What is included in the month/year end closing package

The important closing information for non-profit are Income statement, balance sheet, cash flow, budget V. actual, financial summary report etc.

These are items l can quickly think of for now.

There will not be an 'income statement' in case of a non-profit organization, instead it should be an 'Income Expenditure Statement'. In case there are different projects/cost center, the income expenditure account, comparison of budget V. Actual, should be prepared based on such projects/cost centers. Documents related to expenses of capital nature, a trail balance or Journal Book can also be included.

I work for a non-profit and two of the quarterly and year end statements my board wants are the comparative balance sheet and the comparative income statement - using the same period from the previous year. I don't show last years budget as the statement has enough to review as it is. I comment on each line of the statements that 1)have a process change that accounts for the difference or 2) are +/- $3,000 (we are a successful non-profit with 30+ years behind us). We continue to call our statement the income statement tho it also has been called "Statement of Financial Position".

You didn't specify that it had to be just financial so, if you want to make the reports truly meaningful, you should aim for some non-financial indicators as well. Depending on the mission of the NFP, it could be people helped, meals cooked, houses built, phone calls answered, volunteers assisting, or whatever. Financials? It would be expected that you provide the generic stuff mentioned above. But you may need specific income, expenditure, or project items that have strategic value to the board. It might be donations or grants received, grants paid out. To be really meaningful it should have some comparisons with similar periods both in the current year and previous years, even over the last few years if relevant.

I volunteer as Treasurer for a small non-profit. In our monthly financials that we submit to the Board, we also include a list of bank balances, as there are a variety of accounts that support both restricted and non-restricted funds. The total per this statement ties to the cash line on the Balance Sheet, enabling the Board to understand what comprises the organization's cash position.
