A data room is where investors or buyers review your documents during due diligence. A well-organised one speeds up the process and signals a well-run business. A disorganised one creates delays and doubts. This guide covers how to set one up.

Choose a Platform

Use a secure, access-controlled platform with permissions and activity logs. For early rounds, a well-organised shared drive with restricted access can work; later, a dedicated data room tool is common.

A Suggested Structure

1. Corporate

  • Certificate of incorporation, MoA and AoA.
  • Cap table and register of members.
  • Board and shareholder minutes.
  • MCA filings.

2. Financial

  • Audited financial statements.
  • Monthly management accounts.
  • Financial model and budget.
  • Bank statements and loan agreements.

3. Tax

  • Income-tax returns and assessments.
  • GST registrations, returns and reconciliations.
  • TDS returns.
  • Notices and responses.

4. Commercial

  • Key customer and supplier contracts.
  • Pipeline and customer metrics.

5. People

  • Employee list and organisation chart.
  • Employment agreements and policies.
  • ESOP scheme and grants.
  • PF, ESI and Professional Tax compliance.

6. Intellectual Property

  • Trademark and other IP registrations.
  • IP assignment agreements.
  • Litigation and disputes.
  • Licences and regulatory approvals.

Tips

  1. Use clear file names and an index.
  2. Upload final, signed versions.
  3. Keep a question-and-answer log.
  4. Disclose known issues upfront.
  5. Keep the data room updated after the deal for next time.
