Payment Processing 101 by Mitchell Fleming Review 2026: Worth Reading?

Merchant statements are deliberately confusing, and the industry profits from your confusion. "Payment Processing 101" by Mitchell L. Fleming promises to decode interchange, markup, and the games processors play. Here is whether it earns a spot on a small business owner's shelf.

What the Book Covers — ~$20

The book walks through how a card transaction actually moves, what interchange is, how processors add markup, and the difference between flat-rate, interchange-plus, and tiered pricing. It dedicates real space to reading a merchant statement line by line.

What It Does Well

• Statement decoding: The walkthrough of an actual statement is the most valuable section — it pays for the book the first time you spot a junk fee.
• Pricing models: Clear, jargon-light explanations of why interchange-plus usually beats tiered for established merchants.
• Negotiation: Practical scripts for pushing back on a processor.

Where It Falls Short

• Pricing examples date quickly; treat specific rate numbers as illustrative.
• Light on high-risk and international processing.
• Not a substitute for reading your own contract.

Who Should Read It

Best for a new or growing small business owner who has never audited a merchant statement. If you already negotiate interchange-plus and audit fees quarterly, you will find it basic.

FAQ

Is it current for 2026? Concepts are evergreen; specific rates are not — verify current pricing independently.

Will it help me lower fees? Yes, mainly by teaching you to read statements and ask the right questions.

Is it technical? No — it is written for non-specialists.

Bottom Line

For about $20, this book reliably pays for itself by helping you catch padded fees and choose a fairer pricing model. Recommended for owners who have never seriously audited their processing costs.
