Shift4Shop To Shopify Migration Services In 2026

A Shift4Shop to Shopify migration has no official Shopify path, so we checked the tools and agencies that name Shift4Shop or 3dcart as a source.

Start with the detail that reframes the project: Shopify does not document a Shift4Shop or 3dcart migration path. Its help center migration section, at help.shopify.com/en/manual/migrating-to-shopify, names Amazon, Clover, Etsy, eBay, GoDaddy, Lightspeed, Square, Squarespace, Wix and WooCommerce. No Shift4 brand appears, and there is no first party Shopify importer either. Every real route off Shift4Shop runs through a third party, which is why picking that third party matters more here than for a merchant leaving Wix.

A second detail catches people out late. Historical orders cannot come across by CSV at all. Shopify’s own documentation routes them through migration apps or through the Order and Transaction APIs, so any plan assuming a spreadsheet export carries ten years of order history needs rewriting.

There is an irony worth noting. Shift4Shop’s own app store hosts Cart2Cart and Next-Cart, tools merchants use to leave, while Shift4Shop’s webmaster division advertises a free migration service running the other way, Shopify to Shift4Shop.

None of this means Shift4Shop is going away. Shift4 has announced no wind-down and the platform still sells four plans and takes new merchants. Merchants move because the free End-to-End plan is limited to United States merchants, because keeping it free means processing through Shift4 Payments at 2.9% plus 30 cents, and because a third party gateway instead costs $229 per month, per Shift4Shop’s own payments page. Our Shift4Shop versus Shopify comparison covers that trade.

Best Shift4Shop To Shopify Migration Services In 2026

1. Shero Commerce — A Published Price Range And Four Named Case Studies

Shero Commerce is based in Red Hook, New York and holds Shopify Premier agency status. More usefully for this job, it runs a dedicated page at sherocommerce.com/pages/3dcart-to-shopify-migration covering “3dcart / Shift4Shop”, which correctly explains that 3dcart was rebranded to Shift4Shop in 2020 after Shift4 Payments acquired it.

Shero is unusual in publishing a price. The range is $8,000 to $20,000, with a standard timeline of six to eight weeks and eight to twelve where custom integrations are in scope. A range that wide is honest rather than evasive: a few hundred SKUs on a stock theme sits at one end, an ERP feed and heavy customization at the other.

Scope covers products, customers and orders, URL mapping and 301 redirects, payment gateway reconfiguration, app replacement, the theme build and post launch SEO monitoring. That last item matters, because damage from a bad replatform surfaces in organic traffic weeks after launch, not on launch day.

Shero names its work: Painful Pleasures, STX, Memphis Drum Shop and Sarris Candies. It reports more than sixteen years in business, over 500 projects and a team of more than sixty five.

2. LitExtension — A Sixty Dollar Entry Price And Separate Pages For Both Platform Names

LitExtension, based in Hanoi, Vietnam, has built pages for both platform names rather than assuming merchants know they are the same thing. There is a Shift4Shop to Shopify page at litextension.com/shopify-migration/shift4shop-to-shopify-migration.html and a separate 3dcart page. It is a Shopify Partner with a listing in the Shopify App Store.

Pricing starts from $59 and scales with entity count, placing it in the tool bracket rather than the agency bracket. The model is hybrid: run the SaaS tool yourself, or hand the job over as a done for you service.

Data scope covers products with SKUs, variants, meta fields and images, categories, customers, and orders with full line items. Read the add-on list before budgeting, because 301 redirects, order ID preservation and smart collection mapping are paid extras. For a store with years of indexed category URLs, redirects are not optional, so treat that as base cost.

One honest gap: the Shift4Shop page does not list reviews or blogs among the entities it moves, so confirm the handling in writing if your store carries either. LitExtension was founded in 2011 and claims more than 300,000 migrations for over 200,000 customers.

3. Cart2Cart — Sixteen Years Of Automated Migrations, And A Listing Inside Shift4Shop’s Own App Store

Cart2Cart is the automated SaaS option with the longest history in the category, founded in June 2009. It maintains separate pages for Shift4Shop to Shopify and 3dcart to Shopify, plus a Shopify Plus variant, so the routing is explicit rather than a generic promise.

Its most interesting credential is where it is listed. Cart2Cart appears in Shift4Shop’s own app store at apps.shift4shop.com/cart2cart.html, and in the Shopify App Store. A merchant can install the thing that moves them off the platform from inside the platform they are leaving.

Pricing is calculator based, driven by entity counts, with a free demo migration so you can judge mapping quality first. Budget separately for search: the 301 redirect and SEO module is a $29 add-on rather than part of the base migration. The entity list covers products, categories, customers, orders, manufacturers, coupons and reviews through AirReviews, plus those 301 redirects once the module is purchased.

The company claims more than 500,000 migrations for over 200,000 customers. One practical note for anyone searching: the brand’s home is shopping-cart-migration.com, and that is the address to use for the demo.

4. Next-Cart — The Widest Entity List, Including Blogs, Reviews And CMS Pages

Next-Cart runs dedicated pages at next-cart.com/product/shift4shop-to-shopify/ and a 3dcart equivalent, plus hub pages for both names, and like Cart2Cart it is listed inside Shift4Shop’s own app store. It sells as a self service tool and as a managed service, in Standard, Managed and Custom tiers, with calculator pricing and a free demo.

The reason to shortlist it is breadth. Alongside products, categories, customers and orders, it documents blog posts, reviews, coupons, CMS pages, meta titles and descriptions, and URL redirects. That long tail is what an old 3dcart store accumulates and what generic importers quietly drop, and a merchant publishing buying guides since 2014 often has more value there than in the catalog.

Because meta titles and descriptions are in scope, the search side of the move is less likely to need a second pass, and with URL redirects in the same run it removes the most common source of post launch traffic loss.

The company claims more than a million migrations, over 200,000 merchants and 3,000 migration paths. It does not publish a head office address or name individual clients, so if you need a contractual counterparty in a specific jurisdiction, ask before buying.

5. MigrationPro — A Published Per Record Price And The Strongest Third Party Rating In The Category

MigrationPro, operating as Migrationpro LLC out of Dover, Delaware, documents the Shift4Shop connection precisely. Its help center at help.migrationpro.io walks through connecting to Shift4Shop or 3dcart using a REST API key, and its Shopify App Store listing names Shift4Shop explicitly. An API connection rather than a file export is the difference between a repeatable sync and a one shot dump.

Pricing is free to install, then one time per record, with the vendor stating most stores land between $49 and $299. A free demo covers ten products, ten customers and ten orders, enough to check that variants and custom fields land correctly before paying.

Migration scope covers products, customers, orders, collections, blog posts, discount codes, reviews, SEO metadata, images, URLs and 301 redirects. Redirects in the base scope rather than as an upsell matters against the other tools here.

On third party validation it is the strongest here: 5.0 stars from 185 reviews on the Shopify App Store, 97 percent of them five star. One quirk: the homepage does not name Shift4Shop, describing coverage as “30 plus more platforms”. The help center and app listing do name it, so do not rule it out on the homepage alone.

6. Optimum7 — Fifteen Years On The Platform, And Blunt About How Little Changed At The Rebrand

Optimum7 is based in Coral Gables, Florida, and its page at optimum7.com/migration/3dcart-to-shopify-migration says the quiet part aloud: “Shift4 acquired and rebranded 3DCart in 2020. The platforms are functionally the same under the hood.” That line tells you the team has looked at the data model rather than the marketing site.

Migration scope covers products with variants, SKUs and images, categories, customers, order history, coupons, reviews, blog content, 301 redirects and metadata. Reviews and blogs in the base scope again place it in the smaller group handling the long tail.

What makes Optimum7 structurally different from the pure migration shops is that it also runs a genuine 3dcart and Shift4Shop development practice. It can rebuild a store on the platform or move it off, a useful position to buy advice from if the question is not settled. A Shopify partner badge is displayed, tier not stated, and pricing is quote only.

One caveat to weigh: the migration testimonial on the page is anonymized, attributed to “David M., Sporting Goods Retailer”, so you will need to ask for referenceable clients directly rather than clicking through to them.

7. HulkApps — A Shopify App House That Migrates The Apps As Well As The Data

HulkApps is based in Chicago, Illinois, with teams in Canada, India, Greece and Bosnia. Its product page at hulkapps.com/products/shopify-migration-from-shift4shop notes that Shift4Shop was previously known as 3dcart, so the history is understood rather than glossed over. The company describes itself as a top tier Shopify Partner and maintains seven or more Built for Shopify apps.

That app portfolio is the reason to consider it here. The hardest part of leaving Shift4Shop is rarely the catalog. It is the small undocumented behaviors accumulated through platform features and add-ons, which have to be rebuilt as Shopify apps or theme code. A team that builds Shopify apps for a living has a shorter path from “our old store did this” to “here is where that lives now”.

The published scope reflects that: design, products, apps, orders, customers, content pages and media, and reviews, plus speed work, SEO redirects and analytics. Migration pricing is not published, so expect a scoped quote.

On scale, HulkApps claims more than 120,000 businesses served, over 250 staff and operations since 2012, and names Vinyl Me Please, Kylie Cosmetics and Hulu among its brands. Those are broad Shopify credentials rather than Shift4Shop ones, so weigh them accordingly.

8. StrategicDB — A Data Migration Specialist That Takes Gift Certificates And Newsletter Lists Too

StrategicDB operates from King City, Ontario, Canada, and its page at strategicdb.com/shift4shop-data-migration-services/ states it has moved stores from Shift4Shop to BigCommerce, Shopify, Adobe Commerce, Wix and WooCommerce. Being destination agnostic is a quiet signal of competence: the hard work is reading Shift4Shop’s data correctly, and a team that has done that several ways has read it carefully.

It is a pure data migration specialist rather than a build agency, the right shape for one common scenario. If the theme is designed elsewhere, or built in house, you do not want to pay agency rates for a rebuild you did not ask for.

The entity list is the broadest of any agency here: products, customers, orders, reviews, coupons, blogs, newsletter subscribers, gift certificates and custom fields. Gift certificates get abandoned in a rushed migration and then generate support tickets for a year, because customers hold outstanding balances and expect them to work.

Pricing depends on volume and complexity and is not published. The company was founded in 2014 by Anna Kayfitz, named publicly as founder, which is more transparency about who stands behind the work than several larger vendors offer.

9. Web Ecommerce Pros — The Deepest Library Of Shift4Shop Pages Of Any Agency

Web Ecommerce Pros has invested more page real estate in Shift4Shop than anyone here. The migration page at webecommercepros.com/pages/shift4shop-to-shopify-migration covers “Shift4Shop (3DCart)” by both names, and sits alongside a family of Shift4Shop pages covering expert services and inbound migrations too. Shopify Expert badges are displayed, tier not stated, and pricing is not published.

The process is documented as thirteen steps, more procedural detail than most competitors publish, and the data scope covers products, collections, pages, blogs, orders and customers. Five testimonials name real client domains, including languagelizard.com, justsweatshirts.com, hubcapmike.com, txpowersports.com and ruvanti.com. Domains you can visit are worth more than an anonymized quote.

There is a caveat to raise plainly, without reading anything sinister into it. The published address, 1910 Thomes Avenue in Cheyenne, Wyoming, is a registered agent address rather than an operating office, and the same legal entity also trades under a second brand. Neither is unusual for a distributed agency, and neither says anything about the quality of the work.

It does mean you should ask directly before signing: who will do the work, where are they located, and which brand is the contracting party. Get that in writing alongside the statement of work.

10. 1Digital Agency — Two Hundred Migrations, And Honest Scoping About When Not To Move

1Digital Agency, based in Philadelphia, Pennsylvania, is a Shopify Plus Partner. Its Shift4Shop page at 1digitalagency.com/shift4shop-web-design/ offers “Migrations Onto or Off Shift4Shop” and, in its own words, honest scoping for merchants weighing BigCommerce, Shopify or WooCommerce when Shift4Shop is not the right fit. It also does legacy cleanup of 3dcart era code for merchants staying put.

That two directional posture is useful at the assessment stage. An agency willing to tell you the move is not worth it has a different incentive structure from one that only sells migrations.

Pricing is a fixed price per phase plus a time and materials envelope for variable work, set after assessment, with Shift4Shop work quoted from $185 per hour. Publishing an hourly rate at all is unusual here and makes it easier to sanity check a quote against the hours implied.

On track record, the agency reports founding in 2012, more than 400 brands served, over 200 migrations completed, more than 300,000 products migrated and a team of over fifty. It does not publish named Shift4Shop clients, so the migration count is portfolio wide rather than platform specific.

11. Pelican Commerce — Eighteen Named Portfolio Builds You Can Click Through

Pelican Commerce works out of Windermere, Florida, and its page at pelicancommerce.com/3dcart-to-shopify-website-migration-service/ is headed “Shift4Shop To Shopify”, resolving the naming confusion up front. No partner tier is stated and no pricing is published.

The published data scope is detailed enough to be checkable, more than a lot of agency migration pages manage. It covers products with titles, descriptions, categories, images, vendors, SKUs and UPCs, variants, SEO data, customer accounts, orders, taxes, coupons and content pages. Vendors and UPCs called out individually matters to anyone with supplier data attached, because those fields vanish silently in a generic CSV round trip.

Taxes appearing in the scope list is another practical detail. Tax configuration does not migrate itself, and a store selling into multiple states with product level overrides needs that mapping handled deliberately rather than rebuilt by hand.

The strongest evidence here is visual. Pelican publishes eighteen or more named portfolio projects with screenshots, among them Paramount Outdoors, Pleated Boutique and Etta + Billie. You can open those stores and judge build quality yourself, which beats any testimonial. Years in business are not stated on the site.

12. The Genie Lab — A Shopify Plus Agency With A Step By Step Public Playbook

The Genie Lab carries Shopify Plus Agency and Shopify Partner badges and has a UK and US presence, though it does not disclose a head office. It has been trading since 2011 and names Cosabella, Bonds Packaging and Elle Summers Studio among its clients.

Its Shift4Shop qualifier is different in kind from the others here, and it is worth being plain about that. There is no Shift4Shop service page. What exists is editorial: a step by step guide to 3dcart to Shopify migration at thegenielab.com/blogs/tech-corner/3dcart-to-shopify-migration. The migration work itself sits under the agency’s general Shopify migration service rather than a platform specific offer.

That is a weaker signal than a dedicated service page, but it is not nothing. Writing a usable guide requires having done the work, and a public playbook gives you something concrete to interrogate on a sales call.

Pricing is not published. Given the Plus credentials, expect a full build engagement rather than a data move, and shortlist it if your destination is Shopify Plus and you want an agency that carries the store forward after launch rather than handing it back.

How To Choose A Shift4Shop To Shopify Migration Service

Does The Provider Actually Support Shift4Shop, Or Just Shopify?

This is the first filter and it eliminates most of the market. The large majority of Shopify migration agencies do not list Shift4Shop as a source at all. They list Magento, BigCommerce, WooCommerce and Lightspeed, the sources Shopify itself documents. Shift4Shop is not on that list, so most agencies never built the connector or the expertise. The check is quick: search the provider’s own site for “Shift4Shop” or “3dcart” and see whether a named source page comes back. A rep saying “we can handle that” is not the same as a documented path.

Do You Need A Tool Or A Full Agency Build?

The two ends of this market barely overlap on price. Tools move data and start around $49 to $59: MigrationPro puts most stores between $49 and $299, LitExtension starts from $59. Agencies rebuild the storefront, remap URLs, replace apps and reconfigure gateways, and start in the thousands: Shero publishes $8,000 to $20,000, and 1Digital quotes Shift4Shop work from $185 per hour. Pick the tool if the theme is built separately and the catalog is clean. Pick the agency if the store has custom functionality, if nobody internally owns the SEO, or if you cannot afford to find a mapping problem after launch.

What Happens To Your Blogs, Reviews And Gift Certificates?

Products and customers are the easy part. What gets lost is blog posts, product reviews, coupons, CMS pages, newsletter subscribers and gift certificates, and a store on 3dcart since the early 2010s usually has all of them. Only a few providers document that long tail properly: Next-Cart lists blogs, reviews, coupons and CMS pages, StrategicDB adds newsletter subscribers, gift certificates and custom fields, and Optimum7 covers reviews and blog content in its published scope. Gift certificates deserve attention, because they represent money customers have already paid you. If they do not arrive, you will honor them manually, one support ticket at a time.

Who Owns The 301 Redirects?

Losing redirects is the most common cause of a traffic collapse after a replatform, and it is avoidable. Shift4Shop and Shopify use different URL structures for products and categories, so every indexed URL needs a mapped destination before launch day. Read the pricing model carefully, because redirects are treated inconsistently. Cart2Cart sells its SEO and redirect module as a $29 add-on. LitExtension treats redirects as a paid add-on alongside order ID preservation. MigrationPro includes URLs and redirects in its documented scope. Agencies fold the work into the project. Whoever owns it, get the mapping file reviewed before go live.

Can You Get Historical Orders Across?

Yes, but not the way most people assume. Shopify’s own documentation routes historical orders through migration apps or through the Order and Transaction APIs. There is no CSV path for orders, so a provider promising to “just export and import everything” either has an app based route they have not explained, or has not thought the job through. Ask which mechanism they use and what the per order limits are. Then decide how much history you need: full history supports customer service and lifetime value reporting, but many merchants move three years and archive the rest. Settle that before you get a quote, because order volume drives price on every per record tool here.

Will A Generic Importer Do The Job?

It can, with a lot of manual work. Matrixify is the obvious candidate and a capable Excel and CSV importer, but it names Magento, BigCommerce, Lightspeed, WooCommerce, WordPress and Shopify as sources, not Shift4Shop. Using it means exporting from Shift4Shop and hand mapping every column into the Shopify schema yourself, viable for a small catalog and painful for a large one. And the absence of a Shift4Shop page is the normal state of this market rather than a mark against any firm. It just means the mapping work lands on you. To widen the search, our list of top Shopify web design agencies covers the build side, and the Shift4Shop experts and development agencies roundup covers teams that know the source platform.

What Will Shopify Cost You After The Move?

Budget the destination, not just the move. As published in September 2026, Shopify Basic is $39 per month billed monthly or $29 annually, Grow is $105 or $79, Advanced is $399 or $299, and Plus starts from $2,300 per month on a three year term. Card rates are 2.9 percent plus 30 cents on Basic, 2.7 on Grow and 2.5 on Advanced, with Shopify Payments available in 40 countries and regions. One line item catches Shift4Shop merchants off guard: Shopify charges a per transaction fee for using a third party gateway instead of Shopify Payments, at 2 percent on Basic, 1 percent on Grow, 0.6 percent on Advanced and 0.2 percent on Plus. Shift4Shop has no equivalent penalty on any tier. If you are locked into a processor, model that against annual volume first, and if the math looks bad, review the Shift4Shop alternatives before fixing the destination.

Conclusion

The absence of an official Shopify path for Shift4Shop is not a reason to stay, but it is a reason to be deliberate. Every provider here is a third party filling a gap Shopify chose not to fill, and quality varies enormously between a $59 automated run and a $20,000 agency rebuild.

The sequence is straightforward. Decide first how much of the storefront you are rebuilding, because that decision splits the market into tools and agencies and a roughly hundredfold price range. Then inventory the long tail honestly, the blogs, the reviews, the coupons, the outstanding gift certificates, and strike off anyone who does not document moving them. Then settle redirects and order history in writing, with a named owner and date.

Run a demo migration wherever one is offered, and check the awkward records rather than the clean ones: the product with fifty variants, the customer with a store credit, the order with a partial refund. What survives that will survive launch. To compare vendors more broadly, the REVERB company directory is a reasonable next stop.
