Migrate, optimize and scale on Shopify Plus
OUXP is a Shopify Plus agency for enterprise and fast-growing brands leaving Magento, Adobe Commerce, Salesforce Commerce Cloud, BigCommerce or WooCommerce, and for Shopify Plus stores that need senior engineers. We migrate the store with data, URLs and SEO mapped first, then keep optimizing and supporting it month to month with AI-accelerated, senior-reviewed engineering – and a 24/7 emergency line for when something breaks.

What do you need help with?
A one-off migration, a hard feature, faster pages or a team on call every month – six ways brands work with us, each run by senior engineers.
-
Migrations to Shopify Plus
From Magento, Adobe Commerce, Salesforce Commerce Cloud, BigCommerce or WooCommerce. Data, URLs, integrations and SEO are mapped before anything moves, and the cutover is rehearsed.
-
Shopify Plus engineering
For stores that have outgrown their theme: custom checkout and discount logic (Shopify Functions, Checkout UI extensions), custom apps, headless storefronts and ERP or CRM integrations.
-
Performance & CRO
Fast pages, products that explain themselves and nothing in the way of checkout: Core Web Vitals and technical SEO work, conversion research, A/B tests shipped as production code, and theme customization from $500.
-
AI commerce solutions
Practical AI for customer support, catalog enrichment, merchandising and internal tools – scoped to the manual work it actually removes from your team’s week.
-
Retainers & dedicated engineers
Monthly plans from $2,500 (20 hours) to $9,500 (90 hours or a dedicated engineer). Unused hours roll over one month, and the top tier includes 24/7 emergency cover.
-
Emergency support
Store down, checkout failing or an integration stopped syncing? Call the 24/7 line. One-time help is $250/hour with a 2-hour minimum; covered retainer clients never pay hourly.
Platform expertise
We know the platform you’re leaving
Our engineers have been building commerce since 2011 – on Magento and Adobe Commerce, Salesforce Commerce Cloud, BigCommerce and WooCommerce – so your data model, URLs and custom business logic are understood before anything moves, not discovered halfway through.
-
Shopify Plus pricing guide
Where we move you. Shopify runs hosting, security, PCI compliance and core updates; Plus adds checkout extensions in the steps before payment, Shopify Functions in your own apps and B2B at scale – company-specific catalogs, deposits and expansion stores. Subscription prices as of October 2026:
- Three-year term
- From $2,300/month
- One-year term
- From $2,500/month
-

- Timeline
- 8–24+ weeks

- Typical range

A background in enterprise builds
The work that stuck from our early years was the hard kind: enterprise Magento installs and Salesforce implementations with six-figure budgets – the same kind of store that now moves to Shopify Plus.

The projects others turned down
Clients keep telling us other developers said it couldn’t be done – custom inventory systems, gated trade pricing, stores mid-rescue. Those are the ones we take.

In merchants’ own words
Quoted word for word from the Shopify Partner Directory. Some reviews use our full name, Outstanding Experience.
“…We have had some complex needs on our site, where other developers have said it could not be done. ‘Outstanding Experience’ has been able to get it done every time.”

“OUXP was highly communicative and quick to respond. Store migration is successfully done by a top-notch team on Shopify. They met the requirements and provided high-quality work, just as requested.”

“We brought in OUXP for some CRO fixes and theme/app compatibility issues, and they absolutely overdelivered. They didn't just patch things - they tracked down the real root causes, cleaned up our theme and got all the key apps working together smoothly. The store works faster, more solid, and we're seeing a clear bump in conversions.”

Industries we build for most often
Each one breaks in a different place – here is where.

High-SKU catalogs, size and variant complexity, and drop launches that spike traffic.

Beauty & cosmetics
Subscriptions, bundles, shade-finder UX and media-rich pages that still need to load fast.

Health & wellness
Compliance-sensitive claims, subscriptions and practitioner channels alongside DTC.
-
Industrial & manufacturing
Deep category trees, spec-heavy products, wholesale pricing, quotes and ERP integration.
CleanFlow case study -

Luxury
Editorial storytelling without slow pages, trade or VIP gating, sample orders and custom requests.
Wall Snobs case study -
B2B commerce
Company accounts, gated price lists, quote-to-order, net terms and ERP sync on Shopify B2B – with Shopify Plus when you need company-specific catalogs or deposits.
-
Selling something else?
Four answers decide how we build any store: the shape of your catalog, who sees which price, how customers buy again and which system holds the truth.
Where every project starts
Platforms and apps we work with
Integrations start from the stack you already run. We use a maintained connector when it fits and build custom only when it doesn’t.

What happens after you get in touch
The same four steps for planned work, from a single feature to a full migration – and nothing ships without your approval.
- 1
Tell us what is happening
Share the store, the goal and any constraints. An engineer replies within 30–60 minutes during business hours.
- 2
Agree the right scope
Decide what to change, what it depends on and how success will be checked.
- 3
Review the work as it takes shape
Make decisions with working previews and clear explanations. Nothing touches production until you approve it.
- 4
Launch and hand over
Your team gets the documentation it needs, and together we agree what to measure next.
Questions before you hire us
Timelines, costs, SEO and support after launch. Something else? Ask an engineer.
How long does a migration to Shopify Plus take?
WooCommerce migrations usually take 3–10 weeks and BigCommerce 4–12 weeks. Magento takes 8–24+ weeks, and Adobe Commerce and Salesforce Commerce Cloud 10–24+ weeks, depending on catalog structure, integrations, B2B requirements and checkout logic. The free migration assessment places you in a timeline band within 2 business days; a fixed timeline with milestones is agreed in writing before work starts.
What does a Shopify Plus migration cost?
Most migrations cost $25,000–$250,000+: WooCommerce $25,000–$60,000, BigCommerce $30,000–$70,000, Magento $50,000–$180,000, Adobe Commerce $60,000–$200,000 and Salesforce Commerce Cloud $80,000–$250,000+. B2B, ERP integrations and custom checkout logic move a project up its range. The free assessment gives you a cost band; the price is fixed in writing before work starts, with SEO preservation included. The migration cost guide breaks down what drives each figure.
Will we lose SEO rankings when we migrate?
Lasting losses are avoidable, but nobody can honestly promise zero movement: rankings can fluctuate briefly after any replatform while search engines recrawl the new URLs. We keep that dip short with a per-pattern 301 map for every URL, carried-over titles, meta descriptions and structured data, a fresh sitemap and rank monitoring after launch. SEO preservation is included in every migration, never an add-on.
Which platforms does OUXP migrate to Shopify Plus?
Magento 1 and 2, Adobe Commerce, Salesforce Commerce Cloud, BigCommerce and WooCommerce – including B2B, multi-store and multi-currency setups. Magento 1 stores, unsupported since June 30, 2020, move straight to Shopify Plus without a Magento 2 upgrade first. Each of the five migration paths has its own page with timelines, price bands and the technical problems we solve.
Do you offer support after the migration?
Yes. Most clients continue on a monthly retainer covering maintenance, troubleshooting and theme customization, plus CRO and A/B tests on Growth and Dedicated. There are three tiers – Essential at $2,500/month (20 hours), Growth at $5,000 (45 hours) and Dedicated at $9,500, which buys 90 hours or a dedicated engineer for your store. Every tier gets a first response within 30–60 minutes during business hours. The optional 24/7 emergency add-on adds round-the-clock cover with a 2-hour first response, and Dedicated includes it.
Does AI make a migration faster or cheaper?
Mainly faster and safer. AI tooling takes on the repetitive parts of a migration – drafting the data and URL mapping, generating test runs that compare products, prices and redirects between the old and new store, and first-pass code review and QA – so timelines shorten and errors surface earlier. A senior engineer reviews every AI-assisted output, and people still plan and rehearse the cutover. Price still depends on catalog, integrations and checkout logic.
