Did you do everything yourself with paper and pen, or did you use an accountant?
For things like the opening balances, an opening balance journal would be required. However, if you had an accountant, they may be able to provide you with a Trial Balance report which would make life a bit easier.
If you don’t have that, do you have a balance sheet from before using QuickFile?
This would be done as part of the payroll journal. There’s more information on those here.
When it comes to accounting, we can only really offer generic advice and how to use QuickFile. For more specific cases, I would recommend speaking to an accountant or bookkeeper.
