If i accept a freelance job, can i still use personal license?

Thank you. i tried to search for this topic and i found several discussions (such as this one: License question for freelance work ), but i still don’t know which license will i use if i accept that freelance job in my case, i know the license i use must match my client’s if i work for her, but i don’t know which license will my client use, she says she never used unity before.
And thank you for your advice to ask unity through the support section, i’ll ask them later when they are online.
