Where contractors lose money

Four problems. Four tools that fix them.

01
Variations not fully recovered

Instructions given, work done, never properly valued. Margin walks out the door with no record and no claim raised.

NEC CE Manager · JCT Variation System
02
True margin unknown until it's too late

No structured CVR means you don't know your real position until the job's done and the damage is permanent.

Real-Time Margin Tracker (CVR)
03
Retention missed and unclaimed

Release dates forgotten. Cash left sitting unclaimed with no system to track or chase it down.

Retention Recovery System
04
Scope changes not captured

Work done beyond contract scope with no record, no CE raised, no compensation — invisible cost to your business.

Drawing Change Control System

BuildxChange builds the tools contractors need to stay in control of their commercial position — and get paid for everything they do.
