The price based on weight allows buying an item at a cost defined by weight unit rather than a fixed unit cost. For example, to buy bronze bars at $1.22\/kg, the total cost depends on the actual weight of the bars received rather than on the number of bars.<\/p>\n

To enable this mode on an item, see the\u00a0Purchase price computing<\/strong>\u00a0section of the\u00a0Purchase tab<\/a>\u00a0page.<\/p>\n

 <\/p>\n

Insert a price based on weight item in a purchase order<\/h2>\n
    \n
  1. From the menu on the left, choose\u00a0Purchases -> Purchase orders<\/strong>.<\/li>\n
  2. Open the desired purchase order, then click\u00a0Edit<\/strong>\u00a0in the top right.<\/li>\n
  3. Add an item. In the selection list, the cost of price based on weight items is displayed with the suffix \/ <weight unit>.\n

    \"\"<\/p>\n<\/li>\n<\/ol>\n

    The created line inherits the Price based on weight\u00a0<\/strong>mode, the\u00a0Unit weight<\/strong>\u00a0and the\u00a0Weight unit<\/strong>\u00a0defined on the item.<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    Edit the line values<\/h2>\n

    On a price based on weight line, the fields behave as follows:<\/p>\n\n\n\n\n\n
    Quantity<\/td>\nEnter the ordered quantity. The\u00a0Net weight<\/strong>\u00a0and the\u00a0Total<\/strong>\u00a0are recalculated automatically.<\/td>\n<\/tr>\n
    Unit cost<\/td>\nExpressed in $ \/ <weight unit>. Editing it recalculates the\u00a0Total<\/strong>.<\/td>\n<\/tr>\n
    Net weight<\/td>\nRead-only as long as the\u00a0Quantity<\/strong> is 0. Once a quantity is entered, editing the Net weight<\/strong>\u00a0updates the stored\u00a0Unit weight<\/strong>\u00a0for the line and recalculates the\u00a0Total<\/strong>.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    The total of a line is calculated using the formula:<\/p>\n

    Total = Unit cost \u00d7 (1 \u2212 Discount) \u00d7 Quantity \u00d7 Unit weight<\/strong><\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    Split a price based on weight line<\/h2>\n

    The\u00a0Split<\/strong>\u00a0window keeps the \/ <weight unit> suffix on the\u00a0Unit cost<\/strong>. The created lines inherit the Price based on weight\u00a0<\/strong>mode, the\u00a0Unit weight<\/strong>\u00a0and the\u00a0Weight unit<\/strong>\u00a0of the parent line.<\/p>\n

      \n
    1. In a purchase order, select the desired line, then click\u00a0Split<\/strong>.\n

      \"\"<\/p>\n<\/li>\n

    2. Enter the quantity to split, then click\u00a0Confirm<\/strong>.
