May we keep the old look of invoices and estimates after Dec. 11th?

Thanks for bringing this to our attention, @Mir7.

Allow me to clarify things about these new invoices and estimates for rollout updates.

Please know that we constantly make changes to enhance our customer's experience with program features while using QuickBooks Online. Thus, we're gradually rolling out new updates that include the new invoice layout for different subscriptions.

As part of this update, some users will migrate to the new experience, and QBO will make this the default experience for all users and subscriptions soon. To continue using the old one, you can send this feedback to our Product Developers so they can consider this suggestion as part of future product enhancements. Here's how: 

1. Click the Gear icon and choose Feedback.
2. Enter your feedback Suggestion.
3. Press Next.

You can track the progress of your feature request in our Feedback forum.
