BIA/Kelsey has just learned that business accounting software giant Intuit has acquired the online scheduling company Full Slate. The plan apparently is to connect Full Slate’s capabilities to another recent Intuit acquisition, the digital marketing services player DemandForce.

Intuit acquired Demand Force in early 2012 for a whopping $423.5 million. Terms of the Full Slate deal were not disclosed. Full Slate CEO Bill Lange tells us that Full Slate will be integrated into Intuit’s Small Business Management Solutions unit, and its online scheduling product will complement Intuit’s existing suite of small business solutions. DemandForce, which offers a digital marketing platform for small businesses, also resides withing the Small Business Management Solutions unit.

“We will stay focused on doing what we’ve been doing for the last five-plus years — building great product and providing outstanding service to our customers. But this acquisition opens a world of new opportunities — for both our customers and our team — that we couldn’t be more excited to explore,” Lange told us in an email message Wednesday night. Seattle-based Full Slate was formed in 2008.
