TROJAN is the simple construction management app built for small UK contractors. Estimates, invoices, job tracking — all in one place.
No credit card. No contract. Free for your first 6 months.
The problem
Most small contractors are brilliant at the work but burning hours on admin that doesn't earn them a penny.
Hours at the kitchen table working out materials, labour and markup — just to win the job.
Clients sit on invoices. You're too busy on site to follow up. Cash flow suffers.
You finished the job but have no clue if you actually made money on it after materials and labour.
Notes in your phone, invoices in email, quotes in WhatsApp. Nothing connects and stuff falls through the cracks.
What TROJAN does
One app. No faff. Built for tradespeople, not accountants.
Build accurate quotes in minutes using real material prices and your own labour rates. No more guesswork.
See every live job at a glance. Track progress, notes, photos and subcontractors — all in one place.
Turn a completed job into a professional invoice in seconds. Chase late payments automatically.
Know exactly what you made on every job — materials, labour, overheads — so you quote better next time.
Assign work to your lads or subcontractors. Everyone knows where they need to be and what they're doing.
Designed for the van and the site hut — not just an office desk. Fast, mobile-first, works offline.
How it works
No lengthy setup. No training courses. Just sign in and go.
Enter your labour rates and markup preferences once. TROJAN uses them on every quote automatically.
Pick the job type, add the scope and materials. Your quote is ready to send to the client in minutes.
Track progress as you go. When it's done, fire off the invoice. Get paid faster, every time.
I used to spend half a Sunday pricing one job. Now I'm doing three quotes in the time it used to take me one. And I'm actually winning more work because I'm getting back to people faster.
