What third-party guides estimate
Some 2026 buyer's guides publish estimated ranges. One vendor-agnostic guide (IXSOR) puts purpose-built per-seat review tools at roughly $30 to $400+ per user per month. It estimates full CLM deployments at $200 to $1,500+ per user per month or on negotiated enterprise terms. Treat these as rough guides, not quotes. They may leave out implementation, integrations and services.
Questions to ask before you sign
- Is pricing per seat, per contract volume, or a platform fee? Are view-only business users free?
- Are there usage caps (for example, completions per month) or overage charges?
- Which tier unlocks custom playbooks, the repository, SSO and API access?
- What do implementation, playbook-building services and integrations cost?
- What are the renewal terms, price-increase limits, and data export rights if you leave?
