Understanding Payment Processing Fees

At‑a‑Glance: Your statement lists pass‑through costs (interchange, assessments) and provider markups (basis points, per‑item, monthly fees). Focus on effective rate—total fees ÷ total card sales—and the levers that actually move it.

Interchange vs. Markups

  • Interchange & assessments: set by card brands and banks; vary by card type and entry method.
  • Provider markups: the negotiable part—basis points, per‑item, and monthly platform fees.

FAQ

Is a lower headline rate always better? Not if it raises downgrades or per‑item costs. Measure effective rate monthly.

Can I negotiate interchange? No—but you can qualify for better categories by submitting the right data.
