How we chose the best ACH payment platforms^†

In this list, we considered ACH platforms based on:

• Workflow depth versus rail access. Whether you get a finished approval-and-payment workflow, or a set of APIs you build on.
• Total cost of ownership. Published pricing where available, plus per-transaction ACH fees and what each tier includes.
• Fit for different business types. From micro-businesses paying a few bills to enterprises with multi-entity structures and global payees.

Common questions about ACH payment platforms

What is an ACH payment platform?

An ACH payment platform is software that moves money between bank accounts over the Automated Clearing House network. ACH is a federally regulated network of financial transactions, and ACH payments are electronic payments that go through the network, directing money from one bank account to another through a secure system. [3]

Platforms in this category differ mainly in what surrounds the transfer. Some are payment infrastructure, offering APIs that let a software company build bank transfers into its own product. Others are complete applications that capture invoices, route approvals, send the payment, and sync the result to accounting software. A business shopping for "an ACH platform" is usually shopping for one of those two things, and the right answer depends on which.

How does an ACH payment work?

Funds move from one bank account to another with the help of a secure, centralized system managed by NACHA (the National Automated Clearing House Association). To complete payments, the organization requesting a payment needs to get four key bank account details from the other party involved—whether they're sending or receiving funds: the name of the financial institution where funds are being sent, the type of account at that bank, the bank's ABA routing number, and the recipient's account number. [3]

Within an AP platform, the flow generally runs like this:

1. Invoice intake. Bills arrive by email, upload, or mobile photo, and the platform extracts the amount, vendor, and due date.
2. Coding and review. The invoice is coded to the right accounts and checked for duplicates or discrepancies.
3. Approval routing. The invoice goes to the right approvers based on your rules, with tracking and reminders.
4. Payment. The approved bill is paid by ACH or another method. With BILL, the platform debits your bank account on the process date, waits 2–3 days for the settlement of the debit, then credits your vendor's bank account. [3]
5. Sync. The transaction posts back to your accounting software so the general ledger stays current.

What features should you look for in an ACH payment platform?

• Fee structure. Whether ACH is priced as a flat fee per transaction or as a percentage of the payment, and whether there's a cap.
• Invoice intake and coding. Whether the platform captures bills automatically or expects you to key in every payment.
• Approval workflows. Multi-level routing, mobile approvals, reminders, and an audit trail for every action.
• Payment speed options. Standard ACH plus faster options when a deadline is tight.
• Accounting and ERP sync. Native two-way sync with your accounting system, and which plan tier it requires.
• Vendor onboarding. Whether vendors maintain their own payment details or you collect and store bank information yourself.
• Fraud controls. Duplicate detection, suspicious activity monitoring, and separation of duties.

How much does an ACH payment platform cost?

ACH platform pricing splits into a few distinct models:

• Flat per-transaction fees. BILL charges $0.59 for an ACH or ePayment sent from a bank account, BILL Balance, or BILL Cash Account, on every plan, on top of subscriptions starting at $49 per user per month. [1]
• Percentage-based fees. Stripe's pricing page lists ACH Direct Debit at 0.8% with a $5.00 cap. [6]
• Included-volume subscriptions. Melio's plans bundle a monthly ACH allowance—5 on the free Go plan, 20 on Core, 50 on Boost, unlimited on Unlimited—with a $0.50 charge per payment after the allowance is used. [16]
• Subscription plus transaction pricing. Tipalti lists Accounts Payable plans starting at $99/month with transaction pricing per invoice and payments applied on top. [7]
• Custom pricing. Dwolla and Modern Treasury both direct prospective customers to a sales conversation rather than publishing rates—Dwolla based on transaction volume, rails, and integration needs, and Modern Treasury based on volume, rails used, and account structure. [9][14] Coupa does not publish pricing for Coupa Pay on the pages reviewed. [11]

When comparing, check the fee for the specific transaction type you'll use most. A percentage-based fee and a flat fee can produce very different totals at the same payment volume, depending on the size of each payment.

Benefits of paying vendors by ACH

Lower cost than checks and cards. For businesses who pay credit card fees to accept payments, or third-party check processing fees to make payments, ACH is a more cost-effective solution. [3] Paper checks cost the most to use when you factor in the time, supplies, and bank fees. [3]

Reduced check fraud exposure. Paying vendors with digital payments reduces the risk of paper check theft. [3] Platforms that keep your bank account information private from vendors add a further layer—BILL makes digital payments through your account rather than exposing your account details. [3]

Clearer cash flow timing. With an ACH transfer, the debit is reflected on your account immediately, so there's no guessing game. You're able to schedule ACH transfers for specific dates, or as recurring payments, for clearer visibility into and greater control over your cash flow. [3]

Less manual work when it's integrated. Most online banking platforms offer ACH capabilities, but the lack of integration with key workflows results in lots of manual work—especially for businesses with more than a handful of payments each month. [3] Platforms that combine ACH with invoice intake and approvals remove that gap.

Faster options when timing matters. Standard ACH runs on a multi-day cycle, but faster paths exist. BILL offers Instant Payments that can arrive in minutes, with a 1% fee.* [3]
