Builders have the opposite problem to a callout trade. Instead of dozens of small same-day jobs, you're running fewer, longer projects - with detailed quotes, variations as the scope changes, progress claims, subcontractors to coordinate and retentions to track. Job management software for builders has to handle that project length and complexity, not just quote-and-invoice. This guide covers what builders specifically need in New Zealand, and which apps fit best in 2026.
Pricing and features are accurate as of June 2026 but change often - check each vendor's website for current details. TradeFlow isn't affiliated with these products; this is an independent comparison for NZ tradies. One exception: if you sign up to Tradify through our link we may earn a referral commission - it doesn't change where it sits in this guide. (Tradify and Fergus prices are NZD; ServiceM8 is AUD; Simpro is quote-based.)
What builders actually need
- Detailed quotes and variations - itemised estimates that can be revised as scope changes mid-build, with a clear record of every variation the client signed off.
- Progress claims - invoicing a long project in stages (deposit, lock-up, fit-out, completion) rather than one final invoice, and tracking what's been claimed against the contract value.
- Subcontractor coordination - assigning and tracking subbies, their purchase orders and their costs against the job.
- Job costing across a long build - seeing budget vs actual on labour and materials over weeks or months, not a single day.
- Retentions and longer cash cycles - keeping sight of money still owed at the end of a project.
- Accounting sync - pushing claims and invoices to Xero, MYOB or QuickBooks Online.
Why ServiceM8 often isn't the fit for builders
ServiceM8 is excellent for high-volume callout and service trades - but its whole model is built around lots of small jobs. For builders running a handful of long projects with variations and progress claims, the per-job pricing and service-job structure don't match the workflow. That's why most builders land on Fergus or Simpro instead, with Tradify suiting smaller building and renovation work.
Which apps fit builders best
| Software | From (indicative) | Why it suits builders | Watch-out |
|---|---|---|---|
| Fergus | $53 NZD/mo | NZ-built, job costing, phases and purchase orders for longer projects | Less heavy-duty than Simpro for large commercial |
| Simpro | Quote-based | Multi-stage projects, takeoffs, inventory, subcontractor and asset management | Setup cost; overkill for small builders |
| Tradify | $48 NZD/user/mo | Simple quoting and invoicing for smaller builds and renovations | Lighter on progress claims and deep costing |
| ServiceM8 | $29 AUD/mo (50 jobs) | Fine for builder callbacks/maintenance arms | Built for small service jobs, not long builds |
| AroFlo | Quote-based | Field service and maintenance arms, asset management, offline field app | Geared to field service more than long new-builds |
Fergus - costing and phases for residential builders
Fergus is NZ-built and centred on job costing and profitability, with job phases, purchase orders and detailed reporting on its Professional plan - a strong match for residential builders who need to track budget vs actual across a multi-week project and coordinate subbies. Plans start at $53 NZD/month (Basic) and $75 (Professional), plus $22/month per timesheet user, with an Enterprise tier for 10+ staff.
Simpro - for larger and commercial building operations
Simpro is built for larger, complex operations running multi-stage projects, takeoffs, inventory and subcontractor and asset management - the closest fit when a build involves serious project management. Pricing is quote-based and tailored with a setup/onboarding fee, so it's an investment best suited to established building companies rather than a sole-operator builder.
Tradify - for smaller builds and renovations
Tradify suits smaller builders, renovators and handyman-style operations who want simple, fast quoting and invoicing without project-management depth. Plans run from $48 NZD/user/month (Lite) to $62 (Plus), with purchase orders and reporting on the Plus tier. It's lighter on progress claims and long-project costing than Fergus or Simpro, so it fits best where jobs are shorter.
AroFlo - for builders with a service or maintenance arm
AroFlo leans towards field service and maintenance work - asset management, compliance forms and an offline-capable field app, with two-way Xero and MYOB sync. For builders it fits best where there is a service or maintenance side to the business rather than purely long new-builds; pricing is quote-based per user. See our AroFlo overview.
How to choose as a builder
- Map your project length. Long, multi-stage builds with variations and progress claims -> Fergus or Simpro. Shorter renos -> Tradify can be enough.
- Test variations and progress claims. Run a real staged quote through each shortlisted app - this is where service-first tools fall short for builders.
- Check subcontractor and purchase-order handling. If you lean on subbies, make sure their costs flow into the job budget.
- Weigh setup vs simplicity. Simpro is powerful but needs onboarding; Fergus is a middle ground; Tradify is the quickest to stand up.
- Confirm the accounting sync. All four connect to Xero; check MYOB or QuickBooks if you need it.

Frequently asked questions
What's the best job management software for builders in NZ?
For most builders it's Fergus or Simpro, because both handle longer projects, job costing and subcontractors. Fergus suits residential builders; Simpro suits larger commercial operations. Tradify is a good fit for smaller builds and renovations.
Why isn't ServiceM8 ideal for builders?
ServiceM8 is built around high volumes of small service jobs with per-job pricing. Builders run fewer, longer projects with variations and progress claims, so a costing- and project-focused tool like Fergus or Simpro usually fits the workflow better.
Can these apps handle progress claims and variations?
Fergus and Simpro are the strongest for staged claims, variations and budget-vs-actual costing across a long build. Tradify handles quoting and invoicing well but is lighter on progress-claim workflows - trial it with a real staged job first.
Which is easiest for a small builder to start with?
Tradify is the quickest to stand up and learn. Fergus adds costing depth for longer projects; Simpro is the most powerful but needs onboarding and a tailored quote.
