What customers are actually asking
Three concerns hide in the question: location (data physically in the EU), jurisdiction (a contracting entity subject to EU law), and transfers (what leaves, under which safeguards). Regulated buyers — banks, health, government — often require all three in writing; the rest ask because their own customers ask them.
The answer that closes
Hosting: EU regions of the major clouds satisfy the location line; sensitive verticals sometimes want EU-owned providers — a deployment option, priced. Entity: a Dutch BV as the contracting party puts the relationship under EU law and gives the privacy regime a local anchor — the same entity that signs, supports and invoices: the SaaS setup. Transfers: where data does cross — a US parent, global support — the standard contractual clauses and the transparency page name it plainly. Vendors that volunteer the map beat vendors that get audited into it.
The one-page response
Region and provider named; contracting entity named; sub-processor list current; transfer mechanisms stated; the security summary attached. Sector layers stack on top where you sell into them — health has its own chapter (that page), AI buyers add the act’s questions (that frame) — and the page itself becomes the sales asset it replaced.
