What's inside
01 · The Ecosystem
Who takes a cut of every swipe
When a customer taps a card, the money flows through an entire ecosystem before it reaches your bank account — and nearly everyone in the chain takes a piece. Knowing who's who is the first step to knowing what you're actually paying for.
💳 Card networks
Visa, Mastercard, Discover, American Express. They set the rules and the interchange rates. Their fees are non-negotiable — for everyone.
🏦 Issuing banks
The banks that give consumers their cards. They receive the interchange fee on every transaction — it's how card rewards get funded.
⚙️ Processors
Only a handful of companies actually process transactions in the US. Nearly everyone else in the industry buys from them and resells.
🏢 ISOs (resellers)
Independent Sales Organizations buy processing at wholesale and mark it up. Many sales reps work for ISOs without saying so.
🏛️ Banks as resellers
Some banks process directly; others resell another processor's service under their own brand. The branding tells you little about the cost.
👤 Sales reps & agents
W2 reps or independent agents. Their commission usually comes from the markup on your rates — which shapes what they recommend.
02 · Follow the Money
How a transaction actually works
Every card payment happens in two phases: authorization (seconds) and settlement (end of day). Here's the chain of events between the tap and the deposit.
Authorization — in 1–2 seconds
Customer pays
The card is tapped, dipped, or keyed at your terminal or checkout page.
Request goes out
Your terminal sends the transaction to the acquiring bank (your processor's bank).
Issuing bank checks
The customer's bank verifies funds or available credit.
Approval comes back
An authorization code travels back through the chain to your terminal.
Settlement — at end of day
Batch close
Your day's transactions are sent together to the card networks.
Funds requested
The networks collect funds from each issuing bank involved.
Interchange comes out
Issuing banks deduct interchange, then forward the rest to your processor.
Processor takes its cut
The processor deducts its fees and deposits the remainder into your account.
03 · Your Bill Explained
The four parts of your bill — and the only one that's negotiable
Your total processing cost has four components. Two are set rates every provider pays identically. One is the provider's profit. One is a grab bag. Everything in this guide flows from telling them apart.
| Component | Who gets it | Negotiable? |
|---|---|---|
| 1. Interchange — typically 60–70% of your bill. Varies by card type, entry method, and your business category. | Cardholder's bank | No |
| 2. Dues & assessments — the networks' fee for running the rails, charged on every transaction. | Card networks | No |
| 3. Processor markup — everything above the first two. This is the provider's gross profit. | Your provider | Yes |
| 4. Miscellaneous fees — statement fees, PCI fees, and friends. Some legitimate, many junk. | Your provider | Sometimes |
What a $100 rewards-card transaction looks like
A regulated debit card flips the picture: interchange drops to pennies, and the processor's markup becomes the largest share of the cost. That's why your card mix matters as much as your rate — and why a single blended number can hide so much.
04 · Know Your Options
Pricing models, ranked by transparency
Most business owners end up in the most expensive pricing models simply because nobody explained the difference. Here they are, worst to best.
| Model | How it works | Transparent? |
|---|---|---|
| Tiered / bucket | Transactions sorted into "qualified" tiers — and the provider decides which tier each one lands in. Most volume drifts to the expensive buckets. | No |
| 2-tier | A teaser rate for a few card types, much higher rates for the rest. Same opacity, different wrapper. | No |
| Flat rate | One rate for every card. Simple to understand — and impossible to audit, because the margin varies wildly per transaction underneath. | Partly |
| Interchange-plus | The networks' actual cost plus a separately disclosed markup. The only model where you can see exactly what the provider earns and compare offers apples to apples. | Yes |
05 · Hidden Costs
The fee list — what's legitimate, what's junk
The oldest trick in the industry: advertise a low rate, then recover it with a long tail of monthly, annual, and incidental fees. A "2%" quote with $60/month of add-on fees isn't a 2% quote. Here's the field guide.
| Fee | What it is | Verdict |
|---|---|---|
| Statement fee | Paper statement delivery | Often waivable |
| PCI fee (monthly/annual) | Compliance scanning & admin | Question it |
| Non-compliance fee | Penalty for not filing your PCI questionnaire | Avoid by staying compliant |
| Data breach protection | Breach insurance add-on | Usually unnecessary |
| Online reporting fee | Access to your own dashboard | Should be free |
| Gateway fee | E-commerce payment gateway | Legitimate if you sell online |
| Monthly minimum | Floor charge if volume dips | Push back |
| Batch fee | Per daily batch close | Small, but ask |
| Chargeback fee | Per dispute processed | Standard; sometimes negotiable |
| Early termination fee | Penalty to leave | Never agree |
| Terminal lease | Monthly equipment rental | Never lease — buy |
06 · Protect Your Business
Chargebacks & PCI, briefly
Chargebacks happen when a card company reverses a charge — usually from fraud, but also from misrepresented products, defects, or late delivery. The playbook is mostly common sense: prefer chip/tap over swipe in person; online, ship to billing addresses, use AVS, and require the CVV. Respond fast to unhappy customers — a prompt refund is far cheaper than a dispute, and excessive chargebacks can put your merchant account itself at risk. Deeper dive: chargeback fees explained.
PCI compliance applies to any business that accepts cards. For most small businesses it means an annual Self-Assessment Questionnaire and possibly quarterly scans. The trap to avoid: monthly "non-compliance fees" of $15–$35+ charged when you haven't filed the questionnaire. The fee is real and avoidable — file the SAQ. More: PCI fees explained.
07 · How to Choose
Six rules for evaluating any provider
These rules work on every offer — including one from Inspivo, the processor that powers this site. A fair provider passes all six without flinching; that's the point.
Get the complete quote in writing — on the evaluation form below
Have the rep complete and sign it before you decide anything. The signature turns a sales pitch into a commitment. If they refuse to sign, that tells you everything.
Never agree to an early termination fee
A provider confident in its service doesn't need to lock you in. Narrow exception: if you received upfront funds to cover switching costs, a fee matching those exact costs can be fair.
Ask: "Are my rates guaranteed, and for how long?"
A low rate that drifts up in month three is worthless. If rates aren't guaranteed beyond direct interchange changes, expect the classic bait-and-switch.
Buy equipment — never lease
See the math above. There is no version of a terminal lease that works in your favor.
Insist on interchange-plus pricing
It's the only model you can audit. A rep who resists is protecting a margin from your view.
Check track record — with context
Years in business and complaint resolution matter more than raw complaint counts; bigger companies naturally accumulate more.
08 · Your Protection
The Processor Evaluation Form
Print one copy per provider you're considering. Have each sales rep complete it fully and sign at the bottom — their signature certifies that all fees are disclosed and the quote is accurate. Then compare the completed forms side by side. Any provider unwilling to sign has answered your real question.
