Assistance: Generate license text to purchase

I have a server in reverse mode and a client in listen mode.

All run from the CLI.

How do I generate the text needed to purchase a license?

Thanks again!

#2

"LIST LICENSES"

#4

Do I just use the serial number, or the name and number of devs?

#5

This is what I get
MacBookDev,s/n=00000000xxxxxxx,1 device

Do I use this entire string to generate the license?

#6

Yes
