ACH processing fees: 5 ways to pay less.

A quick note on terms: an “eCheck” is simply an ACH debit collected online. We use the two interchangeably in this post.

If you accept ACH payments, you're probably overpaying. Not because ACH is expensive — it's the cheapest way to get paid — but because the pricing is designed to be hard to compare. Here are five ways to pay less, each with the math to prove it.

5 ways to pay less for ACH

1Go flat if your tickets top $100

Percentage pricing looks harmless until you do the division. A flat $0.75 beats Stripe's 0.80% on any ticket above $93.75, and beats Braintree's 0.75% above exactly $100. Below those lines, percentage is a few cents cheaper — above them, you're paying a surcharge on your own growth.

And tickets above $100 are the norm for ACH: the average B2B ACH payment is over $8,000. Businesses use bank transfers precisely for the large payments where percentages hurt most. If your average ticket clears $100 — and it almost certainly does — a flat rate wins every time.

2Compare the effective rate, not the sticker rate

A provider advertising $0.30 per transaction with a $40 monthly minimum costs a 100-transaction-a-month business $0.70 per transaction in practice (($30 + $40) ÷ 100). The sticker said thirty cents; the invoice says seventy.

This is the single most useful habit in payments: add up everything you paid the provider last month — per-transaction fees, monthly fees, minimums — and divide by your transaction count. Compare that number across providers, and the "cheap" options often stop looking cheap.

3Watch the monthly minimums and gateway fees

Some providers enforce a monthly minimum — $10/month in eCheck fees whether you process or not — on top of a $25/month gateway fee. That means your first $35 of "cheap" ACH fees each month is really fixed cost. At low volume, fixed fees dominate: 50 transactions at a $0.30 sticker rate with $35 in fixed fees is a $1.00 effective rate.

Small merchants should do this arithmetic before signing anything. A slightly higher per-transaction rate with no minimums frequently beats a low sticker rate stacked on fixed fees.

4Price returns into your model

ACH returns — insufficient funds, closed accounts, wrong numbers — run 0.5% to 1.5% of volume in most industries, and each one costs $2 to $5 in return fees. At scale that's real money, and it's the line item most businesses forget to model.

Two defenses: verify account details up front (most modern processors offer bank-account validation), and factor a 1% return rate into your cost projections. A provider whose return fees are $5 instead of $2 costs you meaningfully more at volume, even with an identical per-transaction rate.

5Don't pay for speed you don't need

Same-day ACH carries a surcharge at most providers — often around 1% — for settlement that's hours faster. But standard ACH settles in 2–3 business days at the base rate, which fits invoicing, recurring billing, and B2B payments fine. Unless you're racing a deadline, the surcharge buys you nothing.

And keep the real comparison in view: even the most expensive ACH option costs 80%+ less than cards on a $1,000 ticket. Don't let a $0.05 difference between ACH providers distract from the $28 you're saving versus credit cards.

The numbers behind the advice

Published rates, no sales call required. What a single transaction costs at three ticket sizes:

Two things jump out. First, at $100 everyone clusters around the same seventy-five cents — percentage pricing only looks cheap on small tickets. Second, not every provider caps the percentage — where there's no cap, the fee keeps climbing with the ticket: $37.50 and $50.00 on a $5,000 payment in the table above. That's the percentage trap.

The fees nobody puts on the pricing page

The per-transaction rate gets the headline. These get the invoice:

• Monthly gateway/account fees — $10 to $35/month. A $25/month gateway fee is common; many providers bury a similar line item.
• Monthly minimums — Some providers enforce a monthly minimum — $10/month in eCheck fees whether you process or not. Low-volume months still cost you.
• Returned-item fees — $2 to $5 every time a debit bounces for insufficient funds or a closed account.
• Dispute fees — $5 to $25 per unauthorized-transaction claim. Cheaper than the $15 card chargeback, but not zero.
• Setup fees — $0 to $99 one-time. Increasingly rare — most modern providers have dropped them — but some resellers still charge one.

None of these are scams — they're the real cost of running payment infrastructure, and there's nothing wrong with charging them as long as they're disclosed. The problem is opacity: a provider advertising "0.75%" while charging $25/month plus a $10 minimum is meaningfully more expensive than the headline suggests. Ask for the full schedule in writing. If a provider won't give it, that's your answer.

For the record, ours fits in one sentence: $0.75 per transaction, $25/month, no setup fee. That's the entire schedule — see pricing.
