Your Derry supply chain runs through suppliers in the Republic, and SAP plans it as if the border isn't there
Custom supply chain software for a Derry firm costs $55k to $140k over 4 to 8 months. You build beyond SAP and generic SCM when your suppliers and customers sit on both sides of the UK/Ireland border, and planning has to account for customs clearance, dual currency and origin rules that off-the-shelf supply-chain tools treat as someone else's problem. For a North West manufacturer, the border is a planning input, not a footnote.
Generic SCM and even SAP plan a supply chain as if goods move freely. A Derry manufacturer's reality is different: materials come from suppliers in the Republic, finished goods ship to customers across the UK and beyond, and every cross-border movement carries customs clearance, commodity codes, origin rules and a currency change. The planning tool that ignores all of that gives you lead times and costs that are quietly wrong.
The expensive surprises come at the border. A shipment that the tool planned as two-day delivery sits in customs because the origin paperwork wasn't ready. A landed-cost figure that looked fine in the plan balloons once duties and the euro-to-sterling conversion are real. For medical-device and manufacturing firms in the North West whose margins depend on tight planning, a supply-chain tool blind to the border is planning fiction.
What supply chain costs in Derry
| Project scope | Typical cost | Timeline |
|---|---|---|
| Customs-aware planning core | $55k to $85k | 4 to 6 months |

| Landed-cost and customs module for existing tools | $28k to $45k | 8 to 12 weeks |
The fix: supply chain built for Derry, not rented
Custom supply chain software treats the border as a real planning input: customs clearance time, origin rules, commodity codes and the currency change are all in the model, so lead times and landed costs are honest. For a North West manufacturer whose suppliers sit in the Republic and whose margins live or die on planning accuracy, that turns the border from a source of expensive surprises into a known, planned-for variable. It connects to your ERP, inventory and warehouse systems so the plan and the reality agree.
- Your suppliers or customers span the border and customs is materially affecting lead times and cost
- Landed costs in your plan keep ballooning once duties and currency are real
- Shipments stall at the border because origin and commodity data weren't planned in
- You can't get one planning view across your dual-currency, cross-border supplier base
- Your supply chain is domestic and simple enough for generic SCM or spreadsheets
- Customs and currency aren't material to your planning
- You need the optimisation depth and templates of a mature SCM platform
- You lack the data maturity to feed a custom planning system

How long it takes, phase by phase
Exactly what you get
You get planning that respects the border. Customs clearance is in the lead times, duties and the euro-to-sterling change are in the landed cost, and origin and commodity-code data travel with every cross-border movement so nothing stalls at the border unexpectedly. You see suppliers and customers on both sides in one view, and the plan stays tied to reality through integration with your ERP, inventory management software and warehouse management system.
How to choose a developer in Derry
Ask how they'd plan a shipment of materials from a supplier in the Republic into a Derry factory and out again as finished goods, and listen for whether customs time and landed-cost duties are in their model. A developer who understands North West manufacturing treats the border as a planning input. Ask for a supply-chain or logistics system they've built that handled real cross-border movement, and how its landed-cost figures held up.
- Lead times that include realistic customs clearance, so delivery promises hold
- Landed costs that account for duties and the euro-to-sterling change before you commit
- Origin and commodity-code data built into planning so shipments don't stall at the border
- One planning view across suppliers and customers on both sides of the border
- Integration with your ERP, inventory management software and warehouse management system so plan meets reality
- Supply-chain modelling is complex and data-hungry, so this is one of the larger builds on the list
- You own keeping customs and trade rules current as cross-border arrangements evolve
- You lose the deep optimisation libraries and templates that mature SCM platforms ship
- If your supply chain is domestic and simple, generic SCM or even spreadsheets may suffice
- !They plan lead times with no customs time. Ask how clearance is built into delivery promises
- !Landed cost ignores duties and FX. Ask how the plan accounts for the euro-to-sterling change
- !No origin or commodity-code handling. Ask how shipments avoid stalling at the border
- !Single-currency supplier model. Ask how the planning view spans both sides of the border
- !No integration with ERP and inventory. Ask how the plan stays tied to real stock

Frequently asked questions
Why can't SAP or generic SCM handle our supply chain?
They plan as if goods move freely. A Derry manufacturer sourcing from the Republic and shipping across the UK has customs clearance, origin rules and a currency change on every cross-border movement. Tools blind to the border produce lead times and landed costs that are quietly wrong, with the surprises landing at customs.
How does customs-aware planning work?
The model builds realistic customs clearance time into lead times and includes duties, commodity codes and the euro-to-sterling conversion in landed cost. So a delivery promise holds and a cost figure reflects what you'll actually pay once the shipment clears the border, not an optimistic free-movement assumption.
What does supply chain software cost for a Derry manufacturer?
A customs-aware planning core runs $55k to $85k over 4 to 6 months. A full SCM with landed-cost and supplier modelling runs $95k to $140k over 6 to 8 months. A landed-cost and customs module for your existing tools is $28k to $45k.
Does it connect to our ERP and inventory?
Yes. Supply-chain planning is only as good as the stock and order data behind it, so the system integrates with your ERP, inventory management software and warehouse management system, keeping the plan tied to real stock levels and real orders.
