True COGS — Cost of Goods Sold for Shopify

Shopify keeps one cost per item and no history of it. True COGS records what you paid on each shipment, recalculates your average cost, writes it back, and keeps every price permanently — the job Stocky’s average unit cost did before its shutdown.

• Permanent cost history. Every price you paid, kept — unit cost as of any date.
• Cost Guard. Catches any cost changed outside the app, with one-click restore.
• Year-end closing value. The number your accountant asks for every January.
