If you have $20,000 in receivables on Jan 1, and $60,000 in receivables on Dec 31, you made $40,000 and loaned it to those that owe you money. If you have $20,000 more in product inventory at the end of the year than at the beginning, you made $20,000 and decided to buy inventory for future jobs with it. (Hopefully the inventory is usable and still relevant.)
If you bought a new truck or computer or desks or buildings, (things that last and provide you benefit longer than a year), you made money and decided to invest it in your future. Many business owners don’t make as much money as they had hoped, but have built/invested in their businesses to be greater profit generators in the future.
What “hidden profits” did you have last year?
