# Warehouse modernization: prepare the floor before the WMS

Test receiving, picking, and exceptions with the people doing the work.

Warehouse modernization starts with the accuracy of the work on the floor. Before selecting a warehouse management system, establish how goods are received, identified, located, picked, packed, and returned. Software should reflect those rules well enough for a new team member to follow them.

## Separate a warehouse problem from a data problem

A missed dispatch can have several causes: the item is in the wrong bin, the unit of measure is wrong, the order was never released, or a carrier label failed. Each cause calls for different work.

Walk one inbound delivery and one outbound order with the people responsible. Include an exception such as damaged stock, a short receipt, a substitute, or a customer return. Record where physical movement and system records diverge.

Choose consistent identifiers for products, locations, and handling units. A case of twelve and a single unit need an explicit relationship. Printing a barcode cannot resolve an incorrect quantity definition. Check existing supplier labels and customer requirements before deciding what to relabel.

## Demonstrate the difficult scan

[Microsoft's piece-picking documentation](https://learn.microsoft.com/en-us/dynamics365/supply-chain/warehousing/piece-picking-confirmation) illustrates how mobile confirmation can check inventory and incorporate quantities and units represented by barcodes. It is a platform example, not a recommendation that every warehouse needs that product.

For your own pilot, ask an operator to scan the correct item, the wrong item, an unreadable label, and a different pack size. Observe what happens next. Can the person correct the problem without inventing a workaround? Does the correction leave an understandable record?

Check the environment too. Wireless coverage, device handling, printer placement, charging, and label durability affect the daily process. Include the relevant equipment supplier or on-site team in that assessment; a software project alone cannot establish physical readiness.

## Use a floor-readiness worksheet

| Workflow | Demonstration to request | Evidence to keep |
| --- | --- | --- |
| Receiving | Receive a partial delivery and record damage | Expected versus received quantity |
| Putaway | Move goods to a valid location and reject an invalid one | Location and movement history |
| Picking | Scan a wrong item and a different pack size | Error handling and unit conversion |
| Packing | Split an order and produce the right dispatch records | Parcel-to-order relationship |
| Counting | Investigate a stock difference before adjustment | Approval and adjustment record |
| Returns | Separate saleable, damaged, and inspection stock | Disposition and availability update |
| Connectivity | Continue or pause safely when a device loses connection | Recovery procedure and reconciliation |

## Define inventory states before connecting channels

On-hand, reserved, damaged, quarantined, and available-to-sell quantities describe different things. Write down the calculation used for each sales channel. Decide which system owns stock movements and which systems consume that information.

An illustrative business may physically hold 100 units, reserve 20 for paid orders, and quarantine five. Publishing all 100 as available can create a promise the warehouse cannot fulfill. The correct available quantity depends on the business's reservation and stock policies; it should not be guessed independently by each integration.

Pilot one zone, product family, or order flow with enough variation to reveal errors. Agree the opening count, how new movements are captured, and how differences are investigated. Define who can stop the pilot if staff lose confidence in the stock record.

## Measure the process the same way before and after

Track inventory accuracy using a consistent counting method. Pair pick errors with their denominator, such as lines picked, and distinguish errors caught before dispatch from those reported by customers. Record order-release-to-dispatch time by comparable order type.

Do not interpret a quieter week as a system improvement. Compare volumes, staffing, product mix, and exceptions. The first useful outcome may be better visibility into errors rather than an immediate reduction.

Connect the warehouse plan to the [order-management guide](/services/enterprise-modernization/articles/order-management-modernization). The handoff between allocation and physical fulfillment needs to be accepted by both teams before a wider rollout.
