Answer:
Short-version:
income Statement do not represent cashflow thus the 150,000 income is not the equivalent of 150,000 cash
Explanation:
The accounting uses an accrual basis to recognize earnings thus, when a company made a sale or perform their services it will face cycle of collection on these earnigns that will differ with the cycle of payment of the business with their suppliers.
Thus, while there will be an accounting earning of 150,000 our friend should look at the cashflow statement to check for the liquity of his business.
For example ifthe business purchase for 10,000 and sale for 15,000 a gain will be recognize for 5,000
but It will have to purchase stock again o replenish their inventory if it used the whole amount to purchase additional 15,000 inventory
His earnigns will still be 5,000 but available cash to pay their loans will be zero.
Also, is important to understand that these are budgeted situation and will differ to the real-life. This deviancy along with the fact that income do not represent a box with 150,000 cash at the end of the year makes the assumptions of our friend false.
