5 KPIs Every Service Business Should Track

Revenue and profit are important — but they’re lagging indicators. By the time they show a problem, you’re already behind. The best service businesses track leading indicators: metrics that predict future performance before it shows up in the financials.

Here are five KPIs that should be on every service business dashboard, regardless of whether you’re in HVAC, landscaping, consulting, or home care.

1. Customer Acquisition Cost (CAC)

How much does it cost you to acquire one new customer? Include all marketing spend, sales time, and any referral fees. If your average job is worth $800 and it costs you $400 to get that customer, your economics are very different than if your CAC is $80.

2. Job Completion Rate

What percentage of booked jobs actually complete as scheduled? Cancellations and no-shows kill capacity planning and revenue predictability. A rate below 85% is a red flag — either your scheduling process, your customer communication, or your service quality needs attention.

3. Average Revenue Per Customer

Are you growing revenue by adding new customers, or are existing customers spending more? Tracking revenue per customer over time tells you whether your upsell and retention efforts are working.

4. Net Promoter Score (NPS)

Ask every customer one question after job completion: “How likely are you to recommend us to a friend?” Score it 0–10. Anyone who answers 9 or 10 is a promoter. Subtract detractors (0–6) from promoters to get your NPS. Anything above 50 is excellent for service businesses.

5. Technician Utilization Rate

What percentage of your technicians’ available hours are billable? Industry benchmark is 75–80%. Below that, you have scheduling or sales problems. Above 90%, you’re at risk of burnout and quality issues.
