Shift4Shop: What It Is, What It Really Costs, and Who It Suits
Paid for by your card processing.
The short answer
Shift4Shop, formerly 3dcart, is a hosted ecommerce platform from the payments company Shift4. Its End-to-End plan costs $0 a month if you are a US business and process card payments through Shift4 at 2.9% + 30¢. Use another payment provider and the platform fee rises to as much as $229 a month.
It suits US stores with steady card sales and large catalogues. If you are outside the US, want your own payment provider or need clear published pricing, Shopify, WooCommerce or BigCommerce are safer choices.

What Shift4Shop is
Shift4Shop is the old 3dcart platform, bought by the card processor Shift4 and renamed in 2021. It runs your whole online store: storefront, catalogue, checkout, orders, shipping and marketing tools, all hosted for you.
Its business model is different from most rivals. Instead of charging a monthly subscription, Shift4 earns from processing your card payments. That is how it can offer a full platform for $0 a month.
Who can actually get the free plan
For UK readers this matters most: the free plan is a US offer. Shift4Shop’s site shows non-US visitors a message that the platform isn’t yet available in their region, so most UK and European sellers should look at other platforms.
What the free plan includes
What Shift4Shop really costs
Because both Shift4Shop and Shopify charge 2.9% + 30¢ on cards, the comparison is simple. Here is the total monthly cost at four sales levels.
The free plan does not make card processing cheaper; it removes the subscription. Fees for apps, premium extras and domain renewals can still apply.
When does leaving Shift4 Payments pay off?
Switching to another processor moves you to a paid plan listed at up to $229 a month. If your own processor is 0.5% cheaper than Shift4, you would need to sell about $46,000 a month before the saving covers that fee. Below that, staying with Shift4 is cheaper.
Pricing details that don’t add up
Shift4Shop’s pricing has changed several times, and many reviews still quote old plans. Here is what is published, what is out of date, and what to ask.
Some third-party sites also report extra charges for Shift4 Payments merchants, such as a yearly compliance fee and inactivity fees on unused card devices. We could not confirm these on Shift4Shop’s own pages, so ask about them before signing your processing agreement.
