I don't like the new invoice format & estimates. How do I go back to the original?

Being in the old layout template is the best, as you know all the workarounds, Richards. Let me help you switch it back.

May I ask if you're using the Simple Start or Essentials plan? This plan has a limitation on switching back to the old layout template.

The plans that can switch back to the old layout are Plus, and Advanced. Let me show you how to switch back if you have one of these plans.

Here's how:

1. Go to +New.
2. Click Estimates.
3. Beside the Feedback button on the upper right of your screen. 
4. Click Old layout.
5. Select Switch to Old layout. 

Moreover, I'd love to share these articles that can help you with your estimates and invoices:

Keep me posted if you still have questions about switching the layout template. Have a lovely day, and take care always.
