EternalEngine vs Service Fusion
Service Fusion is a field-service management platform for HVAC, plumbing, electrical and similar trades, priced per account with unlimited users included on every tier.
The price story
Service Fusion: From $245/mo (Starter, month-to-month; $208/mo billed annually) — unlimited users included. EternalEngine: from $9.95/mo (Basic), Team at $49/mo for 3 users, every paid plan with a 30-day free trial —full plan ladder.
Service Fusion's unlimited-user model means a 3-person shop pays the same $245/mo (month-to-month; $208/mo annual) as a 20-person shop on the Starter tier — no per-seat savings at small team sizes. EternalEngine Team is $49/mo for 3 users, about a fifth of the price, though Service Fusion's unlimited-seat structure can look more attractive once a team genuinely outgrows per-seat pricing.

EternalEngine vs Service Fusion questions
Is Service Fusion cheaper once my crew is bigger?
It can be — unlimited users means a 15-person crew on Starter still pays $245/mo (or $208/mo annual), while EternalEngine would need Business ($199/mo, 15 seats included) at that size. Do the math against your actual headcount rather than assuming either is automatically cheaper.
What do I get for $245/mo with Service Fusion that I would not get for $9.95–$49/mo with EternalEngine?
Field dispatch and GPS tracking are included from their entry tier; on EternalEngine those (CrewGrid) start on Pro at $99/mo for 5 users. If dispatch is your day-one requirement and you are already a multi-tech shop, the comparison narrows.
Can I import my Service Fusion data?
Yes. Export your customer list as CSV from Service Fusion and import it into ClientForge; your customer list is live the same day.
Does Service Fusion have a free tier or trial?
We could not confirm a free tier on their public pricing page. EternalEngine Free is one user with the full CRM, 5 invoices and 5 estimates a month, no card and no time limit; every paid plan adds a 30-day free trial.
