What is Mutu?

It's a list of everything your business owns - on your phone

Every drill, ladder, trailer and half-pack of GIB, all in one app your whole crew can see. No spreadsheets, no ringing around to find out who's got the laser level.

1

Put your gear in the app

Snap a photo, give it a name, done. Tools, vehicles, machinery - anything you own.

2

Your crew finds and books it

Anyone on your team can look up what you own from site, see where it is, and book it for their job.

3

Leftovers get used, not dumped

List spare materials at the end of a job so your next job can grab them - instead of buying new.

If you can take a photo on your phone, you can use Mutu. Up to 5 of your team can be on it.

Keep track of your gear

Know where every tool and vehicle is - without leaving the ute

Mutu keeps a simple record of everything you own. Search it from anywhere, see where things are, and book what you need for your next job.

✓Toolkit check-ins

Send a check-in to your crew whenever you like - they confirm on their phone that they've still got the tools they're meant to have.

✓Theft & insurance record

A full record of your gear with photos - ready to go if something gets nicked or you need to make an insurance claim.

✓Maintenance reminders

Get reminded when your equipment and vehicles are due for a service - before they let you down on site.

✓Test & tag reminders

The app tells you when test & tag is due, so you're always compliant without keeping it in your head.

Your own internal Trade Me

Leftover materials? List them like Trade Me - but just for your business

Every job finishes with leftovers - framing timber, GIB, insulation, fixings. Usually they end up in the skip, or back at the yard where they're forgotten.

With Mutu, you take a photo on your phone and it's listed in under a minute. Everyone on your team sees it. If someone needs it on their job, one tap and it's theirs - instead of buying new.

Mutu adds up what you save. Every time you reuse materials or gear instead of buying or hiring again, the app keeps a running total - so you can see exactly what it's putting back in your pocket.
Urry + Burgess Construction NZCB member case study

Urry & Burgess tripled their monthly bookings - and reused $1,400 of materials

Urry & Burgess Construction are an Auckland building firm doing residential and commercial work - fellow NZCB members with 25+ years behind them. In early 2026 they put their tools, vehicles and materials onto Mutu.

They added 100 items in the first month. Now the whole team looks up what's available before hiring or buying anything new - and leftover materials from one job get used on the next instead of sitting in the yard.

Team members sharing the one system

"Before Mutu, information about equipment and stock could sit with different people or in different places. Bringing it together has given the team a much clearer starting point when they need something for a job." - Charlie Urry, Director, Urry & Burgess Construction
