Processing fees and pricing

What is flat-rate payment processing?

Direct answer

Flat-rate payment processing charges a stated rate for a defined transaction category, commonly combining underlying card costs and provider markup. Separate rates may apply to in-person, keyed, and online payments, and additional monthly, instant-transfer, chargeback, hardware, or software fees may apply. Its simplicity can aid forecasting, but the headline rate is not always the complete cost.

Key facts

  • One provider may publish several “flat” rates.
  • Card-present and card-not-present pricing often differs.
  • Bundling reduces visibility into underlying cost components.

Why merchants choose it

Straightforward rates can make early budgeting and statement reading easier, especially for businesses with modest or unpredictable volume. Setup and software packaging may also influence the choice.

Where comparison gets harder

A bundled rate may cost more or less than alternatives depending on average ticket, card mix, volume, channels, and included services. Contract and transfer terms remain important.

Channel comparison

A provider could price tap transactions at one percentage plus item fee and keyed transactions at a higher amount; both can still be described as flat-rate categories.

When the answer changes

  • Rates can differ by channel, feature, or plan.
  • International cards and currency conversion may carry additional charges.

Common mistakes

  • Assuming every transaction receives one identical rate.
  • Ignoring software and payout fees.

What to verify

  1. List rates for every acceptance channel.
  2. Price the full monthly stack at expected volume.
