The short answer
The seven numbers, and what each one tells you
You do not need a complex management accounting system or a £500-a-month dashboard. You need seven figures that you can find in fifteen minutes and interpret without needing to call your accountant. That's the real freedom—knowing where you stand financially, exactly and simply, at any moment. These figures are like the pulse rate of your business—they indicate its health instantly and allow you to respond in real-time.
- 1. Revenue (Turnover) — Everything you invoiced or sold in the period. It tells you about demand and volume, and absolutely nothing else. High revenue does not mean a healthy business. A surge in revenue might feel like a windfall, but without context, it's just a number on a page.
- 2. Gross margin — Revenue minus the direct cost of delivering it, expressed as a percentage. It tells you whether the work itself is priced properly and is worth doing. If your gross margin is thin, every sale you make might be a step closer to insolvency instead of profit.
- 3. Net profit — What is left after all overheads, software, rent, and your own pay are deducted. It tells you whether the business model, rather than just the individual job, actually works. It’s the ultimate indicator of the sustainability of your business practices.
- 4. Cash in the bank — The actual cleared balance across every business account today. It tells you what you can act on right now. Cash flow can be the lifeline of your business, showing you what you can invest or pay off immediately.
- 5. Money owed to you (Debtors) — Invoices raised and unpaid, split by how overdue they are. It tells you how much of your hard work is currently acting as a free overdraft for someone else. Monitoring this carefully is crucial to converting work into tangible revenue.
- 6. Money you owe (Creditors + Tax) — Unpaid suppliers, finance payments, and above all, tax accrued. It tells you exactly which part of your bank balance is an illusion. These liabilities can significantly impact your available capital at a moment’s notice.
- 7. Runway — How many weeks the business can survive at its current burn rate if all income stopped tomorrow. It tells you how much time you are actually buying with each decision. It's a reality check and a motivator to keep finding and fixing issues.
Where each number comes from
Revenue, gross margin, and net profit come from your bookkeeping or accounting software (like Xero or FreeAgent), or from a simple spreadsheet of invoices and costs if you are just starting out. Accurate record-keeping here is vital as it forms the backbone of your financial understanding.
Cash comes directly from your banking app. Money owed to you comes from your outstanding invoice list. Money you owe comes from unpaid bills plus a realistic estimate of tax accrued so far. Runway is simple arithmetic based on the other six. Having these figures quickly accessible can prevent financial panic and prepare you to make informed decisions.
If any of these takes more than a few minutes to find, that is the first problem you need to fix — not the number itself, but the system holding it. Efficient financial systems mean you can spend more time on strategy and less time scrambling for numbers.
How often to look
Weekly: Cash, money owed to you, money you owe. These three move fast, change daily, and cause the urgent, stressful problems that keep you awake at night. A weekly check-in with these numbers can alert you to issues before they derail your operations.
Monthly: Revenue, gross margin, net profit, runway. These move slowly and reveal the structural problems in your pricing or overheads. Monthly reviews help you adjust plans, set strategies, and ensure your business remains on a stable footing.
Annually: Nothing. Annual accounts are a compliance output for HMRC and Companies House. By the time they land on your desk, the decisions they describe are ten months old. You cannot steer a ship looking at a map from last year. Real-time data is the captain of today’s business environment.
Worked example: A consultant's month, in seven lines
- 1. Revenue
- £9,400
- 2. Gross margin
- 78% (£7,330)
- 3. Net profit after overheads and owner pay
- £1,150
- 4. Cash in the bank
- £14,200
- 5. Owed to her by customers
- £11,800, of which £4,300 is overdue
- 6. Owed by her, including tax accrued
- £9,600
- 7. Runway at current burn
- 9 weeks
Illustrative example. The bank balance looks comfortable at £14,200, but £9,600 of it is already committed to tax and suppliers. The genuine free cash is closer to £4,600, and nine weeks of runway is much thinner than the raw bank balance suggests. Regular checks could protect against unforeseen cash crunches.
What to do, in order
- 1
Create one single page
A physical piece of paper or a simple spreadsheet tab with seven rows. Do not build a complex dashboard yet. Keep it straightforward to ensure you're focused on the figures and not the format.
- 2
Fill it in badly, today
Estimates are fine for the first attempt. The first version exists simply to prove you can produce the numbers at all. Aim for improvement over precision—it’s better to know something now than exactly nothing.
- 3
Book the slot in your calendar
Fifteen minutes every Friday morning for the three fast numbers, and thirty minutes at the end of the month for all seven. Regularity builds confidence and familiarity, making financial checks a habit rather than a chore.
- 4
Write one sentence each month
Write down: 'The thing I am watching this month is X because Y.' That sentence is the whole point of the exercise. It sharpens your focus and turns data into actionable insights.
- 5
Only then automate
Once you know which numbers you actually use and trust, wire them up in software. Not before. Investing in automation should support existing practices, not define them.
Common mistakes
- Tracking revenue alone, which flatters a business with weak margins and hides structural failure.
- Treating the bank balance as available money when tax and supplier payments are already spoken for.
- Building an elaborate, colourful dashboard before establishing the basic habit of looking at anything.
- Comparing your figures to someone else's revenue claims on social media rather than comparing them to your own last quarter.
- Failing to update figures regularly, leading to outdated information that can't be relied upon for decision-making.
- Overlooking the importance of money owed, which can lead to severe cash flow constraints if not regularly followed up.
- Ignoring the true cost of doing business, such as unrecorded hours or unpaid taxes, which can distort your financial position.

Frequently asked questions
- What if I do not know my gross margin?
- Start with revenue minus anything you only pay because you did that specific work: subcontractors, materials, delivery, transaction fees. Divide that by the revenue. It will be approximate, but it will still be highly useful. This gives you a clearer view of your direct profitability and can highlight immediate areas for improvement.
- Is runway relevant to a one-person business?
- Especially so. For a solo business, the runway question is 'how many weeks can my household survive if invoicing stops tomorrow?' That is a far more urgent and practical number than your annual turnover. Understanding your runway helps prioritize actions that maintain financial safety.
- Do I need expensive software for this?
- No. A simple spreadsheet you actually update beats a £50-a-month software suite you never open. Software becomes worthwhile as transaction volume grows or where Making Tax Digital obligations force you to use it. Until then, keep things as simple as possible to ensure consistent habits.
- How can I improve my net profit?
- Improving net profit involves either increasing your revenue, reducing costs, or ideally both. Reevaluate your pricing strategy, negotiate better terms with suppliers, or cut unnecessary expenses. Strategic improvements here can make your business more sustainable long-term.
- What action should I take if money owed is high?
- Begin by reviewing your invoicing process and follow up on overdue payments. Consider offering incentives for early payments or adjusting payment terms. Consistent follow-up is key to converting debtors into cash flow, and it emphasizes the seriousness of your payment expectations.
