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.

- Customs and dual currency aren't part of your service days
- You want mature scheduling optimisation and customer comms out of the box
- You lack the capacity to own a custom field platform

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.

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.
