Where margin disappears

Manual Process
  • Hours spent comparing drawings
  • Missed changes buried in revision packs
  • Human error in quantity takeoffs
  • Poor evidence for claims
  • Notice periods expire
Result: £100k–£400k lost per £10M project
VS
With Varix
  • Seconds to compare thousands of drawings
  • Every change highlighted automatically
  • Accurate AI-powered quantities
  • Court-ready evidence packs
  • Time-bar deadline alerts
Result: Catch missed variations, protect margins

"Between Rev 114 and Rev 121, there were 63 changes. 4 were claimable. The rest got missed as 'coordination.' That's profit left on the table."

— Senior QS, Major UK Contractor
