Currently, reverting back to the old type of proposals and invoices in QuickBooks Online (QBO) isn't possible, @pakconst46.
The transition to the new invoice and proposal template is made to enhance your overall invoicing experience, providing a range of benefits such as improved customization options and more efficient tracking. QBO aims to cater better to your business needs and streamline your processes.
If there are specific features from the old layout that you would like to use, I recommend sharing your ideas with our product developers. They're interested in hearing from you and may consider your input in future updates.
Here's how you can share your suggestions:
1. Sign in to your QBO account. 2. Go to the Gear icon at the upper-right hand corner. 3. Select Feedback under Profile. 4. Enter your suggestions then click Next.
