But we quickly heard the same question from lots of people - are the imported bookings going to cost me? And the answer was yes. That stopped a lot of people from importing historical data. After all, you might have a thousand bookings to bring in, which means a heck of an invoice.
Now, imported bookings are free. Whether they're imported by iCal or Excel or some other format, they won't cost you anything. Your monthly invoice now shows a new line item for "imported bookings" and they'll be free like blocked-off time.
And keep sending feedback about the import process. We've fixed or enhanced dozens of things over the past week since everyone started using it. Let us know what else you run into that doesn't work or that hangs you up.
