1) Many software companies suffer from "deal of the week syndrome" where sales brings in a new deal for an application in an untargeted industry that is unlikely to generate repeat business or additional sales. 2) Developing products for these one-off deals disrupts the product roadmap focused on a larger target market, delaying products that could generate much more revenue. 3) Customizing products for deals often requires subsidizing professional services, potentially losing money. 4) Chasing "deals of the week" turns the company into an unpredictable custom engineering shop rather than focusing on target markets with larger revenue potential.
