Issuing a partial invoice of a business order from Crm & Marketing section

To partially invoice a business order issued from Crm & Marketing → Offerings, navigate to Crm & Marketing → Orders and click the "show order details"

At this point, using the appropriate fields for the quantities to be invoiced, indicate for each order line the number of goods/services for which you intend to invoice.

Below, click the blue button "Issue invoice" to finish 'operation.

After the invoice is issued, the order will be listed as partially invoiced

and by re-entering the order details using the path explained above, the quantities of goods/services that have not yet been invoiced will remain billable.
