Revenue is up 15% but profit feels flat. Or revenue is flat and profit is down. Either way, the business is working harder for the same or less. This is margin compression — and it's one of the most common problems in growing service businesses.
Three causes most owners don't consider
First: job mix drift — you're taking on more smaller, less profitable jobs to keep crew busy. Second: customer acquisition cost creep — referrals have slowed, so you're relying more on expensive one-time leads. Third: scope creep on jobs — you're doing more for the same price because it "feels right" to keep customers happy.
The metric that catches this early
Gross margin per job tracked over time. If this number is trending down even slightly, it compounds quickly at scale. A 5% margin drop on $400K revenue is $20K per year disappearing quietly.
Marketing affects margins directly
Businesses with a strong online presence and consistent lead flow can be selective about the jobs they take. When leads are scarce, you take whatever calls. When leads are plentiful, you only take the profitable ones. That selectivity alone can recover margin without changing your pricing.
