Netalico is a Shopify enterprise agency and a Shopify Plus Premier Partner, the most selective tier of Shopify's partner program. We build, migrate, and support Shopify Plus stores for mid-market and enterprise brands, and 85% of our clients stay with us on ongoing monthly retainers after launch. The same senior team that builds a store keeps running it, so nobody has to relearn the codebase when something breaks during a sale.
Mark Lewis founded Netalico in 2011 while he was still an engineer at NASA, and left NASA to run it full-time in 2013. We have been a Shopify Partner since 2016 and have delivered hundreds of Shopify builds since.
What enterprise brands need from a Shopify agency
Enterprise Shopify work is less about themes and more about everything around the store: ERP and order management integrations, B2B pricing, multiple storefronts, subscriptions, and migrations that can't lose search traffic or orders. Most enterprise teams also have internal developers and marketers, so the agency has to fit into existing processes rather than replace them.
That shapes how we work:
- One team from build through support. The engineers who scope and build the store stay on it after launch, under a retainer.
- A dedicated project manager for every client, backed by senior developers, UX strategists, and CRO specialists.
- Everyone is in-house. Nothing is subcontracted. Our team works across the Americas, with hubs in New York, Los Angeles, San Francisco, and Miami plus colleagues in Canada and Brazil, and the whole team overlaps the US business day.
- No long-term contracts. Retainers run month to month with 30 days' notice. Clients stay because the work is good, not because they are locked in.
Shopify Plus capabilities for enterprise stores
Our Shopify Plus development work covers the requirements enterprise brands bring to the platform:
- Integrations: NetSuite and other ERPs, custom order management, PIMs, and specialized payment gateways.
- B2B on Shopify Plus: customer-specific catalogs and price lists, wholesale ordering, and user roles for buyer companies.
- Multi-store and international: several brands or regions on separate storefronts, with shared operations behind them.
- Custom storefronts: headless builds where they earn their cost, plus custom filtering, product configurators, and bundle builders where off-the-shelf apps fall short.
- Checkout and subscriptions: checkout extensions, Shopify Functions, and subscription platforms such as Recharge.
- Performance and compliance: Core Web Vitals, accessibility work, and technical SEO built into the build rather than bolted on later.
We also use AI to speed up development and migration work, with senior engineers keeping control of quality on every release.
Enterprise migrations to Shopify Plus
Many of our enterprise engagements start as a replatform. We move brands to Shopify Plus from Magento, BigCommerce, WooCommerce, and Salesforce Commerce Cloud. Each migration is planned around three risks: losing organic rankings, losing customer and order history, and breaking integrations the business depends on. URL mapping, redirect testing, data validation, and a rehearsed cutover are part of every project, not extras.
Results for enterprise and high-growth brands
- Oatly: we ran the US site transition during Oatly's global headless redesign and rebuilt its Recharge subscription flows, which produced a 188% increase in monthly recurring subscription revenue within three months.
- VYBES: a UX and UI strategy with custom Shopify development delivered a 90% increase in revenue and 50% more sessions, and lifted the conversion rate from 2.5% to 6%.
- Crossrope: a complete migration to Shopify during the home fitness boom, followed by a 90% revenue increase.
- Audio Advice: a Magento to Shopify Plus migration with custom product listing pages, advanced filtering, and faster page loads.
- Big Green Egg: a full Shopify Plus migration, with Netalico continuing to support the store afterward.
- Limitless Walls: a client since 2016. We maintained its Magento 1 store, migrated it to Shopify in 2022, and still support it today.
Other brands we have worked with include Getty Images, Rifle Paper Co, Yasso, Ministry of Supply, and POPSUGAR.
How enterprise engagements are priced
Builds and migrations are scoped as projects, typically from $25,000 to more than $250,000 depending on integrations, catalog complexity, and the number of storefronts. Ongoing work runs on monthly Shopify retainers from $3,700 to $10,000, with the average client around $4,500 a month. Larger enterprise programs are scoped individually. Retainers include project management, monitoring, and a steady release cycle, so the store improves every month instead of between big projects.
Brands that need senior technical leadership without a full-time hire can also work with Mark directly as a fractional Shopify CTO.
Who leads the work
Mark Lewis has more than 20 years of engineering experience, including enterprise systems work at NASA and Hewlett Packard, and holds an MBA from The Wharton School. He also serves as a fractional ecommerce and Shopify CTO for several larger brands. That background shows up in how we run enterprise projects: code freezes before launches, version-controlled changes, and nothing shipping without independent testing.
