Instant results

Profit, ROI, break-even price, and risks update together.

Original models and verification trail

Order profit is reconstructed line by line, not reduced to one fee rate

The five tools use different fee structures, fixed costs, and decision questions. Defaults are editable starting points; every model exposes its verification date, official sources, and known limits.

  • 5 independent fee models
  • 15 official-source records
  • 3-step reproducible workflow

  1. 1Baseline: replace every example with dashboard, contract, or statement data.
  2. 2Stress: raise acquisition, returns, storage, or cross-border payment costs separately.
  3. 3Reconcile: compare the output line by line with the same SKU and reporting period.
