Great idea. However, I think you need to be careful in the VAT area not to overpromise: I selected “selling from Switzerland to Switzerland” and your calculator quoted a VAT of 0%, which is of course false (selling stuff in Switzerland requires deducting 7.7% VAT).
My guess would be that you only cover VAT within the EU, but of course there are VAT regimes outside of the EU too; so “we also take care of VAT collection for you” does not seem to apply in all cases.
Our connected tax office figured out taxation concerning international transactions. Why and how different taxation rules apply depends on a couple of instruments and setups such as reverse tax charges, MOSS and others.
It basically burns down to fruits:
- charging the buyer with the applicable tax between fruits (company in Germany) and the buyer in country XYZ
- each buyer receiving an invoice (issued by fruits)
- the seller receiving a single credit note for all sales within that month targeting a German company (fruits)
We will have to clarify taxation as I can see from comments in this thread - thanks for your input!
VATMOSS would seem to be the way to go, note that you may not have visibility on all of the transactions of a party so you won't be able to determine when they cross the limit for VAT liability for their country.
