Are you setting up or joining?
Both give you the same kind of login. The difference is which company you end up in, and only your employer can decide that.
Setting up your company?
Owners, operations managers
Create the account for your business. You become its first administrator and can invite the rest of your team afterwards.
Joining a company?
Crew, technicians, office staff
Your employer adds you. You need an invitation from someone already at the company — we cannot put you in it from here.
