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? Public and private sector are available in any country. The procurement process does not change — your jurisdiction's currency, tax, thresholds, rules and documents are configured when you sign, before you go live.
Tell us the region and the sector and you will see your own thresholds, currency and documents — not a generic sandbox.
