Inventory counts and shrink: a routine staff will keep

The POS says there are twelve on hand. The shelf has seven. Somebody changes the number to seven, nobody writes down why, and next month the same thing happens with a different item. In many small shops we work with, that is what inventory control looks like. The count happens once a year, the gap gets written off, and shrink stays a single line on the tax return instead of something the team can see and fix.

Why the numbers drift

Shrink is the gap between what your system says you have and what is actually there. Theft is part of it, but in small businesses it is rarely the biggest part. Most of the gap comes from ordinary process leaks:

• Receiving. A case of 24 arrives with 22 inside, and someone receives the full case because the packing slip says 24.
• Wrong item rung. A cashier scans one flavor and hands over another, so one count runs high and the other runs low.
• Damage and spoilage. Broken or expired product goes in the dumpster without being recorded.
• Transfers and samples. Stock moves to another location, the back office or a sales rep's car, and the system never hears about it.
• Unrecorded returns. A returned item goes back on the shelf, or back to the vendor, with no matching entry.

Each of these is small. Together they make the on-hand number untrustworthy, and once staff stop trusting it, they stop using it. Reorders turn into walking the shelves and guessing. Online orders get sold that nobody can fill.

Swap the annual count for a weekly cycle count

A full wall-to-wall count once a year tells you how much went missing. It does not tell you when or why, because twelve months of small errors are buried in one number. We move most clients to cycle counting: a small set of items counted every week, on a fixed day, by a named person.

A workable starting routine looks like this:

• Pick 20 to 40 items a week. Start with your highest value and fastest moving products, plus anything that was adjusted last month.
• Count before open or after close. Counting while customers are buying creates its own errors.
• Count blind. The counter sees the item list, not the expected quantity. When people know the number they are supposed to find, they tend to find it.
• Enter counts the same day. A count sheet sitting in a drawer until Friday is already out of date.
• Rotate through everything. Top items come up every few weeks. Slower items come up once a quarter.

Most stores need 30 to 60 minutes a week for this. It replaces the dreaded annual count with a habit small enough that nobody has to schedule overtime for it.

Give every adjustment a reason

The most useful change is also the least technical. Every inventory adjustment gets a reason code. Keep the list short, five or six choices at most: damaged, expired, receiving error, found stock, transfer, unknown. Most POS systems support reason codes or a notes field on adjustments. If yours does not, a shared log works until you outgrow it.

After a month, the reasons tell a story. If most of the gap is receiving errors, the fix is at the back door, not the register. If one category keeps landing in unknown, that is where you look closer. Without reasons, every variance looks like theft, and that assumption sours a team fast.

We also set a threshold for review. Small variances on low value items get adjusted and logged. Anything above a set dollar amount, or any item that misses two counts in a row, gets a second count by a different person before anyone touches the number.

Fix receiving before you blame the floor

Receiving is where we see small retailers lose the most accuracy, and it is the easiest place to fix. Three habits cover most of it:

• Count against the slip first. The shipment is checked against the packing slip before it is received into the system, not after.
• Receive partials as partials. Shorts and damages get noted on the slip and passed to whoever handles vendor credits.
• One owner per shift. A named person handles receiving on each shift, so the step is never assumed to be someone else's job.

Once receiving is clean, the counts on the floor start to mean something. Until then, the floor takes the blame for errors made at the dock.

The part that makes it stick

A count routine is easy to write down. Getting staff to run it every week, honestly, is the real project. Inventory work carries a risk that most process changes do not: people hear "shrink" and think "they think we are stealing." If the rollout starts there, counts get rushed and numbers get nudged to look clean.

So we spend more of our time on the people side than the system side:

• Lead with the reason. The goal is to stop promising items that are not there and to reorder before the shelf is empty. Missed sales and frustrated customers make everyone's shift harder. That framing is true, and it lands.
• Make counting a named job. One person owns the weekly count, with a backup. It goes on the schedule like any other shift task.
• Share the results. A short weekly note or a whiteboard in the back room: items counted, accuracy rate, top adjustment reasons. When accuracy climbs, say so out loud.
• Run the first few counts together. We count alongside staff for the first two or three weeks, fix the steps that do not match how the store really works, and adjust the item list.
• Keep it boring. Same day, same time, same sheet. Routines survive when they stop feeling like an event.

We check in again after the first full rotation, usually six to eight weeks in. By then the patterns are clear. That is the right time to tighten thresholds or add a small connection between systems, such as sending count results to your accounting system without anyone re-keying them.

Signs your inventory needs attention

If a few of these sound familiar, a steady count routine will likely pay for itself within a quarter:

• Staff check the shelf instead of the system before telling a customer you have something.
• You take online orders you cannot fill.
• The annual count ends in a write-off that nobody can explain.
• Adjustments happen with no record of who made them or why.
• Reorders depend on one person walking the aisles.

Where to start this week

Pick ten of your best selling items. Count them blind before you open on Monday, then compare each count to what the system says. Write down the gap and a best guess at the cause. That short list is your baseline, and it usually points straight at the first fix.
