Shift4Shop

Shift4Shop Runs the Storefront. We Build What Happens After Checkout.

Shift4Shop (the platform formerly known as 3dcart) is a hosted e-commerce platform built by Shift4, the payments company, with its own payment processing baked in. It handles catalog, checkout, and payment well on its own. What it doesn't do is keep your accounting, inventory, and CRM in sync with what's happening in the store, that's where we come in.

What we build on top of Shift4Shop

Orders posting to your books automatically. A Shift4Shop order becomes an invoice in QuickBooks or your accounting software the moment it's placed, with tax and shipping mapped correctly, instead of someone keying it in from an export.

Inventory kept consistent. If you sell through Shift4Shop alongside a physical location, a marketplace, or another channel, we sync stock levels in both directions so nothing oversells.

Payment and order data routed where it's needed. Since Shift4Shop's checkout runs on Shift4's own payment processing, order and payment status are already in one place; we pipe that into your accounting and fulfillment systems so a payment event actually triggers the next step, instead of sitting in the Shift4Shop dashboard.

Customer data into your CRM. New customers and their order history sync automatically to whatever CRM or email platform your team actually works out of.

A before and after

Before

A Shift4Shop store where orders are exported and manually entered into accounting once a day, and a separate payment report gets cross-checked against orders by hand to make sure nothing's missing.

After

Orders and their payment status post to accounting automatically as they happen. Nobody's cross-checking two reports to catch a mismatch, because there's only one system of record and it updates itself.

Running a Shift4Shop store that still needs someone to shuttle data around?

Tell us what's manual right now, orders into your books, stock across channels, payment data that isn't reaching the rest of your systems, and we'll build the fix. And if Shift4Shop isn't where the real bottleneck is, that's fine too, we'll look at whatever is.

Frequently Asked Questions

What is Shift4Shop?+
A hosted e-commerce platform, formerly called 3dcart, now owned and operated by Shift4, a payments processing company. It handles the online storefront, checkout, and payment processing, with Shift4's own payment system built in.
Is Shift4Shop the same as 3dcart?+
Yes. 3dcart rebranded to Shift4Shop after being acquired by Shift4. If you're still seeing "3dcart" referenced in older documentation, support threads, or your own account history, that's the same platform under its previous name.
How much does Shift4Shop cost?+
Pricing depends on your plan tier and sales volume, and it's tied to Shift4's own payment processing rates, which is a different pricing structure than platforms that let you plug in any payment gateway. Check current plan details directly, since this is exactly the kind of number that changes without much notice.
Where do I log into Shift4Shop?+
Through the Shift4Shop store admin login. If your account predates the rebrand, your login credentials carried over from 3dcart, same account, new name.
Can n-frames set up or build my Shift4Shop store?+
No, that's store setup, theme, and template work. We connect a Shift4Shop store you're already running to the rest of your business, accounting, inventory, CRM, so the manual work of moving data between systems goes away.
