What documents do you need to sell a business? What to prepare and when

To start preparing a business for sale, you need financial statements for recent years, an up-to-date income statement and balance sheet, a breakdown of debt and cash, and key information about sales and the organisation. Contracts, tax records and employee information are collected and reviewed progressively, according to the characteristics of the business and the stage of discussions with buyers.

Business owners do not need to have everything ready before speaking to an adviser. They should, however, know which information is available, what needs updating and what is missing. This initial review helps establish the preparation work required and whether the business can be presented using reliable information.

Collecting documents and sharing them follow different timelines. An important contract may need to be reviewed immediately by the seller’s advisers, even if the buyer will only receive it during a later stage.

Documents for an initial valuation

Financial statements help establish how the business has performed, but they need to be supported by information explaining its current position. If the last financial year ended several months ago, revenue, margins, debt or the order book may have changed since then.

A useful starting point is to collect:

• complete financial statements for recent years, typically three, together with supporting accounting records
• an up-to-date income statement and balance sheet, with a clear reporting date
• a schedule of borrowings, cash balances, leases and guarantees provided
• details of trade receivables, trade payables and inventory, where relevant
• revenue by customer and, where available, by product, service or market
• an organisation chart and details of the ownership structure.

The finance team and accountant prepare the accounting information, while the owner and managers help explain operations, customers and the organisation. Any exceptional costs, changes in trading or deferred investments should be identifiable and supported by evidence.

Provisional accounts can be used, provided it is clear which entries or adjustments are still outstanding. Comparisons with the previous year should also cover equivalent periods, particularly in seasonal businesses.

The information must reflect what is being sold

Before examining the figures in greater depth, the scope of the transaction needs to be clear. A sale may involve the shares in the company or a specific business activity, with property or other assets included or excluded.

Consider a company with two business lines whose owner intends to sell only one. The company’s overall accounts may not show the performance of the part being sold. It may be necessary to separate revenue, costs, employees, contracts and assets, while explaining how shared resources are allocated.

Similar questions arise when a business operates from premises owned by the family or trades with other companies connected to its shareholders. These arrangements need to be understood to establish the terms on which the business could continue operating after the sale.

What to prepare before approaching buyers

Once the information and transaction scope are clear, the presentation materials can be developed. The adviser uses the information collected to describe the business, its offering, performance and prospects, checking the content with the owner and the people who prepared the underlying data.

This stage also requires information that may be held across different departments. The sales manager can explain the sales mix and confirmed orders. The production manager can clarify available capacity and investment requirements. The owner helps explain the role of key people and the direction of the business.

The outlook needs an identifiable basis. A confirmed order, a sales negotiation and a revenue target represent different levels of certainty and should be presented accordingly. If there is no structured budget, this should be addressed during preparation, without turning general expectations into apparently precise forecasts.

Preparing a business for sale also means connecting these pieces of information so that buyers can understand what drives performance and what conditions support future growth.

What information to share in the early stages

Initial contact can be made through an anonymous profile outlining the sector, approximate size and essential characteristics of the business. The description should give the recipient enough information to assess potential interest while limiting details that would make the company immediately recognisable.

As discussions progress, and once confidentiality agreements are in place, more detailed information about operations, performance and the organisation can be shared. To explain customer concentration, for example, it may initially be sufficient to show the proportion of revenue generated by the largest customers without identifying them.

A confidentiality agreement does not automatically make it appropriate to disclose every piece of information. Customer names, pricing, commercial terms and personal data require specific consideration, particularly when the potential buyer is a competitor. The level of detail should reflect the actual needs of the discussion.

Documents to collect for due diligence

As the transaction progresses, the buyer needs to verify the information received. Documents supporting the financial figures, contractual commitments and operational characteristics of the business therefore become necessary.

Depending on the business, these may include accounting and tax records, customer and supplier contracts, financing agreements, employment documentation, ownership records and information about disputes. Authorisations, certifications, property documents, trademarks, patents or technology licences may also be relevant.

Key contracts should be identified during preparation, including their schedules, amendments and renewals. If an essential commercial relationship contains terms that could affect the sale, these should be reviewed promptly with the relevant advisers.

The finance team, legal advisers, employment advisers and technical managers contribute within their areas of responsibility. The M&A adviser coordinates requests and the organisation of the confidential document repository, while an internal contact oversees collection and updates.

Check documents before sharing them

Before information is shared, the reports should be checked for consistency and brought up to date. Each document should carry a date and make it possible to identify the source of the information.

If a sales report by customer does not match revenue in the financial statements, the difference needs to be explained. It may arise from credit notes, different reporting periods or classification methods. Reconciling the figures makes it possible to answer questions without producing contradictory versions.

A practical starting point is a list of available documents showing what is missing, who will prepare it and by when. This distributes the work rather than leaving every request with the owner.

Conclusion

Preparing the documents needed to sell a business means progressively building a body of verifiable information. The process starts with the data needed to understand the company, develops into materials for buyers and extends to the supporting evidence required for detailed review.

The first practical step is to identify what already exists and assign the missing information to the appropriate people. Disclosure can then proceed in an organised way, with control over content, updates and confidentiality.

Frequently asked questions

What documents are needed to start assessing the sale of a business?

An initial assessment requires financial statements for recent years, an up-to-date income statement and balance sheet, details of financial debt and cash, key sales information and an organisation chart. These materials help explain the company’s performance, structure and characteristics and identify where further investigation is needed.

Can you start preparing a business for sale without having all the documents?

Yes. Preparation can begin with the available materials, working with an adviser to identify missing information and assign responsibility for producing it. Gaps should be made explicit, as they may limit the reliability of the initial valuation or require further work before the business is presented to buyers.

How many years of financial statements are needed to sell a business?

The last three financial years provide a useful starting point, alongside up-to-date financial information. The period reviewed may vary according to the company’s history, seasonality and significant changes in its operations. Three years should therefore be treated as a practical reference rather than a rule for every transaction.

Who prepares the documents for a business sale?

The finance team and accountant prepare the accounting information, while managers and advisers collect commercial, contractual, technical and employee information within their areas of responsibility. The owner clarifies the objectives and scope of the sale. The M&A adviser coordinates preparation and organises disclosure to potential buyers.

When should customer names and full contracts be shared with a potential business buyer?

Customer names and complete contracts should be shared when they are needed to assess the transaction, with appropriate confidentiality agreements and access arrangements. Aggregated figures and summaries of key relationships may be sufficient initially. If the buyer is a competitor, commercially sensitive information requires particular care.
