FSM-Sim Whitepaper: Field Service Workflow Comparison Using FSM-Sim™ 2.5
Executive Summary
Ucora's 2026 whitepaper uses FSM-Sim™ 2.5 to compare two commercial HVAC field service workflows over 261 days with identical demand, cost assumptions, and service parameters. Company A follows a traditional estimator-based process. Company B removes the estimator bottleneck and lets technicians quote directly in the field using automated pricing.
The streamlined workflow delivered materially stronger acceptance, throughput, and profitability, while also surfacing the operational realities that come with scale, especially in dispatching and accounting.
84%
Acceptance rate in the streamlined workflow, compared with 57% in the traditional workflow.
6,405
Jobs completed in the streamlined workflow, compared with 1,171 in the traditional workflow.
$2.90 M
Gross profit in the streamlined workflow, compared with $0.25 M in the traditional workflow.

What the whitepaper covers
The paper looks at one of the most practical commercial HVAC workflow questions: what changes when quoting moves from an office estimator to the technician in the field?
Company A: Traditional workflow
- Dispatcher receives the request and sends a technician to site.
- The technician assesses the work.
- An estimator in the office prepares and reviews the quote.
- The customer sees the quote after the site visit and office handoff.
Company B: Streamlined workflow
- Dispatcher receives the request and sends a technician to site.
- The technician quotes directly in the field using automated pricing.
- The customer receives the quote while the technician is still engaged.
The estimator role is removed, which speeds up delivery but shifts more responsibility into the field workflow.
How the simulation was set up
FSM-Sim™ 2.5 held the two companies to the same baseline conditions so the workflow comparison stayed clean.
- The process ran for 261 days, the equivalent of one operating year.
- Both companies shared identical demand, cost assumptions, and service parameters.
- Each company started with four technicians, one dispatcher, and one accountant.
- The meaningful differences were workflow structure, and the presence or absence of estimators.
Key findings
23 h 24 min
Average quote turnaround in the streamlined workflow, down from 1 day 6 h in the traditional workflow.
$8.85 M
Revenue collected in the streamlined workflow, compared with $1.61 M in the traditional workflow.
~33%
Profit margin in the streamlined workflow, compared with roughly 15% in the traditional workflow.
The paper also shows the tradeoffs. The streamlined company scaled from four technicians to twenty-two, grew dispatch from one person to three, and expanded accounting from one person to four.
What commercial HVAC leaders should take from it
First, faster quoting is not just a speed improvement. It is a demand-capture improvement. When the customer gets a clear price while the technician is still on site, acceptance rises sharply and far more requests convert into completed work.
Second, removing estimator delays does not remove operational complexity. It shifts that complexity into technician enablement, pricing logic, dispatch coordination, and billing discipline. That is why workflow design matters more than just adding features to a generic FSM stack.
- Direct in-field quoting can unlock materially higher win rates and throughput.
- Commercial HVAC companies still need strong dispatch and accounting processes as volume increases.
- Price consistency depends on training, intuitive tools, and workflow guardrails.
- The right system should support commercial HVAC execution, not just store data after the fact.
