How Long Does It Take to Sell a Business? A Guide to the M&A Process

For many business owners, one of the first practical questions is: how long will it actually take to sell the business?

As a broad guide, we would typically tell owners to allow approximately 6–11 months for a well-run private company sale process from initial preparation through to completion. That is indicative rather than prescriptive. A straightforward transaction with a well-prepared business and a motivated buyer can move more quickly, while a complex deal, regulatory review, financing process or difficult due diligence can extend the timetable materially.

The important point is that selling a business is rarely a single event. It is a sequence of preparation, buyer engagement, negotiation, due diligence and legal documentation, with each stage affecting the next.

The first phase is preparation

Before a buyer is contacted, the business needs to be positioned properly. This is where the financial story is tested, normalised EBITDA is considered, the key investment highlights are developed, potential risks are identified and the buyer universe is mapped.

For a good-quality mid-market process, this preparation can take several weeks. It often includes building the Information Memorandum, preparing a financial databook, organising key documents for a data room and agreeing on the strategy for approaching the market.

This work can feel slower than owners expect because there is an understandable temptation to “just start talking to buyers”. In practice, however, time spent preparing well at the beginning usually saves time later. Buyers move more confidently when the information is clear, consistent and able to withstand scrutiny.

Taking the business to market

Once the materials are ready, selected buyers are approached confidentially. Depending on the business, this may include Australian and international strategic acquirers, private equity firms, family offices, search funds and other financial investors.

Interested parties will usually sign confidentiality agreements before receiving detailed information. From there, they begin assessing the business, asking initial questions and determining whether they want to progress.

This stage is not simply about finding someone willing to buy the company. A well-managed process is designed to identify the buyers for whom the business has the greatest strategic or financial value and, where possible, create competitive tension between them. That competition can be important not only for price, but also for transaction terms, certainty and the seller’s negotiating position.

Indicative offers and choosing the right buyer

After buyers have had an opportunity to assess the business, serious parties may be invited to submit indicative, non-binding offers. This is often the first point at which the range of possible outcomes becomes tangible.

Headline valuation matters, but it is only one part of the assessment. The proposed structure, funding certainty, conditions, due diligence requirements, treatment of management, any earn-out or deferred consideration, and the buyer’s ability to complete can all have a meaningful impact on the quality of an offer.

Shortlisted buyers may then meet management, visit the business or undertake further analysis. For many founders, this is also the point at which the “fit” with a buyer becomes clearer. Owners are often thinking about employees, customers, culture, brand and legacy as well as financial value.

Due diligence is usually the most intensive phase

Once a preferred buyer is selected, the transaction typically moves into detailed due diligence and legal documentation. This is often the most demanding phase for management because the buyer is now testing the assumptions that supported its offer.

Financial, tax, legal, commercial, operational, technology, cyber, employment and insurance matters may all be reviewed depending on the nature of the business. At the same time, the parties and their lawyers are negotiating the sale documentation, including purchase price mechanics, working capital, warranties, indemnities, conditions and completion arrangements.

A well-organised data room and disciplined Q&A process can make an enormous difference here. The goal is for due diligence to confirm the story already presented to the buyer, rather than introduce unexpected issues late in the process.

Why some transactions take longer

The 6–11 month timeframe should always be treated as indicative because no two transactions are identical. Timelines can extend where financial information is incomplete, contracts are poorly documented, customer or supplier concentration requires additional investigation, trading performance changes during the process, financing takes longer than expected, or the parties have difficulty agreeing on transaction structure.

Regulatory requirements can also affect timing. In Australia, the merger control regime that commenced on 1 January 2026 is mandatory and suspensory for acquisitions meeting the relevant notification requirements. Where the regime applies, the transaction cannot proceed until the necessary ACCC approval or waiver has been obtained, so this needs to be considered early in the process rather than just before signing or completion.

The best time to start is before you need to sell

Owners sometimes choose a target retirement date and then work backwards only a few months to start a sale process. That can place unnecessary pressure on both the timetable and the transaction outcome.

If there are issues to address before going to market — such as management dependence, customer concentration, financial reporting, margin improvement or a growth initiative that needs time to demonstrate results — the real preparation period may begin 12–24 months before the formal sale process.

That does not mean every owner needs to spend two years getting ready. It means that the more time available, the more ability an owner has to strengthen the business before buyers begin assessing it.

At G&G Advisory Partners, we manage private-company transactions from preparation and valuation through buyer identification, negotiation, due diligence and completion. As a general guide, we would allow approximately 6–11 months for the transaction process itself, while recognising that preparation for the best possible outcome may sensibly begin much earlier.
