Hello, Alison.
I'll lay down some details regarding the options you've mentioned. That way, you can decide which ones to go for in importing your Sage data to QuickBooks.
Before we dive into the options, Sage might have a tool to help you move your accounting data easily into QuickBooks Online. Alternatively, you can use the Dataswitcher (for Sage 50) to move your data.

That said, adding the opening balances depends on how many transactions you have from last year. You might encounter difficulties in closing them out if it's too many.

Importing the invoices might be a feasible option for you since you can review and categorise them accordingly. Plus, you also have the option to edit and change after importing them.

Connecting your bank account can also be an option for you. This is also an easier way to bring in your data since you can just review and categorise those transactions. This article can help explain more about the process: Connect your bank feeds using Open Banking.
It should also be noted that some banks let you download the transactions within the last 90 days. If you can't get those older transactions, then you'll want to use an Excel file.

After taking care of those invoices, you'll also want to record the VAT you already paid so they won't show up as due in QuickBooks:
- Go to the Taxes menu.
- Click the VAT tab.
- Under the Returns section, find and select the returns you've paid.
- Click Record payments from the Action columns.
- Enter the VAT payment details.
- Click Save.
