Build a consistent numerical view of dispatch, job capacity, and service delivery before changing a field-service workflow.
Field service calculators
HVAC Sub-10-Truck Dispatch Optimization Modeler
Compare job capacity and contribution for an HVAC fleet of 1–9 trucks under current and proposed travel-time assumptions.
Start with the operating constraint
Identify the limiting resource: available trucks, qualified technicians, travel time, job duration, or service windows. Measure capacity in the same unit and period as incoming work. Keep booked time separate from productive service time.
Compare a baseline and a proposed workflow
For each case, record completed jobs, travel hours, paid hours, repeat visits, and contribution per completed job. Include overtime, dispatch administration, and implementation costs. Assess whether a change improves both delivery reliability and the economics of service.
Use the same reconciliation discipline
Completed jobs should connect to approved billable work and matching invoices. The CRM-to-billing calculator can quantify an unexplained billing difference after known exclusions.
