Hi there, JessicaStratton.

I appreciate the detailed information. It could be that your client is recording a reimbursement expense billable to a customer. I'm here to provide further explanation. 

There are three ways you can record a reimbursement expense in QuickBooks Desktop. The most common method is recording an expense billable to a customer. Once added, the system creates the reimbursement as an expense and transfers it to the sales revenue account when invoicing the customer.

Let's create a test bill by following these steps:

1. Go to Vendors and choose Enter Bills.
2. Choose a vendor.
3. In the Expenses section, select multiple accounts. Enter the amount and a memo.
4. Select a customer and mark the Billable column.
5. Click on Save & Close.
   
   

    

   

    

Then, create an invoice to the billable customer:

1. Go to Customers and select Create Invoices.
2. Select the billable customer.
3. Choose the Select the outstanding billable time and costs to add to this invoice radio button and click on OK.
4. Click on the Expenses tab, mark all transactions, and click on OK.
   
   

    

   

    

   

    

   

    

The invoice will show you a Reimb Group item.
