EVIDENCE
Your team approves before anything ships.
Every cost points at its source. Every cost links back to the estimate, purchase invoice, labour record, or variation that produced it.
Every alert is reviewable. Your commercial lead reviews alerts before they become decisions.
Every allocation leaves a trail. Invoice allocations, edits, and approvals are timestamped and traceable.
