Hello, fireman_pete.
Thank you for reaching out to the Community. You can export your invoice template from the 2020 QuickBooks Desktop to QuickBooks Online. However, please note that when you import the template into QuickBooks Online, you'll need to have a QuickBooks Advanced version. If you're not currently using QBO Advanced, you can upgrade your version to QBO Advanced.
On the other hand, you can utilize a third-party app to import the template into QuickBooks Online to make the process quick and easy. This way, you'll have everything you need right at your fingertips without hassle or confusion.
However, we cannot recommend a specific application to meet your needs. We kindly suggest that you utilize our store application as it may provide a suitable solution. Popular apps in QuickBooks.
