⚠️ Mistakes When Selling a Business: The One That Costs Owners the Most

If you are thinking about selling your company, there is one mistake that costs business owners more than anything else.
It is not choosing the wrong buyer. It is not overpricing the business. It is not even waiting for the right time.
The biggest mistake is this: Failing to prepare properly before going to market.
And it is one of the most common mistakes when selling a business
Why Preparation Is Everything
When buyers look at a business, they are not just reviewing your turnover and profit. They are looking at how easy it is to take over, how well documented the business is, and how much risk they would inherit.
If your business is not presented clearly, if the numbers are not organised, or if everything relies on you, buyers will do one of two things:
Walk away
Lower their offer
That is why lack of preparation leads to delayed deals, discounted valuations and disappointed sellers.
Common Signs of Poor Preparation
At Novus, we see a lot of deals fall apart because the seller rushed to market before getting things in order.
Here are a few red flags that stop deals in their tracks:
No documented systems or handover plan
Financials that are hard to understand or poorly presented
Confusion around owner roles and responsibilities
Unrealistic price expectations
Unclear customer or supplier contracts
You might still get interest, but you will not get the best buyers or the best price.
What Preparation Really Looks Like
Preparing your business for sale means treating the exit like a project, not an afterthought.
Here is what you should be doing at least six to eighteen months before selling:
Get your financials in order and remove personal expenses
Reduce dependency on yourself as the owner
Systemise and document key operations
Organise contracts, leases and legal documents
Get a realistic valuation from someone who knows the market
Plan your narrative — why someone should buy your business now
The earlier you do this, the more power you have when buyers come to the table.
What Smart Sellers Do Differently
Successful exits are not just about how much the buyer offers — they are about how much control you keep throughout the process.
The smartest sellers:
Start planning long before they want to sell
Get advice from a broker, accountant or lawyer early
Think like a buyer
Invest time upfront to protect the final value
These sellers do not just walk away with a deal. They walk away with clarity, confidence and maximum return.
