A report fee can be added right when you are adding a new appraisal. This can be changed or edited at any time, and new fees can be added.
Start by clicking on the appraisal you wish to edit. On the far right, there is a Fees & Costs section. Click on the line item you wish to edit. In this case, we are going to edit the "Appraisal Report Fee" on line 2. See screenshot below.
While you're in there, you can edit the name and the rate. You can also assign an appraiser and set the percentage that will be their fee. You can also mark your appraiser as paid by setting a date. You can then choose to bill the client or not bill the client.
Be sure to Save your changes when you're finished.
