How do I get old version of QB back

I've got you covered, Bgservice. I'll provide details about QuickBooks's previous version.

If I may ask first, are you looking to revert to a previous version of QuickBooks Online(QBO)? or you're referring to something else?

Please note that QBO is a web-based platform that's often updated. Its features, interfaces, and functionality change over time. Thus, the option to revert to its previous version isn't available.

If you want to use the old invoicing layout, since May 6th, QuickBooks has updated its estimate and invoice format to help you land jobs, keep work moving, and get paid faster. Thus, switching back to the classic invoicing format is currently unavailable.

I've also added this article to help you learn about the new estimate and invoice layout so you can manage your business faster: New estimates and invoices in QBO.

Finally, you can see more about upcoming updates in QuickBooks by navigating this resource: QuickBooks Blog.
