Your Plymouth inventory system picks an ITAR-flagged component for an overseas order, because it doesn't know the difference
Custom inventory management software for a Plymouth marine or defence firm typically costs £35,000 to £90,000 over 3 to 6 months. Fishbowl and Cin7 track quantities and locations well; they have no concept of export control, batch traceability to a naval standard, or clearance-gated stock, which is exactly what marine-engineering and defence inventory demands.
Standard inventory tools answer how many and where. Defence and marine inventory has to answer harder questions: is this part export-controlled, what batch and certificate does it carry, which vessel and contract is it earmarked for, and is the person picking it cleared to handle it. Fishbowl and Cin7 don't ask any of those, so a controlled component can be picked for an overseas order with nothing in the system to stop it.
Traceability is the other gap. When a naval prime asks which batch of a fitting went onto which vessel, you need certificate-level history, not a stock count. Spreadsheets pretending to do this are how a recall or audit turns into a week of frantic reconstruction.
The fix: inventory management built for Plymouth, not rented
Custom inventory software makes export status, batch traceability, and clearance into core attributes of stock. A controlled part can't be allocated to an ineligible order, every item carries certificate-level history to its vessel and contract, and an audit or recall query is answered from records you already hold. It keeps the warehouse fundamentals and adds the traceability and control that marine and defence work require.

How long it takes, phase by phase
Exactly what you get
You get inventory software that knows the difference between a commodity bolt and an export-controlled naval component: controlled parts blocked from ineligible orders, certificate-level traceability from goods-in to the vessel it went onto, stock reserved against real contracts, and sensitive items picked only by eligible staff. It integrates with your ERP, warehouse management system, and supply chain tools so the whole chain stays honest.
How to choose a developer in Plymouth
Pick a team that understands defence and marine traceability, not just stock counts. Ask how the system blocks a controlled allocation and how it answers a batch recall. Confirm it integrates with your ERP and warehouse management software so stock isn't tracked twice, and beware anyone who treats export control as a cosmetic flag rather than an enforced rule.
- Export-controlled parts flagged and blocked from ineligible allocations automatically
- Batch- and certificate-level traceability from receipt to vessel and contract
- Stock reservations tied to specific vessels, jobs, and primes
- Clearance-aware handling so only eligible staff pick sensitive components
- Clean integration with your ERP, warehouse management, and supply chain tools
- Higher upfront cost than a Fishbowl or Cin7 subscription
- Detailed traceability adds discipline your warehouse team must adopt
- Export and clearance rules embedded in stock logic need maintaining
- For simple, non-controlled commercial stock, off-the-shelf tools are cheaper and fine
- !A vendor who treats export status as a label; ask how it blocks an ineligible allocation
- !No batch traceability story; ask how they'd answer a naval recall query
- !Ignoring clearance at picking; ask how sensitive parts are protected
- !No ERP or WMS integration plan; ask how stock stays consistent across systems
- !Generic warehouse demo; ask to see traceability and control specifically

Frequently asked questions
Why can't Fishbowl or Cin7 handle our defence inventory?
They track quantity and location but have no native concept of export control, certificate-level batch traceability, or clearance-gated picking. For Plymouth marine and defence stock, those are exactly the controls a naval prime and an audit check, so they end up being custom.
How does the system stop a controlled part shipping overseas?
Export-controlled items carry a classification that the software checks at allocation. If an order's destination or customer isn't eligible, the system blocks the allocation rather than letting a controlled component quietly get picked.
What does certificate-level traceability mean in practice?
Every item carries its batch, lot, and certificate from goods-in through to the vessel and contract it's dispatched against. When a naval prime asks which batch went onto which vessel, you answer from records instead of reconstructing it by hand.
Will it integrate with our ERP and warehouse system?
It should. Custom inventory software is most valuable when it shares one truth with your ERP and warehouse management system, so stock isn't counted twice or allowed to drift between tools.
Is this necessary for non-controlled stock?
No. For ordinary commercial goods with no export or clearance angle, Fishbowl or Cin7 is cheaper and perfectly capable. The custom case is control, traceability, and clearance, which define defence and marine inventory.
