Content about eCheck payments (ACH debits in the U.S.) for high-risk merchants (iGaming/betting, FX/CFD, adult, nutraceuticals, crypto). We cover how eChecks work (CNP WEB debits, 6/8-digit BIN isn’t used), bank-account verification (micro-deposits, open-banking APIs, NACHA WEB Account Validation Rule), limits/velocity ladders, return windows & codes (e.g., R01 NSF, R02 acct closed, R03 no acct, R10 unauthorized), when re-initiation is allowed, refunds vs reversals, cut-off times and T+ settlement, reconciliation/webhooks, and how ODFI risk appetite affects onboarding for high-risk verticals. Regional analogs: EFT (Canada), SEPA Direct Debit (EU/EEA) with different mandates and dispute rights.
Typical use cases
One-off pay-ins and wallet/account funding
Free trial → subscription (CIT→MIT) with ACH fallback to reduce card fees/declines
Chargeback exposure vs cards (no chargebacks, but NACHA returns/claims) and how to design flows to lower R10s
Best-practice checklist
Enforce account validation before first WEB debit; store consent/micro-deposit evidence
Apply velocity rules and amount caps by KYC tier; delay access until funds clear
Build return-handling (auto-refunds, retry policies within NACHA limits)
Keep PCI DSS minimal (no PAN) but secure PII; log consent per SEC code (WEB/TEL/PPD/CCD)
