Best ACH Payment Software in 2026

An ACH payment tool moves US dollars between bank accounts on the Automated Clearing House network, as a debit you pull or a credit you push. A card checkout and a general ledger are different products, and neither one clears a US bank debit on its own.

A collection debit suits a business that wants the customer's bank account charged on a schedule. GoCardless prices that pull by plan, and Faster ACH stays off the cheapest plan, so the entry price buys the slower window. Stripe prices standard settlement and two-day settlement as two rates, so faster cash is a separate bill. Braintree prices standard ACH and same-day ACH as two rows on its US fee table, so the debit can stay in that gateway.

An invoice debit suits a business that already sends bills from Square. Square charges a percentage with a minimum and no monthly fee, and on its free plan it does not cap that percentage, while Invoices Plus and Premium cap ACH at $10, so a large free-plan invoice is where it gets expensive.

An origination API suits a company that creates the ACH file itself. Increase prints next-day and same-day origination, then sends platforms that move customer funds to a custom quote, so the public rate is not a marketplace contract. Finix prints a platform ACH schedule, including validation, for companies that let others accept ACH. Dwolla offers Standard ACH, Same Day ACH, and instant rails, and publishes no list price, so it stays off a spreadsheet until the order names a dollar.

A vendor credit suits a company paying bills it already approved, the opposite of collecting. Melio meters free ACH by plan, then charges past the allotment, so the free seat is only a small batch. Authorize.net is eCheck on a gateway, limited to US businesses, with a monthly fee even in a quiet month, so an occasional debit still pays that floor.

A payment-operations layer suits a team that wants ACH, wires, and real-time rails on one ledger. Modern Treasury describes annual, usage-based terms and does not print the commitment, so you cannot rank it on price this week. Paying contractors you already classified is the contractor payment guide. The invoice document itself is the invoicing software guide.

The expensive miss is copying a headline percentage and ignoring the cap, the window, and the return. An uncapped percentage on a large invoice costs more than the same invoice on a capped debit.

GoCardless international collection is 1.5% plus the fixed fee on Standard, 1.75% on Advanced, and 1.9% on Pro, with no domestic cap and sales tax excluded, so a cross-border pull can blow the US budget. Faster ACH, which the support page calls Same Day ACH, sits on Advanced and Pro only, stops at $1,000,000, and normally pays a US bank in two business days under that limit, then falls back above it. Custom payment pages are $50 a month on those two plans, so skip them when the hosted page is enough. A failure fee equals the Standard domestic cap, and a chargeback fee matches it only after more than 15 chargebacks in a month. Success+ is the retry tool GoCardless says recovers 70% of failed payments on average, not a promise on your file.

Stripe puts a validation charge, a failed-payment fee, and a dispute fee on its card, on top of the debit. Two-day settlement does not restate the standard cap, so faster cash can drop the ceiling. Standard settlement is 4 business days, cutoff 21:00 US Eastern, and two-day settlement is 2 business days, cutoff 14:00 US Eastern, for eligible US users, so the faster option also closes earlier. Stripe sets a minimum payment equal to the next-day figure in the Increase row, so a smaller debit is rejected before any fee applies. Partial refunds are not offered, and a full refund can be filed for 180 days. Disputes run 60 days and cover the full amount. Link's instant bank payments are 2.6% plus 30¢, a different product, so keep that rate out of an ACH budget.

Increase prices same-day origination, returns, and real-time rails as flat fees on its card. Monthly fees vary by use case and are not printed, so the per-transfer line is not the whole invoice. A platform moving customer funds is sent to custom pricing, and the printed card is not that contract.

Finix charges the platform ACH fee on failures as well as successes, and again when the account is tokenized, even if that bank was validated before. The same-day payout line applies to card volume, not to a cheaper ACH.

Square does not cap its invoice percentage on the free plan (Invoices Plus and Premium cap ACH at $10), and each ACH transaction is limited to the size in the comparison table, so a large invoice can cost more than a capped debit and still be too big for one pull. A failed ACH payment has no hidden fee, which is the trade for that missing ceiling, and funds typically show in two to three business days after a Plaid login. Braintree's US table does not return transaction fees on a refund, so a reversed debit still costs the original fee.

Melio's annual Core seat is $20 a month plus $8 a month per extra user once you need the larger bundle on the card. Boost is listed at $44 a month and at $55 a month, with 50 free ACH payments and QuickBooks Desktop, so confirm which price the order uses. A global ACH in USD is $20, apart from the domestic allotment. Same-day ACH sits outside that allotment and uses the maximum on the card.

Authorize.net adds an eCheck minimum in a quiet month on top of the gateway fee, and eCheck is US-only, so a company outside the US cannot use this row. The percentage has no published cap, so a large debit keeps climbing. Dwolla stops cancellations at 4pm CT, and same-day clearing needs Scale approval, so a self-serve signup misses the faster window. Addenda stop at 80 characters, so a long invoice reference has to live outside the record. Modern Treasury confirms an annual minimum and does not print it, so this week's spreadsheet cannot include a dollar.
