You really can’t say if they can justify it or not. Only they can. If I can save 15 minutes per day, that would more than pay for $12/month. Time is your most valuable asset.
I do, however, have roughly 10 meetings per week. These are with potential clients, existing clients (for feedback), external consultants (legal), investors, etc.
We are a startup, and as such, we all wear 10 different hats. Which means doing sales, admin, business, etc.
Time is a flow not a stock. It is only worth what you get paid for it.
