A wrong item in the box costs far more than the item: a refund or replacement, return shipping, a support email and sometimes a bad review. For a small shop, a picking error rate of even one in a hundred orders adds up fast. The good news is that most errors have a handful of causes, and each has a simple fix.
Why picking errors happen
- Look-alikes stored together: two sizes or colours of the same product in one bin.
- No clear location: the picker has to remember or search, and grabs the nearest match.
- Quantities missed: “2” on a busy list is easy to read as one.
- Interruptions: a picker loses their place and skips or repeats a line.
- No final check: nobody compares the box with the order before sealing it.
7 ways to reduce picking errors
1. Give every product a labelled home
If the picker has to search, they’ll eventually pick the wrong thing. Give every bin a short label in walking order and record which products live there. See how to set up bin locations.
2. Keep look-alikes apart
Store sizes and colours of the same product in different bins, ideally not next to each other. It feels less tidy than keeping a product family together, but it removes the most common mix-up.
3. One product per bin, wherever you can
Mixed bins are where most mis-picks happen. Give your best sellers their own bins first; if slow sellers must share, make sure they look nothing alike.
4. Make quantities impossible to miss
On paper, write quantities large and bold, or circle anything above one. On screen, show the quantity right next to the location, not at the end of the line.
5. Use a pick list that tracks progress
A list with a tick per line, sorted in walking order, means an interrupted picker knows exactly where to resume. Our pick list guide has a free template.
6. Check with a barcode scan
Scanning each item’s barcode as you pick catches the wrong size or colour before it reaches the box. Most phones can scan with their camera, so you don’t need special hardware to start.
7. Check the order before you seal the box
Compare the box with the order or packing slip: item count, then each line. Ten seconds per order catches what got past the other steps. Note every error you find and why it happened, then fix the cause, for example by moving a look-alike to another bin.
Measure it
Keep a simple count: orders shipped, and orders with an error (found at packing or reported by a customer). Divide one by the other each month. If the number isn’t going down, look at which products appear in the errors; it’s usually the same few.
How pickBlink helps
pickBlink shows each item’s bin lit up on a photo of your actual shelf, with the quantity on the bin, so pickers see where to go instead of decoding a label. Items are ticked off in walking order, you can scan barcodes with the phone’s camera to check each one, and pickBlink warns you before completing an order with items not yet ticked off.
