Thanks for getting involved with this thread, karalquinn.
 

I can certainly understand how an ability to have Service Rep, PO#, and Service Date fields for invoices could be useful while using the mobile apps and have submitted a suggestion about it as of today.

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.
 

In regard to users being unable to find invoices, I'd recommend having them perform the troubleshooting steps shared in Giovann_G's post. If it continues happening, have them try uninstalling and reinstalling their apps. If they're still unable to locate invoices in their mobile apps after performing each troubleshooting process, you'll want to get in touch with our Customer Care team. They'll be able to pull up your account in a secure environment, conduct further research, and create and investigation ticket if necessary.
 

I'll be here to help if there's any additional questions. Have a great Monday!
