The same platform everywhere, with the currency, tax, thresholds, trade-agreement rules and document library of the region you choose — set at setup, changeable later. The regional edition is part of the licence, not a premium tier.
Somewhere else? The region profile is configuration, not code — tell us where you operate and we will tell you honestly whether Atlas already fits it.
Tell us the region and the sector and you will see your own thresholds, currency and documents — not a generic sandbox.
