How the Google Merchant Center vs Shopify calculator works, and how the two compare
Google Merchant Center is Google's free product feed service that lists your catalog across Google Search, Shopping, and YouTube. Google Merchant Center is free: free product listings cost nothing and Shopping ads are optional paid placements; checkout happens on your own store, so your platform and processor fees are unchanged. Shopify is the leading dedicated eCommerce platform in the US, which also sells in person through Shopify POS. Shopify Basic is $39 per month at 2.9% + $0.30 online with Shopify Payments (Grow $105 at 2.7% + $0.30); in-person processing is 2.6% + $0.10 with POS Lite included in every plan, and POS Pro adds $89 per month per location.
How they are similar: Where they overlap: both Google Merchant Center and Shopify cover selling online, which is what this calculator compares. In both cases the bill is driven by a percentage of each sale plus any fixed per-transaction fee, which is why your average transaction size changes the effective rate as much as the headline percentage does.
How they differ: Only Shopify offers in-person card readers and a full POS system, so that side of the business is not part of this comparison. Google Merchant Center operates as a complementary service rather than a direct payments or storefront competitor, while Shopify operates as a subscription platform where you pay a monthly plan plus payment processing. Google Merchant Center is a traffic channel, not a store: it sends shoppers to a storefront like Shopify, which still handles the cart, checkout, and processing fees. Shopify's strength is depth and ecosystem: the largest app store in commerce and true omnichannel selling, but third-party gateways trigger an extra 0.6% to 2% fee and app costs creep up at scale.
