Card processing is a silent margin killer in this industry. Most operators are on the default Stripe or Square rate (2.9% + $0.30 per transaction) and have never compared it. On a business doing $1M in annual card revenue, the difference between 2.9% and 2.3% effective rate is $6,000/year — pure margin. Here's how to actually lower the rate without adding friction for your customers.
The three pricing models
Copy link to section: The three pricing models- Flat rate (Stripe, Square, PayPal) — 2.6%–2.9% + $0.30 across all card types. Simple, expensive at volume.
- Interchange-plus — actual interchange (set by Visa/MC) + a fixed markup (e.g. 0.30% + $0.10). Cheaper at volume; requires a real merchant account.
- Tiered — qualified, mid-qualified, non-qualified rates. Mostly outdated; almost always overpriced. Avoid.
Flat rate is fine under ~$300k/year in card volume. Above that, switch to interchange-plus.
Where you're probably overpaying

- Default flat rate above $500k/year volume. Switching to interchange-plus typically saves 0.4–0.7%.
- No corporate card surcharge program. Corporate Visa/MC interchange runs 2.5–3.0% — high. A legal cash-discount or surcharge program offsets this.
- Manual key-in for in-person bookings. Manually entered cards run 0.5–1.0% higher than tap/dip. Use a hardware reader for in-person.
- Authorize-only with multi-day capture. Holds longer than 7 days reauthorize at higher rates. Capture promptly.
- No address verification (AVS) on phone bookings. AVS-failed transactions run 0.3–0.5% higher.
Any one of these is worth fixing.
Surcharge / cash discount: legal and underused
Copy link to section: Surcharge / cash discount: legal and underusedIn most US states, you can legally: - Add a 2–3% surcharge on credit card payments (must be disclosed) - Or, advertise a "cash discount" off the regular price for cash/check/ACH
Both shift the processing cost to the customer. Corporate accounts often accept ACH instead of card to avoid the surcharge — saving you the entire 2.5–3.0% interchange. Worth $25,000–$80,000/year for a mid-size operator.
State-by-state rules vary; consult counsel before launching.
ACH for corporate accounts

Most corporate clients prefer ACH anyway — easier on their AP team, no card-on-file management. Just ask. Most will say yes.
Negotiate annually
Copy link to section: Negotiate annuallyEffective rate above 2.5% on a healthy book of business is grounds for a renegotiation conversation. Either your current processor matches the market or you switch.
The leverage in the conversation: - 12-month volume statement - Quote from a competitor - Willingness to sign a 12-month or 24-month commitment in exchange for the lower rate
Most processors will give you 0.10–0.30% discount to keep the business when pressed.
