The Opportunity Products will be converted to Line Items in the Invoice. The newly created Invoice will be linked to the originating Opportunity using the **Opportunity** lookup field. The Opportunity Product **Line Item** lookup field will facilitate mapping the Invoice Line Item directly with the Opportunity Product Line Item. When an Invoice is created from Opportunities using the **Create Invoice** button, you can self-map additional Opportunity Line Item fields to the Invoice using a process builder.
