We do, but we strongly recommend the use of Purchase Orders ONLY for larger value orders.
As a small company, we have no dedicated finance staff member and purchase orders take up a significant amount of time to complete. As a result we apply an administrative fee and will review discounts available on a case by case basis, particularly for very low value orders.
This is an eCommerce site built on the tools that help automate pricing, order acceptance, payment and fraud prevention so anything that requires significant manual intervention will result in less desirable pricing and/or final cost to offset the cost of providing such a service. Thank-you for your understanding.
