This article presents the assignment of clients to commercial advisors for an Asian technology company, which has multiple profiles of clients and advisors, in such a way that demand is satisfied with the most appropriate profiles, and a plan is established of hiring for new consultants. This was achieved thanks to a mixed whole programming model, which allowed us to model with the characteristics and restrictions established for commercial advisors and clients an optimal plan of account assignment. With this, it was possible to assign the commercial consultants who are currently hired and the contracting plan necessary to cover the totality of the demand that the organization owns is established.
