How to choose CLM software: the criteria that really matter

A CLM tool manages a contract from drafting to post-signature tracking. It is justified when several teams produce contracts and tracking no longer relies on a single person.

A few concrete signs help you decide:

• Several teams ask the legal department to draft or approve contracts.
• You have to ask around to find out which version is authoritative.
• Approvals are tracked in email threads.
• A notice period or a renewal has already been discovered too late.
• A simple question about the portfolio requires a manual search.

Conversely, if you sign few contracts, on stable templates and with one person tracking them, rigorous filing and an up-to-date spreadsheet may be enough. The question is then worth reopening when the volume or the number of teams changes. If you are weighing a document management tool, our article Document management or CLM explains where the line falls.

Every CLM covers several stages of the contract, but they do not all put the emphasis in the same place. Your priority therefore determines what to test first:

• Deadlines that catch you off guard. Test the migration of existing contracts, date extraction and reminders on notice periods.
• A legal team overwhelmed by simple requests. Test templates, questionnaires and what a business team can produce on its own.
• Approvals that are hard to track. Test approval workflows and how decisions are retained.
• Scattered negotiations. Test collaboration with the counterparty, change tracking and version comparison.
• Reviews that take too long. Test AI analysis, its configuration according to your policy and source verification.

Write this priority in one sentence and have the project sponsor approve it. It will serve as the tiebreaker whenever two tools look equivalent.

Coverage of the lifecycle you use. A full lifecycle only has value if you use each stage. Identify what must happen in the tool and what can stay elsewhere.

Adoption by business teams. Have a salesperson or a buyer complete a real workflow, with no prior training. Watch where they stop. A tool that only lawyers use will not reduce their workload.

The counterparty experience. Ask what an external partner sees. Do they have to create an account? Can they suggest changes? Do they receive a usable document if they prefer to work in Word?

Migration quality. Your existing contracts probably include PDFs, scans and amendments. Ask how they are imported, how the data is extracted and who checks it.

Integrations that actually exist. Distinguish what exists today from what is announced. Ask exactly what each connector does: importing contacts does not have the same scope as a full synchronization.

The licensing model. Ask who uses up a license: the drafter, the approver, the reader, the signer? The answer often determines the real scope of the rollout. Our article on the budget for a CLM details the cost items to compare.

A demo shows the most favorable case. To evaluate AI, bring your own documents, after checking what the vendor does with them and under which confidentiality terms.

• Difficult contracts. Use a medium-quality scan, a contract with several amendments and a contract drafted by a counterparty.
• Answers you already know. Compare each result with what a lawyer identified by hand, including what the tool missed.
• Verifiable sources. Each point should link back to the relevant passage, so that checking stays quick.
• Your contract policy. Check whether you can configure your rules, their severity and your fallback positions with a contract playbook.
• Human oversight. Look at who validates the extracted data and whether decisions remain traceable.

No AI can guarantee zero errors. The right question is therefore the cost of an error and how easy it is to detect. Also ask the vendor about the model used, where processing takes place, its subprocessors and any reuse of your data for training.

These topics must be handled before the decision, because they can block a project late in the process. Involve the IT department and the DPO from the start.

Subprocessing. A CLM processes personal data contained in your contracts. Article 28 of the GDPR requires the use of processors providing sufficient guarantees. It also governs the use of other processors, audits and what happens to data at the end of the service. Ask for the up-to-date list of subprocessors and the location of each processing operation.

Proof of security. A certification, a framework the vendor follows and a sales claim do not carry the same weight. Ask for the exact scope of the certificates and the penetration test report available under a non-disclosure agreement.

Requirements specific to your sector. SecNumCloud, for example, is a qualification issued by ANSSI (the French national cybersecurity agency) that covers a specific cloud offering. First identify whether a law, a contract or your internal policy requires it for the data concerned.

Reversibility. The European Data Act, applicable since September 12, 2025, governs switching between data processing service providers, and its Recital 81 cites software as a service (SaaS). In particular, it provides for a notice period of no more than two months, a default transition period of thirty days and the removal of switching charges from January 12, 2027. Ask what you will actually get back: signed files, versions, metadata, evidence files and the audit log.

An effective selection takes only a few steps, provided you limit the number of vendors and scenarios:

• Name a decision-maker. They arbitrate when legal, business teams and IT disagree.
• Describe three real scenarios. For example: a standard commercial contract, a supplier contract sent back with changes, and the migration of a batch of older contracts.
• Shortlist few vendors. Two or three are usually enough for an in-depth comparison. Our alternatives page gathers public information on several of them.
• Send the same questionnaire. Our requirements specification provides a base to adapt.
• Have them run your scenarios. Ask each vendor to walk through the same workflows in front of the future users.
• Score with evidence. For each criterion, give a score from 0 to 3 and note what you saw. A verbal answer does not earn the top score.
• Talk to references. Ask for a conversation with an organization of comparable size, if the vendor can offer one.

The last pitfall concerns scope. Trying to roll out everything at once delays the first result. Instead, ask how to start with one contract type or one team, and what it will take to expand afterwards.

Docform brings drafting, review, approval, negotiation, e-signature and deadline tracking together in one workspace, hosted in France. The AI assistant cites the source passage and the lawyer keeps the decision. The rollout can start on a targeted scope. The most useful step is still to check this on your scenarios, with your contracts.
