Making OneDrive and SharePoint Actually Work for Deal Teams

Every boutique advisory firm with a Microsoft 365 subscription already has access to OneDrive and SharePoint. Most use OneDrive as a cloud-synced file dump and SharePoint as something they've heard of but never configured. The result is deal documents scattered across personal drives, email attachments, and desktop folders — with no consistent structure, no version control, and no access management worthy of the name.

The irony is that OneDrive and SharePoint, when properly configured, can handle 80 percent of what advisory firms need from document management. The problem isn't the tooling. It's the implementation.

The folder structure problem

Most firms let folder structures evolve organically. One partner creates folders by client name. Another creates them by year. A third uses a hybrid of both. Within six months, nobody can find anything without asking someone, and the firm's institutional knowledge lives entirely in the heads of the people who created the folders.

The fix is a standardised deal folder template that's automatically provisioned when a new mandate is created. Each mandate gets an identical structure — engagement letters, NDAs, financial information, due diligence materials, process documents, and correspondence — with subfolders that match the deal lifecycle. When anyone on the team opens a mandate folder, they know exactly where to find what they need.

Access control that actually works

SharePoint's permission system is powerful but poorly understood. Most firms either share everything with everyone or don't share at all. For deal work, the right model is mandate-level permissions: each deal folder is accessible only to the team members assigned to that mandate, with the ability to grant time-limited external access for specific documents when needed (e.g., sharing a CIM with a prospective buyer).

This isn't just good practice — it's a compliance requirement for most advisory firms. When a regulator or client asks who had access to what, you need an answer that's more credible than 'everyone in the firm could see everything.'

Version control without the pain

OneDrive's built-in version history is underused by almost every advisory firm we've worked with. It automatically tracks changes to Word and Excel files, allowing you to view, compare, and restore previous versions. For deal documentation — where 'final_final_v3_ACTUAL.docx' is a genuine filename pattern — this eliminates the version confusion that wastes hours per week across a deal team.

The best document management system for most advisory firms isn't a new product. It's the one they already pay for, configured properly.

Integration with deal workflow

The real power of OneDrive and SharePoint for advisory firms comes when document storage is integrated with deal workflow. When a new mandate is created in your deal platform, the corresponding OneDrive folder is automatically provisioned with the right structure and permissions. When a document is uploaded, it's automatically tagged to the relevant mandate. When someone searches for a file, they search within the context of a deal — not across the entire firm's document library.

This integration turns OneDrive from a passive storage layer into an active part of the deal process. It's the difference between having a filing cabinet and having a filing system.
