You can decide to charge the Stripe processing fee to your clients or not. ACH transfers on Stripe cost 0.80%, capped at $5 with no monthly fees or verification fees. For instance, a payment of $100 incurs a $0.80 fee, but any payments above $625 also incur a maximum of $5 fee. This option is cheaper for your clients and can be useful if you routinely invoice them large amounts on a recurring basis. Also, BQE does not charge any extra fees for using ACH payments in CORE.
