Foxco is a certified Shift4Shop partner with deep hands-on experience across the full platform — from custom theme design and advanced development to migrations, integrations, and ongoing optimization.

Did You Know?

Shift4Shop (formerly 3dcart) is one of the only enterprise-grade e-commerce platforms with a completely free plan for U.S. merchants who use Shift4 Payments — no monthly fees, no transaction fees, unlimited products. Most businesses have never heard of it. The ones that have are paying a fraction of what Shopify and BigCommerce charge for equivalent functionality.

Shift4Shop Services

Custom Theme Design & Development

Shift4Shop's default themes are a starting point, not a finish line. Foxco designs and builds fully custom Shift4Shop storefronts — fast, mobile-first, on-brand, and optimized for conversion. Custom layouts, product page architecture, category page design, and checkout flow optimization. Your store should look like your brand, not like every other Shift4Shop merchant.

Platform Migration

Moving to Shift4Shop from Shopify, WooCommerce, BigCommerce, Magento, or another platform? Foxco manages the full migration — product data, customer records, order history, SEO redirects, URL structure preservation, and post-launch validation. We've done this enough times to know where migrations break and how to prevent it. Your data arrives clean, your rankings survive, and your customers never notice the switch.

Migration Away from Shift4Shop

Outgrown the platform or need to move for business reasons? Foxco handles outbound migrations with the same care. We export your data cleanly, map it to the destination platform's schema, preserve your SEO equity through proper redirects, and get you live on the new platform without losing what you've built.

3dcart Legacy Support & Upgrades

Still running on a 3dcart store that predates the Shift4Shop rebrand? Foxco supports legacy 3dcart implementations — theme updates, integration fixes, payment gateway upgrades, and migrations to the current Shift4Shop platform. We know the old architecture and we know how to modernize it without breaking what's working.

Custom Development & Integrations

Shift4Shop's API is robust. Foxco uses it. Custom checkout flows, third-party ERP and inventory integrations, shipping calculator customization, loyalty program integration, wholesale pricing tiers, custom product configurators — if the platform supports it, we can build it. If it doesn't, we'll find a way around it.

App & Plugin Development

Need functionality that doesn't exist in the Shift4Shop app store? Foxco builds custom modules and integrations that extend the platform to fit your specific business requirements. Built to Shift4Shop's development standards, properly maintained, and documented so your team can understand what's running.

Shift4Shop SEO & Performance

E-commerce SEO on Shift4Shop requires platform-specific expertise. Foxco optimizes URL structure, category architecture, product page content, schema markup, site speed, and crawl efficiency — specifically for how Shift4Shop generates and serves pages. We've ranked Shift4Shop stores in competitive product categories and we know what the platform does well and where it needs help.

Conversion Rate Optimization

Traffic that doesn't convert is an expense, not an asset. Foxco audits your Shift4Shop store for conversion friction — product page gaps, checkout drop-off points, mobile UX issues, trust signal deficiencies, and pricing presentation problems. Then we fix them, test the changes, and report on the results.

Ongoing Support & Maintenance

Platform updates, security patches, integration maintenance, content updates, promotional campaign setup, and on-call technical support. Foxco offers ongoing Shift4Shop support retainers for merchants who want an expert on call without hiring a full-time developer.

Why Shift4Shop?

For the right merchant, Shift4Shop is genuinely the best platform available at its price point. Here's when we recommend it:

• You process payments through Shift4 — the free plan is legitimately free with no catch
• You need B2B features — wholesale pricing, customer groups, quote requests, and net terms are built in
• You have a large catalog — Shift4Shop handles unlimited products without performance penalties
• You need built-in features — blogging, email marketing, loyalty programs, and affiliate management come standard
• You're migrating from 3dcart — the platform upgrade path is mature and well-supported

Why Foxco for Shift4Shop

• Certified partner. We're not learning the platform on your project. We know it.
• Migration specialists. We've moved stores to and from Shift4Shop without losing data, rankings, or customers. That track record matters.
• Full stack. Design, development, SEO, and strategy — all in-house. No subcontractors, no handoffs, no surprises.
• Platform honest. If Shift4Shop is the right choice for your business, we'll tell you. If it isn't, we'll tell you that too and recommend what is. We'd rather lose a project than set a client up for the wrong platform.
• Long-term thinking. We build stores that scale. Not just stores that launch.
