ServiceTitan schedules your engineer's day as if Derry and Donegal were one service area, and the customs delay breaks the route
Custom field service management software for a Derry firm costs $45k to $110k over 4 to 7 months. You build beyond ServiceTitan, Jobber or Housecall Pro when engineers work jobs on both sides of the border in a day, and scheduling, parts and on-site invoicing have to account for cross-border travel, dual currency and the customs friction that off-the-shelf FSM tools schedule straight through.
ServiceTitan, Jobber and Housecall Pro schedule a service day as if every job sits in one tidy service area. A Derry medical-device or equipment service firm has engineers covering Derry, Strabane and Donegal, and the tool routes them as if the border isn't there, ignoring that a parts van crossing into ROI may face customs friction and that a job in Letterkenny invoices in euro while the one before it invoiced in sterling.
The result is broken routes and wrong invoices. An engineer's day is scheduled tight, then a cross-border parts delivery is held and the whole route collapses. An on-site invoice comes out in the wrong currency because the tool assumed one. For a North West service business covering both sides of the border, an FSM tool blind to that reality schedules optimistic days that reality keeps breaking.
Where the off-the-shelf tools fall short
- Routes scheduled across the border with no allowance for customs friction on parts or travel
- On-site invoices generated in the wrong currency because the tool assumes one
- Parts and stock crossing the border with no customs handling, causing delays mid-route
- No view of which jobs are UK-side versus ROI-side for compliance and tax handling
Custom field service management: what Derry teams actually get
Custom field service software schedules the border honestly: it accounts for cross-border travel and parts friction so routes hold, raises on-site invoices in the right currency with the right VAT, and tracks which jobs are UK or ROI for compliance. For a North West service firm whose engineers genuinely work both sides in a day, that turns optimistic, frequently-broken schedules into realistic ones, and ends the wrong-currency invoices that cause disputes after the visit.

Timeline: what happens, and when
Exactly what you get
You get field service software that schedules days reality won't break. Routes account for cross-border travel and parts friction, on-site invoices come out in the right currency and VAT for UK or ROI jobs, and engineers keep working in border coverage gaps thanks to an offline app. Jobs are tracked UK-side or ROI-side for compliance. It integrates with your CRM, inventory management software and accounting software so the field and the office never disagree.
How to choose a developer in Derry
Ask how they'd schedule an engineer's day that runs from a job in Derry to one in Letterkenny with a parts pickup in between, and whether the route survives a customs delay. A developer who understands North West service work treats the border as a scheduling constraint and a currency switch. Ask for an FSM or scheduling system they've built that handled real cross-border field work, and how its routes held up.
- Realistic cross-border scheduling that accounts for customs and travel so routes actually hold
- On-site invoices raised in the correct currency and VAT for UK or ROI jobs, the first time
- Parts and stock movement across the border handled so a delivery delay doesn't collapse the route
- Clear UK-versus-ROI job tracking for compliance and tax
- Integration with your CRM, inventory management software and accounting software so the field and office agree
- Mobile, offline-capable field apps plus scheduling logic make this a substantial build
- You own keeping cross-border parts and customs handling current as rules change
- You lose the mature scheduling-optimisation and customer-comms features packaged FSM ships
- For a single-region service business, ServiceTitan or Jobber is cheaper and sufficient
- !They schedule across the border with no customs allowance. Ask how routes account for cross-border friction
- !On-site invoicing assumes one currency. Ask how a euro job invoices correctly in the field
- !No offline app. Ask what an engineer does when signal drops near the border
- !No parts customs handling. Ask how a cross-border parts delay is managed mid-route
- !No accounting integration. Ask how field invoices reconcile to the books in the right currency
Most Derry teams pricing field service management end up comparing notes on lms, crm, shopify too; the systems share one data spine. Weighing options across the region?

Frequently asked questions
Why can't ServiceTitan or Jobber handle our field team?
They schedule as if every job sits in one service area. A Derry service firm has engineers crossing the border between jobs, where customs can delay parts and travel and where a Letterkenny job invoices in euro while a Derry one invoices in sterling. Packaged FSM schedules straight through all of that, so routes break and invoices come out wrong.
How does cross-border scheduling work?
The scheduler builds realistic cross-border travel and parts friction into the route, so a day that includes a customs-affected leg isn't planned as if the van moves freely. That keeps routes achievable instead of optimistic and frequently broken.
Can engineers invoice on-site in the right currency?
Yes. The mobile app applies the correct currency and VAT based on the job's location, so a euro job in ROI and a sterling job in the UK each invoice correctly in the field, ending the wrong-currency invoices that cause disputes after the visit.
What does field service software cost?
A cross-border scheduling and invoicing core runs $45k to $70k over 4 to 5 months. A full FSM with a mobile app and parts tracking runs $80k to $110k over 6 to 7 months. A dual-currency invoicing module for an existing FSM tool is $22k to $38k.
Does it work offline near the border?
It should. Engineers regularly hit coverage gaps crossing the border, so a good build includes an offline-capable mobile app that captures job updates, parts used and signatures locally and syncs when signal returns, keeping the field and office aligned.

Who can build custom field service management software for a business in Derry?
Digital Heroes builds custom field service management 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 Derry 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 field service management 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.
