Managerial accounting Many consumers are willing to spend large sums on products which produce immediate benefits. Expenditure on housing (including joinery) often involves substantial outlay, from which the expected savings are less obvious to individuals. Yet such investment is an effective way to reduce energy costs significantly. Thus, the company's marketing should focus on the potential savings in energy costs for homeowners over the long term. In order to support sales, MPO Fentres has developed products within the framework of sustainable development, from design to installation. Additional certification for the installation of windows obtained in 2011 is further evidence of the company's desire to provide a quality service. These certificates and service evaluations conducted by independent arbiters are highlighted by the company's sales staff in discussions with existing and potential customers. The sales force is therefore a very important element of the new marketing strategy and the launch of the triple-glazed windows.
