The rules are different depenging on what service/product you are selling and his home-country

In general:
- IF you are selling to the EU, and you dont add VAT, he will have to pay the VAT in his country.
- If you are adding VAT, you need to specify it on the invoice, since he only have to pay the difference between your VAT and the VAT in his country.
