Built for tradespeople & subcontractors
Get paid for every change to the job.
Vallio helps you raise variations, get them signed off on the spot, and keep track of what you're owed — built for people who work with their hands, not spreadsheets.
Free plan · No card needed · 7-day free trial on Pro, then £49/month.
Everything your QS does — without the wait.
1
Variations
Raise a variation the moment extra work comes up. The client signs off on the spot, before you start.
2
Valuations
Track your progress and send valuation reports — CIS and retention handled for you, automatically.
3
Dispute Protection
Every signed variation builds a paper trail. If a client disputes it, one tap gets you a full dispute pack.
The tools a quantity surveyor would charge you for.
1
Scope Checker
When a client says 'that was always in the price', paste their claim and get an instant QS verdict, with the reasoning and their strongest counter-argument.
2
Letter Generator
Construction Act-compliant payment notices, 7-day chasers, and dispute letters — written for you, no solicitor needed.
3
Risk Assessment
An honest read on how strong your position is on any variation, and what evidence to gather.
How It Works
Raise it — log the extra work on site, in seconds, from your phone.
Get it signed — the client approves it digitally before you start.
Stay covered — your paper trail and cost position build themselves.
Simple, honest pricing.
