GL Summary Report has hugely incorrect opening balances

Hi, AngieFF. DId you check your opening balances? If not, kindly edit this to match the transactions. You can find your account opening balances on a trial balance report, a balance sheet or a profit & loss report prepared immediately prior to when you started using MYOB. You can either ask an accounting advisor (such as your accountant) to prepare these reports, or find your account opening balances using your previous accounting software or paper-based records.
 

If you began using MYOB:

• at the start of your financial year, enter the opening balances of your asset, liability and equity accounts only. The opening balances of your income, cost of sales and expense accounts should be zero.
• at any other time of the financial year (for example, in September, when your financial year started in July), enter the opening balances of all your accounts.
