PO Number
A unique identifier for matching and tracking. Include versioning for change orders and references to master agreements or contracts.
Electronic purchase orders speed processing, reduce manual errors, and preserve an audit trail. They can be enforceable under federal and state e-signature laws when they meet the ESIGN Act and UETA standards for intent, consent, attribution, and retention (15 U.S.C. ch. 96; UETA). Digital routing also supports consistent approvals and easier archival.
Typical participants include procurement, finance, receiving, and external suppliers across mid-market and enterprise organizations.
Roles vary by organization size; some combine procurement and AP duties while larger teams separate approval and payment functions.
Procurement managers prepare and authorize purchase orders, confirm vendor details, and enforce contract terms. They ensure the PO matches negotiated pricing and delivery dates and coordinate internal approvals when required.
Accounts payable personnel match vendor invoices to the issued PO and receiving reports. They verify payment terms and process invoices for payment, maintaining records for tax and audit purposes.
