DeltaSync — Inventory Sync

Keep inventory in sync from one store to many in real time and stop overselling.

DeltaSync keeps stock levels aligned across your Shopify stores. When inventory changes in your source store, DeltaSync updates the matching product in every connected store within seconds, matching items by SKU. Set an optional buffer to hold back safety stock on each target store. If an update can't be applied right away, DeltaSync retries it automatically, and built-in loop protection keeps the same change from bouncing between stores — so quantities stay accurate without spreadsheets.

• Real-time inventory sync from one source store to many connected stores
• SKU-based product matching across stores — no spreadsheets or CSV imports
• Optional safety-stock buffer held back on the target store
• Failed updates are retried automatically until they apply
• Loop protection stops the same change syncing back and forth
