The 5 Numbers Every Business Owner Should Know.
Summer’s over. We’re back at our desks. Now it’s time to get back to business.
The holidays are done. The out-of-office messages are coming down. The school runs are back. And for most business owners, September feels like a natural reset.
It’s time to stop thinking about the beach, the BBQs and the few weeks where the business could take a back seat.
Now it’s time to focus on the business again.
And one of the best places to start is with your numbers.
Because whether you’ve had a brilliant summer, a quiet few weeks or you’ve barely stopped working, you need to know where your business stands.
You don’t need to be an accountant.
But you do need to understand your numbers.
Your accountant can prepare the figures. But you should know what they’re telling you — and what you need to do next.
So, as we head into the final few months of the year, here are five numbers every business owner should know.
1. Your Cash in the Bank
Let’s start with the obvious one. How much cash do you actually have available today?
Not what you’ve invoiced. Not what you expect to be paid. Not what you think you’ve made.
What’s actually in the bank?
Cash flow can make or break a small business. You can be profitable on paper and still struggle to pay your bills if customers are slow to pay or you’ve got significant costs coming up.
That’s why understanding small business cash flow matters.
As you get back into the rhythm of business after the summer, take a proper look at:
- What’s currently in the bank
- What’s owed to you
- What’s due to be paid
- Upcoming VAT and tax liabilities
- Payroll and regular commitments
- Any significant costs or investments coming up
Don’t just look at today’s bank balance.
Look ahead.
What will your cash position look like in four, eight or twelve weeks?
That’s where cash flow forecasting becomes really useful.
2. Your Monthly Sales
Do you know exactly how much your business has sold each month this year? Do you know whether sales are going up, down or sideways?
September is a great time to look at this. The summer months can distort things. Some businesses slow down. Others get busier. Customers disappear on holiday. Projects get pushed back.
Now that we’re all getting back to normal, look at the bigger picture.
- Are sales growing?
- Are certain months consistently stronger?
- Are particular services or products performing better?
- Are you relying too heavily on one customer?
- And most importantly: Is your sales growth translating into profit?
That’s where your financial numbers start working together.
3. Your Gross Profit
This is where things get more interesting.
Gross profit = Sales minus the direct costs of delivering those sales.
It’s possible to increase sales while making less money. If you’re discounting heavily, supplier costs have increased or your pricing hasn’t kept pace with inflation, your margins can quickly disappear.
Your gross profit margin tells you whether the work you’re doing is actually worth doing.
Look at:
- Your most profitable products or services
- Where costs have increased
- Whether your pricing is still right
- Whether supplier costs need reviewing
- Whether some customers are more profitable than others
More sales isn’t always the answer. Better sales can be.
4. Your Net Profit
Now we get to one of the numbers every business owner really wants to know.
How much money is the business actually making?
Turnover gets talked about a lot.
But turnover isn’t profit.
You could tell someone your business turned over £500,000 and it sounds impressive.
But if it cost £475,000 to generate that turnover, you’ve got a very different story.
That’s why business profit tracking matters.
Don’t wait until your year-end accounts to find out whether you’ve made money.
By then, you’re looking backwards.
Regular financial reporting helps you understand what’s happening now — while you still have time to do something about it.
5. Your Tax Position
And finally, the number nobody wants to forget: How much tax are you likely to owe?
One of the biggest mistakes business owners make is looking at the money in the bank and assuming it’s all available to spend. It isn’t.
Depending on your business and circumstances, you could have Corporation Tax, Income Tax, National Insurance, VAT, PAYE or other liabilities to plan for.
So as you get back into business mode this September, make sure you know:
- What you owe.
- When it’s due.
- And whether you’ve got the money set aside to pay it.
That’s not boring accountancy. That’s good business management.
September Is a Good Time for a Financial Reset
The summer break gives many of us a chance to step away from the business. September gives us the opportunity to step back in with a clearer head.
So before the year disappears into Christmas parties, year-end deadlines and the January tax rush, take a proper look at your business.
Ask yourself:
- Do I know my numbers?
- Do I understand my cash flow?
- Do I know where my profit is coming from?
- Do I know what tax is coming?
And perhaps most importantly: Is my accountant actually helping me understand all of this?
Because your accountant shouldn’t just tell you what happened last year. They should help you understand what’s happening now and what you should be thinking about next.
Thinking About Switching Accountant?
If September feels like a good time for a business reset, it could also be the right time to review your accountant.
If you’re constantly chasing for answers, don’t understand your accounts or only hear from your accountant when something needs filing, ask yourself a simple question: Are you getting the service your business deserves?

Frequently Asked Questions
What numbers should every business owner know?
At a minimum, you should understand your cash position, monthly sales, gross profit, net profit and upcoming tax liabilities. Reviewing these regularly helps you make better business decisions.
Why is small business cash flow so important?
Cash flow shows the money coming into and leaving your business. Even a profitable business can experience cash flow problems if customers pay late or significant bills fall due before expected income arrives.
How often should I track my business profit?
Ideally, business owners should review profitability at least monthly. Regular business profit tracking gives you an opportunity to identify falling margins, rising costs or weaker sales before they become bigger problems.
What is business financial planning?
Business financial planning means looking ahead rather than simply reviewing what has already happened. It can include budgeting, cash flow forecasting, tax planning, managing costs and planning future investment or growth.
Is September a good time to review my business finances?
Absolutely. After the summer, September provides a natural opportunity to reset, review performance and plan for the final months of the year before the busy year-end period begins.
