You register with an EU country and an EU postal address. Your Stripe country must also be in that supported EU set. Terms ask for an EU trade register, VAT, and postal address in the EU.
EU countries supported at registration include the Netherlands, Belgium, Germany, Austria, Hungary, Luxembourg, Poland, France, and Spain. A non-EU register country is not possible in the app.
This is about company registration, postal address, and Stripe country. It is not a separate warehouse ship-from check in the product.
Buyers on Ordentic currently ship to the Netherlands and Belgium only. That is buyer ship-to context for suppliers, not an extra supplier warehouse rule.
That aligns with the supplier criteria. See:
