One Tool for Managing All Your Business Schedules With Genbook, you can spend less time on your schedule and more time on business.

The phone calls were driving Ray Chang crazy. His seven-employee company, Motorsport Lab, was hours into its first Groupon deal--a one-hour supercar driving session priced at $89, a whopping 82 percent discount--and the number of calls flooding the Boston office was out of control.

"It was mayhem," recalls Chang, whose company sells driving experiences in exotic cars such as Ferraris and Lamborghinis to New England- and Arizona-area marketing campaigns and events. "We were keeping track of all our appointments in Google Docs. When we sold 1,500 Groupons that first day, I thought, How are we going to make this work?"

The answer came from a massage. Chang had booked one several weeks earlier using Genbook, a new cloud-based service that lets small businesses automate their client appointments. Merchants integrate Genbook's BookNow button into their website, Facebook page or blog; the button links to a customized, real-time reservations page that features the business's logo, contact information, consumer reviews and related information.
