I would like to find out what customization is required that Selling prices are automatically calculated based on the latest average cost but with a known and required GP% (not just a markup). Also, the latest average cost should be able to take into account landed costs. The landed costs in many cases in presented scenario are levies that should be automatically estimated until such time that the landed costs invoices arrive much later. Levies should be calculated and auto applied to inventory from the normal suppliers invoice. If anyone know perhaps the extent of customization that is required to achieve this requirement it will be highly appreciated.
