Recently, we wrote about John Silvani's Gravity Software which is peddling a financial application built on top of Dynamics CRM. Silvani is not the only one. Last fall, Rockton Software launched Rockton Connect. "Some in Microsoft question why we'd go through the trouble of writing a new accounting application in the Dynamics space when GP, AX, NAV, and SL exist," says owner Mark Rockwell. "My standard reply is 'because GP, AX, NAV and SL exist.'" And the product is for those outgrowing QuickBooks.
