Build a Packaging BOM

A packaging bill of materials lists what it actually takes to pack one unit of a product, and totals the cost and weight for you.

Build the BOM

  1. From the Packaging Specs list (or the Units page), click BOM.
  2. If none exists yet, click Create BOM — this creates and activates version 1.0.
  3. Under Add Packaging Material, choose a material and enter:
    • Qty / Unit — how much is used per finished unit
    • UoM — each, g, kg, m, cm, or ml
    • Scrap % — expected waste, added to the effective quantity
    • Optional — tick for extras like a gift box that should show and cost per line, but stay out of the standard unit cost
    • A sequence and optional notes
  4. Add Line — the live cost panel updates with total cost and total weight per unit, based on required lines only.
  5. Review any warnings above the table — missing material cost, zero weight, or an inactive material — and fix them so the roll-up stays accurate.

You can keep multiple BOM versions per item, with one active default at a time — activate a different version in one click when your packaging changes.

Where this cost and weight show up

  • On the item — the Packaging Specification accordion on the item form shows a Packaging Cost (BOM) and Total Weight/Unit badge, or No BOM if none exists yet.
  • Landed cost — allocating by weight uses each item's per-unit packaging weight from its default BOM, falling back to quantity if there's no BOM. See Landed cost and GRN variance.
  • Manufacturing — completing a work order for this item automatically records what was consumed — see Track packaging consumption.
  • Sustainability dashboard — the BOM is what turns sales into a packaging footprint — see Monitor packaging sustainability.
