Is it possible to attach a receipt to an employee reimbursement in payroll?

It seems like you can, you can either attach it next to their name, on employee center, by double clicking on ATTACH or you can double click their paycheck and attach a file there as well. 

For reference, I use QuickBooks Enterprise 20.0. 

Hi there, @wdcsliz

Currently, QuickBooks Online (QBO) don't have the option to attach a receipt to employee reimbursement. For additional information, you can refer to these articles: 

• What's reimbursement?
• Reimburse an employee. 

Also, you can generate a report to check your employee reimbursement.

Here's how:

1. Go to the Reports menu, from the search tab type Transaction Detail by Account.
2. Open the report and click the Customize button.
3. From the Report period drop-down arrow, select the transaction range.
4. In the Rows/Columns section, click Group By and select Employee.
5. In the Filter field, select the Distribution Account and choose the Employee Reimbursement account.
6. Click Employee drop-down and choose the name of your employee.
7. Select Run report.
