About Calendly
Calendly now bills, invoices, and emails — the scheduling link is just the entry point.
Calendly has spent recent releases assembling a contact layer and a billing layer around the booking it started from. Contacts can be imported and exported by CSV, created automatically from Typeform and Google Forms submissions, and now emailed directly through a connected account. On the money side, invoices can be created, sent and tracked with collection through Stripe, and the PayPal integration has widened to Venmo and more card options.
