Work smarter. Build bigger.
Stress less.
Spreadsheets and group chats don't cut it across multiple jobs, trades, and sites. OnSite Companion is construction project management software built exclusively for residential and commercial builders in Australia and New Zealand. Job control, workflow coordination, defect tracking, and document management: one connected platform.
Solution
One place for every job, every team, every site
Jobs run across multiple sites, trades, and supervisors with no single source of truth. Updates live in phone calls, texts, and someone's memory. A defect goes unlogged. A variation gets approved but never recorded. By the time it surfaces, the job has already slipped behind and someone is chasing the paperwork.
Know every job's status
Real-time visibility across every active job. No phone calls, no status updates, no surprises.
Stop defects eating profit
Every issue logged, assigned, and resolved against the correct job. From identification to sign-off.
Always know what's next
A personalised to-do list keeps every supervisor on track, in the right order, every time.
Coordinated Trades
Trade sequences and site activities in one place. Right people, right time, every time.
