CRM: Do Clients Pay for these?

I had an interview yesterday and the recruiter gave me some tips about CRMs that are usually used. Since it's my first time trying out a different VA role, I'm planning to practice on a few - just to learn and know my way around them.

PAANO POOOO? hahaha.

Nag YT ako, pero gusto ko din kalikutin syempre para hindi lang puro theory. Kayo ba? What did you do at first? Balak ko mag free trial then cancel subscription nalang muna.

Then, paano po if kunyari natanggap ako. Do I just use the logins I used while practicing?
