A couple of useful resources if you need to calculate VAT rates across Europe and Stripe's fees in each country:
http://jsonvat.com/,
https://stripefees.com/
- Determine rate based on
- phone number
- billing address
- self-declared location
- IP address
- Validate VAT IDs
- Fetch exchange rate info from the European Central Bank
You can find the code at https://github.com/wbond/vat-moss.js and https://github.com/wbond/vat_moss-python.I also wrote up a bit about dealing with registering for VAT MOSS, generating invoices, etc.
