Your London importer's supply chain now runs through a customs broker that SAP never planned for
Custom supply chain software in London typically costs £70k to £200k over 5 to 9 months. You build custom when your supply chain crosses borders and customs in ways generic SCM can't model, when post-Brexit broker handoffs, duty calculations, and lead-time variability sit outside SAP in spreadsheets and emails. For a London importer or distributor, the trigger is when a customs delay you couldn't see coming empties a shelf.
SAP and generic SCM tools model a clean supply chain: supplier, shipment, warehouse, done. Your London import operation post-Brexit doesn't look like that. Goods move through a customs broker, clear under specific commodity codes, attract duty that varies by origin and trade agreement, and face lead times that swing with port congestion and border checks. The off-the-shelf system has no real home for the customs layer, so it lives in broker emails, spreadsheets, and your team's heads.
That blind spot costs you. A shipment held at customs is invisible to the system until it's already late, and by then you're firefighting a stockout. Duty miscalculations surface as nasty surprises. Lead-time variability isn't modelled, so your planning assumes a certainty that the post-Brexit border doesn't offer. The supply chain tool gives you visibility right up to the point where, in London, the real risk now lives.
Why the usual tools struggle in London
- Customs broker handoffs and clearance status live in emails, invisible to SAP
- Duty varies by origin and trade agreement and gets calculated outside the system
- Post-Brexit lead-time variability isn't modelled, so planning assumes false certainty
- A shipment held at customs becomes visible only once it's already late
What a custom supply chain build changes
A London importer's supply chain has a customs and broker layer post-Brexit that generic SCM was never designed to model. Custom supply chain software brings that layer into the system: broker handoffs and clearance status tracked live, duty calculated by origin and trade agreement, and lead times modelled with the real variability the border introduces. You see a customs hold while you can still react, not after the shelf is empty. The blind spot where your actual risk now lives finally has instrumentation.

From kickoff to launch: the schedule
Exactly what you get
Supply chain software that sees through to where your risk now lives: the post-Brexit customs layer. Broker handoffs and clearance status tracked live, duty calculated by commodity code and trade agreement, and lead times modelled with the variability the border actually introduces. A customs hold raises an alert while you can still re-route or expedite, not after the shelf empties. You get one picture of the chain through to clearance, replacing the broker emails and spreadsheets where that knowledge currently hides.
How to choose a developer in London
Hire a team that understands post-Brexit customs and trade logic, not just warehouse-to-warehouse SCM, because that customs layer is the whole point. Ask how they'd cost a shipment from a new origin under a specific trade agreement, and how they'd surface a customs hold early. A partner who stops modelling at the border has missed your actual problem. Connect the build to your inventory management software, warehouse management system, and ERP (Enterprise Resource Planning) so customs, stock, and finance share one view of every shipment.
- Live customs clearance and broker-handoff status inside the system, not in emails
- Duty calculated automatically by origin and trade agreement, ending surprise costs
- Lead times modelled with post-Brexit variability so planning reflects reality
- Early warning on customs holds while you can still re-route or expedite
- One picture of the supply chain through to clearance, not just to the border
- Modelling customs and trade-agreement logic is complex and drives cost
- You own the duty and tariff rules as trade agreements change
- Integration with broker systems and carriers is where most project risk sits
- If your supply chain is domestic or simple, generic SCM is the right, cheaper tool
- !They model the chain only to the warehouse; ask how they handle customs clearance
- !No duty or trade-agreement logic; ask how they cost a shipment from a new origin
- !Broker integration is hand-waved; ask which broker systems they've connected
- !Lead times are treated as fixed; ask how they model border variability
- !Quote without mapping your import flow; ask for a supply-chain audit first

Frequently asked questions
Why doesn't SAP handle our customs problem?
SAP and generic SCM model the chain from supplier to warehouse but treat customs as a black box. Post-Brexit, the customs layer, broker handoffs, duty, clearance delays, is where London importers carry the most risk, and it ends up in emails and spreadsheets. Custom software brings it into the system.
How does the software give early warning on customs holds?
By integrating with broker and carrier systems to track clearance status live, so a held shipment raises an alert while you can still react, re-routing, expediting, or adjusting orders, rather than discovering it once the goods are already late.
Can it calculate duty automatically?
Yes. The system calculates duty by commodity code, origin, and applicable trade agreement, replacing the manual, error-prone calculations that currently produce surprise costs at clearance. As trade agreements change, the rules are updated centrally.
Do we need to replace our existing SCM?
Often not. A custom customs and lead-time layer can sit over your existing SCM, adding the post-Brexit visibility it lacks while keeping the rest of your supply chain tooling. Full replacement only makes sense if the base system is itself the constraint.
How long does a supply chain build take?
Five to nine months. A customs and lead-time layer over existing SCM lands in five to seven; a full platform with customs modelling runs seven to nine. The customs, duty, and broker-integration logic drives most of the timeline.
How much does a custom warehouse management system cost to build?
Why do agencies charge for a discovery phase instead of quoting for free?

Who can build custom supply chain software for a business in London?
Digital Heroes builds custom supply chain software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in London gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other supply chain software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
