I am in the UK and I need to record expenses for services provided from EU VAT registered companies from EU countries. 

What VAT rate should we choose for the reverse charge? Nothing? Zero? 20%?

Expenses can be things like a subcontractor offering development services from another country or 

The Zoho support articles on this are either incomplete or misleading (e.g. https://www.zoho.eu/inventory/help/uk-vat/vat.html#purchases or https://www.zoho.eu/inventory/help/uk-vat/vat.html#adding-a-contact). They have no examples for EU VAT expenses . I talked twice with Zoho support on the phone (and tried several times via chat) but they don't have a clue. They mentioned that it depends on the country and type of business which is non-sense. Our UK accountant unfortunately is not acquainted with Zoho and how Zoho treats reverse charge 

Any ideas how this should be dealt with?
