How to use Landed Cost Allocation Workbench

Enter one shipment in a single two-decimal currency. Choose a basis separately for each fee, apportion exact cents by largest remainder, then inspect each line and per-unit acquisition cost.

1. Use the example as the schema; replace its labels and entered model assumptions.
2. Enter one shipment in a single two-decimal currency. Choose a basis separately for each fee, apportion exact cents by largest remainder, then inspect each line and per-unit acquisition cost.

Good to know

• Up to 50 positive-quantity goods lines and 20 nonnegative fees; amounts from 0 through 1,000,000,000 with exactly representable whole cents. Quantities are at most 1,000,000 and weights/volumes at most 1,000,000,000 in consistent user-chosen units. A selected basis must have a positive total even when its fee is zero.
• Goods cost is the entire line purchase cost. Weight and volume are entire line totals, not per-unit measurements. Equal-line allocation does not weight quantity. No rebates, foreign exchange, shipping quote, customs tariff lookup, tax eligibility or book posting.
• Local calculation with no upload, input persistence or outside lookup. Model JSON is limited to 30,000 characters and 10,000 values. Decimal quantities are strings with up to six places; count fields use plain JSON integers. Exact fractions are capped at 8,192 bits. The complete JSON output is limited to 1,000,000 characters; approximate numbers preserve their stored values. Unsupported states fail explicitly.
