A word on our own behalf
Why are thousands of Swiss businesses still paying full price for software licenses?
At Keywi24 we specialise in verified software licenses: legal, function-tested and considerably cheaper than buying directly from the manufacturer. Our licenses come from company liquidations and surplus stock and, under the EU exhaustion principle (ECJ C-128/11), are freely tradable without restriction.
What this means for you: the same software, the same updates, the same support from Microsoft — simply at a fair price. And with our 90-day support you are never on your own should anything go wrong during setup.
