FIELD SERVICE
Choosing a custom field service app or ServiceTitan comes down to fit and cost over time. A platform like ServiceTitan gets you running fast on common workflows, while a custom app wins when your operation does not fit the platform or its per seat pricing stops making sense.
What a platform like ServiceTitan does well
Established platforms cover scheduling, dispatch, work orders, invoicing, and reporting out of the box, and they are maintained for you. For a common HVAC or plumbing operation, that is a fast start with little up front cost.
Most operations should begin there. The US field service software market is about 3.1 billion dollars in 2026 and growing steadily, and platforms are where the majority of that activity sits.
Where a custom field service app wins
Custom wins when your workflow is unusual, when per seat fees scale painfully as you add technicians, when you need integrations the platform does not offer, or when the app is part of how you compete. You own it, it fits exactly, and the cost does not rise just because you hired.
The features that earn their keep in the field are worth knowing before you build, covered in the dispatch and work order features techs actually use.
The real cost on each side
A platform gives you a fast start and low up front cost, but recurring per seat fees, limited control, and the risk of outgrowing it. A custom app costs more up front and then becomes an asset you own with no per seat tax. The crossover is usually a function of team size and how well your workflow fits the platform.
If the platform already feels tight, the question may be less which to pick and more what to do once you have outgrown the platform.
How Tepia approaches the choice
Tepia helps operations decide honestly, then builds custom only when the platform genuinely does not fit. Thirteen years of engineering goes into making the crossover math clear before anyone commits to a build.
