Selling a business is a major milestone—one that requires careful planning, preparation, and execution. Many business owners assume that if they’ve built a successful company, buyers will naturally line up, and the sale will be smooth. However, numerous factors can create roadblocks, reduce the value of the deal, or even cause it to fall through entirely.

If you want to secure the best possible exit and avoid unnecessary stress, here are the most common issues that can arise when selling a business—and how to prevent them.

1) Lack of advance planning

If you have desired or required financial goals, such as a target net amount after taxes for your dream retirement, it’s essential not to leave it to chance. Failing to plan ahead can result in a less favourable sale price and unnecessary complications during the process.

We also often hear from clients who come to us after being approached by a potential buyer or broker. Unfortunately, this leaves us playing catch-up with planning the desired exit value, advising on tax implications, and collaborating with their financial advisor to ensure the sale meets their goals.

2) Unclear financial records

Messy financial records can be a dealbreaker. This doesn’t just refer to a shoebox of receipts—it’s about ensuring your monthly numbers are consistent and accurate. For instance, missing details like stock or work-in-progress movements, or misplacing annual expenses in the wrong months, can raise red flags. Buyers want to see clear, organised, and accurate financials that reflect the true health of your business on a monthly basis.

3) Overdependence on the owner

If your business can’t run without you, it can be a major deterrent for buyers. To make your business more attractive, it’s crucial to make it less dependent on you (delegate key tasks and build a self-sustaining team) before you sell. This reduces the perceived risk for the buyer and increases the business’s value.

Malcolm (Founder of A4G) actually wrote a book called Making Your Business Less Dependent On You, to help with this. You can buy on Amazon Kindle here, or download for free here.

4) Over-reliance on key customers 

Relying too heavily on a small number of customers is risky for potential buyers. If most of your revenue comes from just one or two customers, it could make your business appear vulnerable. Diversifying your customer base ahead of time can make the business more attractive and reduce perceived risks.

5) Market or industry decline

If the market or industry you operate in is facing a downturn, it can affect the value of your business. Timing the sale is critical selling when your business is thriving, or the market is in an upswing can make a significant difference in the deal’s value.

6) Overvaluing the business

It’s understandable to feel that your hard work has created something worth a fortune, but overpricing your business can scare away potential buyers. A professional valuation can help you set a realistic price that reflects the true value of your business and keeps negotiations on track.

7) Legal issues

Unresolved legal issues—such as pending lawsuits, unclear ownership structures, or poorly drafted contracts—can cause serious complications during the sale process. Ensure that any legal loose ends are addressed and resolved before you begin negotiations.

8) Inadequate due diligence preparation

Due diligence is a crucial part of the sale process. Buyers will conduct a deep dive into your business, and if key documents like tax filings, supplier agreements, or contracts are missing, it can cause delays or even derail the sale. Preparing your documentation early and ensuring everything is in order can smooth the due diligence process and reduce the risk of the deal falling through.

9) Poorly documented roles and processes

Buyers want confidence that the business will continue to operate smoothly without the current owner. If your team structure, job responsibilities, or key processes are undocumented or unclear, it raises concerns about continuity and risk.

Take the time to clearly document who does what, how key tasks are carried out, and where responsibilities sit. A business that runs like a well-oiled machine—without relying on any one person—is far more attractive (and valuable) to a potential buyer.

10) Disorganised systems and data

A chaotic internal system can be a big red flag. If your customer, supplier, HR, or operational data is spread across emails, spreadsheets, and disconnected platforms, it makes the business feel disjointed and harder to take over.

Buyers look for businesses with clean, centralised systems—ideally a solid CRM, finance tools, and operational dashboards that provide visibility and control. Getting your systems in order early makes your business feel more professional and easier to scale or integrate post-sale.

The A4G Way – How A4G can help to maximise the value of your business

Selling a business isn’t just about finding a buyer—it’s about getting the right deal under the best possible terms. Unfortunately, many business owners overlook the importance of preparation until it’s too late. Whether it’s failing to plan for tax implications, not addressing legal issues in advance, or leaving key financial documents unorganised, these missteps can cause significant headaches down the line.

At A4G, we work with you before the sale process begins to help you avoid these common issues and ensure a smooth transition. By addressing problems like lack of advance planning, we can help you create a strategy that aligns with your long-term goals—whether that’s a specific retirement target or a smooth exit to focus on new ventures.

Here’s how we can support you through the sale process:

Firstly, choosing the right broker is critical. Think of it as choosing the right dance partner—you need someone who knows the steps and won’t get in your way. Unfortunately, as accountants, we’ve seen our fair share of horror stories: deals with only one potential buyer (which kills any chance of negotiation), poor terms that leave sellers financially exposed, and deferred payments that never materialise.

What’s even worse? Some brokers only care about closing the deal. Once the ink dries, they’re done. At A4G, we take a different approach.

We collaborate with a select group of trusted brokers who have proven success in closing deals. Our priority is ensuring the right fit for our clients—whether it’s negotiating the broker’s role, avoiding duplicate work, or ensuring that our financial reporting is in the right format for buyers before your business even goes to market. By working together, we help maximise the value of the deal and ensure everything is in order before you start negotiating.

Case study: What happens when you miss the detail

In one recent deal, a broker and solicitor told us that the buyer’s purchase structure wasn’t our concern as we were acting for the seller. However, the buyer was purchasing shares as an individual and using multiple lending facilities to fund the deal. This created a situation where the buyer’s loan repayments would be subject to personal tax, effectively doubling the real cost of the deal for the buyer.

Had we been involved earlier; we could have identified this potential issue upfront. By flagging it during the initial stages of negotiation, we could have structured the deal differently—perhaps suggesting a different financing structure or negotiating more favourable terms for the buyer. This would have reduced the risk of deferred payments, ensuring the deal closed smoothly.

The key lesson here? Early involvement and proactive planning can prevent potential pitfalls and ensure that you don’t lose out on money due to poorly structured deals.
