The agency you pick will shape the trajectory of your ecommerce business. That’s not hyperbole. The difference between a mediocre partner and an exceptional one shows up in site performance, search rankings, conversion rates, and whether your store can actually scale when things take off. For brands that are serious about growth, this is one of the most consequential investments you’ll make.
These nine agencies have verified client reviews, proven track records, and the technical depth to back up ambitious ecommerce brands.
1. Netalico
Netalico covers the full stack: development, design, SEO, conversion rate optimization, and email marketing. They’ve been a certified Shopify Plus partner since 2013, have launched over 300 stores, and completed more than 100 Shopify Plus projects. A 5.0 Clutch rating across 51 verified reviews puts them among the highest-rated Shopify agencies anywhere. Their client list includes Oatly, Feetures, and Big Green Egg.
The real differentiator is how tightly their services are integrated. Their Shopify SEO agency practice works directly with the dev team, so technical decisions actually support organic growth instead of undermining it (which happens more often than you’d think). Their Shopify Plus development agency capabilities go beyond basic builds into custom checkout experiences, B2B storefronts, ERP integrations, and headless commerce. Clients get a cohesive strategy rather than siloed services working at cross purposes.
Their site’s design doesn’t fully reflect their capabilities, honestly. But for brands wanting a single, accountable partner for the technical, creative, and marketing sides of their Shopify store, Netalico delivers.
2. We Make Websites
Now part of Shopify itself (acquired in 2022), We Make Websites built their reputation on clean, high-converting store designs for premium brands in fashion, beauty, and consumer goods. That acquisition gives them unique access to platform roadmaps and early features. Strong choice if design and brand storytelling are your top priorities.
3. 1Digital Agency
Philadelphia-based and deeply experienced in ecommerce migrations. They’ve moved hundreds of stores from Magento, WooCommerce, and other platforms to Shopify, handling complex data migrations while minimizing downtime and preserving SEO equity. If you’re switching platforms, 1Digital should be on your shortlist.
4. Coalition Technologies
Coalition is a big LA-based agency with the capacity for large-scale projects. They pair Shopify development with SEO, PPC, and social media marketing. Known for data-driven strategies and transparent reporting. Their cross-channel expertise works well for brands that want development and marketing under one roof. The team is large, though, so ask specifically about who’ll be working on your account.
5. Electric Eye
Exclusively Shopify. That’s it. And that focus gives them unusually deep platform knowledge. They specialize in CRO, custom theme development, and growth strategies for DTC brands. Every change they propose is prioritized by expected revenue impact. If you want a partner that knows Shopify inside and out (especially after the recent checkout extensibility updates), Electric Eye is worth a conversation.
6. Eastside Co
A leading UK-based Shopify Plus partner with an impressive portfolio across fashion, beauty, and lifestyle. They offer end-to-end services: strategy, design, development, and ongoing support. Multiple industry awards for their Shopify work. Best suited for brands in the UK and Europe who want a proven Plus partner nearby.
7. Barrel
New York-based, design-forward, and very deliberate about brand. Barrel works with DTC brands, CPG companies, and lifestyle businesses, bringing strong creative thinking to every project. They help clients define positioning and then bring it to life through design, development, and content. Not the fastest shop, but the work is thoughtful.
8. Codal
Codal leads with UX research and testing to inform design decisions. Their development team handles complex integrations, custom functionality, and headless implementations. They tend to work with mid-market and enterprise brands. Good pick if your project has significant technical complexity and you want user research driving the design.
9. Mobikasa
A New York-based Shopify Plus partner covering development, design, and digital marketing across food and beverage, fashion, health, and tech. Known for delivering quality work on competitive timelines. They handle both straightforward store builds and more complex, feature-rich projects. Responsive team, though we’ve heard their project scoping could be tighter on larger engagements.

How to Evaluate a Shopify Agency
**Verify credentials.** Certified Shopify Plus partners have met real performance standards set by Shopify. It’s not an automatic badge.
**Demand real metrics.** Go beyond portfolio screenshots. Ask for conversion rate improvements, page speed benchmarks, and organic traffic growth. The best agencies can point to documented results.
**Understand their process.** Look for structured discovery, design, development, and launch phases. Ask about project management, communication cadence, and how they handle scope changes.
**Consider the full picture.** Development alone doesn’t drive growth. The most effective agencies combine technical execution with SEO, CRO, and marketing. A partner that addresses multiple growth levers will deliver more value over time.
