# ACH Debit and Recurring Billing

> How ACH debit pull payments power recurring billing in the US (subscriptions, memberships, and utilities) and how they compare with instant-rail alternatives.

When a US business collects a recurring payment from a customer’s bank account (a subscription, a membership, a monthly utility bill), it usually uses an **ACH debit**. This is the *pull* side of the ACH network: with the customer’s authorisation, the business pulls the money on a schedule. This page explains how ACH debit works for recurring billing and how it compares with newer instant-rail approaches.

<Note>
  ACH debit is a *pull* payment, where the business collects, rather than the customer sending. For the general concept, see [push vs. pull payments](/platform-overview/payment-concepts/push-vs-pull). For the push side of ACH, see [ACH credit transfers](/platform-overview/payment-concepts/ach-credit).

## How ACH debit works for recurring billing

<Steps>
  <Step title="Customer authorises the debit">
    The customer gives the business permission to debit their account, for example by agreeing to terms at signup and providing their bank account and routing numbers.
  </Step>

  <Step title="Business initiates each debit">
    On the agreed schedule, the business submits an ACH debit to pull the payment. Because ACH is batch-based, these are processed in windows rather than instantly.
  </Step>

  <Step title="Funds settle">
    The payment settles over standard ACH (typically 1–3 business days) or same-day ACH for eligible, time-sensitive collections.
  </Step>

  <Step title="Handling returns">
    If a payment fails (for example, insufficient funds), ACH provides a return process. This reversibility is part of what makes ACH debit workable for recurring billing.

  <Card title="Low cost at volume" icon="circle-dollar-to-slot">
    ACH is inexpensive per payment, which matters when you are billing many customers every month.

  <Card title="Familiar and widely supported" icon="building-columns">
    Almost every US bank account can be debited via ACH, so it reaches nearly all customers.

  <Card title="Built-in returns" icon="rotate-left">
    The return process gives a way to handle failed or disputed debits, which is useful for ongoing billing relationships.

    Fixed subscriptions and memberships map neatly onto scheduled ACH debits.

## ACH debit vs. instant-rail recurring approaches

The instant rails (FedNow and RTP) are **credit-push** by design; the sender initiates. That means they do not offer a traditional pull debit in the way ACH does. Newer approaches such as request-for-payment (where the business asks and the customer approves) and variable recurring payments aim to bring instant rails into recurring billing, but adoption is still early.

|                   | **ACH debit**                        | **Instant-rail recurring (emerging)**        |
| ----------------- | ------------------------------------ | -------------------------------------------- |
| **Model**         | Pull; business debits the account    | Push or request-for-payment; sender approves |
| **Speed**         | Batch; 1–3 days (or same-day)        | Instant                                      |
| **Reversibility** | Returns process available            | Irrevocable once sent                        |
| **Maturity**      | Well-established, ubiquitous         | Early and growing                            |
| **Best for**      | Standard subscriptions and utilities | Time-sensitive or high-certainty collections |

<Note>
  Because instant payments are credit-push and irrevocable, they change how recurring billing works: the customer approves each payment or a variable agreement, rather than the business simply pulling. Expect this area to evolve over the next few years.
</Note>

<Tip>
  For most US recurring billing today, ACH debit remains the practical default: cheap, familiar, and supported everywhere. Keep an eye on request-for-payment and variable recurring payments as instant-rail options mature.
