What is eProcurement?

Home > Glossary > eProcurement

eProcurement is the digital management of business purchasing processes such as supplier catalogs, requisitions, approvals, purchase orders, invoicing, and spend controls. It connects buyers, procurement systems, suppliers, and ecommerce or marketplace platforms.

An eProcurement system manages purchasing from the buyer’s side: approved suppliers, catalogs, requisitions, budgets, approvals, purchase orders, receiving, and often invoicing. It differs from a supplier’s B2B ecommerce portal, which is designed around the seller’s catalog and commercial processes. Enterprise transactions often connect the two through PunchOut, cXML, OCI, EDI, or APIs.

Typical eProcurement capabilities include:

• Supplier and catalog management with approved purchasing sources.

• Requisitions and approval workflows tied to budgets, departments, and cost centers.

• Purchase-order creation and transmission to suppliers.

• Spend visibility, invoice matching, and policy controls across organizational purchasing.

For suppliers, supporting eProcurement matters because large customers may require buyers to purchase through corporate systems rather than a public storefront. The ecommerce challenge is to preserve a strong catalog and ordering experience while fitting into the customer’s controlled procurement workflow. Integration quality becomes a commercial requirement, not only an IT concern.

Example: An enterprise employee chooses an approved supplier through the company procurement system, creates a requisition, obtains manager approval, and issues a purchase order without purchasing outside corporate policy.
