ServiceM8 vs Tradify vs Fergus vs simPRO for NZ tradies (2026)

Most NZ tradies are on the wrong job-management tool. Either too cheap (still doing quotes in Word at 9pm) or too expensive (paying for a per-user tool with mid-market features when a flat-fee tool would do everything they need).

This is the no-kickback comparison: we don't resell any of these tools, so there's no angle in what follows. It's the honest version of how the four stack up once you get past the marketing pages and look at what they actually do, and what they cost you as a crew grows.

Quick verdict

Crew size	Best fit	Why
Solo, 1-2	Tradify	Simple UI, NZ-built, easy on-ramp
3-4 (most NZ trades)	ServiceM8	Flat fee for unlimited users. Mobile-first. The sweet spot.
5-8	ServiceM8 or Tradify	ServiceM8 stays cheap; Tradify gets nicer reporting. Toss-up.
8-15	Tradify or Fergus	Tradify if you want simpler, Fergus if you want NZ-specific GST/PAYE/ACC integration depth
15-50, multi-site	Fergus or simPRO	Real scheduling power, multi-branch, real project costing
50+ or commercial / industrial	simPRO	Built for it, but you will pay for it

If you are a 3-4 person crew on Fergus or simPRO, you are almost certainly overpaying and not using the features that justify the per-user pricing. Read on.

The four tools, head to head

ServiceM8, the small-crew sweet spot

• Model: Flat-fee plans, unlimited users. Free tier for solo testing. Check vendor for current pricing.
• Built for: Service trades, plumbers, sparkies, gas fitters, locksmiths, glaziers, security.
• Strengths: Mobile-first, designed for the van. Quote-to-invoice in 4 taps. Photo, voice-note, sketch attached to jobs. The unlimited-users pricing is the killer feature for crews, adding a fourth tradie is free.
• Weaknesses: Australian-built so a couple of NZ-specific quirks (GST handling is fine but ACC integration is light). The desktop UI is the weak link, you would not run a 20-person scheduling board on it.
• Use it if: You are a 1-8 person service-trade crew where the work happens off the van. Most NZ residential trades fit this profile.

Tradify, the NZ-popular default

• Model: Per user, with a solo tier. Cost scales with crew size. Check vendor for current pricing.
• Built for: Owner-operator trades broadly, service trades, light construction.
• Strengths: Beautifully simple UI. NZ-built (Auckland), so GST, PAYE and ACC handled natively. Strong Xero integration. Great support, actual humans answer the phone. Excellent for the tradie who wants a tool they can adopt without a trainer.
• Weaknesses: Per-user pricing bites at crew size 4+. Reporting is good but not deep, if you want job-cost variance reports across 200 active projects, it is not the tool.
• Use it if: You are solo or small (1-3), want NZ support, and value simplicity over deep features. Genuinely the best default for the "I just want quotes and invoices off my phone" tradie.

Fergus, the deeper NZ build

• Model: Per user, premium of Tradify. Check vendor for current pricing.
• Built for: Mid-sized NZ trades with real scheduling and project complexity. Plumbing, electrical, HVAC firms 5-30 people.
• Strengths: NZ-built (Auckland) with serious depth. GST, PAYE and ACC handled properly. A proper drag-and-drop scheduling board across multiple sites, time tracking, and job-cost variance reporting that actually holds up. Strong if you bill time-and-materials.
• Weaknesses: Per-user pricing makes it expensive for small crews. A 3-person crew is paying for advanced scheduling, project costing and T&M variance features they will probably never use. Steeper learning curve.
• Use it if: You are 5-20+ people, your work has real project complexity, and you bill time-and-materials with real variance. If you are a small crew on Fergus and only use the quote / invoice / Xero-sync features, you are overpaying for ServiceM8 features.

simPRO, the commercial / industrial tier

• Model: Quote-only, with a substantial setup fee and multi-year contracts common.
• Built for: Commercial trades, industrial maintenance, security & access, fire protection, HVAC contracting at scale. 15+ people, multi-branch, project-based.
• Strengths: Proper project management, asset and equipment tracking, multi-branch and multi-warehouse, and stock control that genuinely works. Strong preventative-maintenance and asset tracking. The right tool if you're running 20+ techs across sites or a recurring maintenance contract book.
• Weaknesses: Overkill for residential service work. The setup is a serious project (not a Sunday afternoon job). Per-user costs add up. Reporting is powerful but the UI is dated.
• Use it if: You are a commercial contractor (mechanical / electrical / fire / security / HVAC) with real scale, real assets and real recurring maintenance work. Not the right tool for residential trades.

The switch that usually pays for itself

The move that most often makes financial sense on paper: Fergus → ServiceM8 for a 3-4 person crew. The math is simple:

• A per-user tool with four users, versus a flat-fee plan with unlimited users, comes to several times the annual cost, for scheduling and project-costing features a small crew rarely touches.
• On the flat-fee plan, adding a fifth or sixth tradie costs nothing. On per-user, every hire is another monthly line.
• For a small crew that's a saving of several thousand a year, every year.

The other direction is real too: a growing crew (8+) can genuinely outgrow ServiceM8 or Tradify and need Fergus's scheduling and project costing. When the growth is real, that's the right move. Not before.

How to switch it yourself

Here's the honest bit: for a small crew, this is an afternoon's work, and you can do it without paying anyone. The rough order:

1. Trial the new tool first. Most offer a free trial. Set it up on your phone and make sure it feels right before you move anything.
2. Export your contacts from the old tool (a CSV of clients and suppliers). Download or PDF any past jobs you want for your records. Don't count on moving job history across, the two tools store it differently and it rarely transfers cleanly.
3. Connect the new tool to your existing Xero. This is the important step: Xero already holds your invoices and contacts, so most of your client list flows in from there instead of being re-typed.
4. Rebuild your quote and invoice templates in the new tool. Do it once, properly, it's fifteen minutes and it's what your customers see.
5. Recreate the recurring jobs or job templates you use often.
6. Run both in parallel for a week or two. Finish open jobs in the old tool, start new ones in the new one. Don't try to move a job that's mid-flight.
7. Cancel the old subscription once the last open job is closed out. If you're on a per-user or contract tool, check the notice period first.

One more honest tip: the tool you're moving to usually has an onboarding team who'll help you set up for free, because they want your subscription. Ask them. It's their job.

If you'd rather not

If you'd sooner spend the afternoon on the tools than in a spreadsheet, we can do the switch for a fixed fee, scoped to the job. But we'll be straight with you: for a clean small-crew move you probably don't need us, and we'll say so on the call. Where we actually earn our keep is the messy ones, years of history to preserve, custom forms, integrations wired into other systems, or a crew big enough that a day of downtime costs real money.

What we do not do

We don't resell any of these tools, and we don't take a kickback from any vendor. We're an independent NZ IT advisory: we'll help you land on the right tool, we're happy to do the switch if you'd rather not do it yourself, and either way the fee is just labour, never a hidden margin on software we're quietly pushing.
