If you sell products to customers, you can include those product sales on invoices.
Steps
Ensure the product sale/order is marked for invoicing.
Complete the order (as applicable to your workflow).
Create an invoice for the customer.
Select the product sale/order from the list of invoiceable items.
Generate the invoice.
Open the invoice to confirm the product items appear in the line items.
Tips
If a product sale isn’t appearing as invoiceable, double-check it was marked for invoicing and is in the correct status.
