What happened to Stocky
- February 2, 2026: Stocky was removed from the Shopify App Store, so it can’t be installed again.
- August 31, 2026: General access ended and the Stocky APIs stopped working, along with integrations built on them.
- September 1, 2026: Inventory management moved into Shopify Admin and Shopify POS.
- After the shutdown: read-only access was reported for at least 90 days, and Shopify contacted a limited number of merchants about an extension to March 2027.

Export what you need now
Historical data doesn’t move into Shopify automatically. While you still have read-only access, export as CSV:
- Purchase order reports
- Inventory history
- Historical cost data
- Any other report you rely on
Supplier records can’t be exported, so note your suppliers, lead times and minimum orders separately.
What Shopify’s built-in tools don’t replace
Shopify Admin now handles stock levels, transfers and purchase orders. What’s missing is the planning: forecasting demand, deciding how much to reorder and in which sizes, and knowing which shop should get the stock.
