Accounts payable support may assemble records, check completeness, apply an approved calculation, and route exceptions, but it must not create vendor facts, approve invoices or payments, change bank details, waive policy, interpret contracts or tax rules, or attest that unsupported work is complete.

A reproducible invoice dispute routing record at checkpoint 1 retains source identifiers, receipt time, preparer, state, reason code, evidence link, reviewer, and correction history. Missing values remain unavailable rather than becoming favorable assumptions. Reviewers compare system values with retained evidence, record disagreements, assign repairs, and preserve prior values. The process owner approves thresholds based on risk, systems, contracts, jurisdiction, volume, and supplier expectations; no universal target is implied.
