We are able to change a payment method on a purchase order as long as an order has not already been finalized. Once an order has been completed and payment has been issued, no payment changes can be made. If you need to request a payment method change please create a ticket with our Customer Support team here.
Please note, if you make the request prior to order finalization, but received an answer to your request after order finalization, the payment method cannot be changed. If you have already shipped your purchase order and need the payment method changed, please call into our Customer Support team to handle that request. You can reach us at (206) 523-2273.
