Payments

    ACH transfer

    An electronic bank-to-bank transfer over the US Automated Clearing House network.

    Definition

    Cheap (~$0.25 per transaction) but slow — 1–3 business days. Best for B2B invoices and large amounts where card fees would be punishing. Customers pay using their routing + account number.
