Best Free FSM Software & Free Trials (2026)

Searching for free FSM software? Here is the honest version: exactly one full-featured platform offers a permanently free plan — ServiceM8, for a solo operator on an iPhone, capped at 30 jobs/month. For everyone else, what you can get is a generous free trial and a very cheap entry plan. These are the best ways to start at little or no cost.

Beyond ServiceM8’s solo free plan, "free" tools are either trials, freemium apps too thin to run a service business, or generic to-do apps. Rather than send you to a dead end, we ranked the genuinely free option, the strongest free trials, and the lowest-cost paid entries so you can evaluate without spending much.

ServiceM8

The only genuinely free plan
from $0/mo 4.6

ServiceM8 offers the one permanently free plan in this category: $0/month for a solo operator, capped at 30 jobs/month. A genuinely part-time operator can run on it indefinitely, then step up to the $29 Starter plan (50 jobs, unlimited staff) only when volume grows. iPhone required.

Pros

  • Permanently free solo plan (30 jobs/month)
  • Paid plans from $29 with unlimited staff
  • No contract

Cons

  • iPhone/iPad-first — Android app is limited
  • Free plan is 1 user, 30 jobs/month

Jobber

Best free trial (full-featured)
from $49/mo 4.6(479)

Pros

  • Full product during trial
  • Cross-platform
  • Easy to set up fast

Cons

  • No permanent free tier

#5

Workiz

Trial for specialty trades
from $229/mo 4.5(224)

Workiz provides a 7-day trial aimed at appliance repair, locksmith, and garage-door businesses, with call tracking and lead tools you can sample before buying. The window is shorter, so plan your test runs.

Pros

  • Specialty-trade features
  • Call tracking included
  • No contract

Cons

  • Only 7 days
  • Pricing is quote-based

How we picked

  • Length and completeness of the free trial (can you run a real job?)
  • Lowest paid tier once the trial ends
  • No credit-card-required tricks or auto-upgrade traps
  • Whether the cheap tier is actually usable long term
