Build a Seamless ServiceTitan Integration with Next.js: A Modern, Full-Stack Guide

Supercharge Your Service Business with a Custom ServiceTitan Integration

In the service industry—covering essential businesses like HVAC, plumbing, electrical services, and beyond—streamlined operations are key to profitability. But for companies using ServiceTitan, one of the most popular platforms for managing scheduling, dispatch, and customer communication, there's a common roadblock: the API documentation and examples are, well, limited. (Queue sad face 😢)

If you're trying to build custom solutions, you may find yourself hunting for real-world examples or best practices to get started.

That’s where Aclarify comes in.

Our latest blog post dives into a comprehensive, step-by-step guide to building a custom integration between ServiceTitan and a modern Next.js application. And this isn’t just another tutorial—it’s packed with practical insights, code examples, and solutions to common challenges that aren’t covered anywhere else.
