In Tally.ERP 9, you can create different Price Levels and assign different Price Lists to these Price Levels. For example, you can create Wholesaler, Distributor and Customer as Price Levels and assign applicable Price Lists to these Price levels, as per your requirements, so that only the relevant prices and discount rates are used during entry of orders and invoices. Before you start creating Price Lists, you may decide to create Price Levels as required.
