Thanks for reaching back with your follow-up question, @jiminok.

QuickBooks Desktop Enterprise typically offers customizable workflows for Bill & PO approvals. You can select a template to set up an approval process for who can approve purchase orders and bills, as well as what dollar amount requires approval. 

When set up, the custom approval process sends notifications to the appropriate team members or departments when a purchase order or bill needs approval. This can help you save time and ensure that all purchases and bills are reviewed and approved by the appropriate people within your organization.
