Q: Will my clients be able to login to their own 10 Web dashboard if I stack 10 codes and having whitelabel and ...
will they be able to reach out and ask you if any problems occur or do they have to text me and then I have to talk to you and the talk to the client again?
We don't ahve white label or client managment yet but it's in the roadmap and will be available soon. If you get 3 or more codes you'll get it for free when available.

Thank you. Does that mean my clients will be able to get support from you by themself? Could you reveal an estimate, when Appsumo deal will be over.?
