See the recorded product workflowWhat this document helps you record
A purchase order reference register traces a client-issued reference back to its actual document and scope. It differs from an invoice numbering plan: the client reference is supplied evidence, while the invoice number identifies your own billing document. Do not replace one with the other.
Record the exact reference, source version, client entity and the approved scope it relates to. Preserve actual recipient requirements for formatting and submission. A length or character check can expose a copying error, but it cannot establish authenticity, authority or remaining purchase-order value.
The fictional register retains PO-2026/001 with its reviewed source and an entered 20-character limit. The companion check finds 11 characters under its explicit example policy. The billing owner still matches the actual client rule and approved service scope before using the reference.

How to complete the template
Capture the source without rewriting it
Record the exact reference, client entity, document version, date and source evidence. Link the approved service scope and identify unresolved authority questions.
Check the actual format requirements
Retain the recipient's stated limit and permitted character policy. Compare any copied reference with the original; resolve mismatches through the authorized process.
Match the billing handover
Reference the approved draft and eligible scope. Verify any required value or submission check separately and retain the decision and reviewer.

Avoid this
Treating a format match as purchase-order approval
A correctly shaped reference can still belong to the wrong scope or an unverified document. Check actual authority and identity.
Avoid this
Silently removing spaces or punctuation
A changed reference may no longer match the client's record. Preserve the original and document an authorized correction.

Questions people usually have before changing the workflow.
Does the register track available purchase-order value automatically?
No. Record and reconcile actual approved value, prior use and remaining authority separately where required.
Can one invoice reference several purchase orders?
Follow actual recipient requirements and map scope and lines explicitly. The companion checker reviews one reference at a time.
Does this replace the invoice number?
No. Retain the unique invoice ID and the client reference as separate fields.
