How One Business Buyer Finally Saw Profitability by Service Line — on Day One Acquisition entrepreneurs inherit chaos. They get spreadsheets, point-of-sale systems, job records scattered across emails. What they don't get: profitability by service line—clarity on which work actually makes money. This home services buyer was no exception. Day one after closing, he had no idea which service category was profitable. Install jobs? Service calls? Maintenance plans? The data existed—it was just trapped in ServiceTitan, disconnected from accounting, invisible to strategy. The Problem: Data Without Insight Home services businesses run on operational efficiency. Job times, crew costs, customer retention—all critical. But the financial picture? Usually invisible until tax time. When you acquire a business, you inherit its blind spots.

"That insight alone was worth the engagement," Chris says. "Once the buyer saw it in the data, the conversation shifted from 'What should we do?' to 'How do we double down on what's actually working?'" The Decision: First-Year Strategy, Built on Data Armed with this insight, the buyer's sales strategy shifted immediately. Not away from service calls—those maintain relationships. But the growth dollars went to what was already working. Lean into installs. Hire for install capacity. Market install services more aggressively. Build the service call base as a foundation, not the...
