The two pricing models
Both vendors meter signature volume, but they package it differently. Acrobat Sign tends to bundle into your wider Adobe agreement, which can deepen the discount if you already buy Acrobat at scale, and can also bury the Sign terms inside a larger co term deal where they are hard to renegotiate alone.
DocuSign sells signature as its core product, so its envelope based plans and overage terms are usually more transparent and its volume tiers more granular. The tradeoff is that you are managing a separate vendor relationship and a separate renewal.
Where each one costs you
With Acrobat Sign the risk is the bundle. Adobe will price Sign attractively to pull you onto a larger Document Cloud or ETLA commitment, and the headline Sign saving can be offset by a higher floor elsewhere. Read the whole agreement, not the Sign line.
With DocuSign the risk is the envelope overage and the annual uplift, both of which climb if volume is sized to average rather than peak. The honest answer is that neither is structurally cheaper. The cheaper one is whichever you negotiate harder, with a capped overage rate, a true down right, and a benchmarked unit price.
How to decide on the buyer side
If you already commit serious Acrobat volume, bundling Sign can win on blended price, provided you ring fence the Sign terms so a future renewal can still move them. If signature is your primary need and Acrobat is incidental, a standalone DocuSign deal keeps the terms clean and the leverage focused.
Run both vendors against each other on real volume. A live competing quote is the strongest lever either way, and the existence of a credible alternative is usually worth more than any single feature.
