How to adjust delivery dates in Shopify linked to the Google Merchant Center?

Topic summary

Issue: Delivery times auto-synced from Shopify to Google Merchant Center (GMC) keep reverting to 1–9 days, while Shopify’s “Expected delivery dates” setting is disabled/greyed out. Manual changes in GMC are overwritten by the Google & YouTube app sync. Images show the greyed Shopify settings (not essential to interpret).

Key clarifications:

  • GMC (product ads/feed) is separate from Google Search Console (GSC; indexing/structured data). GSC does not control GMC shipping settings.
  • If shipping is managed by third-party carriers/apps, that data often isn’t passed to GMC via feed apps.

Suggested approaches:

  • Disable automatic shipping settings in the Google & YouTube app; set shipping in GMC directly. Some shipping edits have been limited recently (GMC Next). A video guide for GMC Next was shared.
  • Use a different feed app (e.g., Multiple Google Shopping Feeds) to avoid the auto-override and manage shipping in GMC.
  • If using native Shopify shipping, and updates don’t reach GMC, contact Google’s Shopify app support.

Recent update/outcome:

  • OP still cannot resolve; reconnecting reverts to long delivery times.
  • Another user reports a workaround using CedCommerce: upload products (took ~10 days), disable “upload shipping/returns,” then manually configure shipping/returns in GMC.

Status: Unresolved for OP; viable workaround via third-party feed apps. Open question: how to re-enable Shopify’s greyed “Expected delivery dates.”

Thanks for your reply, but it’s actually not the thing we are looking for. We are looking for: to adjust our delivery time in Shopify to 1-2 days, so the Shopify API feed connection won’t override/adjust the feed in Google to 1-9 days
