The box Sales Price List specifies whether this price list is to be used for Sales or Purchasing. If the box is checked, it becomes selectable in sales orders, for instance. If you uncheck this box, it automatically becomes a Purchasing Price List and available in purchase orders, for instance.
The box Tax incl. specifies whether the prices are gross or net prices (i.e. including or excluding value-added tax). metasfresh calculates the prices accordingly.
Optional: Select a Default Tax Category that will be set automatically when selecting the price list.
