How do I reimburse employee in Core payroll?

Hello, MEXP.

I'd be glad to provide you the steps on how to create reimbursement for an employee.
First is you need to add a reimbursement pay type by following these steps:

1. Go to Payroll from the left menu, then click the Employees tab.
2. Select the employee's name.
3. In the Pay section, click Edit.
4. From the How  much do you pay the employee section, click the Add Additional pay link, then select the Reimbursement checkbox.
5. You may change the pay type name and/or enter a recurring amount 
6. Click Save and select Done.

Once done create paychecks using the new pay type. Here's how:

1. Go back to the Employees tab then select Run Payroll.
2. Choose the payroll schedule. You will now notice a new column for the reimbursement. 
3. Hit Preview payroll then click Submit payroll.
4. Select Finish Payroll.

You may change the account associated to the reimbursement type. You can do this in the accounting preferences from your Payroll settings.

You can customize the Transaction Detail by Account report to keep track of your reimbursement per employee. Here are the steps:

1. Go to Reports from the left menu, then search for Transaction Detail by Account.
2. Click the report name, then select Customize button
3. Group them by Employee from the Group By drop-down,
4. Choose reimbursement account from the Distribution Account drop-down.
5. Filter the employee's name in the Employee drop-down. 
6. Select Run report.
   
   Don't forget to save the custom report.
