The sale of a business rarely starts with the purchase agreement. It starts with the question of whether your own documents will stand up to scrutiny. On the buyer’s side every document is read, compared and assessed. Whatever is missing or contradictory costs time, and in the end often money.

This article describes how to prepare a data room and which mistakes tend to recur in practice.

At a glance
  • Preparing the data room starts months before the first conversation with potential buyers.
  • A review of your own before the sale reveals weak points while they can still be fixed.
  • A fixed structure and clear responsibility for follow-up questions shorten the negotiations.
  • Raising gaps yourself is usually cheaper than having them discovered during due diligence.

Why the data room shapes the process

At first the buyer knows the business only through its documents. The data room is therefore the basis for the valuation, for the warranties in the purchase agreement and for deciding which risks are reflected in the price.

An incomplete data room leads to long lists of questions. Every follow-up delays the timetable and gives the other side an opportunity to ask for a price reduction or additional guarantees. A complete and logically ordered data room, on the other hand, shows that the company knows its own affairs.

Time matters too. Interested parties often review in parallel, and their advisers work to fixed budgets. If essential documents are missing in the first days, a view forms on an incomplete basis, and that view is hard to correct later.

Reviewing your own business first

Many sale processes begin with a review carried out by the seller’s own advisers, often called vendor due diligence. The first aim is not a report for interested parties. It is to identify weak points early.

Typical findings include contracts that require the other party’s consent if the shareholders change, missing resolutions from earlier years, or intellectual property registered in the name of individuals rather than the company. Much of this can be put right before the sale. Once negotiations have started, the same correction becomes a point to negotiate.

It is therefore important to start the review early enough. Some corrections take time, for instance when contractual partners have to consent or resolutions have to be passed after the fact. A lead time of around eight weeks before the sale process starts has proved workable.

These figures describe a typical process for a mid-sized company. Depending on its size and the number of subsidiaries, the effort can differ considerably.

Structure and content

An index that follows the logic of a legal review has proved its worth: company and governing bodies, shareholdings, material contracts, employees, real estate, intellectual property, IT and data protection, litigation, financing and insurance. Each category receives a fixed number that stays the same throughout the process.

The index should contain more than folder names. A short note for each category on what is included and what is deliberately missing helps. Nobody then has to guess whether a document does not exist or simply has not been uploaded yet.

What belongs in each category

What counts is the current, signed version of a document with all amendments. Drafts and unsigned copies lead to questions. Where there are a great many customer contracts, a selection by revenue or term is often enough, provided the selection criteria are disclosed openly.

Personal data also deserves attention. Employment contracts and payroll lists are usually provided in redacted or summarised form at first. Which information is disclosed at which stage should be decided in advance and aligned with data protection requirements.

Handling follow-up questions

Opening the data room starts the question phase. A useful procedure gives each question a number, a person responsible and a deadline. Answers are recorded in writing and linked to the relevant document.

Every answer to a follow-up question can reappear later in the purchase agreement. It deserves the same care as a contract clause.

In practice, a small group within the company that distributes questions internally and approves the answers works well. This keeps different departments from giving different information, and management retains an overview of what has been disclosed.

It also helps to have a rule for questions that cannot be answered straight away. A brief holding reply with a realistic date works better than silence. It shows that the question has arrived and is being dealt with.

Disclose rather than be surprised

No business is free of risk. For the course of a negotiation, what matters is less whether there are weak points than when and how they become known. Whatever the seller raises and explains can usually be dealt with in a factual way, for example through a specific provision in the agreement or an adjusted timetable.

If a problem is only discovered during the review, however, the other side quickly asks what else might be missing. Careful preparation is therefore also a question of credibility. It does not begin with the first interested party, but with the decision to think seriously about a sale.
