A story submitted by Bret Gregory: "I work for AccessPoint Inc., a privately-held CLEC offering integrated communications services to small- and medium-sized businesses. We use Cayenne for our internal accounting and reconciliation application. This application allows us to recognize uncaptured revenue streams as well as accounting margins and billing errors. In addition, Cayenne is used in our internal reporting application. These applications and thus Cayenne are central to the financial health of the company."
