Prepare for the month end
Check that you've posted all transactions for the month.
If you use the Product Valuation report, run this report now. You can't run this report retrospectively because stock movements in the new month affect the values. To produce accurate values, run it on the last day of the month.
If you use recurring entries, ensure you've processed all entries for the month.
Run Check Data. If there are any errors in your data, fix these before you continue.
Create a back up of your data filesand store it in a safe place. Name this backup 'Before Month End'. You can run Check Data and Backup within the Month End window.
