The Quick Answer
Service Fusion suits HVAC operations with 5–25 technicians that want transparent pricing, unlimited users, and solid core functionality (scheduling, dispatch, invoicing, QuickBooks) without the complexity and cost of enterprise software.
ServiceTitan targets established HVAC companies with 15+ technicians where maintenance agreement automation, flat-rate pricing management, and advanced revenue reporting justify the cost premium.
If your team is under 15 technicians and you're not running a high-volume maintenance agreement model, Service Fusion is the more proportionate choice.
Pricing Comparison
Service Fusion — Published Pricing
| Plan | Users | Annual Cost | Key Features |
|---|---|---|---|
| Starter | Unlimited | $208/month | Core FSM + QuickBooks |
| Plus | Unlimited | $325/month | + Photos, inventory, job costing, voice/text |
| Pro | Unlimited | $533/month | + Open API |
Important billing detail: Annual billing requires full-year upfront payment. Plus tier is approximately $3,900 at sign-up — not monthly instalments.
ServiceTitan — Quote Required
No published pricing. Three tiers (Starter, Essentials, The Works) all require a custom demo and quote. Reviewers consistently describe ServiceTitan as among the most expensive platforms in the HVAC market.

Service Fusion's Strongest Case
Unlimited users at flat pricing. Service Fusion's per-plan (not per-seat) model means a growing team doesn't generate growing subscription costs. A crew that expands from 8 to 12 technicians pays the same monthly fee — a meaningful financial planning advantage.
QuickBooks at Starter. Including QuickBooks integration in the baseline plan is unusual at the mid-market level. Most competitors lock it to mid-tier pricing.
Transparent pricing. You can evaluate cost before a demo. You can build a budget without a sales conversation.
Service Fusion's Honest Weaknesses
No flat-rate pricebook. Flat-rate pricing — presenting customers with a fixed price before starting work — is standard practice in residential HVAC. Service Fusion doesn't include it, which is a meaningful gap for residential-focused operations.
Upfront annual billing. $3,900 upfront for Plus tier is a significant commitment without a free trial to validate fit first.
Mobile app consistency. User reviews flag occasional reliability issues with the mobile app — a practical problem when technicians are in the field.
ServiceTitan's Strongest Case
The most feature-complete platform for mid-to-large HVAC. For operations with 15+ technicians, maintenance agreement volume, and a focus on revenue-per-customer optimisation, ServiceTitan has no direct competitor. The flat-rate pricebook, maintenance renewal automation, call booking workflow, and marketing attribution tools are genuinely differentiated.
Revenue generation focus. ServiceTitan positions software as a revenue tool, not just an operations tool. Businesses that use it at scale tend to retain it because the incremental revenue from better-managed service calls justifies the cost.
ServiceTitan's Honest Weaknesses
Cost and implementation. Among the most expensive platforms in the market. Implementation is months-long and requires significant team investment.
Overkill for most small HVAC businesses. For operations under 10 technicians, the enterprise features rarely generate enough incremental revenue to justify the premium.
