There are many options when considering the best place/organisation/channel to sell a business.
Corporate Finance functions either in standalone firms or part of large accountancy firms are often a first port of call for many as they are often familiar with the firms from other dealing with them. They usually focus more on the advisory element and due diligence once a deal is in place rather than the actual process of finding a buyer and prefer deals with a buyer already in place, which is often not the most helpful for many for whom that stage is key.
Sales agents/brokers are another place to go to sell a business. These often focus on finding a Buyer via large scale direct marketing campaigns. The key here is trying to just contact as many people as possible.
The simplest option is to subscribe to a website offering to list your business. This is more of a lucky dip gamble. If an interested party is found via this approach there is still the need for a Seller to find advisers to negotiate, manage due diligence, provide financial and taxation advice. Then legal advisers are required to establish non-disclosure agreements, Heads of Terms and a Sale and Purchase Agreement. This low-cost website listing option can soon run up significant costs from a number of other advisers.
When deciding what is the best place to sell a business it is essential to first invest in a clear pathway to maximising the probability of a successful sale and optimising the business value. Putting the business itself in its best place is as important as finding who or whereis the best place to sell. This is an investment not a cost, and an experienced adviser who can help to avoid the pitfalls and own the problems is invaluable.
