How do i go back to my old invoice template?

I'll explain why your invoice template changed, kihel.

QuickBooks Online is in the process of transitioning from the old layout invoices to the new one. You can only switch back if you see in the upper right corner of your Invoices window the "switch to old layout" button. However, if there isn't, then it's not possible anymore. An alternative is to use your old invoice template. Here's how:

1. On the Invoice window, click the Manage icon.
2. Select Design.
3. Click Other templates.
