Track your true cost of goods per purchase order. Margin reports survive supplier price changes.

Collected facts
Shopify stores one cost per variant — a single current value, no history. Update it when a supplier price changes and you lose what you paid before, with no per-batch or per-supplier trail. CostLedger keeps a time-stamped ledger of every batch instead: each variant gets a moving-average cost timeline with the math shown in the app. Margin reports value each sale at the cost basis from its sale date, so margins reflect what each unit really cost. Alerts flag batches that squeeze your margin.
Structured evaluations
Rate only the dimensions you experienced. Use N/A when an axis does not apply.
Add a self-reported profile across any of the six axes. There is no overall score.
