The pressure is increasing from both sides.
The authorization gap has always been an internal cost. It is becoming an external competitive exposure at the same time.
Write-down pressure is accelerating
90% of firms confirmed write-down increases in 2026. The loss compounds each billing cycle. Every departure takes matter context and authorization patterns with it, making the next reconstruction harder and more expensive.
Clients are mandating proof before payment
Outside counsel guidelines are expanding beyond rate caps into documented proof that billed work was authorized before execution. When a single Chief Legal Officer mandates it, every firm on that panel complies or loses the relationship. Firms that cannot produce the record get removed.
AI-powered invoice review is making denials faster and harder to fight
Corporate legal departments are deploying AI to review outside counsel invoices against outside counsel guidelines in real time. Charges that lack authorization context are being flagged and denied automatically — at a speed and volume that was not possible before. Firms that previously had room to negotiate a disputed charge now face automated deductions with no appeals process. Without an authorization record at the moment of execution, the firm has nothing to present. The denial stands.
