ACH built for recurring billing and high-ticket transactions.
Bank-to-bank ACH is one of the lowest-cost payment rails available — and on high-ticket or recurring transactions, the economics are hard to ignore. BIG's ACH stack integrates Plaid for fast account verification, handles NACHA file generation and return management, and pushes settlement updates straight into your ledger.
ACH that just works
Plaid-powered account linkage, NACHA-compliant origination, recurring billing automation, and bank-level security — all in a single integration.
Why operators choose ACH with BIG.
Lower cost than card networks
ACH runs on bank rails, not card networks — the per-transaction cost is a fraction of what you'd pay on credit or debit. The savings compound fast on recurring billing and large-ticket transactions.
No chargebacks, no card-network risk
ACH disputes go through a regulated NACHA return-code framework — predictable, capped, and far less painful than card chargebacks.
Built for recurring at scale
Tokenized account linkage, auto-retry logic for returns, and webhook notifications on every state change. Set it up once and it runs.
Real 5-star reviews on Google. No edits, no incentives — just merchants who’ve been told no everywhere else.
