I already have a subscription to the "Deutschland-Ticket". How can I get the subsidy from my employer?

If you have already purchased a Deutschlandticket, you can upload the invoice or proof of payment, e.g. transaction from your bank account via the billyard app. (see also: What documents can I submit as proof of the Deutschland ticket?). You will then receive the subsidy from your employer for your ticket.
In order to receive the 5% discount, the existing ticket must be terminated at the previous traffic operation and then reordered via the billyard app for the following months at the new, discounted price.
The ticket must be ordered by the 20th of the month, at the latest, so that it is valid for the following month!
