Your business can make a profit while its bank balance falls because profit measures income earned against costs incurred, while the bank balance reflects money actually received and paid.
Customers may still owe you money. You may have bought stock, repaid borrowing or withdrawn funds. Each affects cash differently from profit.
The useful question is: which transactions explain the gap, and will that gap close before your next bills become due?
Start by Comparing the Same Period
Before investigating, check that your figures cover matching dates. Last year’s accounts cannot explain a fall in cash this month without considering everything that happened afterwards.
Compare your opening and closing bank balances with the profit for that exact period. Include all business bank accounts: moving money into a business savings account reduces the current account balance without reducing the business’s total cash.
Also check whether your report shows gross profit, operating profit or profit after tax. Gross profit excludes overheads such as administration and office rent, so it gives an incomplete picture.
Customers Have Not Paid for Sales Already Recorded
Under accrual accounting, sales are recognised when earned, which can be before payment arrives.
Suppose you complete £15,000 of work in September and allow customers 30 days to pay. The income may appear in September’s accounts, while the cash arrives in October. Meanwhile, September’s wages and other bills still need paying.
Check your aged receivables report, which lists unpaid customer invoices and how overdue they are. Look for:
- Large invoices awaiting approval.
- Disputed charges.
- Customers repeatedly paying beyond agreed terms.
Send invoices promptly, confirm the correct billing contact and follow up before overdue balances become difficult to collect. For longer projects, agreed deposits or staged payments can reduce the amount you fund yourself.
Stock and Advance Payments Are Absorbing Cash
Buying stock can reduce your bank balance before its cost reduces profit. Under accrual accounting, unsold stock normally remains an asset until sold, subject to any necessary write-down.
A bulk purchase might improve the price per item but leave you short of money for payroll. Review how quickly products sell before reordering, especially where slow stock is building up.
Advance payments create another timing difference. If you pay £2,400 for annual insurance upfront, the full amount leaves the bank immediately. Assuming even coverage, the accounts would normally recognise £200 of expense each month.
Growing businesses often experience both pressures together: they buy more stock and pay operating costs before collecting the related sales income.
Equipment Purchases and Loan Repayments Use Cash Differently
When equipment is recorded as a fixed asset, its purchase price is not normally charged entirely against profit immediately. Instead, depreciation spreads the accounting cost over its useful life.
A £6,000 equipment purchase can therefore remove £6,000 from the bank while producing a much smaller expense in that period. Depreciation itself does not involve a new cash payment.
Loan repayments also need separating. The principal element reduces the outstanding borrowing rather than appearing as an operating expense. Interest is generally recognised as a finance cost.
Check repayment schedules instead of assuming the whole monthly payment has already reduced your reported profit.
Earlier Bills and Tax Payments Are Now Being Settled
Paying a supplier this month may settle an expense recognised last month. The payment reduces cash now without creating another expense.
This often explains a sharp bank balance decline after a business clears overdue supplier accounts. Compare what you owed suppliers at the beginning and end of the period.
Tax payments can create similar confusion:
- VAT: Under normal VAT accounting, VAT collected is generally a liability rather than sales income, and a VAT payment settles that liability. Other schemes can differ.
- Corporation Tax: A payment may relate to an earlier accounting period, rather than the month in which it leaves the bank.
- PAYE and National Insurance: Payments may settle payroll liabilities already recorded.
Keep a dated payment schedule. Interface Accountants’ VAT services can support accurate returns, helping you identify the VAT liability to include in your cash planning.
Money Taken Out by Owners Reduces Available Cash
For a sole trader, drawings reduce business cash but are not a business expense. Personal tax paid from the business account also needs separating from trading costs.
For a limited company, dividends reduce cash without reducing the profit shown in the profit and loss account. Repaying money previously lent by a director can also reduce cash without creating an expense.
Salary is treated differently, so owner withdrawals should not all be placed in one category. Each payment needs the correct accounting treatment.
A profitable month does not automatically mean the business can comfortably afford an additional withdrawal.
A Worked Example: £12,000 Profit but £6,000 Less Cash
Consider this simplified monthly reconciliation. It starts with profit before tax and assumes no other movements, including VAT or new borrowing.
| Item | Cash reconciliation |
| Profit before tax | £12,000 |
| Add back depreciation | +£1,000 |
| Increase in unpaid customer invoices | −£9,000 |
| Increase in stock | −£4,000 |
| Reduction in supplier balances owed | −£2,000 |
| Equipment bought outright | −£3,000 |
| Loan principal repaid | −£1,000 |
| Change in bank balance | −£6,000 |
The business earned a profit, but more money became tied up in customers and stock. It also settled supplier balances, bought equipment and repaid debt.
Notice that the reconciliation uses changes in customer, stock and supplier balances, rather than their closing totals. Using the whole outstanding balance would distort the explanation.
Turn the Explanation into a Cash Plan
First, reconcile the bank accounts and bring the bookkeeping up to date. Missing bills or duplicated sales can overstate profit. Professional bookkeeping support helps keep the underlying records organised and accurate.
Then prepare a rolling 13-week cash forecast. Enter receipts on realistic collection dates and payments on their expected payment dates, including wages, taxes, borrowing and planned purchases.
Test what happens if your largest customer pays two weeks late. If that creates a shortfall, act before it happens: chase payment, negotiate staged billing or reconsider spending that can wait.
Review the forecast weekly against actual receipts and payments. A repeated decline needs more attention than a planned equipment purchase that temporarily uses reserves.
Frequently Asked Questions
1. Does a falling bank balance mean the business is making a loss?
No. Cash can fall because of unpaid invoices, stock purchases, debt repayments or withdrawals, even when trading is profitable.
2. Will cash basis accounting make profit equal the bank balance?
No. It brings income and expense timing closer to cash movements, but drawings and borrowing still create differences. Limited companies cannot use the sole trader cash basis.
3. Does a new business loan increase profit?
The loan principal does not increase profit. It increases cash and creates a liability that must be repaid.
4. Can transferring money to a tax savings account reduce profit?
No. A transfer between the business’s own bank accounts changes where cash is held, not profit or total cash.
5. What should I ask my accountant to explain?
Ask for a reconciliation between profit and the change in cash, identifying unpaid customers, stock, supplier balances, taxes, asset purchases and financing movements.
Make Profit Available When the Business Needs It
Profit supports a business’s future, but cash determines whether it can meet the next payment. Establish where the money has gone, distinguish temporary timing gaps from recurring shortages, and plan around realistic collection dates.
