Sync Master keeps Shopify inventory and product data aligned with Google Sheets. Update stock levels, variant quantities, and metafields in bulk by editing a spreadsheet, then push changes to one or many locations in one click. Choose selective sync for quick edits or full sync for large catalogs. Schedule recurring syncs on a regular cadence, normalize values with built-in presets, and review every change before it goes live. For merchants managing large multi-location catalogs.
