Why USD
One price list. No quiet FX markup inside the package. Your bank converts. We are not a payment intermediary.
What we show
On German, Spanish, and French pages you will see “about X €” next to the USD number. If the rate moves, the indication moves. The signed quote is still USD.
Questions
Can you invoice in EUR?
Not as the default. If a specific entity requires it, ask in the brief. That is a billing exception, not a new package price.
