We don't, but this works for many organizations that use Purchase Orders: Place the order and select "check by mail" as the payment method. Submit the order confirmation to your organization for approval and as soon as we receive your organization's check we will get your product right out. Others choose to use a personal credit card and get reimbursed by their organization later.
