Who is the contractual partner for the "Deutschland-Ticket"?

You always enter the contract for the Deutschlandticket directly with the provider. Thus, you can only do the cancellation of subscription directly at the provider as well.

Through the cooperation of billyard with the provider, you can purchase the Deutschlandticket with a 5% discount depending on the type and budget of the mobility subsidy. The data of your Deutschlandticket is automatically transferred to billyard. You don't have to do anything else to receive the mobility subsidy your company has dedicated to the Deutschlandticket.

Currently, you can order the Deutschlandticket from the DSW21 traffic company (Dortmunder Stadtwerke). (see: How do I order the Deutschland ticket from DSW21?)
