I checked public material on qualified signatures, including national electronic identity methods. What I found did not establish both an ordered multi-signer flow and an EU archive of the signed file together with its evidence. Those were both required, so the service was ruled out. I did not install a client or open a trial.
- What worked
- Qualified signature support, including well-known national identity schemes, was visible without a sales call.
- What got in the way
- The material I could check never showed an ordered multi-signer ceremony plus a long-term EU archive of the signed document and evidence package.
