I've got you covered, TIN. I'm here to ensure you can import all your invoices to QuickBooks Online(QBO).
As I have checked, there are no current issues with importing invoices to QBO. If I may ask, is there any error that prompts you while importing? Knowing this will help me provide you with accurate information.
Moreover, QBO can have a maximum of 100 invoices with a 1,000-row limit per spreadsheet at a time. It could be the reason why some of your files aren't uploaded. You'll need to create a separate spreadsheet for the remaining invoices.
If the issue persists, I recommend accessing your QBO account in a private browsing window. Doing this will eliminate outdated files or data that cause system issues when using the program. You can use these keyboard shortcuts to launch a new private window.
Once everything looks good, you can clear the cache to fix any issues or use another supported browser when logging in to your account.
For more tips on preparing and uploading your spreadsheets for import, refer to this article: Import multiple invoices in QBO.
Additionally, I'm leaving you this article that provides steps to receive and record your customers' payments effectively so you'll have a balanced account: How to record invoice payments in QBO.
