If you are selling external goods or services to a client at no cost for your agency, you may want to set the Buy Price to zero. However, in Allfred, when the Buy Price field is left empty (or with zero value), it automatically uses the same value as the Price (for the client). To avoid this, you can set the Buy Price to a minimal value, such as "0.0001," so that Allfred recognizes it as an item with no actual expenses.

When the project is completed, or the expense/media item is closed, Allfred will calculate the final profit based on the actual expenses received and the invoiced amount.
