Recurring ACH is the bank-account equivalent of card recurring payments. Instead of charging a credit or debit card, the merchant initiates a direct withdrawal from the customer's checking account through the U.S. ACH network. For high-value subscriptions and B2B contexts, ACH is often the preferred rail because it's dramatically cheaper than cards.
How recurring ACH works
- Customer authorization. At signup, the customer provides bank account and routing numbers and authorizes recurring withdrawals (legally required under NACHA rules).
- Pre-note verification. Many processors run a $0 test transaction to verify the account before the first real charge.
- Scheduled withdrawal. On the billing date, the merchant submits an ACH debit. Funds typically settle in 1–3 business days.
- Returns and reversals. If the account has insufficient funds, is closed, or the customer disputes, the bank issues a return code. The merchant handles like any payment failure.
ACH vs. card recurring
- Cost. ACH typically costs $0.25–$1.50 per transaction; cards cost 2.5–3.5% of transaction value. For a $200 subscription, ACH is ~$0.50 vs. $5–7 for cards — a 90% savings.
- Speed. Card charges settle in 1–2 business days; ACH settles in 1–3 days. For most subscription businesses the difference is negligible.
- Failure rate. ACH has lower decline rates than cards (no expiration issue) but higher dispute rates if the customer contests after settlement.
- Adoption. ACH is U.S.-only and requires bank account data; cards work globally and are easier for customers to provide.
When to offer ACH
ACH makes sense when:
- Transaction value is high. Card fees on a $300 subscription cost $9; ACH costs cents.
- B2B subscriptions. Business customers expect ACH for larger invoices.
- Long-tenured customers. Once an ACH authorization is in place, retention improves because there's no card-expiration churn.
- U.S.-only customer base. ACH doesn't help if you sell internationally.
Watch outs
ACH disputes (called "returns") have a 60-day window in some categories — meaning a customer can reverse a charge two months after it settled. Build dispute response into your operations. Also, NACHA compliance requires explicit authorization records; treat ACH onboarding as a legal process, not just a UX step.
