Please see comments below:
Balance sheet is incorrect by definition–assets do not equal liabilities plus equity.
There is no revenue line in the income statement yet there is a profit.
Cash flow statement is mislabled and does not tie to balance sheet or income statement.
Assumptions are insufficient. Need more detail on why numbers are the way they are by line item.
The assignment was not done. This is the requirement: Year 1: Monthly and year-end income statements and cash flows; and a year-end balance sheet.
You may redo this–I strongly suggest that you use a template provided.
