How to Accept ACH Payments for Invoices

By the Clientary team · Updated October 7, 2026

To accept ACH payments for invoices, connect a payment processor that supports ACH, such as Stripe, to your invoicing tool, and let clients pay from their US bank account through a link on the invoice. ACH usually costs much less than card processing, especially on large invoices.

For service businesses sending invoices in the thousands, the difference between card and bank fees adds up fast. Here's how ACH works, what to watch for, and how to set it up.

How to start accepting ACH payments

  1. Choose a processor that supports ACH. Stripe supports ACH Direct Debit, and many invoicing tools connect to it.
  2. Connect it to your invoicing. So every invoice can carry a pay-by-bank option.
  3. Have clients verify their bank account. Usually through instant bank login or small test deposits, done once.
  4. Send invoices with a pay link. The client chooses bank payment and confirms.
  5. Watch for settlement. The payment shows as pending until it clears, then paid.

Tips for getting clients to pay by bank

  • Pass on card fees, but not bank fees. If you add a processing fee to card payments and waive it for ACH, clients have a reason to choose ACH.
  • Save the account for next time. A verified bank account can pay future invoices in one click, or automatically.
  • Use it for recurring work. Retainers and monthly invoices are ideal for automatic bank payments.
  • Invoice promptly. ACH takes a few days to settle, so don't add a delay of your own.

Frequently asked questions

What is an ACH payment?

ACH is the US network banks use to move money electronically between accounts. An ACH invoice payment pulls the amount from your client's bank account into yours, without a card or a check.

Is ACH cheaper than accepting credit cards?

Usually, yes. ACH processing fees are typically much lower than card fees, and some processors cap them, which makes the biggest difference on large invoices. Check your processor's current pricing.

How long do ACH payments take?

Typically a few business days to settle, longer than a card payment. Build that into your cash flow, and send invoices promptly.

Can an ACH payment fail?

Yes. A payment can be returned if the account has insufficient funds or the details are wrong, sometimes several days after it was made. Your processor will notify you, and the invoice will show as unpaid again.

Can clients outside the US pay by bank transfer?

ACH is US-only. Clients in Europe can pay euro invoices by SEPA Direct Debit, which works in a similar way.
