If you’ve ever left a meeting with an accountant, opened a letter from HMRC or looked at your accounts and thought, “I have no idea what that means,” you’re not alone.
One of the biggest frustrations is that accounting can feel like its own language. Terms such as turnover, profit, payment on account and cash flow are used regularly, but you may never have been shown what they mean in practical terms. I believe understanding your finances should not require an accounting qualification. So, I’ve put together this guide to some of the questions I’m most often asked by business owners like you.
Is Turnover the Same as Profit?
This is probably the most common misconception we come across.
Turnover is the total amount your business earns before any costs are deducted.
Profit is what remains after those costs have been paid.
For example, if your business invoices £150,000 during the year, your turnover is £150,000. If your expenses total £100,000, your profit is £50,000.
You can have strong turnover and still struggle financially if costs are not managed properly.
That’s why I always tell my clients that profit is often a more useful measure of financial performance than turnover alone.
What Is a Profit and Loss Account?
A Profit and Loss Account, often shortened to P&L, shows how your business has performed over a period.
It summarises:
- income received
- business expenses
- gross profit
- net profit
It is usually one of the first reports I review with you when discussing your financial condition. Think of it as your financial scorecard that shows whether you’re making money and where that money is being spent.
Why I Always Bring Up Cash Flow
Cash flow is one of the most misunderstood areas of business finance in my experience. It simply refers to the movement of money in and out of your business.
It may surprise you to learn that you can be profitable and still experience cash flow problems.
For example, if your customers take several months to pay invoices, you may struggle to pay suppliers, wages or tax bills despite making a profit on paper.
This is why I encourage every client to monitor their cash flow just as closely as they monitor their profit.
What Are Allowable Expenses?
Allowable expenses are business costs that HMRC allows you to deduct before calculating your tax bill.
Common examples include:
- business mileage
- accountancy fees
- office costs
- professional subscriptions
- business insurance
- the business proportion of phone and internet costs
Claiming every legitimate allowable expense helps ensure you’re not paying more tax than necessary.
I always review this carefully with clients, so nothing is missed.
What Is a Payment on Account?
This is one of the questions that often catches new sole traders and small business owners by surprise.
A Payment on Account is essentially HMRC asking for part of next year’s tax bill in advance. Once your tax liability reaches a certain level, HMRC generally requires two advance payments each year. I always explain this in detail to clients so there are no surprises.
You might assume you are being taxed twice when you first encounter this system. HMRC is simply collecting part of the following year’s liability early.
When Do I Need to Register for VAT?
Currently, businesses must register for VAT when taxable turnover exceeds £90,000 within a rolling 12-month period.
One important point is that HMRC does not look at your accounting year. It uses a rolling 12-month calculation. That means I recommend reviewing your turnover regularly, rather than waiting until year-end.
VAT registration affects your pricing, cash flow and profitability, so it is worth seeking advice before you reach the threshold.
What Is Making Tax Digital?
Making Tax Digital (MTD) is HMRC’s programme to move tax reporting online.
If you are a sole trader or landlord, MTD for Income Tax begins from April 2026.
The changes require businesses to:
- keep digital records
- use compatible software
- submit quarterly updates
- complete an annual declaration
The aim is to help you reduce errors and encourage more regular record-keeping.
What Is a Tax Code?
A tax code tells your employer how much income tax should be deducted from your wages through PAYE. Most people rarely look at their tax code. However, incorrect tax codes are more common than you might realise. An incorrect tax code can result in paying too much tax or creating unexpected underpayment.
If you receive a tax code notice from HMRC and are unsure whether it is correct, let’s review it together.
What Is Bookkeeping?
Bookkeeping is the day-to-day recording of financial transactions within a business.
This includes:
- recording sales
- recording expenses
- reconciling bank accounts
- preserving accurate records
Good bookkeeping is the foundation of good accounting for your business. Without accurate records, it becomes much harder to understand profitability, manage cash flow and meet your tax obligations.
We can help put the right systems in place if you find this challenging.
What Is the Difference Between Your Debtors and Creditors?
These terms frequently cause confusion for business owners.
Debtors are your customers who owe your business money.
Creditors are suppliers or businesses that you owe money to.
Understanding both helps you get a clearer picture of your actual financial position. Your business may appear healthy on paper but still experience cash-flow pressure if large amounts remain unpaid by your debtors.
One Final Thought
There is no such thing as a silly accounting question, especially when it comes to your business. You are an expert in your own industry, not in tax legislation or financial reporting.
In my experience, our clients who operate most comfortably financially are usually those willing to ask questions early rather than waiting until a problem develops. I believe understanding your finances should be straightforward.
A short conversation today is often far easier than dealing with an avoidable problem later.
