We require a valid Credit Card on file for all active accounts, but that is primarily for insurance/incidental purposes. How you actually pay for your rental is up to you – we accept check, cash, wire transfer, & all major credit cards. Once an order is completed and checked in, we will send you the final invoice listing the amount owed and the payment due date. Most established accounts are Net-30, but newer accounts may be COD or have shorter terms (Net-7, Net-15, etc.). If payment is not received by the invoice due date, we reserve the right to charge the card on file.
