When we choose the option Services(Standalone) as a Sale to VAT registered Customer in EU, it does not show in the Box 8, but if we choose as Goods(and related services) it appears in Box 8

We usually file EC Sales before submitting VAT return on each calendar quarters. 

Should we manually put to indicate the EC Sales of services in box 8 or Choose Goods(and related services) when we post Sales invoices. Please advise us. Thank you.
