How to Know Whether Your Business Can Afford to Grow
Can your business afford to grow? Your business is growing, sales are increasing, and new opportunities are appearing.
That sounds like good news — and it usually is.
But growth creates a financial question that many business owners overlook:
Can your business actually afford to grow?
Taking on a new employee, buying equipment, increasing stock, moving into larger premises or accepting a much larger customer order can all require significant cash before the additional revenue arrives.
A business can therefore be growing successfully while simultaneously experiencing increasing financial pressure.
The important question isn’t simply “How much more can we sell?”
It’s:
“Can our cash flow, profit margins and working capital support the growth?”
Growth is not the same as financial health
One of the easiest mistakes to make is to use revenue as the main measure of business success.
If turnover is increasing, it can feel as though the business must be getting healthier.
But revenue only tells you how much the business is selling. It doesn’t tell you how much profit you’re making, when customers will pay, how much cash is tied up in the business or whether you have enough working capital to cover your commitments.
This distinction becomes particularly important during periods of rapid growth.
The British Business Bank notes that growth can actually create cash-flow problems because additional sales may require more working capital, stock and credit given to customers before the associated cash is received.
So before deciding to grow, don’t just ask:
“Will this generate more revenue?”
Ask:
“What will this growth require financially before it starts paying for itself?”
1. Start with cash flow
The first question should be simple:
What will happen to our cash position if we grow?
Imagine your business wins a new £100,000 contract.
That sounds excellent.
But perhaps you need to:
- buy £20,000 of materials
- employ additional staff
- pay suppliers before receiving payment from the customer
- increase stock levels
- spend more on transport or production
- wait 30, 60 or even 90 days for the customer to pay
The £100,000 sale may improve your revenue immediately.
The cash might arrive much later.
This is why cash flow forecasting is so important.
A cash flow forecast helps you estimate when money is expected to enter and leave the business, allowing you to identify potential shortfalls before they become urgent problems.
Before making a significant investment or accepting a major new contract, look at the expected cash position over the coming months — not just the expected revenue.
2. Understand your real profit margin
More sales do not automatically mean more profit.
Suppose your business generates an additional £50,000 of revenue.
That sounds positive.
But what does it cost to generate that £50,000?
You may have additional:
- wages
- materials
- subcontractor costs
- delivery costs
- software
- marketing
- insurance
- premises costs
- financing costs
If your gross margin or net margin falls as you grow, you could end up working harder without creating the financial improvement you expected.
That’s why revenue growth should always be considered alongside profitability.
Ask:
How much additional profit will this growth actually generate?
And even more importantly:
How much cash will it consume before that profit reaches the bank account?
3. Check your working capital
Working capital is one of the areas business owners often underestimate when planning growth.
In simple terms, working capital represents the resources available to fund the business’s day-to-day operations.
Money can become tied up in:
- unpaid customer invoices
- stock
- work in progress
- supplier timing
- VAT and tax obligations
- other short-term commitments
The faster a business grows, the more working capital it may need.
The British Business Bank specifically highlights that growing businesses can need additional working capital because costs are incurred before customers pay for the resulting products or services.
This creates an important distinction:
Profit tells you whether the business is generating economic value.
Cash flow tells you whether the business has enough cash available when it needs to pay its bills.
You need both.
4. Look at customer payment times
One of the most overlooked growth risks is getting paid too slowly.
Imagine that your sales increase by 30%, but your customers consistently take 60 days to pay.
Your revenue may look excellent.
Your bank account may tell a very different story.
The longer your cash conversion cycle, the more working capital your business may need to finance the period between paying your own costs and receiving customer payments.
Before expanding, review:
Debtor days
How long does it typically take customers to pay?
Payment terms
Are you giving customers longer credit than your business can comfortably support?
Outstanding invoices
How much cash is currently sitting outside the business?
Customer concentration
What would happen if one major customer paid late?
Growth is much safer when your cash collection process grows with your sales.
5. Don’t forget the costs that arrive after the decision
A common mistake is to calculate the initial cost of growth but ignore the ongoing commitment.
For example, hiring an employee doesn’t simply mean paying their salary.
You may also have additional:
- employer costs
- software and equipment
- training
- office space
- insurance
- recruitment costs
- management time
The same principle applies to equipment.
The purchase price is only part of the decision.
You may also need to consider:
- maintenance
- insurance
- financing
- energy
- storage
- depreciation
- replacement costs
The question therefore shouldn’t be:
“Can we afford to make this purchase?”
It should be:
“Can we comfortably afford the full financial commitment?”
6. Build a cash-flow forecast before you commit
A simple forecast can transform a growth decision.
Before committing to a major expense, model the expected impact on your cash position.
At a minimum, look at:
Current position
How much cash does the business have today?
Additional investment
How much will the growth decision cost?
Additional monthly costs
What recurring costs will it create?
Expected additional revenue
When will the additional sales actually start?
Customer payment timing
When will the money realistically reach your bank account?
Tax and other obligations
What additional VAT, PAYE, corporation tax or other liabilities could arise?
Cash buffer
How much cash will remain after the investment?
The British Business Bank recommends using cash-flow forecasts to anticipate potential cash shortages and plan ahead rather than discovering the problem after it has occurred.
7. Test the downside scenario
This is where good financial planning becomes much more useful.
Don’t build your decision around the assumption that everything will go according to plan.
Ask:
What happens if sales are 20% lower than expected?
What if customers pay 30 days later?
What if costs increase?
What if the new employee takes longer to become productive?
What if the new contract is delayed?
What if you have an unexpected tax or equipment bill?
You don’t need to predict the future perfectly.
You need to understand how much financial room your business has if things don’t go according to plan.
A business with a strong forecast and reasonable cash buffer has more flexibility to respond to unexpected events.
8. Ask whether growth is actually the right decision
This is perhaps the most important question.
Not every opportunity should be accepted.
A new contract may increase revenue but produce poor margins.
A new employee may increase capacity but create pressure on cash flow.
More stock may allow you to fulfil more orders but tie up capital.
A larger premises may support future growth but create a fixed cost that becomes difficult to manage if sales slow.
Sometimes the financially stronger decision is to grow more slowly.
That isn’t failure.
It is disciplined growth.
Successful growth should improve the underlying strength of the business rather than simply make the numbers at the top of the profit and loss account look bigger.
A simple growth affordability checklist
Before making a significant investment, ask yourself these seven questions:
1. Will this decision increase revenue?
If yes, by how much and when?
2. Will it increase profit?
Don’t confuse additional sales with additional profit.
3. How much cash will it require upfront?
Include costs that may occur before additional revenue arrives.
4. How much additional working capital will we need?
Consider stock, debtors and payment timing.
5. When will customers actually pay us?
Revenue is not the same as cash received.
6. What happens if the plan underperforms?
Model a less optimistic scenario.
7. How much cash will remain after the decision?
Don’t use every available pound simply because it is currently in the bank.
If you cannot answer these questions confidently, you may not yet have enough information to make the decision.
Growth should make your business stronger
Growth is one of the most exciting stages of running a business.
But bigger isn’t automatically better.
The strongest businesses don’t just focus on increasing sales. They understand how growth affects profitability, cash flow, working capital and financial resilience.
Before committing to the next employee, the next piece of equipment, the next large order or the next expansion opportunity, take a step back and look at the numbers.
Because the real question isn’t:
“Can we grow?”
It’s:
“Can we grow without putting unnecessary pressure on the business?”
At Langner & Co. Financial Services, we help UK small and growing businesses understand their numbers, improve financial visibility and make better-informed decisions.
Clear numbers. Brighter decisions.
Thinking about your next stage of growth?
Before committing to additional costs, make sure your cash flow, profitability and working capital can support the decision.
