Product Cost<\/strong> in iDempiere represents the internal value of inventory, not the selling price. It reflects what a product truly costs the business, is recalculated from real transactions, and ensures inventory valuation, COGS, and margin reporting stay aligned with reality.<\/p>\n\n\n\n

Where Product Cost Is Maintained<\/strong><\/h2>\n\n\n\n

Product Cost is not stored as a single number. Instead, it is maintained as a set of calculated cost records<\/strong> tied to the product and accounting rules.<\/p>\n\n\n\n

Each cost record is determined by:<\/p>\n\n\n\n

    \n
  • Accounting Schema<\/li>\n\n\n\n
  • Cost Type<\/li>\n\n\n\n
  • Cost Element<\/li>\n\n\n\n
  • Costing Method<\/li>\n\n\n\n
  • Product<\/li>\n<\/ul>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    This structure allows the same product to be evaluated under multiple accounting perspectives without conflict.<\/p>\n\n\n\n

    Role of the Accounting Schema<\/strong><\/h2>\n\n\n\n

    The Accounting Schema defines how costs behave globally<\/strong>. It controls the costing method, costing level, currency, and posting behavior.<\/p>\n\n\n\n

    Once the costing method is defined in the accounting schema, every product cost follows that logic automatically. The product itself does not override this behavior.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Because of this, product cost is always consistent across inventory, shipments, and accounting entries.<\/p>\n\n\n\n

    Understanding Cost Elements<\/strong><\/h2>\n\n\n\n

    Cost Elements explain what type of cost is being tracked<\/strong>, not how it is calculated. Each cost element represents a specific cost component,<\/p>\n\n\n\n

    Common elements include:<\/p>\n\n\n\n

      \n
    • Material<\/li>\n\n\n\n
    • FIFO<\/li>\n\n\n\n
    • Average PO<\/li>\n\n\n\n
    • Labor<\/li>\n\n\n\n
    • Burden<\/li>\n\n\n\n
    • Overhead<\/li>\n\n\n\n
    • Outside Processing<\/li>\n<\/ul>\n\n\n\n

      These elements coexist to support different costing and reporting needs.<\/p>\n\n\n\n

      \"\"<\/figure>\n\n\n\n

      Only the cost element aligned with the active costing method actively drives postings, while others remain available for reference and analysis.<\/p>\n\n\n\n

      How Product Cost Is Calculated<\/strong><\/h2>\n\n\n\n

      Product cost is built entirely through transactions. There is no manual \u201cset cost\u201d action in normal operations.<\/p>\n\n\n\n

      Cost increases occur when:<\/p>\n\n\n\n

        \n
      • Purchase Receipts are completed<\/li>\n\n\n\n
      • Purchase Invoices are matched<\/li>\n\n\n\n
      • Landed costs or freight are capitalized<\/li>\n<\/ul>\n\n\n\n

        Cost decreases occur when:<\/p>\n\n\n\n

          \n
        • Shipments are completed<\/li>\n\n\n\n
        • Inventory is consumed or issued<\/li>\n<\/ul>\n\n\n\n

          Each transaction adjusts the accumulated quantity and amount, which recalculates the unit cost automatically.<\/p>\n\n\n\n

          Reading Product Cost Fields<\/strong><\/h2>\n\n\n\n

          Inside the Product \u2192 Costs tab, the key fields explain how the cost was derived.<\/p>\n\n\n\n

          The Current Cost Price<\/strong> shows the system-calculated unit cost.
          The Current Quantity<\/strong> shows how much inventory contributes to that cost.
          The Accumulated Amount<\/strong> shows the total value behind the calculation.<\/p>\n\n\n\n

          \"\"<\/figure>\n\n\n\n

          These values update immediately after each relevant transaction.<\/p>\n\n\n\n

          Why Product Cost Differs from Sales Price<\/strong><\/h2>\n\n\n\n

          Sales price and product cost serve completely different purposes.<\/p>\n\n\n\n

          Sales price is driven by:<\/p>\n\n\n\n

            \n
          • Price Lists<\/li>\n\n\n\n
          • Discount Schemas<\/li>\n\n\n\n
          • Business Partner rules<\/li>\n<\/ul>\n\n\n\n

            Product cost is driven by:<\/p>\n\n\n\n

              \n
            • Purchase history<\/li>\n\n\n\n
            • Inventory movements<\/li>\n\n\n\n
            • Costing method logic<\/li>\n<\/ul>\n\n\n\n

              This separation ensures discounts, promotions, or negotiated prices never distort inventory valuation or financial accuracy.<\/p>\n\n\n\n

              Product Cost During Shipment Posting<\/strong><\/h2>\n\n\n\n

              When a shipment is completed, iDempiere does not look at the sales order value. It reads the current product cost<\/strong>, multiplies it by the shipped quantity, and posts accounting entries accordingly.<\/p>\n\n\n\n

              \"\"<\/figure>\n\n\n\n

              This explains why shipment postings often show amounts lower or higher than the sales order total. The system is posting cost, not revenue.<\/p>\n\n\n\n

              Impact of Costing Methods<\/strong><\/h2>\n\n\n\n

              The active costing method directly affects product cost behavior.<\/p>\n\n\n\n

                \n
              • FIFO uses the oldest available inventory cost<\/li>\n\n\n\n
              • Average PO recalculates weighted average after each receipt<\/li>\n\n\n\n
              • Standard Cost uses predefined values unless adjusted<\/li>\n<\/ul>\n\n\n\n
                \"\"<\/figure>\n\n\n\n

                In your case, the Average PO<\/strong> method explains the decimal-based cost values seen during shipment posting.<\/p>\n\n\n\n

                Business Value of Product Cost<\/strong><\/h2>\n\n\n\n

                This design ensures inventory and accounting always reflect reality. It supports high-volume operations, fluctuating purchase prices, freight-inclusive costing, and audit-ready financials.<\/p>\n\n\n\n

                Product Cost enables:<\/p>\n\n\n\n

                  \n
                • Accurate inventory valuation<\/li>\n\n\n\n
                • Correct COGS posting<\/li>\n\n\n\n
                • Reliable margin analysis<\/li>\n\n\n\n
                • Clear traceability from purchase to shipment<\/li>\n<\/ul>\n\n\n\n

                  Outcome<\/strong><\/h2>\n\n\n\n

                  After understanding Product Cost:<\/p>\n\n\n\n

                    \n
                  • Shipment posting differences are fully explainable<\/li>\n\n\n\n
                  • Inventory valuation becomes transparent<\/li>\n\n\n\n
                  • Margin reports become trustworthy<\/li>\n\n\n\n
                  • Cost audits require no manual reconstruction<\/li>\n<\/ul>\n\n\n\n

                    Product Cost becomes a living financial truth, continuously shaped by real business activity.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
