What counts as a transaction
Adobe defines a Sign transaction as a single agreement sent for signature, and a transaction is consumed when the agreement is sent, not when it is completed. That distinction matters. A canceled or abandoned agreement still draws down your pool, so a high volume team that sends speculatively burns transactions faster than its completed deal count suggests.
Transactions are pooled and allocated against a yearly entitlement. When you exceed the pool you move into overage, and overage is priced well above your committed unit rate. This is the structural reason Sign bills tend to climb after the first year, the meter resets but the habit of overshooting does not.
Why the overage curve is the real cost
The committed transaction price is the number procurement looks at. The overage price is the number that actually drives the bill once usage grows. Adobe rarely volunteers a generous overage rate, because predictable overspend is a reliable revenue stream for them.
We model usage across a full cycle, including seasonal spikes such as year end contracting and onboarding waves, and we size the commitment to land just below peak rather than at average. Sizing to average guarantees overage every busy month. Sizing to peak wastes the commitment in quiet months. The buyer side answer sits between the two and is set deliberately, not by accident.
Levers that keep Sign predictable
First, negotiate the overage rate down to within a defined multiple of the committed rate, and put it in writing. An uncapped overage clause is an open ended liability. Second, negotiate the right to true down unused transactions at the anniversary, not just up. Third, separate Sign volume reporting so you can see consumption monthly rather than discovering it at renewal.
Consolidating signature workflows onto one platform also strengthens your position. Fragmented usage across Sign and a rival tool weakens the volume you can commit and the discount you can demand.
