Running an Annual Physical Inventory Count Without Chaos

A full physical count freezes operations and counts every SKU on one day, which is disruptive but gives you one clean number to reconcile against the general ledger. Cycle counting spreads counts across the year, a subset of SKUs at a time, so operations never fully stop, but it only works if you're disciplined about counting every location on a real rotation, not just the easy ones. Most small and mid-sized companies run cycle counts through the year for early warning and still do one full annual count near year-end to produce the number their auditor or lender actually relies on.

The person who counts inventory should not be the same person who adjusts the books to match the count. If your warehouse lead both counts the shelf and posts the adjusting entry, an error, or a deliberate one, never gets a second set of eyes. Have warehouse staff do the physical count in pairs (one counts, one records), and have someone in finance who wasn't on the floor that day post the resulting adjustment after reviewing the variance report line by line.

Freeze receiving and shipping for the count window, or clearly cut off and segregate any inventory in transit so it isn't double-counted or missed entirely. Print count sheets by location rather than relying only on a scanner app, since a second physical method catches scanner errors. Recount any SKU where the physical count differs from the system count by more than a small tolerance you set in advance, before you accept the variance as real.

• Freeze or clearly cut off receiving and shipping during the count window
• Count in pairs: one counts, one records, independently where possible
• Recount any material variance before accepting it
• Have finance, not the counting team, post the final adjusting entry

A shrinkage number with no explanation reads as a control weakness even if the dollar amount is small. Break the variance into categories before you report it: known damage or spoilage written off during the year, receiving errors where the system quantity never matched what actually arrived, and unexplained loss, which is the category that should worry you most because it can mean theft. Gross margin by industry gives you a useful gut check here¹: if your unexplained shrinkage is eating meaningfully into a margin that should otherwise track your industry's typical range, that's worth escalating before your next count, not waiting to explain again next year.

If this year's count turned up a large unexplained variance, don't just book the adjustment and move on. Check whether receiving is verifying quantities against the purchase order before putting stock away, whether damaged goods are being written off as they happen instead of piling up and getting discovered only at count time, and whether your perpetual inventory system access lets warehouse staff make quantity adjustments without a second approval. Fixing the process that created the variance is worth more than getting a cleaner number next year by accident.

Keep the raw count sheets, not just the final reconciled number, along with a short memo explaining every material variance by category and who approved the adjusting entry. An auditor testing inventory will usually pick a sample of locations or SKUs and ask to trace them back to the original count sheet, so if that paper trail doesn't exist, the count itself becomes a finding regardless of how accurate the final number turned out to be. File this documentation with the same discipline you'd apply to any other year-end closing binder, since inventory is often one of the largest balance sheet accounts an auditor will test.
