In this paper we construct an incidence algebra of a poset associated to a presentation by a quiver and relations of a finite dimensional algebra. We provide an exact sequence relying the fundamental groups of the incidence algebra and the presentation. Moreover, we give an algoritm to calculate any fundamental group.
