Net assets are all the assets your business has (e.g. inventory, equipment, land, property, accounts receivable and cash) less its total liabilities (loans, accounts payable, long term debt, etc).
So if your business had $100,000 in property, $200,000 in cash, $200,000 accounts receivable and total debts of $300,000, then it would have net assets of $200,000.
