For a legal department, the equation is often the same: too many contracts, too little visibility, a budget under pressure, and SaaS vendors who promise to solve everything for an annual licence fee.
Most of the legal departments I work with ask me the same question: which CLM should we buy? LinkSquares, Ironclad, DocuSign CLM, Luminance? Each one promises the moon, each one has its slide deck, and each one will cost far more than its list licence price once you add integration, configuration and change management.
The good news: in most of the situations I see, you do not need to buy a CLM. You already have one. You just need to switch it on.
What your Microsoft 365 already contains
The legal departments I work with sit in organisations that have run Microsoft 365 for years. It is a proven platform. It has been audited, it has passed the DPIAs and the CISO reviews. It is in production, it is paid for, and it is used for everything except the legal function.
What most people do not realise: your Microsoft 365 has the building blocks to cover most of a Contract Lifecycle Management.
SharePoint
The document layer. Not as a simple drive, but as a tool with libraries organised by contract type, custom metadata (party, value, expiry date, document type), built-in approval workflows, fine-grained access control by role, automatic versioning of every change, and search across both content and metadata.
Your team uses SharePoint to share a PDF. It can use it to run the whole life cycle of a contract.
Power Automate
The orchestration layer. This is the tool that links your SharePoint to the rest of the organisation. Receive a contract request from a Microsoft Forms form. Create a SharePoint folder with the right metadata automatically. Send the contract for signature through DocuSign or Adobe Sign. File the signed contract in the right library. Send a reminder 60 days before expiry.
All of this without code, without a new tool, and without an extra licence for most uses.
Teams
The collaboration layer. Often underused by legal teams, who stay in Outlook. Teams gives you a dedicated channel per type of matter (M&A, framework agreements, disputes), conversation threads attached to a specific document, built-in integration with SharePoint (each channel has its own library), and targeted notifications on the events that matter.
Power BI
The reporting layer. It turns SharePoint metadata into a dashboard: number of contracts by type, by month and by client, average review time by document type, contracts expiring in the next 90 days, average handling cost by category.
The data is already there. Power BI displays it.
Anatomy of a CLM on Microsoft 365
Let us rebuild the full CLM chain, one block at a time.
1. Incoming request. A salesperson needs an NDA. They fill in a Microsoft Forms form available from the intranet. Fields: counterparty, context, requested deadline, standard NDA template.
2. Automatic folder creation. Power Automate picks up the submission, creates a folder in the "Incoming contracts" SharePoint library, pre-fills the metadata and notifies the lawyer on duty.
3. Legal review. The lawyer opens the folder in Teams (which shares the SharePoint library), co-edits the NDA online in Word Online and leaves traceable comments.
4. Internal approval. If the NDA needs approval (financial threshold, unusual clause), Power Automate sends an approval task to the General Counsel, with a deadline.
5. Signature. Once approved, Power Automate sends the document for signature through DocuSign or Adobe Sign (both have native Power Automate connectors).
6. Filing. The signed document comes back to SharePoint, tagged "Signed", with its signature evidence, its effective date and its deadlines.
7. Reporting. Power BI pulls the metadata continuously to feed the General Counsel's dashboard and the indicators presented to the executive committee.
Each block already exists in Microsoft 365. The integration is native. Your data never leaves your Microsoft 365 environment.
"Don't pay twice for what you already own." Not a stance: a simple sum.
Questions to ask before you start
It is not all plain sailing. Building a CLM on M365 means answering 4 questions.
What is your Microsoft 365 licence level? E3 or E5 covers most needs. Business Standard can be enough for small teams, but it limits some advanced SharePoint and Power Automate features.
Do you have access to a technical lead? Deploying a CLM on M365 means configuring SharePoint, building Power Automate flows and connecting applications. That takes someone in charge: IT, a dedicated Legal Ops person, or an external consultant.
Is your current SharePoint a dumping ground or a library? In many organisations, SharePoint has become a chaotic file store. Building a CLM on top of it means fixing document governance first.
How large is your contract workload? For a legal department that handles a few dozen contracts a year, a CLM on M365 covers the need. For a team handling high volumes of cross-border contracts in parallel, a dedicated SaaS tool may still make sense, on its own or alongside M365.
A standard architecture in 4 blocks
Here is an architecture I regularly deploy for clients.
Block 1. Entry portal. Microsoft Forms to capture requests, split by contract type. Each form is a guided path that pre-fills the metadata of the future folder.
Block 2. Document hub. One SharePoint library per contract type (NDA, purchase order, framework agreement, distribution agreement). Standard metadata columns. Connected Word templates. GDPR retention rules configured.
Block 3. Orchestration. A set of Power Automate flows covering the common scenarios: folder creation, signature reminders, expiry notices, filing. Each flow is documented and can be maintained by an internal lead.
Block 4. Reporting. A Power BI dashboard linked to the SharePoint lists, published in Teams, available to the General Counsel and to named stakeholders. KPIs: volume, time, cost, deadlines.
What this looks like in practice
On my recent engagements with legal departments in large groups and mid-sized companies, here is what we built on the environment already in place.
NDA handling time cut from 75 to 10 minutes, or −87%, by automating triage, approval and filing. Anonymised engagement with the French subsidiary of an international healthcare group, on 20 to 40 NDAs a month: 260 to 520 hours of legal capacity that could be freed up over the year. Everything was built in Google Workspace, the environment already in place. No new CLM was needed: that is exactly the point of this article.
A complete contract chain, without a CLM. In a European B2B services group (4 lawyers, around 2,500 contracts a year), three CLMs had been assessed; none was bought. Request form, drafting, approval, DocuSign signature and filing were built in Microsoft 365, with Power Automate. Over 9 months, the cycle time for a standard contract fell from 22 to 8.7 days, and the share of requests sent by email fell from 45% to 9%.
Legal Ops reporting that produces itself: a Power BI dashboard fed continuously by SharePoint, presented to the executive committee with data from the previous day and a drill-down by business line. What goes away is the manual consolidation before every meeting.
Compliance questions answered without a lawyer: a Copilot Studio agent connected to internal documentation answers recurring questions (GDPR, code of conduct, sanctions) and cites its source. Lawyers get their time back for the questions that matter.
On these last two points, I give no percentage: I have no before/after measurement I can show.
Mistakes to avoid
Trying to do everything at once. A full CLM is built in layers. Start with a single contract type. Usually the NDA, because volume is high and risk is low. Embed good habits. Then expand.
Underestimating document governance. If your current SharePoint is a mess, the CLM you build on it will be a mess too. Restructuring it first is not optional.
Neglecting change management. A CLM on M365 gets adopted or it does not, like any other tool. One champion per team, training on real cases, follow-up after go-live: that is what separates a tool people use from a tool that sits idle.
Going it alone without a technical lead. Power Automate and SharePoint are easy to start with but take real skill to run at scale. An IT lead or a consultant for the length of the rollout avoids technical dead ends.
Where to start
3 steps to get going, without a heavy commitment.
Audit your Microsoft 365. Which licences are in place, how SharePoint is used today, how mature your Power Automate use is. A factual baseline, before any decision on tools.
Pick your priority use case. Probably the contract type with the highest volume and the lowest risk. That is where you learn and where you prove it works.
Scope a pilot. Build the first chain end to end. Measure. Learn. Expand. How long it takes depends on the size of the project: it is set during scoping, not before.
The CLM you are looking for is not a product you will buy. It is an architecture you will switch on, on a platform you have already paid for. All that is left is to start.
