ChangeLock™ — nothing changes without approval
Scope is versioned and locked. The only way to move it is a priced variation with cost, programme impact and evidence, approved by the client in three taps and written to the permanent record.

Version-bound sign-off
On the tools, not in a spreadsheet
Priced on site, approved from the kitchen table
A variation starts where the change happens — a photo, a note and a price from the tablet in the van. The client sees the same version, approves it, and the contract sum, forecast and programme update themselves.
Follow one variation, start to finish
Raise, price, approve, lock — step through a real bi-fold upgrade and watch the contract value move with it.
Follow one variation from a request on site to a signed change in the contract value.
Step 1 of 4
ChangeLock™ · Raise
The change is captured before the work starts
A client asks for wider bi-folds on site. The variation is raised in seconds with the request, the photo and the drawing reference attached — not scribbled on a dayworks sheet.
VO-004 · Bi-fold door upgrade
Raised
“Client would like the 3m bi-fold swapped for the 4m unit with slim frames.”
Locked to the project record the moment it is raised — no work proceeds until it is priced and approved.
