How to know what’s actually holding back your business growth

When business growth slows, the natural reaction is to start looking for things to do. Spend more on marketing, hire another salesperson, rebuild the website, launch a new service or try another channel.

But more activity is not necessarily what the business needs. Before deciding what to do next, you need to identify the biggest constraint currently limiting growth. Until you understand the problem, you are effectively guessing at the solution.

Why is diagnosing the problem so important?

Most established SMEs have plenty of things they could improve. The challenge is working out which one actually matters most.

Office for National Statistics data published in May 2026 found that 34% of trading businesses said economic uncertainty was affecting turnover. Among businesses with 10 or more employees, labour costs were the most commonly reported challenge affecting turnover. (ONS, 2026)

Those pressures are real, but every business experiences them differently. Your growth might be constrained by demand, your positioning, poor conversion, customer retention, operational capacity or something else entirely.

That is why I believe growth should start with diagnosis rather than tactics. Find the problem first, then decide what to do about it.

What could be holding your business back?

Strip it back and there are several points across a business where growth can become constrained:

• Market demand: there are not enough potential customers for what you sell.
• Customer understanding: you are struggling to identify or reach your best-fit customers.
• Positioning: customers do not clearly understand why they should choose you.
• Awareness: your proposition works, but not enough of the right people know you exist.
• Conversion: you generate interest and enquiries, but too few become customers.
• Retention: you win customers but lose them too quickly or fail to develop their value.
• Capacity: demand exists, but your people, processes or systems cannot handle more.
• Commercial model: pricing, margins or costs prevent revenue from becoming profitable growth.
• Cash flow: the underlying business works, but there is not enough cash available to fund growth.

The last point is a good example of why growth cannot be treated purely as a marketing problem. UK Government research estimated that businesses are owed around £26 billion in late payments at any given time, with affected businesses owed an average of approximately £17,000. (UK Government, 2026)

A company can therefore have demand, customers and revenue while still being unable to grow because cash is tied up elsewhere.

How do you identify your biggest growth constraint?

Start by mapping how growth actually happens in your business. You need a viable market, enough of the right people to discover you, a compelling reason for them to buy and an effective way of converting that demand into customers. You then need to retain and serve those customers profitably.

Look across that journey and ask: where is the biggest drop-off?

Imagine a B2B business generating 50 enquiries every month but converting only 5% into customers. The obvious reaction might be to increase marketing activity and generate 75 enquiries instead.

But lead volume may not be the problem. The business could be attracting the wrong prospects, communicating its value poorly or losing good opportunities during the sales process. Increasing marketing spend would simply push more leads through a system that is already underperforming.

That is why the numbers are useful, but they are only the start of the diagnosis.

Are you solving the problem or the symptom?

Statements such as “we need more leads”, “we need a new website” or “we need to post more on social media” often sound like problems. Usually, they are proposed solutions.

Take “we need more leads”. Why? Perhaps revenue is below target. But why is revenue below target? Lead volume could be down, conversion could have fallen, existing customers could be leaving or average customer value could have decreased.

Keep asking why until you reach something you can evidence. If website conversion is poor, understand why. If customers are leaving, speak to them. If sales conversion has fallen, look at where deals are being lost and what prospects are telling you.

Good diagnosis combines performance data with what customers, prospects and employees are actually saying.

How do you decide what to prioritise?

A proper diagnosis will probably identify more than one problem. That does not mean you should try to fix everything at once.

For an SME with limited people, time and budget, prioritisation matters. I would ask one question:

If we could materially improve one thing over the next 90 days, which would have the greatest impact on our ability to grow?

That is the constraint to focus on first.

It could be increasing awareness among a particular customer group. It could be improving sales conversion. It could be reducing churn, fixing a capacity issue or improving margins.

Best fit matters more than best practice. The right priority is the one that addresses the specific problem your business is facing, not the tactic everybody else appears to be using.

How do you turn the diagnosis into a growth plan?

Once you know what is holding the business back, the growth plan becomes much easier to build. I use a simple three-stage approach:

1. Diagnose the problem: identify the constraint having the greatest commercial impact and understand what is causing it.
2. Set the guiding policy: decide how the business is going to overcome that constraint and where resources should be focused.
3. Build the coherent set of actions: translate the strategy into a manageable number of actions, owners, measures and deadlines.

The important part is the sequence. Jumping straight to the plan creates activity without knowing whether you are solving the right problem. Diagnosis gives that activity a purpose.

When growth slows, the question should not immediately be “what else should we be doing?” A better question is “what is preventing us from growing right now?” Once you can answer that properly, you can stop spreading time and budget across disconnected activities and build a focused plan around the things most likely to make a commercial difference.
