Enter your pick volume and current checkpoints
Add the number of order lines picked per period, how many validation checkpoints you currently use (SKU scan, quantity check, location check, final verification), and your historical pick-error rate.

How it works
We apply a diminishing-returns reduction model
Each validation checkpoint cuts the remaining error rate by roughly 35%, compounding across checkpoints, so the error rate falls fastest with the first checkpoint and more slowly with each additional one.
Get an estimated new error rate and errors avoided
The result shows your estimated new error rate, the percentage reduction achieved, and roughly how many pick errors that translates to avoiding per period.

Frequently asked questions
Does PickError Guard do live barcode scanning or connect to my WMS?
No. PickError Guard computes results only from the numbers you enter — it does not perform live barcode scanning, connect to a warehouse management system, or read real pick data. It is a planning calculator for estimating the impact of adding validation steps.
Why does each checkpoint reduce errors by a diminishing amount?
In practice, additional validation steps catch a shrinking share of the errors that remain after earlier steps already caught the more obvious mistakes, so the model applies a consistent ~35% cut to whatever error rate is left rather than a flat percentage of the original rate.
What counts as a validation checkpoint?
Common examples are a SKU barcode scan-confirm, a quantity check, a bin/location check, and a final verification scan before packing. Count only steps that are actually enforced in your process today.
Where do I get my historical pick-error rate?
Use return/mis-ship data, customer complaints, or a recent cycle-count audit to approximate your current error rate. Even a rough estimate is more useful than skipping the input.
Is this a guaranteed error rate after adding checkpoints?
No. It is an estimate based on a general diminishing-returns pattern seen in pick validation, useful for planning which checkpoints to prioritize, not a guaranteed outcome for your specific operation.
Can I use this for a single SKU or a whole warehouse?
Either — enter the order-line count and error rate for whatever scope you want to analyze, from a single pick zone to your entire operation.
