Paying for sub-memberships

So, I’ve read a lot of things through this forum and none seem to directly discuss my situation, so I was hoping I could get some clarification. What my client wants is for a company to have the ability to pay for an unlimited amount of memberships for their sub companies, which would then allow for them after payment to enter in names and emails for each company’s POC and would send an email that would allow them to login and finish filling out their profile. Can this be done and if so how?

I am pretty certain that s2M does not do that right from the box, however, I am not 100% but I think this plugin might help you:

(this is an affiliate link but only for record purpose, NOT for payment; in case it means anything for you).

I saw Krum describe this plugin and I think it sounds like what you are trying to achieve. If it is not exactly what you need, you might be able to ask the programmer to tweak it for you (if it only needs tweaking).

Good luck.
