Do any of the quickbooks packages let you have a profit analysis on a per invoice basis?

Greetings, alex. 

Currently, QuickBooks packages don't have profit analysis per invoices basis. I recommend using third-party applications to achieve this functionality. 

Additionally, we have several Profit and Loss reports for each QuickBooks package. Advanced and Plus subscriptions have 10 P&L reports, Simple Start has 8, and Essential has 9. These reports provide a summary of the financial health and status of a business 

Moreover, you can refer to this article to learn how to manage your invoices in QuickBooks Online:
