How to read your management accounts: a plain-English guide

Management accounts are the internal view of how a business is really doing month by month. They are not filed anywhere and do not have a legal format. The point is to see what statutory year-end accounts cannot show in time: whether this month was better or worse than last, where margin is being made or lost, and what cash looks like for the next few weeks.

A typical pack has four parts: a profit and loss statement (P&L), a balance sheet, a cash summary, and a short set of key performance indicators (KPIs).

The profit and loss (P&L)

The P&L shows how the business performed over a period — usually a month, a quarter or year-to-date. It runs from revenue at the top to profit at the bottom.

• Revenue (or turnover). What you invoiced customers in the period, net of VAT.
• Cost of sales. The costs that scale directly with revenue: materials, direct labour on a project, cloud-hosting for a SaaS customer.
• Gross profit and gross margin. Revenue minus cost of sales, and the same figure as a percentage. Gross margin is the single most useful number for pricing and product mix.
• Overheads. Fixed costs that do not scale directly with sales: rent, insurance, software, salaries not booked to cost of sales.
• Operating profit. Gross profit minus overheads.
• Net profit. Operating profit after interest and tax.

A well-presented P&L shows at least three columns: the current period, the prior period (or budget), and year-to-date.

Illustrative P&L extract

Revenue is up by 11% but gross margin is down 5 points, so operating profit is flat. The number that needs attention is not profit — it is cost of sales.

The balance sheet

The balance sheet is a snapshot at a specific date, usually the last day of the month. It shows what the business owns (assets), what it owes (liabilities), and the difference (equity).

• Fixed assets. Things the business will use for more than a year.
• Current assets. Cash, trade debtors, stock.
• Current liabilities. Suppliers, VAT, PAYE, short-term loans.
• Long-term liabilities. Loans and other debts due after 12 months.
• Equity. Share capital plus retained profits.

Two quick checks on a balance sheet: current ratio (current assets ÷ current liabilities) gives a rough read on whether the business can meet its next 12 months of bills, and net assets (total assets minus total liabilities) should match equity.

The cash view

Profit is not cash. A business can be profitable on paper while running out of cash, usually because customers pay slowly, stock is piling up, or VAT and PAYE have not been set aside.

1. Opening cash. Bank balance at the start of the period.
2. Cash in and cash out. Receipts from customers, payments to suppliers, payroll, HMRC payments.
3. Closing cash and runway. Bank balance at the period end, plus how many months of operating costs that balance would cover at the current burn rate.

A sister article in this series covers how to calculate cash runway.

The KPIs that usually matter

• Gross margin % — pricing and product mix.
• Debtor days — on average, how long customers take to pay.
• Current ratio — short-term financial health.
• Runway (months) — how long cash lasts at current burn.
• Customer concentration — the share of revenue from the top one or three customers.

How to use management accounts

The point of a monthly pack is to prompt decisions, not to be read like a novel. A short routine works for most businesses: look at revenue and gross margin first, then at the KPIs page, then at cash and anomalies.
