Track cash weekly to protect payment dates and profit monthly to test the business model, then reconcile unpaid invoices, stock and equipment spending.
Short answer: Track cash position and the next 13 weeks of dated receipts and payments every week. Review profit monthly using consistent revenue and expense recognition. If you can look at only one during an immediate crisis, cash decides whether you can pay; profit decides whether the business deserves to continue after the crisis.
Profit and cash can move in opposite directions. You can invoice a profitable job today and wait 60 days for payment. You can also collect a deposit today for work whose costs and revenue belong later.
The bank balance is neither. It includes money reserved for tax, customer obligations and bills not yet paid. A large balance can coexist with weak cash availability and a loss.
Use the Two-Lens Operating Review
The Two-Lens Operating Review gives cash and profit separate jobs, then reconciles them.
- Cash: Frequency: Weekly, more often when tight; Core question: Can every dated obligation be paid?; Main records: Bank, receivables, payables and forecast
- Profit: Frequency: Monthly; Core question: Does sold work earn more than its full cost?; Main records: Revenue, cost of sales and overhead
- Reconciliation: Frequency: Monthly; Core question: Why did cash and profit differ?; Main records: Stock, debtors, deposits, assets, loans and tax
My position is that weekly profit reporting is false precision for most small businesses. Invoices, stock and accruals are often incomplete mid-month. Track the operating drivers weekly, then close a reliable profit view monthly.
What cash flow tells you
Cash flow records when money actually enters and leaves. The weekly review should start with cleared opening cash and show customer receipts, supplier payments, payroll, tax, debt, asset purchases and owner withdrawals on expected dates.
Separate available cash from restricted or committed amounts. A customer deposit may be needed for materials. Collected tax may be due to an authority. A supplier bill due Friday already has a claim on the balance.
Cash can improve temporarily for unhealthy reasons: delaying suppliers, collecting advance payments for loss-making work or borrowing. Label the source. An inflow is not automatically earned value.
Use cash to decide timing, collection, payment terms, working capital and whether a commitment is affordable now.
What profit tells you
Profit matches revenue with the costs associated with earning it under the accounting basis used. Gross profit tests the offer after direct cost. Operating and net profit show whether overhead and the wider structure are supported.
Profit can exist before collection when you invoice on credit. It can also reflect equipment cost over time rather than on the purchase date. This matching makes the business model visible but does not guarantee liquidity.
Review price, sales mix, direct cost, owner labour, overhead and one-off items. If classification changes, restate the comparison or note it. Otherwise, an accounting change can look like operating improvement.
Tax, asset and revenue-recognition rules vary by country, legal structure and accounting framework. Ask a qualified local accountant how specific transactions should be recorded.
Reconcile the movements every month
Start with reported profit. Explain the cash effect of unpaid customer invoices, unpaid supplier bills, stock changes, customer deposits, equipment purchases, borrowing, loan principal, tax payments and owner transactions.
Every material difference should have a name, amount and timing. “Cash is just lower” is not a reconciliation. Once named, it creates a decision: collect an invoice, change stock ordering, fund an asset differently or reserve tax sooner.
Do not expect every reconciliation item to be a problem. Buying useful equipment can reduce cash while supporting future profit. The decision depends on whether the timing was funded and the return is credible.
Worked example: Mossgate Equipment Repair
Mossgate repairs catering equipment for independent kitchens. In one month it invoices £14,000 and recognises £10,000 of wages, parts, travel and overhead. Accounting profit is £4,000.
Only £9,000 of customer cash arrives because £5,000 remains in receivables. Operating cash payments are £8,500, and Mossgate buys diagnostic equipment for £2,500. It opened the month with £3,000 in the bank.
- Opening cash: £3,000
- Customer receipts: £9,000
- Operating payments: -£8,500
- Equipment purchase: -£2,500
- Closing cash: £1,000
Closing cash is £3,000 + £9,000 - £8,500 - £2,500 = £1,000. The business made £4,000 of accounting profit but cash fell by £2,000 during the month.
The main differences are the £5,000 invoiced but not collected and the equipment purchase, whose accounting treatment may spread cost across periods. Operating payments also do not necessarily equal the £10,000 recognised expense because supplier timing can differ.
Mossgate should not conclude that profit is fictional or that the equipment caused a loss. It should chase the £5,000 according to terms, confirm asset treatment with its accountant and place the equipment payment in its cash forecast before buying. If the receivable arrives next month, cash improves without next month earning another £5,000 of revenue.
Run the weekly cash review
Choose the same day each week. Reconcile the bank, confirm opening available cash and check the next 13 weeks. Replace expected receipts with actual dates from customer conversations and invoice terms.
Review the largest five inflows and outflows, every overdue invoice and any week approaching the minimum cash threshold. Assign an owner and action date. Do not spend the meeting updating cells that should have been reconciled beforehand.
Run a delay case for the largest uncertain receipt. If moving it two weeks creates a negative balance, act now through collection, staged payment, cost timing or agreed funding.
Run the monthly profit review
Close sales, direct costs and overhead consistently. Compare actual gross profit and net profit with the prior month, budget and rolling 12 months. Investigate price, volume, mix and cost separately.
Adjust for owner labour when the accounts do not include a viable amount. A sole trader can show profit while earning less than the job would cost to replace.
Select one commercial change from the review: reprice an offer, correct a cost, remove rework or change the sales mix. A report that produces no decision is bookkeeping history, not management.
Watch the four common gaps
Receivables create profit before cash. Stock creates cash outflow before the related sale. Equipment creates a large payment whose accounting cost may be spread. Customer deposits create cash before revenue is earned.
Loans add cash without profit, and principal repayment removes cash without being treated like an ordinary operating expense. Interest is treated separately. Owner contributions and withdrawals also need clear labels.
These mechanisms explain most differences. Your accountant can identify the exact treatment for the business and jurisdiction.

Start the rhythm this Friday
This week, set one 30-minute cash review and build the 13-week dated view. Mark committed tax and customer money separately. At month end, close gross and net profit with consistent classifications.
Within five working days of month end, reconcile profit to cash and name every difference above a threshold you choose, such as £250 or 2% of monthly revenue. Take one cash action and one profit action. Repeat the rhythm rather than waiting for the bank to become alarming.
Frequently asked questions
Can a profitable business run out of cash?
Yes. It may pay stock, wages, tax or equipment before collecting customers. Fast growth can deepen the gap because each additional sale needs more advance cash. Profit measures whether revenue exceeds recognised cost, not whether the receipt arrives before Friday’s payroll. Put dated sales and payment assumptions into a rolling cash forecast. A profitable order still needs funding. If the gap recurs without growth or timing explanation, check whether profit excludes owner needs, debt principal or another material cash obligation.
Can a loss-making business have cash in the bank?
Yes. Borrowing, owner investment, customer deposits, delayed supplier payments or asset sales can increase cash while operations lose money. Label each inflow. A loan is not revenue, and a deposit for unfinished work is not fully earned contribution. The balance may buy time, but it does not validate the model. Review monthly gross and net profit and calculate when available cash runs out if losses continue. Change price, cost, mix or structure before financing becomes a substitute for commercial viability.
Is my bank balance the same as cash flow?
No. The balance is one point in time. Cash flow is movement over a period and the forecast of what arrives and leaves next. The balance can include tax, customer deposits and money needed for bills already committed. Reconcile it, subtract restricted and near-term obligations, then examine future dates. A healthy closing balance after a loan drawdown can conceal negative operating cash flow. Track each source and use, not the number alone, and retain the reconciliation date each working week.
Should I use cash accounting or accrual accounting?
That depends on local rules, eligibility, business structure and what management information you need. Cash accounting recognises items closer to payment, while accrual accounting matches income and costs to periods and can show receivables, payables and stock more clearly. Tax and statutory requirements vary and can change. Obtain advice from a qualified local accountant before choosing or changing basis. Regardless of basis, maintain a dated cash forecast and a profit view that helps you understand your offer economics clearly today.
How often should I check the bank account?
Check often enough to catch fraud, failed payments and an approaching shortage, daily when cash is tight. That does not mean making strategy from every balance movement. Hold one structured weekly review using reconciled data and a 13-week forecast. Automating alerts can help, but someone remains accountable for investigation. Monthly is too slow for a fragile new business with weekly obligations. A stable cash-at-sale business may need less attention, but tax and annual bills still require properly dated cash forecasts.
Why does buying stock reduce cash but not profit immediately?
Unsold stock is generally held as an asset rather than treated entirely as cost at purchase under accrual accounting. Its cost reaches profit when the related product is sold, subject to the applicable rules and adjustments. Cash leaves when the supplier is paid. This timing creates a gap, especially when stock turns slowly. Accounting and tax treatment varies, so confirm it with a qualified local accountant. For management, track stock units, cash invested, age and contribution so purchasing does not outrun demand.
Which number should I show a lender or investor?
Show both, with the assumptions and reconciliation. A lender needs evidence of repayment cash and may examine profit, debt service, security and forecasts. An investor may focus on unit economics, growth and cash runway. Do not select the number that looks better while hiding the other. Explain material differences and their timing and dates. Reporting requirements and financial promotion rules vary. Use accurate records and obtain qualified accounting, legal or regulated financial advice before presenting information for a specific transaction.
