Hi Henning,
Thanks for contacting us!
Most agencies purchase regular licenses for each of their clients and give them their purchase code, so their clients can register to our support forum – https://kriesi.at/support/register/ and start a new thread whenever they have a question or an issue.
Agencies also provide their clients with their ThemeForest username and API key – kriesi.at/documentation/enfold/updating-your-theme-files/ so they would insert them in Enfold theme options to receive auto updates.
If that is not what you meant, please elaborate in English, if you do not mind. If you would like to receive replies in German, please let us know so our German speaking moderators can help you in German :)
Best regards,
Yigit
