The data file is still in history mode. History has to be closed to start a new fiscal year.

Note:

• When a new company is created, the file is in history mode by default
• History mode allows entering the opening balances before starting daily transactions
• Opening balances will be balances in the company books before the fiscal start date in the program.
• Historical information includes opening balances for: accounts, vendor's and customer's outstanding invoices and payment information, employees year-to-date earnings, deductions and expenses and the quantity as well as value of inventory on hand
• You cannot go back to history mode, so make sure that you are done entering historical information before ending history
• Please contact your accountant or controller if you are not sure that all opening balances are entered

If you finished entering opening balances you can close history.

1. Make a backup of your data.
