Where do I start from to set up and record a current asset and other expenses transactions that have not been on the bank statement

Hi caroljbert,

It's great to see you're taking an active approach to getting all your transactions recorded. QuickBooks offers powerful reporting features, which provide valuable feedback based on the data you've entered. Keeping accurate records of your books helps us consistently produce accurate results. QuickBooks Online is all about giving you the power to manage your own books, so there are several ways to record these expenses. I'll be happy to assist you with this. 

The simplest way to record an expense is through the + New button. You'll be able to select Expense from the Suppliers column to affect a specific Category on a specified Date. For more complex transactions, the Journal Entry option allows you to easily affect several accounts as needed. If these are bank transactions that weren't picked up when you connected your accounts, you can also consider manually importing these transactions.

I'm here for you, so let me know if there's anything else I can do to help.
