Are you unsure what your plan will cost from here?
The official site now lists one End-to-End plan with a stated monthly platform fee, while third-party guides written earlier describe separate tiers and a free option. The site also says a monthly fee may depend on plan and processing volume.
Check your own account and any written terms, since older articles may be out of date. Compare the total with payment fees and apps included, not the headline fee alone.
Do you want more freedom over how you take payments?
The official plan page says card payments are set up through integrated processing and that processor fees apply. Reviews describe the lowest platform fee as linked to using the platform's own payments, and details differ between sources.
If you use a particular processor or gateway, confirm what your plan allows and costs. Shopify supports its own payments and other gateways, but fees and availability vary by country.
Does support feel slower or less helpful than you need?
Some reviewers say support has declined or is hard to reach, while the official site promotes round-the-clock support. Experiences vary.
Think about how often you need help and how urgent it is. Keep a record of open issues before you move so nothing is lost.
Do your store design options feel limited or dated?
Reviewers describe the themes as less modern than some alternatives and say getting the most from customization can require some HTML knowledge.
The official site lists a library of free themes. If design polish matters to you, view several themes on each platform and see what changes need a developer.
Is the admin hard to learn or confusing for your team?
Reviewers describe setup, apps and the dual editing tools as confusing, especially for newcomers, although others value how much is built in.
Ask your staff which tasks they find hardest. A simpler admin can matter more than a longer feature list if several people use it daily.
Do you need apps and integrations the platform lacks?
Merchants and reviewers note that Shift4Shop leans on built-in features, such as a blog and CRM, while Shopify has the larger third-party app market. Some who moved say specific channel apps still had rough edges.
List the integrations you depend on, then check each has a Shopify equivalent. Some may cost more or work differently, and a few may not have a match.
Is your business based where the platform is fully available?
The official plan page states that store access is unavailable in some countries and regions, and reviews connect the lowest-cost offer to certain locations.
If you sell from or plan to expand to other regions, confirm availability and payment support. Shopify's availability is also country-specific, so we check this in the review.

Pet supplies
Advance Pet Mart started on WooCommerce, but plugin and hosting problems kept getting in the way. We moved the store to Shopify, and they are very happy with the move. We also worked with them on design, SEO, AI SEO and marketing.

Electronics & gaming retail
We moved City of Games from a broken OpenCart store to Shopify in four weeks, kept its look, rebuilt the features it had lost and protected its search rankings with 301 redirects.

Where each item goes in Shopify, and what we check before launch.
| Shift4Shop / 3dcart | Where it goes in Shopify | What we check |
|---|---|---|
| Products, SKUs, descriptions & media | Products, variants, media and suitable custom fields. | Available values, matching identifiers and whether every image can be accessed. |
| Regular options & Advanced Options | Agreed variants, options or custom configuration. | Combinations, option part numbers, price adjustments, stock and weight behavior. |
| Bulk pricing | Volume pricing, discounts or an app, depending on the rules and plan. | Quantity breaks against real order examples. |
| Categories & brands | Collections, menus, vendor information or pages. | Membership, hierarchy and the browsing journey customers actually use. |
| Inventory | Shopify inventory, updated again just before launch. | Product- and option-level quantities and the agreed stock source. |
| Shift4Shop / 3dcart | Where it goes in Shopify | What we check |
|---|---|---|
| Customers & addresses | Customer records and supported fields. | Duplicates, address formatting, export filters and marketing consent where it is available. We don’t assume everyone opted in. |
| Customer groups & price levels | The agreed access and pricing setup: B2B catalogs, an app or another scoped approach. | Group membership, prices and restricted products. Customer tags alone don’t create a pricing system. |
| Customer sign-in | A Shopify customer-account setup that suits your customers. | Passwords don’t transfer. Shopify accounts can sign in with an emailed one-time code; we plan the customer message. |
| Historical orders & line items | Agreed history, imported with a suitable method. | Dates, totals, line items, customer matching and supported statuses. Old payments and refunds are not recreated. |
| Product reviews & questions | A compatible review app, after assessment. | Export availability, product matching and who owns the review data. |
| Shift4Shop / 3dcart | Where it goes in Shopify | What we check |
|---|---|---|
| Recurring orders & subscriptions | A compatible subscription app and an agreed continuity plan. | Billing provider support, customer consent, schedules and saved payment methods, before anything is promised. |
| Reward points | A loyalty app, a reconciled balance or an agreed reference. | Point balances, earning rules and how customers are told about the change. |
| Gift certificates & store credit | Shopify gift cards, store credit or another agreed method. | Outstanding balances, codes and redemption, reconciled before and after launch. |
| Open returns | Finished on the old store or handled under an agreed process. | Which returns are still in progress at cutover and where refunds happen. |
| Shift4Shop / 3dcart | Where it goes in Shopify | What we check |
|---|---|---|
| Content pages, blog posts & files | Shopify pages, blog articles and files within scope. | Formatting, media links and files that still load from the old store. |
| Custom URLs, metadata & existing redirects | Agreed metadata, an old-to-new URL map and tested redirects. | Important old paths, older 3dcart-era links, redirect chains and exceptions. |
| Store design & template | A Shopify theme: new, customized or a recreated version of your look. | Mobile layouts, navigation and editable sections. The Shift4Shop template doesn’t install on Shopify. |
| Payments, shipping & tax | Supported payment providers, shipping rules and the tax settings you approve. | Eligibility, special shipping rules and test checkouts. |
| Marketing, inventory & fulfillment tools | Supported connectors, or integration work scoped separately. | Which way data flows, product identifiers and imports that could trigger emails. |
Existing passwords, live card credentials and records your store can’t export are not assumed to transfer. Each one gets an explicit decision in your proposal.

FreeStore review and quote before you hire us
60 daysPost-launch migration support included
Send us your store URL and the features you need to keep. We look at your catalog, options, built-in tools, integrations and important URLs, then explain what moves, what needs a replacement and what the project will cost.
No exports needed to start. We tell you what we need and arrange secure access later.
Not every feature is switched on in every Shift4Shop store, and few have an identical native Shopify equivalent. We plan the ones you use, with any monthly app costs, before you approve the scope.
We don’t promise automatic savings. You see both sides before you decide.
Your Shift4 processing setup doesn’t automatically become a Shopify payment setup. We check:
Live credentials and stored payment methods aren’t ordinary export fields. We can’t guarantee the same provider or rates on Shopify.
Internal catalog references are not the same as your SKUs or option part numbers. We use the right key to match each record.
We find which options control stock, weight, price or personalization, then agree how each should work in Shopify.
Image and gallery references, categories, pages and linked files, including any that still load from the old store.
We reconcile agreed counts and compare representative products, combinations and final prices with the old store before you approve.
An export alone doesn’t give you:
So for each one we agree what is:
We review:
Retail-only store? This part may not apply. We review it only if you use it.
A data import doesn’t reconnect campaigns on its own, so we check each agreed connection.
We don’t send old links to the homepage. Rankings, traffic and ad performance can change after a migration; we reduce the avoidable risks, and nobody can honestly guarantee unchanged results.
Example mapping. We inventory your store’s actual paths; links with query strings are tested individually.
Registrar access and DNS records need their own plan, so your domain connects to Shopify and the right services keep working.
Shopify doesn’t host email mailboxes, and a storefront migration doesn’t move mailbox history. Email stays where it is or moves under a separate plan.
Keep the source store available until the agreed data, final-order and dependency checks are complete.
Moving the website doesn’t automatically end your store, domain, payment or other agreements. You decide when to cancel each one under its own terms; we tell you what still depends on it.

| Your question | Self-service migration tool | Migration managed by WEP |
|---|---|---|
| Who defines the scope? | You choose the records and options the tool supports. | We review your store and document what moves, what is replaced and who does what. |
| What happens to built-in features? | Replacing reviews, rewards, price levels or subscriptions is usually a separate job. | We plan a Shopify feature, app or custom work for each feature you use. |
| How are Advanced Options handled? | Mapped to the structure the tool supports, then checked by your team. | We agree the Shopify setup and test combinations, final prices, stock and order lines. |
| Who builds the storefront? | You, a theme, or another developer. | Our team: a new theme, a customized theme or a recreated version of your look. |
| Who runs the launch? | Your team coordinates the final updates, domain and checks. | We run the pre-launch update, domain connection, redirects, catch-up checks and 60 days of support. |
The online store migration was seamless without having 0 downtime. The staff is properly trained, well communicated and proactive Highly recommended
Web commerce pros created a really lovely design for our website. They also changed the layout for our images and updated/resized images so that the site is overall much more attractive. We have been receiving a lot of positive feedback from customers on the ease of use and the overall look of our site. In addition, we are very grateful to Roy for coming up with a creative solution for allowing customers to easily create their own quotes, which has been very helpful to both our operations and our customers.
Arfat and team were proficient with BigCommerce Page Builder and Shogun to create and modify pages. We successfully completed the migration with their assistance and were happy with their work. We would hire again soon for our next project.

Costs outside our migration fee, so nothing comes as a surprise.
Your Shift4Shop store keeps selling throughout. Orders and customers move in stages: an initial migration, a pre-launch update, a coordinated launch and a catch-up check for any order that still reached Shift4Shop around the switch. We agree a catalog freeze or change log for the build period, and prices and stock follow the agreed synchronization plan.
We found no shutdown announcement, and the platform is still sold with an official plan page. Plans and terms do change, so check your own account and ask us if you want a view on options.
It varies with catalog size, order history, design scope and integrations. We give a realistic timeline after the free store review instead of a fixed number.
Keep admin access to your store, domain and payment accounts. Run exports of products, customers and orders, and list apps, feeds and custom code you use. We guide you through the rest.
Shift4Shop's help center describes CSV exports for orders, and its backup article says most store data can be exported as CSV, including customers. Exact menu steps can change, so we confirm them during the free store review.
Shopify says historical orders need a migration app or API rather than a plain CSV import. Order statuses do not map one to one, so we plan how to represent them. How complete the history is depends on the export.
Products and categories usually can, though options may need reshaping to fit Shopify variants. Reviews, blog posts and pages can move with the right tools but are not automatic. We list what moves in the review.
Standard CSV exports are described in the help center and backup articles. A webmaster page also lists paid custom and scheduled export services, so check which you need. We tell you if your case needs anything special.
Customer records can be imported, but passwords are generally not carried across in plain exports, and the sources we found do not say they are. Plan for customers to set a new password, and we confirm the options for your store.
Groups and pricing levels do not map directly. We turn them into Shopify customer tags or segments where that fits, and flag anything that needs another approach.
The official plan page says domain registration is included, so check where your domain is registered. You can usually keep it and point it to the new store. We help with the DNS change at launch.
No. The storefront is rebuilt on a Shopify theme, so we match your branding or refresh the design. Custom code and built-in features such as a blog or CRM need a plan for replacement.
Shopify URL patterns differ, so we create 301 redirects from old product, category and page URLs before launch and check them after. Rankings can shift for a while after any migration, and we cannot promise they will not.
We build and test the new store while the old one stays live, then schedule the switch for a quiet time. A brief interruption at the domain change is possible and we do not promise zero downtime.
It may. Shift4Shop's platform pricing and payment terms are tied to its payment setup, so check your contract. Shopify supports its own payments and other gateways, with fees depending on country and plan. We map this in the review.
The cost depends on catalog size, orders, design scope and integrations. We give a clear quote after the free store review, before any work starts.
60 days of support for migration issues within the agreed scope: we fix migration problems, reconcile late orders and check redirects. New development, unrelated issues and ongoing marketing or maintenance are scoped separately.
Share your store URL and the features you need to keep. We’ll review it for free and talk through the data, the Shopify build and the ongoing setup before you commit.
