Illustrative example
A space detected without changing the source
- Original reference
- PO-2026/001
- Copied reference with trailing space
- 12 code points
- Reported mismatch
- Position 12 / U+0020
- Next review
- Actual source and recipient policy
- Authority still required
- Correct draft mapping and permitted correction process
Fictional example policy, not universal recipient requirements.
See the recorded product workflowDecisions to make before billing
A purchase-order reference check starts with the actual client source and recipient requirements. Preserve the text exactly before checking for copying mistakes. An automatic trim or punctuation change can hide a mismatch rather than resolve it.
The companion tool counts Unicode code points in the entered text and applies an explicit example policy allowing ASCII letters, digits, hyphens, underscores and slashes. It compares an entered length limit without claiming that every client uses those rules. Different limits based on bytes, visual characters or system behavior need their actual method checked separately.
The fictional reference PO-2026/001 has 11 characters. Adding a trailing space creates a twelfth character outside the example policy. The next step is source and recipient verification, not silently editing a live billing record or treating a format pass as approval to charge.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Preserve original text and context
Record reference, source version, client entity and approved scope. Check whether it is the requested reference field, not an invoice number or unrelated account ID.
Apply the actual stated rules
Retain the client's limit, counting method and permitted characters. Use the example-policy tool only where its method fits, then inspect reported positions against the source.
Resolve mismatch under authority
Confirm any correction with the authorized source and retain the decision. Check draft line mapping, required value authority and appropriate issued-document correction process separately.

Avoid this
Accepting a shape without checking identity
A well-formed reference can belong to another entity or scope. The format result proves neither.
Avoid this
Assuming all length measures match
Bytes, code points and visual grapheme clusters can differ. Record the recipient's actual counting rule.

Questions people usually have before changing the workflow.
Does the checker normalize Unicode or case?
No. It preserves exact text and reports mismatches under the fixed policy.
Can an unsupported character be valid for my client?
Yes. The actual recipient may permit a different character set. Check its requirements before changing anything.
Should a corrected reference overwrite an issued document?
Use the approved correction process and required evidence. This guide does not grant editing authority.
