Is it possible to import xls files containing lists of invoices into QB Enterprise? If not, can I import into QB Online and then import into Enterprise from there? If not, are there any 3rd party addins that will allow me to do this?
The good news is there are many applications that can help you upload the invoices into QuickBooks.
Please visit our Intuit Marketplace. You can search for the third-party applications that are most compatible with QuickBooks Desktop. Check out the reviews from the customers. This can help you decide the third-party app that suits your needs.
That information should get you on the right track. Please reach out to me if there is anything else I can help you with. I'll always be here to assist you. Have a good day.
