What is an inventory audit?

An inventory audit checks two things: do the counts match reality, and can the process that produces them be trusted? The first is verification: physical counts compared against records, in full or by sample. The second is the part teams forget: an auditor also looks at how receiving is recorded, who can adjust counts, whether adjustments carry reasons and names, and whether cutoff is clean (goods received on March 31 belong in March's inventory, not April's). External audits arrive with financial statements, lender requirements, acquisitions, and insurance claims. Internal audits are the same discipline run on your own schedule, usually as an annual full count plus the continuous verification of cycle counting. What auditors actually ask for is a useful checklist to run against your own system: a complete item list with quantities, locations, and values; movement history with timestamps and users; documentation for adjustments and write-offs; receiving records tied to POs; and evidence that counts happen on a schedule. An operation that can produce those in minutes has a calm audit. An operation reconstructing them from spreadsheet tabs and email threads has a long week. Where teams trip: treating audit-readiness as a scramble before the auditor lands. The cheap version is structural: record movements as they happen, require cause codes on adjustments, and keep the trail by default.
