Intulon GMC Sync — Shopify app for Google Merchant Center
Google says $80 shipping.
Your checkout says $12.
Intulon GMC Sync connects your Shopify store to your Google Merchant Center account and keeps your Google Shopping listings accurate.
Intulon GMC Sync is a Shopify app that connects to your Google Merchant Center account and keeps your Google Shopping listings accurate: it publishes your real Shopify shipping rates, syncs live product availability, and can manage your product feed — one feed per country you ship to, prices matching checkout. It fixes what the built-in Google & YouTube channel gets wrong: guessed shipping, hidden in-stock products, and missing markets. Synced automatically and audited against live checkout.
Free plan • No credit card • Works with your existing Shopify shipping
Here's the problem — Google admits it
Your shipping never syncs correctly.
Google's own documentation says only your General shipping profile syncs — custom profiles "sync incorrectly and cause errors," and carrier or third-party rates "can't be imported." The result is overstated shipping that loses clicks, or understated shipping that triggers policy violations.
Real shipping rates
Weight brackets, discounted carrier rates, and Managed Markets checkout prices — published as exact Merchant Center services, per country, and audited to the cent against live checkout.
Availability that tells the truth
The channel marks sellable products "out of stock" and quietly drops them from ads. GMC Sync overlays your live Shopify availability so Google always shows what you can actually sell.
Every country you ship to
Products missing from France, Japan, or anywhere else? GMC Sync manages one feed per destination market, so your catalog actually appears where you sell.
Here's what you get
Set it once. It stays correct.
Hands-free scheduled sync
Rates, labels, availability, and your feed refresh automatically. Watch live progress and keep a permanent, per-run audit log.
Full product feed management
Take over the whole feed — prices, images, GTINs, variants, and stock — written straight to Merchant Center, with local-currency support where markets require it.
Safe by design
Every estimate overstates rather than understates, so you never violate Google's shipping policy. GMC Sync never touches services or feeds it doesn't own.
