WMS inventory: keeping the system's count equal to the shelf

Published , updated

WMS inventory is the system's belief about what is in the building and where, and it is only worth having if it matches the shelf. The belief is built from scans: a receipt scanned in, a putaway scanned to a location, a pick scanned out, a count scanned against the location. Every unscanned move is a place where the record and the shelf drift apart. WMS tracking is the same record read the other way, the history of a unit or a lot from the door it came in to the order it left on, which is what a client asks for when a customer complains. This page covers what the wms scanner must capture, what tracking has to answer and how the count program keeps the two honest.

What the scanner captures at each step

At receiving, the item barcode and the quantity against the advance notice, and the lot or expiry where the client controls them. At putaway, the item and the location it went to, confirmed by scanning the location label. At picking, the location and the item, so the system knows the pick came from where it directed. At packing, the order and each item into it. At shipping, the carrier label to the order. Five scans, and the barcode WMS guide on this site walks each of them, because a WMS with one of them keyed instead of scanned has a hole the inventory falls through.

WMS tracking: the history a client will ask for

A client's customer says the order was short, or the wrong item, or an expired lot. WMS tracking answers with the record: which receipt the unit came from, which location it sat in, who picked it and when, which order it shipped on. Lot tracking adds the ability to find every unit of a lot still in the building and every order it went out on, which a recall demands. None of it needs the operator to remember anything, provided the scans were made; all of it is impossible if they were not.

Cycle counts and what a discrepancy means

The count program is the test of the record: a few locations counted every day, scanned against what the system expects, so every location is visited on a cycle rather than once a year. Inventory accuracy is the share of counted locations that agree, and the reports worksheet on this site computes it from the counts you enter. A discrepancy is a signal, not a correction: the operator finds which unscanned move caused it before adjusting the count, or the same drift returns next cycle. Pickpathly Pro keeps the weekly accuracy figure per client on the record so a slipping trend shows early.

Questions people ask about wms inventory

What is WMS inventory?

The quantity and location of every unit as the warehouse system records it, built from scans at receiving, putaway, picking, packing and shipping. It is only as true as the scans that feed it.

What does a WMS scanner need to read?

The item barcode, the location label, the order and the carrier label, plus lot or expiry where the client controls them. A handheld or wearable scanner tied to the WMS captures each move as it happens.

How often should inventory be cycle counted?

A few locations every working day so that every location is counted on a cycle, fast movers more often. The operator sets the cycle from its own accuracy figure; this site publishes no target rate.
