We are working with Austrian Post as a reliable partner and ship all of our letters and packages with it. This shipping service use is the good network of postal and arise two advantages for you:
1) because some local knowledge from the postman and parcel delivery can be provided, there are no more problems with the delivery and
2) Ideally, one also knows his deliverer and that gives a sense of security.
In Switzerland, the cheaper shipping by post and overall handling is easier.
Invoices are issued to Switzerland without Austrian VAT (instead of for example 120 € 100 €), the Swiss Post Office will request for clearance and stands about 12 francs a the Swiss VAT of about 7 percent.
