Construction software that connects every site to the office
We build the site apps, approvals, and cost tracking that show you what is happening on every project today, not at month end. Site teams report from their phones, the office sees costs early, and nothing waits for a signature in someone's inbox.

At a glance
What we build
We build site apps, project and cost tracking, purchase approvals, document control, and reporting for builders, contractors, and developers.
Problems we solve
Sites run on paper and phone calls, costs surprise the office too late, and drawings and approvals go missing.
Who we serve
General contractors, specialist subcontractors, developers, and building services firms.
How to choose
Start with what costs you most, usually site reporting or purchase approvals, and connect it to your accounts.
What is different
Why construction needs software built for the site
A construction business is many temporary factories running at once, each with its own team, suppliers, and problems. Information travels from site to office by phone, photo, and paper, and arrives late. By the time a cost overrun shows up in the accounts, the money is spent.
Generic project tools were designed for desks, not muddy boots and poor signal. We build apps that work offline with gloves on, and connect them to the systems the office already uses.
The aim is simple: every project leader sees the truth about cost and progress every day.
Subcontractors and suppliers are part of the picture too. When orders, payment applications, and documents move through one portal, disputes drop and everyone works from the same record of what was agreed and delivered.
Typical projects
Construction projects, costs, and timelines
Contractors usually start with the workflow that leaks most money or time.
| Project | What it includes | Typical cost | Typical timeline from approved scope |
|---|---|---|---|
| Site diary and reporting app | Daily reports, labor, delays, and photos, offline | $12,000 to $24,000 | 4 to 6 weeks |
| Purchase approvals | Routing, mobile approvals, and orders created in your accounts | $8,000 to $20,000 | 2 to 4 weeks |
| Cost tracking dashboard | Budget, committed, and actual cost by project | $12,000 to $28,000 | 4 to 6 weeks |
| Full project platform | Diaries, approvals, documents, safety, and a subcontractor portal | $40,000 to $96,000+ | 2 to 4 months |
Every project is quoted in writing after a short call. The top of each range covers larger builds and more integrations. The timeline starts once the scope is approved and we have what we need from you.

What clients say
Teams like yours, in their own words
Missed confirmations used to leave gaps in the diary that we noticed too late. The reminders now go out on schedule, and the team can see which patients still need a call.

Common questions
Questions about construction software
How much does a construction app cost?
A site diary or approvals app usually costs $12,000 to $28,000 and takes 4 to 6 weeks. A full project platform costs more and is built in stages.
Will site teams actually use it?
They do when it saves them time. We design with site managers and keep every task to a few taps.
Does it work without signal?
Yes. Entries are saved on the phone and sync automatically when a connection returns.
Can you connect to our accounting system?
Usually, yes. Orders, invoices, and costs flow between the app and your accounts automatically.
Can subcontractors use it?
Yes. Subcontractors get their own portal for orders, payment applications, and documents.
Can we capture photos and sign-offs on site?
Yes. Site teams take photos, record signatures, and complete checklists in the app, and everything is filed against the right project automatically.
