Your Derby stores team picks serialised flight parts with a clipboard while the ERP add-on guesses location
A custom warehouse management system for a Derby engineering business handles serialised and traceable parts, free-issue stock segregation, and directed picking that ERP (Enterprise Resource Planning) add-ons and Manhattan-style generics handle poorly. Expect $55k to $130k and 4 to 8 months. The win is knowing the exact serialised location of every part, picking the right serial against a works order, and keeping customer-owned stock segregated, instead of a bin-location guess and a clipboard that loses traceability in the stores.
You hold and move serialised engineering parts in Derby, and your stores are where traceability quietly breaks. ERP warehouse add-ons and generic WMS tools assume interchangeable units in bins, but your parts are individually serialised, some are customer-owned free-issue stock, and picking the wrong serial against a works order is not a minor error, it is a traceability failure that can scrap a build or trigger a concession.
So the stores team works from clipboards and memory, location data drifts because the ERP add-on was never designed for serialised reality, and the moment an auditor asks you to prove segregation of free-issue stock or pick history of a specific serial, the answer is reconstructed rather than recorded. A warehouse that handles flight and rail parts needs more than a bin count; it needs to know which serial is where and prove it.
- Your parts are serialised and the ERP add-on only tracks bins of units
- You hold free-issue stock that must be segregated and proven for audit
- Picking the wrong serial against a works order is a real traceability risk
- Location data drifts because stores run on clipboards and memory
- Your stock is non-serialised commodity items in standard bins
- An ERP warehouse add-on genuinely covers your putaway and picking
- You hold no customer-owned stock to segregate
- Volumes are low and a generic WMS meets your needs
- Exact serialised location of every part, so picking the right serial is directed, not guessed
- Free-issue and customer-owned stock segregated and provable for audit
- Pick and move history recorded per serial, so traceability survives the stores
- Directed picking against the works order that prevents wrong-serial errors
- Built for Derby serialised aerospace and rail stock, not a generic bin-count warehouse
- Serialised WMS adds scanning discipline the clipboard process did not require
- It needs barcode or RFID hardware and integration, which is cost beyond the software
- A custom build costs more than an ERP warehouse add-on
- For non-serialised commodity stock, a generic WMS or ERP add-on is cheaper and adequate
The honest cost picture for Derby
| Project scope | Typical cost | Timeline |
|---|---|---|
| Serialised WMS with directed picking | $55k to $90k | 4 to 6 months |
| Full WMS with free-issue segregation and ERP sync | $90k to $130k | 7 to 8 months |
| Annual support and enhancements | $14k to $30k | ongoing |
Feature priorities for Derby teams
Derby warehouse management: the full scope
The engagements Derby teams bring us most often: inbound and outbound logistics, fulfillment software, 3PL software, warehouse management system (WMS), WMS development, pick pack ship and warehouse automation.
Exactly what you get
You get directed putaway and picking that select the correct serial against the works order, free-issue stock segregated and provable, and a full move history per serial so the stores stop being where traceability breaks. Scanning binds every move to a serial and a location, so the count never drifts. It works with your ERP, inventory management system and traceability spine, and feeds picking accuracy and stock turn into business intelligence dashboards.
How to choose a developer in Derby
Choose a team that understands a serialised flight part is not an interchangeable unit and designs directed picking and free-issue segregation accordingly. Insist on serial-level move history, works-order-driven picking and a hardware plan for scanning. Avoid anyone who offers a bin-count warehouse add-on or has no answer for customer-owned stock and serial-level audit history.
Timeline: what happens, and when
- !They track bins of units; ask how directed picking selects the right serial
- !No free-issue handling; ask how customer-owned stock is segregated and proven
- !No move history per serial; ask how pick history is produced for an auditor
- !No hardware plan; ask how scanning binds a move to a serial and location
- !They quote before seeing your stores; ask them to watch a serialised pick first
If warehouse management is on the roadmap, business intelligence dashboards, lms, internal tools usually follow within the year. Budget them as one conversation.

Frequently asked questions
Why is an ERP warehouse add-on not enough?
ERP add-ons and generic WMS tools assume interchangeable units in bins. Your engineering parts are individually serialised, some are customer-owned, and picking the wrong serial against a works order is a traceability failure. The add-on was never designed for serialised, segregated, auditable stock, so the stores fall back to clipboards.
How does directed picking prevent wrong-serial errors?
The system tells the picker the exact serial and location to take for a works order and verifies it by scan, so the correct serial is picked by design rather than judgement. That removes the wrong-serial errors that turn into concessions and scrapped builds.
Can it segregate free-issue stock?
Yes. Customer-owned free-issue and consignment stock is stored and accounted for separately, with its own audit history, so you can prove segregation on demand rather than reconstructing it. This is a common reason Derby suppliers move beyond an ERP add-on.
Do we need barcode or RFID hardware?
Yes, scanning is what binds every move to a serial and a location so the count cannot drift. The hardware is a cost beyond the software, but it is what makes serialised traceability in the stores real rather than a clipboard estimate.
What does it cost to maintain?
Budget $14k to $30k a year for support, hardware upkeep and enhancements. The ongoing requirement is the scanning discipline, since the location and pick accuracy depend on the stores team scanning every move rather than working from memory.
