How do I track service calls vs installation jobs?
Service calls and installation jobs have completely different profit profiles, and lumping them together hides important information about your business. Service work is typically high-margin but time-sensitive. Installations are materials-heavy with tighter margins but larger dollar amounts. Without separating them, you can’t tell which side of your business is actually making money.
The simplest approach in QuickBooks is using classes. Create a class for “Service” and a class for “Installation.” Every transaction gets tagged with the appropriate class, which lets you run profit and loss reports filtered by class to see each segment separately. A contractor bookkeeper in American Fork can set this up so the structure makes sense for how your business actually operates.
Some contractors prefer using different job prefixes instead. Service calls might be “SVC-” followed by customer name and date. Installations get “INST-” with the project name. The naming convention doesn’t matter as long as it’s consistent and everyone on your team follows it.
Service calls need different cost tracking than installations. With service work, your main cost is technician time. Track travel time, diagnostic time, and repair time separately if you want to understand efficiency. Materials on service calls are usually minimal or come from truck stock that gets replenished periodically.
Installation jobs need full job costing. Track materials purchased specifically for that job. Track labor hours by phase if the project spans multiple days. Include subcontractor costs if you’re bringing in help. The goal is knowing your actual cost on each installation so you can compare it to your bid.
Overhead allocation gets tricky. Your truck costs, insurance, and shop rent support both service and installation work. Most contractors don’t need perfect allocation. A reasonable estimate works fine. The real insight comes from tracking direct costs accurately, not from perfecting overhead distribution.
The reporting payoff is significant. You can see average revenue per service call, average profit margin on installations, which technicians are most profitable on service work, and whether your installation bids are accurate. These numbers help you make decisions about pricing, hiring, and which types of work to pursue.
One common mistake is tracking every service call as its own job. This creates hundreds of tiny jobs that clutter your system and make reporting unwieldy. Consider grouping service calls by customer or by week for job tracking purposes while still tagging each transaction with the Service class for segment analysis.
Another mistake is inconsistent coding. If half your team forgets to tag transactions or uses the wrong classification, your reports become unreliable. Build the coding into your workflow so it happens automatically. The numbers only help you if the data going in is accurate.
