Four tools cover most Kiwi trade businesses: Tradify, Fergus, ServiceM8 and NextMinute. Below is what each one is good at, where it frustrates people, and the fifth option the comparison sites skip. If you're here because Xero retired WorkflowMax, that transition has its own guide: WorkflowMax is gone, your next tool doesn't have to be another subscription.
At a glance:
- Tradify: easiest to learn, from ~$48/user/month +GST.
- Fergus: best job costing and profitability reporting, from ~$53/month +GST for its base plan, not a per-user rate.
- ServiceM8: priced by job volume with unlimited users, suits high-volume service trades.
- NextMinute: simplest option for residential construction trades, priced by crew from ~$199/month +GST for three to nine people, free onboarding.
- None of them fit at least 90% of how you work? Build one around your own business instead.
Most tradies should buy off the shelf
If you're a sole trader or a small team and you want quotes out the door, jobs scheduled, and invoices into Xero without double entry, an off-the-shelf product will do that today, for the price of a coffee a day. Start there. Custom is for when those products keep almost-fitting and never quite get there, which I'll come back to.
The four that matter in NZ
I build custom tools and I resell none of these four, so the table below is a market read: what Kiwi tradies and reviewers consistently report. The part I've lived myself is the third option, further down.
| Tool | Built for | Strong at | Watch for | From |
|---|---|---|---|---|
| Tradify | Sole traders & small teams (1–5) | Easy to learn, tidy mobile app, strong Xero sync. The most widely used in NZ for a reason. | Reviews describe it as pricey for what you get, with limited reporting and a few scheduling-automation gaps. Bought by the UK's Access Group in October 2024, so no longer NZ owned. | ~$48/user/mo +GST |
| Fergus | Growing trade businesses (2–15) | Job costing, progress claims and profitability reporting. NZ-built. Best when knowing your margin per job matters. | Steeper learning curve than Tradify. More than a one-person operation usually needs. | ~$53/mo +GST (base plan) |
| ServiceM8 | Service trades (plumbing, electrical, HVAC) | Field-first workflow, dispatching multiple staff to jobs, maintenance contracts. Priced by job volume, not users. | Australian-built. The per-job pricing can bite if your job count is high but values are low. | by job volume |
| NextMinute | Smaller residential construction trades | Purpose-built for Kiwi builders, carpenters, landscapers, roofers. Simpler than Tradify or Fergus. Priced by crew, not per seat, so adding people doesn't move the bill. Free onboarding. | Fewer advanced features once you outgrow the basics, and the crew bands mean a two-person outfit pays the same as a nine-person one. | ~$199/mo +GST (3–9 crew) |
Run the quick version: if you want the easiest thing that works, Tradify. If margin-per-job is the number that keeps you up, Fergus. If you're dispatching staff to a high volume of service calls, ServiceM8, and I've broken its job-tier pricing down in what ServiceM8 actually costs once your crew grows. If you're a residential builder who wants something simple, NextMinute, or its Australian rival Ascora if you're comparing both, covered in Ascora or NextMinute. Any of them beats running the business out of a notebook and a glovebox full of dockets. Still torn between the front two? I go deeper in Tradify or Fergus. Already running two of these and want the annual figure rather than the monthly sticker, the stack cost checker adds them up at your crew size and job volume.
What about SimPRO? And GeoOp?
Two names come up in every comment thread that aren't in the table, for opposite reasons. SimPRO sits above this comparison rather than in it: a project platform for staged commercial work, maintenance contracts and stock, sold as a scoped implementation with no published pricing. If your jobs behave like projects, that's a real option, and the job-versus-project line is drawn out in SimPRO or Tradify. If they don't, it's weight you'd pay for and not use.
GeoOp now belongs in the past tense: bought by the same Access Group that owns Tradify, closed to new users, and winding down. Don't adopt it, and if you're still on it, the migration guide covers where NZ crews are landing and what to export before you cancel.
Where every one of them leaves the same hole
They're all built for the average trade business, and in the ones I've scoped they land around 70% of the way. The remainder is the part that's yours: the way you price a job, the checklist your crew runs on site, the report your accountant keeps asking for that the product can't produce, the second app you bought because the first one couldn't do scheduling the way you work.
So you end up paying for two or three subscriptions that don't quite talk to each other, and doing the joining-up yourself. The version that costs the most hours goes like this: you measure on site, build the quote in Excel or Word, email it as a PDF, win the job, then retype the whole thing into Xero to invoice it. Every retype is time you don't have and a chance to fumble a number. If that loop is your daily reality, there's a separate guide on killing the retype into Xero. If the slow bit is earlier, getting the quote out the door in the first place, that's a different fix, covered in what automates around a quote without touching the number.
The owners I've sat with put it at 10 to 15 hours a week on admin like this, most of it after hours. You're on the tools all day, then doing quotes and invoices at the kitchen table at night. That's the cost the sticker price doesn't show.
The third option: build it around you
If the off-the-shelf tools keep almost-fitting, there's a path the comparison sites skip because they're selling subscriptions: have the tool built around how you work, on top of the Xero you already pay for.
I've done this for my own business. I built an overnight pipeline that finds and scores Canterbury leads while I sleep, one run turns 1,579 businesses into 355 worth calling, and it can't be retired, repriced or acquired out from under me. Yours would be built around your own bottleneck rather than mine, but the economics are the same shape: a bigger cost upfront, then no per-user fee climbing every year. It usually pays for itself against the subscriptions somewhere in year two or three. After that it's yours. I break the numbers down in what custom automation actually costs.
And to be clear about the cheap end of this market: you'll see offers for a "custom app in 48 hours from a few hundred dollars". Be careful. A throwaway app with no real integration into your accounting and no one to ring when it breaks usually costs you more than it saves. Built well, it connects to the tools you already run and gets handed over so you own it.
How to choose: the 90% test
One question settles it. Pick the off-the-shelf product closest to how you work and ask: does it fit at least 90% of what I do?
- Yes? Buy it today. Custom would be a waste of money. Take Tradify, Fergus, ServiceM8 or NextMinute and get on with it.
- No, it's more like 70% and the gap costs me real hours? That's the point where building around your workflow stops being the expensive option.
Who should NOT build custom
Three cases where I'd tell you not to:
- If a product fits 90% of how you work, buy it. Custom is for when everything almost-fits.
- If your processes change every few months, wait until they settle. A custom tool fits a known shape.
- If nobody in the business will own it, don't. You need one person who cares that it keeps running, even if they never touch the code.
What I'd do in your position
Run the off-the-shelf product that fits closest for a full month, properly, with your real jobs in it. If it passes the 90% test, you're done and you've spent almost nothing. If you keep hitting the same wall and the workaround hours are piling up, that's worth a conversation. I'm Christchurch-based, and the custom layer where the off-the-shelf tools stop is the work I do. If you want the margin picture before you decide anything, Power BI against a spreadsheet for job profitability is the companion piece.
