The data room: preparing documents for a transaction

When a company prepares for a sale, a capital increase or the entry of an investor, the counterparty will want to verify the numbers. This verification is called due diligence, and the tool used to carry it out is the data room: an orderly archive — today almost always virtual — that gathers all the company’s relevant documents. A well-prepared data room speeds up the transaction and strengthens trust. A disorganized data room raises doubts and lowers the valuation. Let’s see how to build it well.

What it really serves for

The data room has two functions. The first is practical: to give the investor or buyer orderly access to the documents in order to carry out the checks. The second is psychological and negotiating: a company that presents complete, coherent and well-structured documentation conveys solidity and reduces perceived risk. Every question the data room answers without friction is a point in favour of the seller.

The guiding principle is organized transparency: showing everything that is needed, in a way that is easy to find and to verify.

How to structure the data room

An effective archive is organized by thematic areas, with a clear folder structure and an index. The typical sections:

• Corporate: up-to-date articles of association, extract from the commercial register, share/quota ledger, minutes of the general meeting and of the board, shareholders’ agreements.
• Financial: financial statements of recent years, income statements, any audit reports, budgets and plans.
• Tax: tax returns, VAT statements, any rulings with the authorities, withholding-tax and social-charge situation.
• Contracts: contracts with key clients and suppliers, leases, licences, financing and leasing.
• Personnel: employment contracts, regulations, pension plan (BVG — occupational pension), key positions.
• Intellectual property and IT: trademarks, patents, software licences, data-protection matters.
• Legal and litigation: any ongoing lawsuits, guarantees given, potential disputes.

What must not be missing

Some documents are always required and their absence slows everything down: up-to-date articles of association and extract from the commercial register, financial statements of the last three years, tax and VAT situation in order, main contracts. If the company exceeds CHF 500,000 in turnover and therefore has the obligation of full accounting, the coherence and quality of the accounts are the first element the counterparty examines.

Equally important is that the documents are coherent with each other: balance-sheet figures that match the VAT statements, a shareholder ledger aligned with the commercial register, contracts actually signed. Inconsistencies are what erode trust more than any low figure.

The most common mistakes

Preparing it at the last moment. Gathering years of documents under pressure leads to gaps and disorder. Preparation should begin well in advance.

Hiding the problems. Due diligence almost always brings them out. A problem anticipated and explained can be managed; a problem discovered by the counterparty destroys trust and can blow up the deal or lower the price.

Giving indiscriminate access. Not all documents should be shown to everyone at the same time. The most sensitive data (client lists, personnel data, know-how) is shared in advanced phases and with those who have shown seriousness.

Neglecting data protection. A data room contains personal data of clients and staff. Sharing it requires attention to the new Swiss Data Protection Act (nFADP): controlled access, traceability of who sees what, and — where appropriate — anonymization of data not needed for the verification.

Why the tool matters

A serious virtual data room offers access control per individual user, a log of who consulted which documents, watermarking and read-only permissions. This protects sensitive information and, at the same time, gives the seller proof of having managed the sharing diligently. A simple exchange of files by email offers none of these guarantees.

How we work

SIH ONE is an AI-native fiduciary group: we support companies in preparing the data room ahead of a sale, a capital increase or the entry of an investor, from collecting and ordering the documents to the preliminary check of their coherence, through to setting up controlled, data-protection-compliant access. Arriving at due diligence with the documents in order is the simplest way to protect the valuation.
