Why profitable businesses go bust
Here's a fact that surprises most people: a business can be profitable and still run out of money. Profit and cash are not the same thing.
If Sam sells 10,000 worth of clothes in December but customers don't pay until February, the Profit and Loss statement shows a great December. But Sam's bank account doesn't have the money to pay for more stock in January. That's a cash flow problem, and it kills more businesses than lack of profit.
Financial statements exist to show you three different angles on the same business. Together, they give you the full picture.
The three statements
1. Profit and Loss (P&L) -- "Are we making money?"
The P&L (also called the income statement) shows your revenue minus expenses over a period -- usually a month, quarter, or year. The bottom line is your profit or loss.
Structure:
| Line | What it is |
|---|---|
| Revenue | Total income from sales |
| - Cost of goods sold | Direct costs of what you sold (stock, materials) |
| = Gross profit | Revenue minus direct costs |
| - Operating expenses | Rent, salaries, marketing, utilities, insurance |
| = Operating profit | Profit from core business activities |
| - Interest and tax | Loan interest, Corporation Tax |
| = Net profit | The final profit after everything |
The P&L tells you whether your pricing works, whether your costs are under control, and whether the business is fundamentally viable. But it doesn't tell you whether you actually have money in the bank.
Jargon Buster: Gross profit vs net profit Gross profit is revenue minus the direct cost of what you sold. It tells you if your pricing covers your product costs. Net profit is what's left after ALL expenses. It tells you if the business is actually making money overall.
2. Balance Sheet -- "What do we own and owe?"
The Balance Sheet is a snapshot of your business at a single point in time. It shows three things:
Assets -- what the business owns:
- Cash in the bank
- Money owed by customers (trade debtors / accounts receivable)
- Stock/inventory
- Equipment, vehicles, property
- Prepaid expenses (e.g., insurance paid for the year ahead)
Liabilities -- what the business owes:
- Money owed to suppliers (trade creditors / accounts payable)
- Tax owed to HMRC
- Loans
- VAT collected but not yet paid to HMRC
Equity -- the owner's stake:
- Share capital (what was invested)
- Retained profits (profits kept in the business over time)
The fundamental equation: Assets = Liabilities + Equity. Always. If it doesn't balance, something is wrong.
The Balance Sheet answers: "If we stopped trading today, what would be left after paying everyone we owe?"
3. Cash Flow Statement -- "Where did the money go?"
The Cash Flow Statement tracks actual money moving in and out of the bank. It's split into three sections:
Operating activities -- cash from day-to-day trading:
- Cash received from customers
- Cash paid to suppliers
- Cash paid in wages, rent, utilities
Investing activities -- cash spent on long-term items:
- Buying equipment or vehicles
- Selling assets
Financing activities -- cash from loans and investments:
- Taking out a loan
- Repaying a loan
- Dividends paid to shareholders
The Cash Flow Statement explains why your bank balance changed. If the P&L says you made 25,000 profit but your bank only grew by 8,000, the Cash Flow Statement tells you where the other 17,000 went (stock, equipment purchases, loan repayments, tax payments).
How they connect
The three statements are linked:
- Net profit from the P&L feeds into retained earnings on the Balance Sheet
- Cash from operations on the Cash Flow Statement adjusts the P&L profit for non-cash items and timing differences
- Cash and bank balances on the Balance Sheet must match the closing balance on the Cash Flow Statement
Think of it this way: the P&L tells you the score, the Balance Sheet tells you the league table, and the Cash Flow Statement tells you how the game was actually played.
Filing requirements
Limited companies must file accounts with both Companies House and HMRC:
| Where | What | Deadline |
|---|---|---|
| Companies House | Annual accounts (Balance Sheet + notes, P&L optional for micro/small companies) | 9 months after year end |
| HMRC | Full accounts with Corporation Tax return (CT600) | 12 months after year end |
Micro-entity (turnover under 632,000, Balance Sheet under 316,000, under 10 employees): Can file abbreviated accounts with Companies House -- just the Balance Sheet and limited notes. No P&L required publicly.
Small company (turnover under 10.2 million): Can file abridged accounts.
Sole traders don't file formal accounts. Your Self Assessment includes a summary of income and expenses, but you don't need to prepare a formal P&L or Balance Sheet for HMRC. You should still create them for your own understanding.
Real Scenario: Sam's first year as a limited company
Sam's Vintage Ltd has completed its first financial year. Here are the three statements:
Sam's P&L (Year 1)
| Line | Amount |
|---|---|
| Revenue (Unbought sales) | 120,000 |
| Cost of goods sold (stock) | -42,000 |
| Gross profit | 78,000 |
| Wages (Sam + Alex) | -27,570 |
| Employer NI | -3,223 |
| Pension contributions | -795 |
| Unbought fees | -8,400 |
| Shipping | -6,200 |
| Rent (storage unit) | -3,600 |
| Insurance | -950 |
| Accountant | -1,200 |
| Software and tools | -480 |
| Marketing | -1,800 |
| Other expenses | -720 |
| Operating profit | 23,062 |
| Corporation Tax (19%) | -4,382 |
| Net profit | 18,680 |
Sam's Balance Sheet (Year End)
| Assets | Liabilities | ||
|---|---|---|---|
| Bank balance | 12,400 | Trade creditors (suppliers owed) | 3,200 |
| Trade debtors (money owed to Sam) | 4,800 | VAT owed to HMRC | 4,100 |
| Stock (unsold inventory) | 8,500 | Corporation Tax owed | 4,382 |
| Equipment | 2,200 | Total liabilities | 11,682 |
| Total assets | 27,900 | ||
| Equity | |||
| Share capital | 1 | ||
| Retained profit | 16,217 | ||
| Total equity | 16,218 | ||
| Liabilities + Equity | 27,900 |
The cash flow puzzle
Sam made 18,680 net profit. But the bank only has 12,400 (and Sam started with 2,000). So cash grew by 10,400 -- not 18,680.
Where did the difference go?
- 8,500 is tied up in unsold stock (bought but not yet sold)
- 4,800 is owed by customers who haven't paid yet (trade debtors)
- Offset by 11,682 that Sam owes to others (liabilities)
The lesson: Profit is an accounting concept. Cash is what pays the bills. Sam's business is profitable but a significant portion of that profit is locked in stock and unpaid invoices.
Real Scenario: Steve reads his numbers
Steve hasn't incorporated, but he still generates a P&L from his accounting software to understand his business:
| Line | Amount |
|---|---|
| Revenue | 78,000 |
| Materials | -8,400 |
| Gross profit | 69,600 |
| Jordan's salary + costs | -28,363 |
| Vehicle costs | -5,400 |
| Tools and equipment | -1,800 |
| Insurance | -960 |
| Waste disposal | -1,440 |
| Phone | -360 |
| Accountant | -500 |
| Net profit | 30,777 |
Steve's gross margin is 89% (mostly labour, few material costs -- typical for services). But after Jordan's salary, the biggest expense, net profit drops to 39%.
Steve's key insight: each additional gardener costs roughly 28,000 in total but can generate 40,000--50,000 in additional revenue. The maths works, but only if Steve can fill their schedule.
Cost Table: Filing deadlines and penalties
| Filing | Deadline | Late penalty |
|---|---|---|
| Companies House annual accounts | 9 months after year end | 150 (up to 1 month), 375 (1--3 months), 750 (3--6 months), 1,500 (6+ months) |
| HMRC Corporation Tax return | 12 months after year end | 100 (1 day), 200 (3 months), 10% of tax (6 months), 20% of tax (12 months) |
| Corporation Tax payment | 9 months and 1 day after year end | Interest accrues from due date |
