ACH Billing
ACH billing moves money directly between bank accounts over the Automated Clearing House network — the same system behind direct deposit. For subscription businesses it matters for two reasons: transaction costs are a fraction of card fees, and bank accounts don’t expire, so recurring ACH payments fail far less often than card payments.
ACH billing is the practice of collecting payments by debiting a customer’s bank account directly through the Automated Clearing House (ACH) network, instead of charging a credit or debit card. It is widely used for recurring payments because fees are lower and bank accounts expire far less often than cards.
How ACH billing works
When a customer authorizes ACH billing, they share their bank routing and account numbers and consent to be debited. Each billing cycle, the merchant’s payment processor submits a debit request through the ACH network, which clears the transfer between the two banks — typically in 1–3 business days (same-day ACH is available at a premium).
- The customer authorizes the debit (a one-time mandate covering future recurring charges).
- The processor batches the debit request into the ACH network.
- The clearing house routes the request to the customer’s bank.
- Funds settle to the merchant’s account, usually within 1–3 business days.
ACH vs. credit card billing
The trade-off is speed and familiarity versus cost and reliability:
| ACH billing | Card billing | |
|---|---|---|
| Typical cost | ~0.5–1%, often capped ($0.25–$5) | ~2.9% + $0.30 |
| Settlement | 1–3 business days | Instant authorization, 1–2 day payout |
| Failure modes | Insufficient funds, closed account | Expiry, reissue, decline, fraud blocks |
| Recurring failure rate | Low — accounts rarely change | Higher — cards expire and get reissued |
| Chargeback window | 60 days (consumer accounts) | 120+ days |
Why ACH matters for subscriptions
For a recurring business, involuntary churn — subscribers lost to failed payments — is one of the largest silent revenue leaks. Expired and reissued cards are the leading cause. Because bank accounts don’t expire, ACH-billed subscribers fail far less often, which is why B2B SaaS and high-ticket subscriptions push customers toward ACH.
Most Shopify subscription volume still runs on cards through Shopify Payments, so the practical lever for merchants is not switching rails but recovering the card failures you do get. That is what dunning automation does — smart retries plus card-update requests before a subscription is lost.
Common ACH terms
- ACH debit — the merchant pulls funds from the customer’s account (how recurring billing works).
- ACH credit — the payer pushes funds out (e.g. payroll direct deposit).
- NSF return — a debit rejected for insufficient funds; the ACH equivalent of a card decline.
- Mandate — the customer’s stored authorization to debit their account on a schedule.
Häufig gestellte Fragen
What is ACH billing?
ACH billing collects a payment by debiting the customer’s bank account through the Automated Clearing House network rather than charging a card. The customer authorizes the debit once, and the merchant can then collect one-time or recurring payments directly from the account.
Is ACH billing safe?
Yes. ACH transfers run through a federally regulated network governed by Nacha rules, and consumers can dispute unauthorized debits for up to 60 days. Merchants must store bank details securely and keep the customer’s authorization on file.
How long does an ACH payment take?
Standard ACH debits settle in 1–3 business days. Same-day ACH exists at a higher fee. This is slower than a card authorization, which is why ACH failures (like insufficient funds) can surface days after the order.
Why do subscription businesses like ACH?
Fees are much lower than card fees, and bank accounts don’t expire the way cards do, so recurring ACH payments fail less often. Fewer failed payments means less involuntary churn.
