Scheduling meetings without the back-and-forth emails
Calendly is a must-have for anyone working and having meetings across timezones.
Where usually you'd send emails back and forth (send me some times you'd be available, I'd be availabel....), Calendly allows you to simply set up some times and dates that work for you, then converts them for your meeting partner to choose from.
If needed, Calendly will also automatically send calendar invites, set up a meeting or add a point to your to-do list. Added extra: Integrations with PayPal and Stripe allow you to take paid meetings! Great for consultants.
