2026 migration cost guide
What a Shopify Plus migration costs
Most Shopify Plus migrations cost $25,000–$250,000+. WooCommerce and BigCommerce stores sit at the low end and take 3–12 weeks; Magento, Adobe Commerce and Salesforce Commerce Cloud stores with B2B, ERP integrations and custom checkout logic sit at the high end and take 8–24+ weeks. The ranges are OUXP’s own, from the migrations we run off all five platforms – and complexity, not catalog size, decides where your store lands.
The short answer
A Shopify Plus migration is a one-time engineering project: products, customers and order history moved, the storefront and checkout logic rebuilt, integrations reconnected and every URL redirected to protect search rankings. Shopify charges no migration fee – what you pay for is that work.

Fixed in writing before work starts
Where your store lands inside its band depends on six factors, explained below. If you’d rather skip the reading, a free migration assessment places your store in a band within 2 business days – no store access needed.
How much does each migration path cost?
These are the typical ranges for OUXP migrations, by the platform you’re leaving. The timeline runs from kickoff to launch; the price covers the migration project, not the Shopify Plus subscription or apps.
| From | Typical range | Typical timeline | What drives the cost |
|---|---|---|---|
| WooCommerce | $25,000–$60,000 | 3–10 weeks | A clean data export; mapping plugins to Shopify apps is the main work |
| BigCommerce | $30,000–$70,000 | 4–12 weeks | SaaS to SaaS, the most direct path; options and modifiers need restructuring |
| Magento 1 or 2 | $50,000–$180,000 | 8–24+ weeks | Option matrices, attribute mapping, custom modules and URL restructuring |
| Adobe Commerce | $60,000–$200,000 | 10–24+ weeks | Everything a Magento move involves, plus Adobe’s B2B module and enterprise integrations |
| Salesforce Commerce Cloud | $80,000–$250,000+ | 10–24+ weeks | Heavy custom business logic, multi-site builds and integrator-built customizations |
Typical bands, not quotes, as of October 2026. Bars show each range on one scale from $0 to $250,000+.
Where your store lands inside its range
The bands are wide because stores on the same platform differ so much. This is what typically puts a store at either end.
| Platform | Lower end | Upper end |
|---|---|---|
| WooCommerce | Plugins with direct Shopify app equivalents, a clean product export, one store, the current design recreated | Custom plugin code or APIs to rebuild, subscription and loyalty data to move, ERP or CRM connections, a redesign |
| BigCommerce | A catalog whose options fit Shopify’s 3-option model, a standard app stack, one storefront | Options and modifiers to restructure, B2B Edition workflows, checkout customizations, ERP integration, a redesign |
| Magento 1 or 2 | One store, a catalog that fits Shopify’s product model and a common extension stack: 8–12 weeks | Multi-store builds, heavy custom modules and complex Shopify Functions logic: 18–24+ weeks. B2B accounts, ERP integration, option matrices to restructure or checkout customization sit between, at 12–18 weeks |
| Adobe Commerce | A single site whose catalog fits Shopify’s product model, with standard B2B or none | B2B quote and approval workflows, ERP and PIM integrations, several websites or store views, Adobe services such as Live Search to replace |
| Salesforce Commerce Cloud | A single site whose catalog fits Shopify’s product model | Multi-site realms across markets, heavy custom cartridge logic, Salesforce CRM, Marketing Cloud or Order Management connections to keep |
Each migration page goes deeper on its platform – what moves, what gets rebuilt and how the timeline breaks down:
What moves the price? Six cost drivers
Catalog size is rarely what separates a $50,000 Magento migration from a $180,000 one. These six factors do – and we scope each one before quoting, so the number holds once work starts.
-
Product model and option complexity
Biggest driver on Magento
Shopify allows up to 2,048 variants per product but only three options – size, color and material, say. Products with more options, or very large option matrices, need a new product model before any data moves: separate products shown together as one listing, filter-only attributes moved to metafields, rarely sold combinations retired against real order history. On Magento projects this is the single biggest scope driver.
-
Custom checkout and promotion logic
Rebuilt, never ported
Checkout code doesn’t port – it’s rebuilt. On Shopify, custom cart, discount, shipping and payment rules run as Shopify Functions, and checkout changes as checkout UI extensions; the older tools some guides still mention, checkout.liquid and Shopify Scripts, are retired (Scripts stopped running on June 30, 2026). Each custom rule is its own piece of work: a few standard promotions cost little, years of layered rules cost a lot.
-
Integrations
Priced per connection
Each ERP, PIM, OMS or 3PL connection is its own mini-project: map the data, decide what syncs in which direction and how often, handle errors and test with real orders. A ready-made connector app costs least; middleware such as Celigo or Boomi, or custom Admin API middleware for unusual flows, costs more. See commerce integrations for how we build them.
-
B2B requirements
Standard B2B is native
Since April 2, 2026, Shopify’s core B2B runs on every paid plan: company accounts, up to 3 B2B catalogs, volume pricing, net payment terms and quotes through draft orders. A standard wholesale program maps onto those native features. Cost comes from what goes beyond them – Shopify Plus-only needs such as more than 3 catalogs, catalogs assigned to specific companies, deposits or partial payments; custom approval chains that need a light rebuild; and price lists synced with an ERP.
-
Design scope
Fully in your control
Your current theme can’t run on Shopify, so the storefront is always rebuilt as a Shopify theme. Recreating the current design is the cheapest option; refreshing it during the rebuild costs more; a full redesign adds a design phase before development starts. Decide this early – it’s one of the few drivers fully under your control.
-
Data volume and hygiene
Condition beats size
Size matters less than state. A large, clean catalog moves faster than a small, messy one: duplicate customer records, inconsistent attribute values, products without SKUs and broken image links each need a rule to clean, map or retire them. Every pilot import is then reconciled against the source – counts, totals and links – before the full run.
Not sure which of these apply to your store? The free migration assessment flags the 2–3 most likely to move your price.
What should a migration quote include?
Most budget surprises come from a quote that leaves out work you assumed was in it. Ask any agency which of these two lists each item falls in – that question alone prevents most of them.
Included in a complete quote
- Data migration – products, customers, order history and content – with a reconciliation report
- The product model and attribute mapping, approved before data moves
- A URL map with 301 redirects for every URL pattern
- SEO metadata, canonicals and structured data carried over
- A theme build that recreates your design, or the design scope you agreed
- App mapping and configuration to replace your extensions or plugins
- QA and a rehearsed cutover
- A post-launch monitoring window for orders, errors and rankings
Commonly priced separately
- A full redesign, beyond recreating or refreshing your design
- Net-new custom features your store doesn’t have today
- ERP middleware development
- Ongoing support after the monitoring window
- Paid app subscriptions, billed by each vendor
- Photography and new content
At OUXP, SEO preservation – the URL map, 301s, metadata, structured data and post-launch monitoring – is part of every migration, never an add-on.
What else should you budget for?
The migration is paid once. These costs sit outside any migration quote, and most of them continue for as long as you run the store.
| Cost | What to expect |
|---|---|
| Shopify Plus subscription | Billed by Shopify: from $2,300/month on a three-year term or $2,500/month on a one-year term – roughly $27,600–$30,000 a year |
| High-volume platform fee | Large merchants move to a revenue-based variable fee. Shopify doesn’t publish the rate; about 0.35–0.40% of sales above roughly $800,000 a month is commonly reported – confirm yours in writing with Shopify |
| App subscriptions | Billed by each app’s vendor. The total depends on your stack, and many apps replace extension or plugin licenses you already pay for |
| Payment processing | Applies on every platform. A gateway other than Shopify Payments adds a Shopify transaction fee, currently reported at 0.20%, on top of the processor’s own fees |
| Your current platform until launch | License, hosting and maintenance continue until cutover – launch before your renewal date so you don’t pay for both |
| Support after launch | Optional – your own team or an agency. OUXP retainers start at $2,500/month |
Shopify Plus pricing checked on Shopify’s pricing page in October 2026. The high-volume rate is an industry report, not a published price.
All in – subscription, apps and ongoing development, before payment processing – a realistic Shopify Plus budget lands between $60,000 and $250,000+ a year. The Shopify Plus pricing guide breaks that down by store size.
How do you avoid overpaying?
Overpaying rarely means accepting a high quote. It usually means a low quote that grows mid-project, or paying for two platforms while a migration runs late.
- Get the scope in writing before the price. A fixed quote after discovery holds; an open-ended hourly estimate grows with every surprise found mid-build.
- Compare quotes line by line, not by the total. Check each one against the two lists above.
- Ask how variants and attributes will be restructured. A vague answer means it hasn’t been scoped – and on Magento it’s the biggest driver of all.
- Confirm SEO preservation is in the price. The URL map, 301s, metadata and post-launch monitoring should never be an upsell.
- Be wary of quotes far below these ranges. They usually leave out data migration or SEO work, which comes back as change orders halfway through.
- Retire before you rebuild. Unused extensions, expired promotion rules and features nobody uses still cost money to rebuild; discovery is the time to drop them.
- Time the move against your renewal. Start enterprise migrations 6–9 months before a license or hosting renewal, and launch away from peak season, so you never pay for both platforms.
What does OUXP charge?
Migrations start at $25,000 for a straightforward WooCommerce replatform and $50,000 for a standard Magento project; the cost table above gives the typical band for every platform. Every migration gets a fixed price and timeline in writing before work starts, and SEO preservation is always included.

Price, timeline and milestones in writing. Anything outside the agreed scope is priced with you before it’s built.
Honest note: sometimes the right budget is zero
If your platform costs don’t yet outweigh the cost of moving, or a contract renewal makes waiting the smarter choice, the assessment says so in writing. And a store selling under roughly $1M–$2M a year with a simple catalog may be better served by a standard Shopify plan than by Plus – the pricing guide explains when standard Shopify is enough, and our platform comparison guides cover when staying on your current platform makes sense.
Migration cost questions
Short answers to what buyers ask us most. Something else? Ask an engineer – first response within 30–60 minutes in business hours.
Why do migration quotes vary so much between agencies?
Usually scope, not hourly rate. One quote includes data migration with reconciliation, the 301 map, SEO carryover, QA and a rehearsed cutover; another prices a theme build and treats the rest as change orders. Before comparing totals, check every quote against the same list: data, product model, URLs and SEO, apps, integrations, checkout logic, QA, cutover and post-launch monitoring.
Is a cheaper migration ever the right choice?
Yes. A small WooCommerce or BigCommerce store with a clean catalog, standard apps and no ERP genuinely belongs at the low end – $25,000–$70,000 over 3–12 weeks. The risk is paying low-end prices for enterprise-complexity work: a quote that ignores option matrices, custom checkout rules or integrations doesn’t remove that work, it moves it into change orders halfway through the project.
Does a bigger catalog mean a higher migration price?
Not by itself. A large catalog of simple, well-structured products imports in bulk and costs little more than a small one. Cost comes from structure: products with more than Shopify’s 3 options, attributes that need metafields or metaobjects, duplicate or inconsistent data, and custom fields in years of order history. Timeline and price track that complexity, not the SKU count.
How can we lower the migration price?
Reduce what has to be rebuilt. During discovery, retire the extensions, promotion rules and features nobody uses. Clean your data first – duplicate customers, products without SKUs and broken image links each need a rule. Recreate your current design and leave a redesign until after launch, and supply new content and photography yourself. Don’t cut data reconciliation, the 301 map or the rehearsed cutover: skipping them moves the cost into lost orders and rankings.
Does the migration price include Shopify Plus and apps?
No. The migration is a one-time project fee. Shopify bills the Plus subscription – from $2,300/month on a three-year term or $2,500/month on a one-year term, as of October 2026 – and each app vendor bills its own subscription. Shopify charges no migration fee. Budget for your current platform until launch, too, and time the cutover before your renewal so you don’t pay for both.
Can we migrate in phases to spread the cost?
Yes, if you run several sites, brands or markets. One store or region moves first as the pilot, and the rest follow on the same foundation – the theme, apps, integrations and data mappings are built once and reused – which spreads cost and risk across several launches. A single store usually moves in one rehearsed cutover, which is simpler than running two platforms side by side.
What does OUXP charge for a migration and for support after it?
Migrations start at $25,000 for a straightforward WooCommerce replatform and $50,000 for a standard Magento project. Typical bands are $30,000–$70,000 from BigCommerce, $60,000–$200,000 from Adobe Commerce and $80,000–$250,000+ from Salesforce Commerce Cloud. Every price is fixed in writing before work starts, after the free assessment and a deeper scoping review. After launch, retainers cost $2,500, $5,000 or $9,500 a month, and one-time emergency support is $250/hour with a 2-hour minimum.
