The bottom line
"Unapproved variations are the #1 cashflow killer for contractors. Vector makes sure nothing stays pending — and nothing gets forgotten."
How it works
Simple by design.
Build the cost sheet
Add line items broken down by cost element — labour, materials, plant, subcontractor, or custom types.
Submit for approval
Vector notifies each approver in sequence by email with a secure one-click approval link.
Track to completion
Monitor approval status in real time. Revise and resubmit if rejected. Full history is always retained.
