Negative. A connection is nothing more than the aforementioned bond of trust. It has nothing to do with billing. Of course there are paid apps that require a subscription in order to form a connection.

 But there are also many apps on the platform that do not, because you might already pay for these apps outside of the Zaikio platform. This is for example the case for a lot of on-premise software, which also connects to our platform, but runs their billing invidiually.
