Yes, we can switch back to the previous version, Jaynee, since adjusting to a new format can sometimes be challenging, especially when you're familiar with the previous workflow.
First, could you clarify which purchase order format you’re referring to? Are you asking about the format within the purchase order itself, the navigation leading to the purchase order, or the updated User Interface (UI) for navigating to purchase orders? Providing additional details or screenshots will help us better understand your concern and provide the best solution.
If so, the new UI was designed to provide a more efficient, streamlined, and AI-enhanced experience. This update prioritizes making your accounting tasks more intuitive and user-friendly. While the underlying functionality for creating purchase orders remains unchanged, the appearance of the interface may differ. That said, the steps and outcome of creating a purchase order remain the same. It’s just that the navigation leading to the purchase order and the interface have changed, but the format itself has not been altered.

To switch back to the previous version, hover over the Settings icon and click on Switch.
