Due diligence data room FAQs

What should be in a due diligence data room?

A due diligence data room is typically organised into sections covering corporate/structure, financial, tax, legal & compliance, commercial, people/HR, and intellectual property & IT. Each section holds the documents a buyer or investor needs to verify the business. Using a consistent folder structure (an 'index') makes the room easy to navigate and signals you're well-prepared.

What is a data room index?

A data room index is the folder structure and document list that organises a data room, effectively the table of contents. A clear index (like the seven sections in this checklist) helps reviewers find documents quickly and is itself a sign of a well-run process.

How do I set up a due diligence data room?

Create a secure data room, build the folder structure from a checklist like this one, upload your documents (AI can auto-tag and make them searchable), set per-person and view-only permissions, gate access behind an NDA, then invite the buy-side team with identity-verified links. Track every view in the audit trail.

How long does it take to prepare a data room?

With a checklist and a tool that lets you drag-and-drop and auto-organise, an initial room can be stood up in a few hours; the longer task is gathering and reviewing the underlying documents. Starting early and using a standard index saves significant time during the deal.

Is a free trial enough for due diligence?

For a small deal that closes within 14 days, ShareAndGo's free trial (full audit trail, recipients free) can be enough. Larger or multiple concurrent deals benefit from the paid tiers' extra rooms, storage, team seats and AI search.
