Preparing to Sell Your Company: The Documents You Need

Selling a company requires three document packages: reliable baseline numbers for the valuation, an information memorandum for approaching buyers, and a complete data room for due diligence. Sellers who build these packages before the process starts shorten the sale by months — and avoid price reductions caused by open questions.

The need is real: in Austria alone, around 52,500 businesses face a handover between 2025 and 2034, according to KMU Forschung Austria. Buyers can choose. A seller who compiles documents only on request signals the opposite of professionalism.

This overview complements the preparation timeline with the document level: what has to be ready, and when?

Which documents does a buyer ask for first?

Before any detail come the baseline numbers. Without them there is neither a serious valuation nor a first conversation at eye level.

The last three annual financial statements. A current management report. A plan for the next two to three years. Plus the normalisation schedule: one-off effects, market-rate owner compensation, private items — cleanly adjusted and documented.

These numbers carry the valuation and, later, the information memorandum, the central document of the buyer approach.

What belongs in the data room?

The data room is the structured repository of all documents relevant to the review — today practically always digital. It opens during due diligence; it is built beforehand.

Category	Typical documents
Financials	Annual statements, management accounts, plan, normalisations, bank liabilities
Corporate & legal	Articles of association, commercial register extract, resolutions, participations
Customers & contracts	Top customer contracts, supplier contracts, framework agreements, T&Cs
HR	Anonymised employee list, template contracts, pension commitments, bonuses
Tax	Assessments, audit reports, pending proceedings
Operations	Leases, permits, insurance, IT and licence agreements, IP rights

Completeness beats polish. A missing lease stands out more in a review than a sober folder structure.

In what order do you release documents?

In stages — discretion is part of the value. If a sale becomes known too early, it unsettles employees, customers and suppliers.

Before the NDA, a prospective buyer receives only an anonymous short profile. After the signed confidentiality agreement follows the information memorandum. The full data room opens only for serious bidders after an indicative offer — and sensitive details such as customer names often only shortly before signing.

What happens if documents are missing or inconsistent?

Three things, all expensive. Due diligence takes longer because follow-up requests set the pace. The buyer prices in uncertainty — as a discount or through tighter warranties in the purchase agreement. And in the worst case, trust tips: whoever seems disorganised on small things raises doubts about the big ones.

Sellers who want certainty have their own documents reviewed in advance — as a vendor due diligence in smaller or larger scope.

Which documents do I need for a company valuation?

Three annual financial statements, current management accounts, a plan and the normalisation schedule. That is enough for a well-founded initial valuation; everything else concerns the later review phase.

How long does it take to build a data room?

With orderly records, a few weeks; otherwise several months. The most common time sink is missing or verbal-only contracts that first have to be formalised.

Do I have to disclose customer names?

Not at the start. Customer structures are first presented anonymised (e.g. "Customer A, 18 % of revenue"). A buyer typically sees real names late in the process — after NDA, indicative offer and advanced negotiations.
