As a business attorney and consultant with over 12 years drafting payment agreements for U.S. companies, I’ve created and reviewed thousands of ACH authorization forms. One of the most frequent requests I receive from small-business owners, freelancers, property managers, and nonprofit leaders is a reliable, compliant, and completely free ACH authorization form template they can customize immediately.
In this guide, I’m giving you my battle-tested ACH form template — available in both Microsoft Word and PDF — along with step-by-step instructions, legal requirements under NACHA rules, and best practices that have helped my clients avoid disputes and chargebacks for years.

An ACH authorization form (also called ACH payment authorization or direct payment authorization) is a written agreement that allows a business or individual to electronically debit or credit a customer’s bank account through the Automated Clearing House (NACA) network.
Under NACHA Operating Rules (2024-2025 edition), any business initiating ACH debits — whether one-time or recurring — must obtain clear, readily understandable authorization from the customer and retain that record for at least two years after the last transaction (NACHA Rules §2.3.2.3).
Without a properly executed ACH authorization form, your transactions are considered unauthorized, exposing you to fines up to $500,000 per incident and mandatory return of funds.
| Type | Use Case | NACHA Code |
|---|---|---|
| PPD (Prearranged Payment and Deposit) | Consumer recurring or one-time debits (most common for B2C) | PPD |
| CCD (Corporate Credit or Debit) | Business-to-business payments | CCD |
| WEB (Internet-Initiated) | Online forms, e-signatures, checkout pages | WEB |
| TEL (Telephone-Initiated) | Verbal authorization over recorded phone call | TEL |
The free templates below cover PPD and WEB entries — the two most popular for small and medium businesses in 2025.
I designed this template to be attorney-vetted, NACHA-compliant, and simple enough for non-lawyers to customize in under 10 minutes.

Here is the core authorization language I use in every client template (and that is included in the free download):
“I (we) authorize [Your Company Name] to electronically debit my (our) account indicated below … for the amount(s) listed on invoices/statements on or after the due date(s) indicated. This authorization applies to both one-time and recurring payments until I (we) revoke it in writing or via recorded phone call. I (we) understand I (we) have the right to stop payment and receive a refund of any unauthorized debit by notifying my (our) financial institution at least three business days before the scheduled debit date.”

From my decade-plus reviewing returned ACH items:
Many clients need separate recurring language because NACHA imposes stricter rules on ongoing debits.
I’ve included a dedicated recurring ACH payment authorization form template that contains:

| Mistake | Return Code | How to Prevent |
|---|---|---|
| No signed authorization on file | R07 | Use this free template + store forever |
| Illegible routing number | R03/R04 | Require customer to attach voided check or use Plaid verification |
| Customer claims unauthorized after 60 days | R10 | Send confirmation email + keep delivery receipt |
Do I need a new ACH form every year?
No. A properly executed authorization remains valid until revoked (NACHA Rules §3.11). However, many businesses send annual re-authorization reminders to reduce fraud claims.
Can I use an online checkbox instead of a signed PDF?
Yes — WEB entries allow electronic records and signatures that meet ESIGN Act standards (15 U.S.C. §7001). The template is fully compatible with online checkout flows.
Is a voided check required?
Not legally required, but strongly recommended for accuracy. The template includes a space to attach one.
