Combined sale and expense

Hi Catherine, thanks for posting on the Community

If you're using QuickBooks Online Plus or Advanced, you can use the billable expenses feature to create the expense and add this to your customers invoice. 

If you're on a lower subscription plan, we'd recommend contacting your bookkeeper or accountant for advice on recording this in QuickBooks. If you don't already have an accountant, you can find a QuickBooks certified ProAdvisor near you on our online directory.
