Careful selection and effective management of supply and distribution channels is essential for the flourishing of any company in its area of business. Where as efficient supply channel ensures regular flow of raw materials to be processed for maximum production (output) the distribution channels are the outlets through which a firm markets its goods. Thus effective selection and management of the two is synonymous to success. In this work; an attempt was made to assess the effectiveness in the selection and management of supply and distribution channels as practiced by Dange Leather Processing Industry Limited; Sokoto. In all the thirty-five (35) structured questionnaires were randomly administered to the Company's channels members and responses obtained were statistically analysed. The major findings of this research are that bad supply and poor distribution channels leads to high production costs and low sales; hence less profit.
