How to Improve Inventory Accuracy in Warehouses (The Real-World Way)
Inventory accuracy isn’t the most exciting topic in supply chain, but it might be the most important. If you've ever had to explain a missing pallet, a stockout that shouldn't have happened, or a shipment that somehow ended up going to the wrong customer, you know exactly what I mean.
After more than 25 years working in warehouse and supply chain operations, I've learned that it doesn’t take a fancy system or a massive budget to tighten things up. It just takes paying attention to the right areas, getting your team involved, and doing the basics well.
Here’s what’s worked for me over the years:
1. Make Cycle Counts Part of the Routine
Doing a big once-a-year count might check a box, but it won’t fix your problems. What really works is setting up cycle counts that run weekly or monthly, depending on the item’s movement or value. It spreads the work out, keeps errors from piling up, and helps your team stay close to what’s actually on the shelves.
At one point, we reached 99.9% inventory accuracy across 20 warehouses, and the biggest reason was sticking to a clean, simple cycle count process.
2. Get Receiving Right from the Start
A lot of problems begin before product even hits the shelves. If your receiving process is off—wrong quantity, missed items, bad labeling—you’re going to spend a lot of time fixing it later. I've found that clear SOPs, good training, and basic barcode scanning can make a huge difference here.
Fix it at the dock so it doesn’t become a bigger issue later on.
3. Watch Your Shipping Process Closely
Shipping mistakes can throw everything off. I've seen situations where the right item was picked but the wrong label got slapped on. Or someone grabbed the right label but pulled from the wrong bin. Every one of those mistakes not only causes a return or a frustrated customer, but it also messes with your counts.
What’s helped me most is treating shipping like a final quality check. Use simple checklists, scanners, or even two-person verification when needed. A few extra seconds at the dock can save hours of cleanup later.
4. Your People Matter More Than Your Systems
I’ve worked with all kinds of tools—from expensive WMS platforms to spreadsheets and Smartsheet trackers. The biggest difference isn’t the software. It’s the people using it.
When your team understands the impact of their work, takes pride in getting things right, and knows they have support when mistakes happen, they do better work. Teach the “why,” not just the “how.” Recognize the wins. Give people a reason to care.
5. Use Data, but Keep It Simple
You don’t need a full analytics team to find useful trends. I’ve used Power BI dashboards, Excel reports, and even whiteboards to track where errors happen most. Look for:
-
Items that go off-count often
-
Problematic storage locations
-
Shifts where accuracy slips
Once you spot the patterns, you can start fixing the root causes instead of chasing symptoms.
6. Connect Accuracy to the Bigger Picture
If accuracy is just a number on a report, people won’t care much. But if they understand that a wrong count can mean a late shipment, a lost customer, or a coworker staying late to fix it, the mindset starts to shift.
Make it real. Talk about what’s at stake. Let your team see how their actions keep things running.
Getting to great inventory accuracy isn’t about fancy tech or chasing perfection. It’s about building a culture where people care, creating processes that are clear and doable, and using the tools you already have to stay on top of things.
You don’t need to do everything at once. Pick one area, make it better, and go from there. You’ll be surprised how fast it adds up.
