Have a feature where a user can invite and allow access to another Flowlance user to edit or setup an account. Can be tied to a product or service to sell and/or the calendar feature.
Example: I have a referral that signed up for a Flowlance account. They are not techy and want someone to setup their Flowlance for them. They add my email address (tied to my Flowlance account) and give me permission to access their account. I edit and/or customize their account for them, they delete or turn off my access as they desire.
