Sell internationally — EU VAT worked out for you, prices in the currencies you choose
Ship to any of the 27 EU member states and checkout charges that country's standard VAT rate, from the table that comes with the product — you don't research 27 numbers or maintain them. You can price in as many currencies as you sell in, and your storefront can read in up to 8 languages.

EU VAT is worked out for you. Reverse charge is still your call.
An order to an EU delivery address is charged that country's standard VAT rate, from the 27-country table that ships with Olmira — no external tax account to buy or connect. Outside the EU, the tax classes and rates you set yourself apply. Inside the EU it's the standard rate you get: a reduced rate for a specific product category is not applied. And checkout never asks a business buyer for a VAT number, so the reverse charge is never applied automatically — you can check a number live against VIES, the EU's own register, from your back office, but zero-rating the invoice stays your call.

Price it in their currency, ship it on your terms
Add the currencies you accept, mark one as base, and record the rate for each pair — every rate is kept, so you can see exactly which one priced which order. Prices are stored as exact integers, never rounded floats, so totals reconcile the way a bank statement does. Shipping is zoned by destination, with rates by weight or order value, and a country you haven't zoned for simply isn't offered at checkout — see accepting payments for how the charge itself is captured.
What it costs
No. Checkout doesn't ask a business buyer for a VAT number, so it has nothing to validate and treats the sale like any other, charging the destination country's rate. Deciding that a cross-border business sale qualifies for the reverse charge — and zero-rating it — is a call you make on the invoice.
Yes — set your storefront's geo-scope to global, EU-only, or a specific list of countries, and checkout enforces it before a customer reaches payment.
From the rates you record in your currency settings. Olmira keeps the full history rather than overwriting, so every conversion is traceable to the rate that was current at the time — but keeping those rates up to date is your call, not an automatic daily fetch.
