What Card Processing Really Costs, at a Glance

The percentage on the homepage is the part everyone compares — and the part that tells you the least. The real cost of taking cards is that rate plus a handful of smaller fees underneath it, and the honest measure is your effective rate: total fees divided by total sales. This guide walks through flat-rate vs interchange-plus pricing, every hidden fee by name, and how to compare two offers the fair way. There's a printable 29-page version up top.

Common Questions

1 What's the difference between flat-rate and interchange-plus?

Flat-rate (Square, Shopify style) bundles everything into one simple percentage plus a few cents — easy to read, usually no monthly fee. Interchange-plus shows the wholesale cost plus a fixed markup; it can cost less at higher volume but the statement is harder to read.

2 What is my 'effective rate'?

Your total fees divided by your total card sales, as a percentage. It folds in the headline rate and every hidden fee, so it's the only fair way to compare two processors. Compute it on a real month of your own sales.

3 What fees hide below the headline rate?

Monthly/account, PCI (and the non-compliance penalty), statement, batch, gateway, monthly minimum, chargeback, address verification, cross-border, network assessment, early termination, and equipment lease. Flat-rate systems bundle most away; contracts often add them back.

4 Is a low headline rate always the cheapest deal?

No. A rock-bottom rate stacked with monthly, statement, and gateway fees can cost more than a slightly higher flat rate with none. Add up a full month and compare effective rates, not headlines.

5 What's this PCI fee, and the penalty?

A charge tied to the card-security standard (PCI DSS v4.0.1 as of late 2026). The fee is minor; the separate non-compliance penalty is often avoidable by completing a short self-assessment. Ask your processor which questionnaire applies.

6 Should I watch for a 'free' terminal?

Yes. A free terminal is often tied to an equipment lease or a longer contract that can cost several times the hardware's price. Prefer buying your reader outright — our terminal-leases guide explains the traps.

Would you rather I just do this for you?

No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.

Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
