Key Takeaways
- Audit your active SKU count before requesting quotes — catalog size alone determines whether your migration costs $3,000 or $350,000+.
- Budget at least $5,000 for SEO preservation to avoid losing 20–50% of organic traffic from broken 301 redirects post-launch.
- Reserve 15–20% of your base migration quote — on a $50,000 project that means $7,500–$10,000 — for post-launch bug fixes and data cleanup.
Shopify migration costs range from $3,000 to $350,000+ depending on catalog size, integration depth, and the technical debt on your current platform. For stores generating $250K+/month, the realistic investment sits between $30,000 and $85,000 for the migration itself — with Year 1 total costs often reaching $50,000 to $120,000. If someone quoted you $5,000 for a full mid-market migration, that number should concern you. Four specific variables — catalog size, origin platform, custom functionality, and integration depth — drive the majority of cost differences, and understanding each one before you request a quote is the difference between a clean launch and an expensive remediation project.
Shopify Migration Cost: What Actually Drives the Price (2026 Breakdown)
Shopify migration costs range from $3,000 to $350,000+ depending on catalog size, integration depth, and the technical debt on your current platform. For stores generating $250K+/month, the realistic investment sits between $30,000 and $85,000 for the migration itself — with Year 1 total costs (platform fees, apps, retainer) often reaching $50,000 to $120,000 [6].
If someone quoted you $5,000 for a full mid-market migration, that number should concern you. Here’s why — and what the real cost drivers look like.

Key Takeaways
- Catalog size is the single biggest cost driver. Under 500 SKUs: $3,000–$15,000. Over 5,000 SKUs with ERP: $80,000–$350,000+ [1].
- DIY migrations cost $300–$1,000 upfront but frequently cause 20–50% organic traffic loss from broken redirects [2].
- SEO preservation alone costs $5,000–$20,000 and is non-negotiable for stores with meaningful organic revenue [1].
- Budget 15–20% on top of your migration quote for post-launch bug fixes and data cleanup [3].
- Year 1 total cost of ownership for a mid-market brand: $50,000–$120,000 [6].

What Does a Shopify Migration Actually Cost?
Shopify migration costs in 2026 follow a tiered model based on store complexity — not a flat rate. The days of fixed-price migration quotes are largely gone. Agencies now price by catalog size, origin platform, custom functionality requirements, and integration depth.
Here is the current benchmark by store profile:
| Store Profile | SKUs / Complexity | Migration Cost | Timeline |
|---|---|---|---|
| Small Store | <500 SKUs; basic theme | $3,000–$15,000 | 2–4 weeks |
| Mid-Market | 500–5,000 SKUs; custom theme | $15,000–$75,000 | 4–8 weeks |
| Mid-Market (B2B / Multi-Region) | 1,000–10,000 SKUs | $30,000–$80,000 | 6–12 weeks |
| Enterprise (Shopify Plus) | 5,000+ SKUs; ERP/3PL; custom checkout | $80,000–$350,000+ | 8–24 weeks |
| Headless (React / Next.js add-on) | Custom backend + Shopify | +$20,000–$60,000 | +4–8 weeks |
Shopify migration costs range from $3,000 for small stores to $350,000+ for enterprise builds. For mid-market stores doing $250K+/month, the standard investment is $30,000–$85,000 for the migration, plus $50,000–$120,000 in Year 1 total costs including apps and retainer [6].

What Makes a Migration More Expensive?
Price variance is not arbitrary. Four technical variables drive the majority of cost differences across projects.
1. Catalog Size and Data Complexity
This is the primary lever. A WooCommerce store with fewer than 500 products can migrate for $500–$2,000 using app-based tools. An enterprise multi-brand architecture with product variants, custom attributes, and historical order data can reach $80,000–$250,000+ [1].
The cost is not just moving SKUs — it is cleaning, mapping, and validating every data record so nothing breaks post-launch. Customer order history, variant logic, and product metadata all require manual QA at scale.
2. Origin Platform Technical Debt
Where you are migrating FROM matters as much as where you are going. Platforms with rigid data structures or heavy plugin dependencies create significant cleanup work.
| Origin Platform | Typical Migration Cost |
|---|---|
| Squarespace / Wix | $2,000–$8,000 |
| WooCommerce / BigCommerce (500–5,000 products) | $8,000–$30,000 |
| Magento | $25,000–$100,000 |
| Custom / ERP Backends | $100,000–$1,000,000+ |
Source: [2]
Magento migrations consistently run at the high end because of complex data structures, custom modules, and legacy code that does not translate directly to Shopify’s architecture. Every custom function on the old platform needs to be rebuilt, replaced, or removed.
3. Custom Functionality Requirements
Loyalty logic, complex B2B pricing tiers, multi-currency configurations, subscription flows — none of these come standard on Shopify. If your current platform has custom-built features, those need to be scoped, developed, and tested on Shopify from scratch.
This is where budgets expand fastest. A single custom feature (say, a tiered wholesale pricing engine) can add $10,000–$30,000 to a migration scope. For stores with multiple custom features, costs compound quickly.
4. Integration Depth (ERP, 3PL, CRM)
Connecting Shopify to an ERP like NetSuite or a 3PL like ShipBob requires custom API work. For enterprise stores, this alone can represent 30–40% of total migration cost. Multi-region builds with separate storefronts, localized pricing, and cross-border tax logic add another layer of complexity.
App migration adds $2,000–$10,000 on top — because legacy WooCommerce or Magento plugins do not have direct Shopify equivalents, and finding, configuring, and testing replacements takes real time [1].
The four primary cost drivers are catalog size, origin platform technical debt, custom functionality requirements, and integration depth (ERP/3PL/CRM). Each variable can add $10,000–$100,000+ to a migration scope. Magento migrations, for example, typically run $25,000–$100,000 due to complex data structures [2].

The Hidden Costs Most Operators Miss
The quoted migration fee is not the total cost. Three line items consistently catch operators off guard.
SEO preservation: $5,000–$20,000. This is the most under-budgeted item in any migration. Proper URL mapping and 301 redirect implementation protect your organic traffic. Skip it or underfund it, and you risk losing 20–50% of organic traffic — a number that translates directly to lost revenue at your scale [1][2].
For a store doing $300K/month with 40% of traffic from organic search, a 30% traffic drop is $36,000/month in lost revenue. The $10,000 SEO preservation budget pays for itself in the first week.
Post-launch fixes: 15–20% of base quote. Budget this as a line item, not a contingency. Data cleanup, broken integrations, and display errors are standard post-launch realities — not edge cases [3]. On a $50,000 migration, that is $7,500–$10,000 in expected follow-on work.
Staff training: $3,000–$8,000. Your team needs to operate the new platform. Shopify’s admin differs enough from Magento or WooCommerce that onboarding costs real time and money [1].
Hidden migration costs include SEO preservation ($5,000–$20,000), post-launch bug fixes (15–20% of base quote), app replacement ($2,000–$10,000), and staff training ($3,000–$8,000). These items routinely add 25–35% to the initial migration quote [1][3].
—
Is DIY Migration Cheaper Than an Agency?
Short answer: upfront, yes. In total cost of ownership, almost never.
DIY or app-based migrations (tools like Cart2Cart or LitExtension) cost $300–$1,000. They move product data and basic customer records. They do not handle SEO redirect mapping, custom functionality, theme development, or integration testing.
The result: broken redirects, missing metadata, and a storefront that does not match your brand. The organic traffic loss from improper redirect handling alone — documented at 20–50% — makes DIY migration a false economy for any store with meaningful search traffic [2].
A specialist agency running a full mid-market migration costs $15,000–$50,000 for 500–5,000 SKUs [1][4]. That investment includes SEO preservation, QA testing, custom theme work, and a launch that does not crater your rankings.
For stores at $250K+/month, a migration quote under $25,000 is almost certainly a partial migration — one that will require significant cleanup investment post-launch [6].
DIY migrations cost $300–$1,000 but risk 20–50% organic traffic loss from broken redirects [2]. For stores doing $250K+/month, a specialist agency migration ($15,000–$75,000) consistently delivers better total cost of ownership than a partial DIY migration that requires expensive post-launch remediation.

Quick Wins: What to Do Before You Get a Quote
1. Audit your current catalog (Easy) Count your active SKUs, variants, and custom attributes. This single number will determine your tier. Expect a $500 difference in quote for every 500 additional SKUs at the mid-market level.
2. Document every custom feature (Medium) List every piece of functionality your current platform has that is not native to a standard Shopify theme. Each item on that list is a development line item. Knowing the list before you talk to an agency prevents scope surprises.
3. Pull your organic traffic breakdown (Easy) Use GA4 to identify what percentage of your revenue comes from organic search. This number determines how much SEO preservation budget you need. If organic drives 30%+ of revenue, budget at the high end of the $5,000–$20,000 SEO range.
4. Map your integrations (Medium) List every third-party system connected to your current store: ERP, 3PL, CRM, loyalty platform, subscription tool. Each integration requires scoping. Knowing this list upfront shortens your agency discovery process and prevents mid-project surprises.
5. Plan for Year 1 total cost, not just migration cost (Easy) For a $250K+/month brand, budget $50,000–$120,000 for Year 1 total: migration fee + Shopify Plus subscription ($2,300/month) + apps + post-launch retainer [6]. Cash flow planning at this level prevents rushed decisions that compromise the migration quality.

FAQ
How much does a Shopify migration cost? Shopify migration costs range from $3,000 for small stores (under 500 SKUs) to $350,000+ for enterprise builds with ERP integrations and custom checkout logic. For mid-market stores doing $250K+/month, the realistic investment is $30,000–$85,000 for the migration itself, with Year 1 total costs reaching $50,000–$120,000 [6].
What makes a Shopify migration more expensive? Four variables drive cost: catalog size (SKU count and data complexity), origin platform technical debt (Magento migrations run $25,000–$100,000 vs. $2,000–$8,000 for Wix), custom functionality requirements (loyalty logic, B2B pricing tiers), and integration depth (ERP, 3PL, CRM connections). Each variable can add $10,000–$100,000+ to the scope [1][2].
Is DIY migration cheaper than hiring an agency? DIY migration tools cost $300–$1,000 upfront but routinely cause 20–50% organic traffic loss from broken redirects and missing SEO implementation [2]. For stores with significant organic revenue, this loss far exceeds the cost of a professional migration. Specialist agency migrations ($15,000–$75,000 for mid-market) deliver better total cost of ownership.
What hidden costs should I budget for? Budget for SEO preservation ($5,000–$20,000), post-launch bug fixes (15–20% of base quote), app replacement ($2,000–$10,000), and staff training ($3,000–$8,000). These items typically add 25–35% to the initial migration quote and are non-negotiable for a clean launch [1][3].
Should I consider a headless Shopify build? Only if your current architecture strictly requires it. Headless builds add $20,000–$60,000 in development costs and 4–8 weeks to the timeline [4]. For most mid-market stores, standard Shopify Plus delivers the performance and flexibility needed without the additional complexity.

Our team of 40+ specialists has scoped and supported migrations across every major platform — from WooCommerce and Magento to custom ERP-backed builds — giving us benchmark data on real migration costs that generic agency quotes rarely reflect.
Our Methodology: Leaky Bucket Framework
Every migration has hidden leaks — broken redirects, missing metadata, untested integrations — that drain revenue before you even notice. The Leaky Bucket Framework identifies and seals each leak before launch, ensuring your migration investment compounds rather than erodes.
"The single most under-budgeted line item we see in migration scopes is SEO preservation — stores skip the $10,000 investment and then spend $36,000 a month recovering lost organic revenue. At BGS, across 2,654+ stores optimized and $550M+ in tracked revenue, improper redirect handling is the number-one cause of post-migration revenue decline." — Build Grow Scale Revenue Optimization Team
