How do you reduce picking errors, and what is a good picking accuracy rate?

Most eCommerce warehouses run at 97–99% picking accuracy. Best-in-class operations hit 99.9% or better. Here's how to measure yours, what each error actually costs, and the changes that close the gap.

Industry norm: 97–99% accurate; best-in-class 99.9%+

Measure it: mis-picks ÷ order lines picked

A 1% error rate on 1,000 orders a day is 10 wrong parcels daily

Barcode validation is the single biggest fix

StoreFeeder customers average 99.95%

StoreFeeder rated 4.8 out of 5 on Trustpilot

We were picking 28 orders an hour, now we're rolling along quite comfortably at 45, and we know in busy times we can achieve 55, 60, comfortably and safely. StoreFeeder helped this situation because it automated a lot of processes for us. It is just purely scan and pack.

Why picking accuracy slips, even in well-run warehouses

Paper lists and memory

Pickers read a sheet, find the location from experience and nothing checks the item in hand.

Similar SKUs and sizes

Variants that look alike get swapped, and the mistake isn't caught until the customer opens the box.

Peak and new staff

Temps and new starters don't have the product knowledge the process quietly depends on.

How to measure and improve picking accuracy

Step 1: Measure

Work out your real error rate

Count mis-picks (wrong item, wrong quantity, missed item) as a share of order lines over a month. Include errors found at packing, not just those reported by customers. Anything under 99.5% is costing you money.

✓ Mis-picks ÷ lines picked, per month ✓ Include errors caught at the bench ✓ Track by picker and by zone

Step 2: Cost it

Put a price on each mistake

A wrong parcel costs the outbound postage, return postage, a replacement pick and pack, extra packaging and the refund admin, before any lost feedback. Most UK sellers land at £15–£30 per error.

✓ Outbound and return postage ✓ Second pick, pack and packaging ✓ Refund handling and feedback damage

Step 3: Validate

Scan every pick against the order

Barcode validation is the change that moves the number. The picker scans the location, then the product; the app rejects anything that doesn't match. Accuracy stops depending on experience.

✓ Location and product scan on every line ✓ Wrong items rejected on the spot ✓ Four validation levels to suit each picker

Step 4: Route

Reduce fatigue with better routes

Tired pickers make mistakes. Optimised pick routes and consolidated pickwaves cut the walking, so pickers handle more lines with less effort and fewer slips.

✓ Shortest route through the warehouse ✓ Pickwaves group orders by location ✓ Fewer steps, fewer errors late in the shift
