Quick answer
Cash flow means money coming into the business and money going out of the business. Money comes in from customer payments and other business receipts. Money goes out for bills, expenses, owner withdrawals, payroll-like obligations, and other costs.
Money coming in and money going out
| Cash in | Cash out |
|---|---|
| Customer payments | Vendor bills |
| Invoice payments | Recurring expenses |
| Refunds or other receipts | Large planned costs |
| Owner contributions where relevant | Owner withdrawals where relevant |
Why timing matters
A business can have strong sales and still feel tight if customers pay later than bills are due. Cash flow focuses on when money is expected, when money is received, and when money must leave.
Cash flow is less about complicated theory and more about timing, visibility, and review.
How to review cash flow
- Review current cash balance against your own records.
