Hi bcschoolsports.

QuickBooks Online allows you to customize and set up multiple templates that you can choose directly from your invoice. I'd be happy to go over this with you.

Since you're QuickBooks is only letting you edit existing templates and not make new ones I recommend doing some browser troubleshooting as there could be something happening that's preventing your QuickBooks from working properly. The first step would be to clear your cache and cookies for your browser. Once that's done I recommend opening QuickBooks again in a private browser such as Google Chromes Incognito mode. If that doesn't work sometimes trying a different browser all together can work also.

If these steps still don't fix the issue I suggest reaching out to our support team so they can take a deeper look. You can reach them by the following methods: Schedule a Callback or start a Chat: click (?)Help in the upper right in QuickBooks Online > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
Social Media: Facebook, Twitter, and Instagram.
Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET.

Have a great day!
