On your Derry floor, UK-bound and ROI-bound stock share the shelves, and the WMS can't tell which pallet needs customs paperwork
A custom warehouse management system for a Derry firm costs $45k to $110k over 4 to 7 months. You build beyond Manhattan or ERP (Enterprise Resource Planning) add-ons when one warehouse fulfils both UK and ROI orders, and the system has to know which stock and which shipment needs customs paperwork, origin data and a currency change. For a North West operation packing for both sides of the border off one floor, that distinction is the whole job.
Manhattan and ERP warehouse add-ons manage a warehouse as if every order ships the same way. In Derry, one floor fulfils orders to UK customers and orders to ROI customers, and the two are not the same: the ROI shipment crosses a customs border, needs origin and commodity data, and settles in euro, while the UK one doesn't. A generic WMS picks and packs both identically and leaves the customs distinction to whoever's at the dispatch desk.
That gap shows up as held shipments and dispatch-desk firefighting. A pallet goes out without the origin paperwork and gets stopped at the border; a euro order is picked but the value and tax aren't tied to the right currency for the accounts. For device and manufacturing firms in the North West fulfilling both markets from one site, the WMS that can't distinguish a cross-border order from a domestic one is a daily source of delays.
Budgeting a warehouse management build in Derry
| Project scope | Typical cost | Timeline |
|---|---|---|
| Customs-aware WMS core | $45k to $70k | 4 to 5 months |
| Full WMS with hardware and traceability | $80k to $110k | 6 to 7 months |
| Cross-border dispatch module for existing WMS | $22k to $38k | 6 to 10 weeks |
The case for owning your warehouse management
A custom WMS knows the difference between a UK and an ROI order from the moment it's picked: it flags which shipments need customs paperwork, attaches origin and commodity data, and ties euro orders to the right currency for stock value and accounts. For a North West firm fulfilling both markets off one floor, that moves the customs decision out of a person's head at the dispatch desk and into the system, so cross-border shipments leave correct and on time.
- One warehouse fulfils both UK and ROI orders and the WMS can't distinguish them
- Cross-border shipments get held at the border for missing origin or commodity paperwork
- Euro-settled orders aren't tied to the right currency for stock value and accounts
- Dispatch staff are manually deciding customs handling and making errors
- Your warehouse serves a single market and a packaged WMS or ERP add-on fits
- Customs and dual currency aren't part of your fulfilment
- You need mature slotting and optimisation more than cross-border logic
- You lack the appetite to integrate and maintain warehouse hardware

Delivery, week by week
Exactly what you get
You get a warehouse system that knows which order is which. From picking, it distinguishes UK from ROI orders, attaches origin and commodity paperwork to cross-border shipments automatically, and ties euro orders to the right currency for stock value and accounts. The customs decision lives in the system, not in a dispatcher's head, so cross-border pallets leave correct and on time. It integrates with your ERP, inventory management software and supply chain software so the floor and the plan agree.
How to choose a developer in Derry
Ask how they'd handle a pick list where some orders ship to Belfast and others to Buncrana, and listen for whether the system flags the customs difference itself. A developer who understands North West fulfilment treats the UK/ROI distinction as core. Press on scanner and label-printer integration, and ask for a WMS or fulfilment system they've shipped that handled real cross-border dispatch.
- Picking and packing that distinguishes UK from ROI orders so cross-border shipments are handled right
- Origin and commodity paperwork attached automatically so cross-border pallets don't get held
- Euro orders tied to the right currency for accurate stock value and clean accounting
- The customs decision moved from the dispatch desk into the system, cutting held-shipment errors
- Integration with your ERP, inventory management software and supply chain software so the floor and the plan agree
- WMS builds touch real hardware (scanners, label printers) which adds integration cost and time
- You own keeping customs and trade-document requirements current as rules change
- You lose the mature optimisation and slotting algorithms platforms like Manhattan ship
- For a single-market warehouse, an ERP add-on or packaged WMS is cheaper and sufficient
- !The WMS treats all orders the same. Ask how it flags a cross-border order at picking
- !No customs-document generation. Ask how origin and commodity data is attached automatically
- !No dual-currency handling. Ask how a euro order ties to the right stock value and tax
- !Vague on hardware. Ask how scanners and label printers integrate for cross-border dispatch
- !No ERP integration. Ask how the floor stays aligned with stock and the supply-chain plan

Frequently asked questions
Why can't Manhattan or an ERP add-on handle our warehouse?
They manage fulfilment as if every order ships the same way. A Derry warehouse fulfilling both UK and ROI orders from one floor needs the system to know which shipments cross the border, need origin and commodity paperwork, and settle in euro. Generic WMS leaves that distinction to the dispatch desk, where errors and held shipments happen.
How does a customs-aware WMS prevent held shipments?
It classifies orders at picking, flags which ones cross the border, and generates the origin and commodity-code paperwork automatically so the pallet leaves with the right documents. The customs decision is in the system rather than relying on a dispatcher to remember it for every order.
Does it handle dual-currency orders?
Yes. Euro-settled orders are tied to the right currency for stock value and tax, so fulfilment data flows correctly into your accounting and inventory systems rather than being reconciled by hand after dispatch.
What does a custom WMS cost?
A customs-aware WMS core runs $45k to $70k over 4 to 5 months. A full system with hardware integration and traceability runs $80k to $110k over 6 to 7 months. A cross-border dispatch module for an existing WMS is $22k to $38k.
Will it work with our existing warehouse hardware?
A good build integrates with your scanners and label printers and is designed around real dispatch workflows. Hardware integration adds cost and time, which is why it's worth scoping carefully, but it's essential for a WMS that handles cross-border dispatch reliably.
