Buy Virtualmin Professional -> 10 Domains

Dear all.

I have a client who might be intrested in purchasing a subscription for 10 domains to start off with.
Now my question is the following.
Can I purchase the lisence on my companies name and use it for my local server AND use the same lisence on the local server located in his office as well. I ask you this because he will be using on his local server only 1 domain (just for web and aplication development ) and on my local server i have only 4 domains.

Not sure if I have explained my selfe . But basiclly I would like to “split” the lisence for 2 local servers. Mine, located in my office and his local server in his office.

Hoping to hear from you.
regards,
Paco
