The pricing matrix is, as its name suggests, the way you edit pricing for a product.
It presents all of the pricing as a tabular format, with product names on the left hand side and the pricing groups along the top. If the supply chain module is installed, you will also see RRPs and buy prices on the Matrix. All prices on the matrix are inclusive of VAT if applicable.
To change a price, simply click on a cell to edit it and type the new price. Pressing Enter will save the price, and escape will close the active editor. To remove a price, edit the cell and enter a blank price, then press enter or click the tick.
