Good morning, @tclark47988. 

Thanks for coming back and asking other questions about your situation. 

Yes, we'll let another user recommend an app for you that could help fit your needs. 

As for saving the invoice after editing it, you should be able to successfully do so by clicking Save at the bottom of the invoice. If you don't see this option, please share a screenshot of your page that you're editing the invoice on. 

I'll be waiting for your response!
