Just like blood nourishes the body, cash flow nourishes the business. Without blood, the body collapses; without cash flow, the business loses its ability to survive even though the profit report is still positive. Therefore, it is absolutely correct to say that cash flow is the “blood” of the business – determining its operational capacity, financial health and long-term development prospects.
Read the article below by Bizzi to learn more about the nature of cash flow, and grasp traditional management methods and especially automation solutions to ensure financial health.

To make it easier to understand, the table below summarizes the differences between the concepts:
Criteria | Cash Flow | Revenue | Profit |
Nature | Cash received or paid | Recorded sales and service value | The difference between revenue and expenses |
Time of recording | When money actually comes in/goes out | When the transaction occurs (accrual accounting) | After accounting for all costs and taxes |
Measurement | Actual solvency and liquidity | Business scale | Business profitability |
For example | Customers pay immediately or debt is not paid yet | Issue sales invoice | Revenue minus costs of raw materials, wages, etc. |

For example, when a company invests heavily in expansion, marketing, or M&A, the cash flow may be negative in the short term but bring long-term benefits. However, if the negative cash flow comes from core business activities (no revenue from sales), it is a sign of high liquidity risk.
