+This module allows to display the original price before pricelist
+application. This can be completed by the
+'sale_report_crossed_out_original_price' module to display crossed
+prices on sale order report.
+
+In some cases, prices are based on several pricelists based on formulas
+and we want to display the base price in that case too. This beahaviour
+is configurable.

+Use Cases / Context
+===================

+To retrieve the same behaviour as on e-commerce website, users want to
+display the original price on sale order lines when price list are
+computing a discounted price.
+
+Configuration
+=============
+
+- In the Sale Order form, enable the display of 'Base Price' field.
+- Go to Sales > Configuration > Settings > Pricing > Pricelists and
+  choose a base price computation method.
+- By default, the base price will reflect the computation from discount
+  list price only.
