DocuSign is the most widely used e-signature platform and increasingly a broader agreements/CLM suite. Business plans are priced per seat with an included envelope allowance (a signing transaction), and the term that most often bites is the envelope overage: once you exceed the annual allowance, additional envelopes are billed at a rate that can be materially higher than the per-envelope cost implied by the plan.
Before signing, the terms worth reviewing are the envelope allowance vs your real send volume, the overage rate, seat minimums, and the auto-renewal window with its associated price increase.
POCsheet reads a DocuSign proposal clause by clause and flags where the envelope allowance, overage rate and renewal terms diverge from what other buyers negotiate.
