Speaking the language of this industry
- Dispatch — assigning and routing a technician or crew to a scheduled job based on skill, location, certification, and availability
- Change order — a documented adjustment to a job's scope, price, or materials discovered after the original estimate was approved
- Truck roll — any trip a technician makes to a job site, the cost driver every contractor tries to minimize per completed job
- First-visit completion — a job resolved fully on the initial visit, with no return trip or callback required
- Callback — a return visit for the same problem on the same job, distinct from a new sale or a maintenance-agreement visit
- Maintenance agreement — a recurring service contract (seasonal HVAC tune-ups, quarterly pest treatments) with its own schedule and renewal date
- Job costing — matching actual labor, material, and change-order cost against the priced estimate to determine real margin on a specific job
- Crew lead — the technician responsible for a multi-person crew on a job, the point of contact between the field and dispatch
- Punch list — the remaining items to complete or correct before a customer or general contractor signs off on finished work
- Draw / progress billing — invoicing tied to project milestones rather than a single final invoice, common on general-contracting jobs
- Toolbox talk — a documented pre-job safety briefing, required for OSHA compliance on many crews and often audited after an incident
