Your Coventry stores feed the M6 freight corridor and your WMS is an ERP afterthought
A warehouse feeding a JIT automotive line or a fast logistics operation off the M6 needs real directed picking, sequencing, and traceability, which is exactly what Manhattan-scale suites overshoot and ERP (Enterprise Resource Planning) add-on modules undershoot. A custom warehouse management system costs £50,000 to £130,000 over 4 to 7 months and pays back by getting the right parts to the line in the right sequence without a forklift driver guessing.
ERP warehouse add-ons treat the warehouse as a stock location, not a process. A Coventry stores feeding a JIT line has to pick parts in build sequence, manage line-side replenishment by Kanban, and trace every batch to the dispatch, and the bolt-on module handles none of it, so the warehouse runs on the supervisor's knowledge and a clipboard. At the other extreme, a Manhattan-class WMS is built for a national distribution centre and is overkill and over-budget for a plant stores.
The cost of the gap is in the picking. Without directed, sequenced picking, a forklift driver walks the wrong route, picks the wrong revision of a part, or replenishes line-side too late, and any of those stops a JIT line or feeds a defect downstream. The warehouse is where traceability and timing both live, and an ERP afterthought is the wrong tool for both.
Where the off-the-shelf tools fall short
- ERP warehouse add-ons treat the stores as a location, not a sequenced process
- JIT line-side replenishment runs on a supervisor's head and a clipboard
- Pickers can grab the wrong part revision with no directed, sequenced picking
- Batch traceability to dispatch isn't held where the picking actually happens
Custom warehouse management: what Coventry teams actually get
A custom WMS, sized for a plant stores rather than a national DC, gives you directed and sequenced picking, Kanban line-side replenishment, and batch traceability through to dispatch, all on devices the warehouse team actually uses. The driver is told the route, the part, and the revision, and the line gets the right parts in the right order without depending on one supervisor's memory.
- Your stores feed a JIT line that needs sequenced picking
- Line-side replenishment runs on one person's knowledge
- Wrong-revision picks are feeding defects downstream
- Batch traceability must live at the point of pick
- Your warehouse is small, slow, and non-sequenced
- An ERP add-on genuinely handles your picking
- You have no JIT replenishment obligations
- Volumes don't justify directed picking
- Directed, sequenced picking so parts reach the line in build order
- Kanban line-side replenishment that doesn't depend on a supervisor's memory
- Revision-correct picking that stops the wrong part feeding a defect
- Batch traceability captured where picking happens, ready for audit
- Right-sized for a plant stores, not the cost of a national-DC suite
- Needs reliable scanning hardware and warehouse Wi-Fi to work
- More than an ERP add-on module, though far less than Manhattan-class suites
- Tight integration with ERP and inventory adds dependencies
- Overkill for a small, simple, non-JIT store

Timeline: what happens, and when
Exactly what you get
A warehouse management system sized for a plant stores: directed and sequenced picking so parts reach the line in build order, Kanban line-side replenishment that doesn't rely on one supervisor, revision and batch verification at the point of pick, and traceability through to the dispatch note. It runs on the handhelds and forklift terminals the warehouse team actually uses. It integrates tightly with your inventory management system for stock, your ERP for orders, and your supply chain software for inbound scheduling.
How to choose a developer in Coventry
Ask how they'd sequence picking to a build order and trigger line-side replenishment without a supervisor babysitting it, and watch whether they reach for a real warehouse process or a stock-location screen. The right developer sizes the system to a plant stores, not a national DC. A team that knows Coventry's JIT automotive stores and the M6 logistics corridor will treat sequenced picking and line-side timing as the heart of the build, with traceability captured where the picking happens.
- !No sequenced-picking experience; ask how they pick parts in build order
- !They quote a Manhattan-class suite; ask why a plant stores needs that scale
- !No revision verification; ask how a wrong-revision pick gets blocked
- !No traceability at pick; ask how batch data reaches the dispatch note
- !No hardware plan; ask what scanners and terminals the warehouse will use

Frequently asked questions
Why aren't ERP warehouse add-ons enough?
Because they treat the warehouse as a stock location rather than a sequenced process, so JIT line-side replenishment and directed picking run on a supervisor's knowledge and a clipboard. A custom WMS gives the driver the route, the part, and the revision, which is what keeps a JIT line fed.
Isn't a system like Manhattan the safe choice?
Only if you run a national distribution centre. For a Coventry plant stores, a Manhattan-class suite is overkill and over-budget. A right-sized custom WMS gives you sequenced picking and traceability without paying for enterprise-DC scale you'll never use.
How does it prevent wrong-revision picks?
By verifying part revision and batch at the point of pick, so the system blocks a driver from grabbing the wrong revision before it ever reaches the line. Wrong-revision picks are a common source of downstream defects that directed picking eliminates.
What does a custom WMS cost?
A directed-picking and replenishment WMS runs £50,000 to £80,000. Adding sequencing and batch traceability takes it to £105,000, and a full WMS with slotting and ERP integration reaches £130,000, over 4 to 7 months.
What hardware do we need?
Reliable warehouse Wi-Fi and scanning devices, typically handhelds for pickers and mounted terminals on forklifts. The software is only as good as the scanning discipline and coverage, so we scope hardware against your warehouse layout in discovery.
