transparency, backed by network rules that force processors to provide 120 days' notice before introducing new fees.
