Three ways California merchants keep more

CMS sells only these three customer programs. Each page below is written for California operators — not a thin copy of the national program pages.

Option 1

Flat Rate

One clear blended rate for card sales. Built from your statement or your industry and payment mix — easy to compare with what you pay today.

  • Available nationwide, including California
  • Credit + debit in one simple number
  • Strong when you want predictable pricing

Option 2

Surcharge

Keep cash prices the same. Where California allows with clear disclosures, eligible credit can include a surcharge — typically up to 3%. Debit and prepaid are never surcharged.

  • Available in California with CMS disclosure review
  • Debit never surcharged
  • Often the biggest monthly savings
