Where Knowledge Meets Innovation
Track costs and margins with real-time, historical data and alerts.
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.
