True COGS

Automatic weighted-average or FIFO cost on every receipt, with landed cost and a permanent history.

Shopify stores one cost per item, but purchase prices change with every order, so the recorded cost goes stale and your margins drift. True COGS fixes this at the source: when stock is received, enter what you paid and the cost is recalculated and written back instantly — weighted average or FIFO. Set every line of a shipment on one screen, and spread freight and duty for true landed cost. Every change is saved to a permanent history that is never overwritten, with CSV export.

• Detects every inventory receipt from purchase order transfers automatically
• Live weighted average preview as you type the cost you paid
• Writes the new average straight to Shopify's cost per item field
• Permanent cost history ledger — past averages are never overwritten
• Ask-me mode or auto-apply: you control how each receipt is costed
