Small business cash flow: a practical guide to staying solvent

Cash flow is the movement of money into and out of your business over a period. It is not the same as profit. A profitable business can fail because the money it is owed arrives later than the money it must pay out. Understanding that gap is the whole job.

Why profit and cash differ

Profit is recorded when you raise an invoice. Cash arrives when the customer pays it. If you invoice on 30 day terms and your customers actually pay in 55 days, you are funding almost two months of work before the money lands, while payroll, rent and suppliers carry on as normal.

The three flows

• Operating: money from selling what you sell, minus the cost of running the business.
• Investing: money spent on or received from equipment, vehicles and other assets.
• Financing: loans, repayments, investment and owner drawings.

The levers that move cash the most

• Invoice the same day the work is finished, not at month end.
• Shorten payment terms for new and higher-risk customers.
• Take a deposit on any job with meaningful upfront costs.
• Chase overdue invoices on a fixed schedule instead of when you remember.
• Negotiate supplier terms so your outgoings are not due before your income arrives.
• Keep a buffer sized in weeks of fixed costs, not a round number.

Build a simple 13 week forecast

List each of the next 13 weeks as a column. Add expected receipts from named customers, then expected payments: payroll, rent, tax, suppliers, loan repayments. Carry the closing balance into the next week. You are looking for the weeks that go negative, because those are the ones you can still do something about.

Warning signs

• Your receivables aging report keeps getting heavier in the older buckets.
• You are using a credit line for routine running costs.
• You delay supplier payments to cover payroll.
• You cannot say from memory who owes you the most.

Late payment is a cash flow problem first

For most small businesses the biggest single cash flow lever is simply collecting what has already been earned. A consistent, professional follow-up process on overdue invoices is usually worth more than any cost cut. AI Money Recovery works from your own invoice data, keeps the follow-up consistent, requires your approval before anything is sent, and charges a performance fee only when money is actually recovered.

Tax and financing decisions vary by circumstance. Confirm anything with material consequences with your accountant.

Frequently asked questions

What is cash flow in a small business?

The movement of money into and out of the business over a period. It differs from profit because profit is recorded when you invoice, while cash arrives when the customer pays.

Why is my business profitable but out of cash?

Usually because customers pay later than your own bills fall due, or because cash is tied up in stock, equipment or work in progress.

How do I improve small business cash flow?

Invoice immediately, shorten terms for risky customers, take deposits, chase overdue invoices on a fixed schedule, and negotiate supplier terms.

How much cash buffer should a small business hold?

Measure it in weeks of fixed costs rather than a round figure. Many advisers suggest at least a few months, but the right number depends on how predictable your income is.
