ACH vs card: choose the payment path before a large invoice
Large invoices can lose meaningful cash to card fees, but ACH can have slower timing and return risk. Choose the payment path before sending the invoice.
For a large invoice, the payment method can change both net payout and cash timing. Compare card fees, ACH limits, settlement timing, client convenience, and your margin before deciding what payment options to show on the invoice.
Compare net payout before convenience
A card payment may be faster for the client and simpler to collect, but the percentage fee can be material on a large balance. Run the expected fee against the invoice total before treating the full amount as available cash.
Check timing, limits, and return risk
ACH payments may cost less, but bank limits, verification, settlement timing, failed pulls, and return windows can affect when cash is safe to spend. Match the method to how soon you need materials, payroll, or subcontractor payments.
Write payment terms cautiously
State accepted methods, due dates, deposits, late-payment terms, and who pays any allowed fee before sending the invoice. Confirm platform, card-network, ACH authorization, state, and contract rules before adding surcharges or restricting payment choices.
