GMC Account Suspension due to Shipping and Tax Issues

Topic summary

A company’s Google Merchant Center account was suspended after policy warnings revealed incorrect tax and shipping data. The root cause: their GMC feed displays generic carrier rates instead of the negotiated UPS rates they actually charge customers through Shopify, creating a price discrepancy that violates Google’s policies (which require advertised shipping costs to equal or exceed actual costs).

Core Problem:

  • Shopify checkout shows accurate pricing using negotiated UPS rates (managed via a third-party app)
  • GMC feed displays lower generic shipping rates
  • This mismatch triggered tax calculation errors and account suspension

Attempted Solutions:

  • Connected Google & YouTube app to Shopify, which created duplicate product listings (900+ instead of 400+)
  • Manual state-by-state tax corrections (unsuccessful)

Recommended Approaches:

  • Apply a fixed percentage increase to GMC shipping rates to create a buffer above actual costs
  • Use third-party feed apps (Simprosys, Feed for Google Shopping) for more granular control
  • Delete and reconnect the Content API feed to resolve duplication
  • Manually verify rates using GMC’s shipping/tax calculator before requesting review

Status: Community members confirmed this is a known, longstanding issue with no perfect solution. The company plans to implement a fixed percentage increase and rebuild their product feed.

Hi there,

Our company has been using Google Merchant Center and Google Ads since 2021. We had a marketing company set up our accounts, import all of our products and managed all of the settings in GMC. We have not had any major issues with our account until the last few months. We received a policy warning because our tax information was incorrect. It appears that when the products were set up the tax information was not set up by the agency we hired (we have not worked with them in years and do not wish to go back to them.). To fix this we went in and corrected our tax settings state by state in GMC and requested a review. The review came negative and our account was then suspended. They sent us two emails, one with examples of the tax information still being incorrect as well as a second one finding issues with our shipping data. After looking into it further we came to realize that the tax was incorrect because the shipping price in the GMC feed is incorrect and thus was creating inaccurate pricing data.

After more digging we have realized that even though we have our GMC settings set to UPS Ground as the shipping option (and the one that we most commonly use) the feed in GMC is based on generic carrier rates and not the negotiated rate that our company receives (which fluctuates month to month based on shipping volume). We have used a Shopify supported app for almost 2 years, it manages our complicated shipping settings (negotiated UPS rate, $ per box fee, % cc fee, as well as other special cases that have a flat rate).

Our value on the landing page (shopify checkout) is accurate with what the customer pays but the GMC value in the data feed displays a much lower price. GMC seems to be very limited in its ability to layer shipping policies. I reached out to Google about this issue and was given this response - “you can indeed create multiple shipping policies in GMC to apply different shipping methods (carrier rates, item-based rates, or percentage-based fees) to your products but not simultaneously.”. Which seems to mean that we cannot have them all apply like we can in our Shopify checkout. They suggested the following - “you can achieve layered shipping rates using advanced cost tables. This allows you to combine different shipping rules and criteria to create a more customized shipping experience based on Price, Weight, Destination, or Number of items”. But that does not help us with the negotiated UPS rate or % fee. Adding Shipping attributes also seems to not be a solution since they are also limited to location, price and shipping/handling times modifications.

We were advised to add the Google and Youtube app into our Shopify Sales Channels and we connected our GMC account to it in an attempt to potentially fix the feed issue. But now its showing all of our products duplicated (we have about 400+ and now its 900+, so double what we currently have). We are not sure how to fix this either now - the current data source listed in GMC is Content API (but its showing 900+) products in the source line.

I understand that Google prefers to see a value that is equal to or more than what the real shipping price will be, not less. We have 500+ individual products and it seems like the only way to maybe do this is to manually modify the shipping price in GMC to be whatever the max price shipping could be? Which seems like it would be not only time consuming but also not reliable as a solution.

Does anyone have any suggestions on how we can make our GMC shipping values match more closely with what Shopify generates in checkout? And how to fix the product duplication in the Content API feed?

Changing the feed will not change or fix the shipping settings or tax settings. The reason is that the google and youtube app will submit the same courier based settings, which will most likely also have the discrepency.

The shipping discrepency is a known issue and unfortunately there is no fix, other then to inflate the costs in Google Merchant Center by adding a fix rate or percentage. But this is very inefficiant.

All I want to say is that there are many merchants in the same boat as you are, and this is a very common issue when using couriers with specific rates. How Shopify calculate shipping rates with couriers, are different from how Google does it. It’s just a known issue for many years.

So either set a fixed shipping rate that is equal or an overestimate.

Inflate the shipping rates in GMC with a percentage or fixed rate.

Or change how you setup your shipping rates at source, in shopify, then match in GMC.

Whatever option you choose, never ask for a review, until you have manually checked it matches, which you can do by going to GMC > products > click on a product > click on the tab shipping and tax calculator.

With regards to the duplication, delete any duplicate feeds in GMC > top right corner > cog icon > data sources

Hi @Alena_7Springs

I’m sorry you’re going this. This is a tricky situation!

Here are a few steps that should help you resolve both the shipping rate mismatch and product duplication issues in GMC:

Fixing the Shipping & Tax Issue:

  • Use a flat-rate buffer – Since GMC doesn’t support negotiated UPS rates, the best approach is to set a slightly higher shipping rate in GMC than the lowest rate customers would pay. This ensures compliance without undervaluing shipping costs.
  • Manually adjust advanced cost tables – While imperfect, setting tiered shipping rates in GMC based on price/weight might help approximate Shopify’s real rates.
  • Use a third-party feed app – Tools like Simprosys or Feed for Google Shopping allow more customized shipping settings that better reflect Shopify’s checkout calculations.

Fixing Product Duplication in GMC: Check for Overlapping Feeds – If you’re using both the Google & YouTube app and a separate feed app, they may be pushing duplicate product data. Keep only one active source (likely the Content API).

Hi, thank you for the input, the shipping/tax issue fixes are ones that we considered but most will not work for us. The flat rate is what we are going to try but we were hoping that there would be a more comprehensive solution between shopify and GMC, thank you for you suggestions. As for the overlapping feeds, there is only one from Content API that is recording duplicates, no other feeds. We are going to delete it and re-add the feed and see if that works.

Thank you so much for validating what we were guessing at. Its good to know that we are not the only ones dealing with this issue! We are going to try a fixed % increase and see if that remedies the issue. For the Data feeds there is only one that is showing products - the other is a review feed. I am going to try deleting it and then reconnecting and see if that removes the duplicates.

Hang in there! Hope you’ll be alright :slightly_smiling_face:
