Card processing

Card processing ranking: high volume (2026, draft)

Only processors that fit high volume are ranked here, with adjusted weights. The overall ranking is always available too.

Updated Oct 2, 2026Methodology v0.1.0 · Draft

Over about $100k a month in card sales: interchange-plus pricing and every tenth of a percent weigh more.

Weigh more here than in the overall ranking: 12-month cost of the reference restaurant and published pricing. Weigh less here: what leaving in month 12 costs, contract term, no equipment lease you can't cancel, automatic renewal, and equipment works with another processor.

The ranking

    By Helcim

    RTC SCORE

    8.1

    #1 for High volume

    Pros

    • Published interchange-plus markup with automatic volume discounts: 0.40% + 8¢ in person up to $50k a month, lower above that.
    • No monthly, PCI, statement, annual or batch fee, and no cancellation fee: month-to-month.
    • Fee Saver credit card surcharge with no program fee: your customers pay 3% on credit cards and you keep paying the normal rate on debit. In person it currently works only on the Helcim Smart Terminal.

    Cons

    • No integration with restaurant POS systems such as Toast, Square, Clover or Lightspeed is documented; in-person payments run on Helcim's own app and devices (or its terminal API).
    • Online and keyed-in payments carry a higher markup: 0.50% + 25¢ up to $50k a month.
    • Support isn't 24/7: phone Monday to Friday 7 AM to 5 PM and Saturday 9 AM to 5 PM, Mountain Time.

    RTC SCORE

    7.9

    #2 for High volume

    Pros

    • Published markup for restaurants: interchange + 0.15% + 8¢ in person, and 0.10% for high volume or tickets of $25 or less.
    • A public table of every fee, with no PCI, batch, annual, AVS or monthly minimum fees.
    • No early termination fee; leaving costs $49.

    Cons

    • A $20 monthly fee, and Dharma says it doesn't make sense below a few thousand dollars a month.
    • The credit card surcharge costs $25 a month extra (or 0.12% on Clover), and debit stays at the normal rate.
    • Both bank program guides it publishes state a 3-year initial term and let the bank set a reserve at its discretion and adjust your rates without notice if your volume or ticket change.
