WorldCC and Ironclad, examining post-signature contract performance, found that organizations lose an average of 11% of contract value after signature. The range is the instructive part: best-in-class organizations hold leakage near 3%, while the weakest performers lose 15% to 20% across the agreement lifetime. Unauthorized or unrecorded changes and poorly planned renewals each account for roughly two to three percentage points of that loss, which locates the failure in governance rather than in negotiation.
Pricing leakage and discount leakage appear as separate lines in the pocket margin walk, $1.2M and $0.8M respectively, because they are measured separately. Operationally they are the same failure observed at two points: an authority structure that permits concessions to accumulate without any single approver seeing the accumulated position.
Drift is not a decision
No individual concession moves realized price below floor. A rate exception clears at the deal desk. A payment-terms extension clears in finance. A freight allowance clears in logistics. A promotional accrual clears in marketing. Each is approved by a party with authority over its own dimension and visibility into no other. The composite position is never assembled, and by renewal the account transacts materially below the terms it was signed at.
No single concession is wrong. The account is priced by the sum of them, and nobody signs the sum.
Where latency compounds it
Approval latency is itself a discount mechanism. A quote held in a pricing exception queue loses win probability daily, and the standard recovery is a further concession to save an aging deal. The organization pays twice: once in the original margin, once in the rescue discount that latency made necessary.
The horizontal chain
Sales → Finance → Realized Margin. Exceptions verified manually over days convert routing delay into pricing concession, with realized margin landing below standard by a quantum no one authorized.
Commercial → Service → Renewal. Concessions granted as one-time exceptions persist into the contract record by default and reset the baseline against which the next negotiation opens.
The control point
Two structural controls close most of this: a discount-authority matrix with automatic stacking caps, so the composite concession is evaluated rather than its components; and rule-bound pricing guards embedded at quote configuration, so floor violations are prevented at entry rather than detected in reporting.
Price integrity is not a negotiation skill. It is an authority architecture, and it fails at the seams between approvers rather than at any one of them.
