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.
7. Legal
- Litigation and disputes.
- Licences and regulatory approvals.
Tips
- Use clear file names and an index.
- Upload final, signed versions.
- Keep a question-and-answer log.
- Disclose known issues upfront.
- Keep the data room updated after the deal for next time.
