Your stores depot mixes export-controlled and commercial parts on the same shelf, and picking can't tell
A custom warehouse management system for a Portsmouth naval-stores or marine depot runs £50,000 to £130,000 over 4 to 7 months. Manhattan and ERP (Enterprise Resource Planning) warehouse add-ons optimise pick paths and throughput. They don't handle the constraints that govern a defence stores depot: segregating classified and export-controlled parts, enforcing cleared-handler access, and keeping certification with the lot.
Your depot holds export-controlled and classified parts on shelves next to commercial marine kit, and a generic WMS picks them all the same way, fastest path, nearest bin. But a SECRET-marked or export-controlled part can't be handled by an uncleared picker, can't be stored in the same uncontrolled zone, and can't ship without certification and the right checks. Throughput optimisation is the wrong objective when the binding constraint is who's allowed to touch the part.
Manhattan and ERP warehouse modules assume an undifferentiated stock of parcels. They don't enforce controlled zones, cleared-handler access, or certification-gated dispatch. For a naval-stores operation, the warehouse system has to know which parts are restricted, who can pick them, and that the cert travels with the lot, none of which a commercial WMS treats as core.
The problems nobody warns you about
- Classified and export-controlled parts share shelves with commercial stock, and a generic WMS can't segregate them
- Cleared-handler access to restricted parts isn't enforced by off-the-shelf warehouse tools
- Certification has to travel with the lot through picking and dispatch, which standard WMS ignores
- Pick optimisation by speed conflicts with security and control constraints that should come first
The case for owning your warehouse management
A custom WMS enforces what a naval-stores depot needs: controlled zones for classified and export-controlled parts, cleared-handler-only picking for restricted items, certification carried with the lot through to dispatch, and gated shipping for controlled components. It optimises throughput within those rules, so the warehouse runs efficiently without ever putting a restricted part in the wrong hands or the wrong zone.
Budgeting a warehouse management build in Portsmouth
| Project scope | Typical cost | Timeline |
|---|---|---|
| WMS core with zones and clearance-aware picking | £50k to £80k | 4 to 5 months |
| Plus lot certification and gated dispatch | £80k to £110k | 5 to 6 months |
| Plus ERP and scanner integration | £110k to £130k | 6 to 7 months |
What your build should include
Portsmouth warehouse management: the full scope
Digital Heroes builds the full warehouse management stack for Portsmouth teams. Typical engagements cover warehouse automation, barcode and RFID, slotting optimization, inbound and outbound logistics, fulfillment software, 3PL software and warehouse management system (WMS).
Exactly what you get
A warehouse system built for a naval-stores depot: controlled zones segregate classified and export-controlled parts, cleared-handler-only picking enforces access, certification travels with the lot through to dispatch, and shipping of controlled parts is gated. Throughput is optimised within those rules, and it integrates with your ERP, inventory, and ruggedised scanners so the controlled view runs from receipt to dispatch.
How to choose a developer in Portsmouth
Choose a developer who has built warehouse systems for regulated or controlled stock, not just fast-moving commercial fulfilment. Ask how they'd enforce controlled zones, clearance-aware picking, and certification-to-dispatch, and how they'd drive your scanning hardware. A partner who puts security and segregation ahead of raw throughput understands the job. One whose first instinct is the fastest pick path is optimising the wrong thing for a defence depot.
- !They optimise pick speed first. Ask how security and segregation come before throughput
- !No clearance-aware picking. Ask how a restricted part is kept from an uncleared handler
- !Certification ignored. Ask how the cert travels with the lot to dispatch
- !No scanner integration plan. Ask how the WMS drives your ruggedised handhelds
- !No export-control gating. Ask how a controlled part is stopped at dispatch
Teams investing in warehouse management in Portsmouth usually scope it next to business intelligence dashboards, lms, internal tools, since these systems share data and budgets.

Frequently asked questions
Why can't Manhattan or an ERP add-on do this?
Those tools optimise throughput and assume undifferentiated stock. A naval-stores depot needs controlled zones, cleared-handler picking, and certification-gated dispatch, which commercial WMS treats as data rather than enforced rules, if at all.
How does clearance-aware picking work?
The system checks the picker's clearance before assigning a restricted part, so an export-controlled or classified item can only be picked by an authorised handler. Security is enforced by the system, not left to memory.
Does it slow the warehouse down?
Enforcing zones and clearance adds a little overhead versus pure speed optimisation, but it optimises within those rules. The small efficiency cost buys you compliance and the ability to operate a controlled depot at all.
How does certification stay with a part?
Certification is held at lot level and carried through picking and dispatch, so when a part ships, its cert and traceability go with it and evidence is never lost on the warehouse floor.
