Supplier contract review for procurement teams
Check a supplier's contract against your organisation's playbook. Understify lists what the contract leaves out or words differently from your positions, quotes the clause behind a finding when it finds one, and puts each proposed change in front of someone to approve or reject.
Playbook checks, approvals and exports are on paid plans. It does not give legal advice.
