Hey there, stewartforestrys.
Thanks for turning to the Community for support! I'd be happy to provide some information.
The QuickBooks Balance shows all the transactions that have been recorded in the system, where as the bank feed will show all the transaction in your account. The best way to address the differences between the amounts, would be to reconcile your account. For steps and information on how to reconcile your accounts, I recommend taking a look at this guide.
Having an accountant can be beneficial for you and your business, especially when it comes to reconciliation. You can add your accountant to your books by following the steps listed here. If you don't have an accountant, you can find one who has experience using QuickBooks near you by clicking here.
If you have any other questions, feel free to reach back out.
