Why do profitable businesses still run out of cash?
Profit on paper is not cash in the bank. Customers pay slowly, expenses arrive all at once, or growth outpaces working capital. A rolling 13-week cash flow forecast shows the gaps weeks ahead, while there is still time to act.
Ask a small business owner what keeps them up at night and the answer is rarely profit. It is cash: will there be enough on Friday to make payroll? The two are not the same thing, and learning to manage the difference is the most valuable financial habit a small business can build.
Why profitable businesses still struggle
Cash flow problems kill profitable businesses. A company can be earning solid margins on paper while simultaneously running out of money because customers pay slowly, expenses hit all at once, or growth outpaces working capital. Every new order means buying materials and paying staff now, and getting paid later.
The 13-week cash flow forecast
The most important habit is maintaining a rolling 13-week cash flow forecast. This is not a profit and loss statement. It is a week-by-week projection of cash in versus cash out. Updating it weekly forces you to see problems before they become crises, not after.
- List your opening bank balance for the week.
- Add the cash you expect to receive, based on invoices that are actually due, not on hope.
- Subtract every payment you know is coming: payroll, rent, suppliers, taxes, loan payments.
- Write down the closing balance and carry it into the next week.
- Each Friday, replace the guesses for the week just ended with what really happened, and add a new week at the end.
Thirteen weeks is far enough ahead to arrange a line of credit or negotiate with a supplier, and short enough to stay accurate.
Accelerate receivables
On the receivables side, implement net-15 or net-30 payment terms and enforce them. Send invoices immediately upon delivery or completion, not at month-end. Offer a small early payment discount (1 to 2%) if cash is tight. For larger projects, bill in milestones rather than at completion.
- Put payment terms on every quote and invoice
- Follow up the day an invoice becomes overdue, politely and in writing
- Make paying easy: e-transfer, card and pre-authorized debit
- Ask for a deposit on custom or large orders
Stretch payables intelligently
On the payables side, negotiate payment terms with your suppliers. If you are on net-30, ask for net-60. Pay on the last day terms allow, not early. This is free short-term financing you may not be using. Just do not stretch so far that you damage relationships or trigger late-payment charges; a supplier who trusts you is worth more than an extra week of float.
Using a line of credit correctly
When you do need external capital to bridge a gap, a business line of credit is the most efficient tool. Used correctly, a line of credit lets you draw funds when receivables lag, then repay as collections come in. The cost is only on the outstanding balance, making it far cheaper than term debt for short-term gaps.
The mistake is using a revolving line to fund something permanent, like equipment or a renovation. That belongs on a term loan with a fixed repayment plan.
A short monthly routine
- Weekly: update the 13-week forecast and review overdue invoices
- Monthly: compare forecast to actual and ask why they differ
- Quarterly: review your credit limits and whether your terms with suppliers and customers still make sense
