Frequently Asked Questions
What is revenue?
Revenue is the total income from sales before any deductions. It equals the number of units sold multiplied by the price per unit. Revenue is the top line of your profit and loss statement.
What is the difference between revenue and profit?
Revenue is total sales income. Gross profit is revenue minus cost of goods sold. Net profit is gross profit minus all operating expenses, interest and tax. A business can have high revenue but low profit if costs are high.
When must I register for VAT?
You must register for VAT when your taxable turnover exceeds £90,000 in any 12-month period (2025/26 threshold). You can voluntarily register below this threshold, which may benefit B2B businesses.
How do I forecast revenue?
Multiply expected unit sales by average price. Use conservative, moderate and optimistic scenarios. Factor in seasonality, market trends and marketing spend. Review actual performance against forecasts monthly.
What is a good profit margin?
Profit margins vary by industry. Retail typically achieves 5-10% net margin, professional services 15-25%, software/SaaS 20-40%. Compare your margins to industry benchmarks to assess performance.
