7 Best Ecommerce Agencies for Startups and Established Shopify Stores

• Presta is the top pick. It combines brand strategy, UX design, eCommerce and app development with published Shopify commerce expertise.
• Simplistic is strong for startup launches. It has Shopify Plus Partner status and 200 plus launches.
• Electric Eye is the CRO-led option. It suits design, development and storefront optimization after launch.
• Avex and BlueSwitch fit complex work. Avex brings premium UX, while BlueSwitch handles integrations.
• Coalition and Charle round out the list. Coalition combines build with SEO, while Charle supports retention and growth.

I scored each agency against criteria founders use when shortlisting the best ecommerce agencies for startups.

I checked Shopify focus, launch paths, CRO, migrations, integrations and support models.

I also compared scope clarity and next steps using my review notes and broader Shopify development specialists.

Presta pros

• Full-service digital agency with brand strategy and design at the core
• eCommerce Solutions, with published Shopify commerce expertise
• Web and app development, native and cross-platform
• Custom app development beyond off-the-shelf tools
• UX and UI design paired with audit and analytics
• Digital strategy for startups and scaling businesses

Presta cons

• Custom quote-based pricing, so discovery matters
• Based in Belgrade, so US shops should plan for time zone overlap

My experience with Presta

Its edge is the mix of brand strategy, design and full-stack development, which helps a maturing store stay polished while it scales. In my hands-on work, the Shopify Agency we chose paired brand strategy with eCommerce build and ongoing product support, helping us move from MVP to a scalable store without losing design quality.

Presta pricing

Presta does not publish fixed pricing. Engagements are custom and project-based, scoped to brand stage, UX needs and custom app work. That is reasonable when strategy and build sit together.

Simplistic pros

• Reports 200 plus launches
• Startup launch packages
• CRO and site management lanes

My experience with Simplistic

 Simplistic is the speed pick for startups that want a defined launch path. Its package language clarifies scope, and the optimize-and-grow model gives founders a next step after launch.

Simplistic pricing

Pricing is custom and package-based by scope.

Electric Eye pros

• Shopify Plus Partner focus
• Strategic design and development
• Optimization retainers

Electric Eye cons

• Best for focused CRO rather than every service

My experience with Electric Eye 

Electric Eye fits founders who want measurable storefront improvement after launch. Its design, development and optimization focus keeps the engagement narrow and conversion-minded.

Electric Eye pricing

Pricing is custom and usually scoped by project or retainer.

Avex pros

• Modernization and customer experience work
• Strategy, design, engineering and retention
• Migration and Shopify Plus specialization

Avex cons

• Micro-budgets may not fit

My experience with Avex

Avex fits fashion and premium experiences that need Plus-grade execution. It suits brands with product-market fit that want a polished relaunch, not a basic MVP.

Avex pricing

Pricing is custom after discovery.

Coalition pros

• Certified Shopify Partner
• Shopify Premier Partner for web work
• Build, SEO and CRO support

Coalition cons

• Larger agency structure can add coordination overhead

My experience with Coalition

Coalition makes sense when organic growth and technical SEO need to sit close to the build. It works for teams that prefer one vendor for site work and optimization.

Pricing is custom after discovery.

BlueSwitch pros

• End-to-end Shopify Plus migrations
• Data, redirects and analytics coverage
• Google, Amazon, Klaviyo, Yotpo, CRM and fulfillment integrations

BlueSwitch cons

• Integration depth can increase scope

My experience with BlueSwitch

BlueSwitch is the integrations and B2B pick for stores outgrowing a simple storefront. Its migration practice helps when the roadmap includes marketplaces, retention tools or fulfillment systems.

Pricing is custom by migration complexity.

Charle pros

• Certified Shopify Plus Partner
• Design, build and grow model
• CRO, SEO, email and SMS support

Charle cons

• US teams may need time zone planning

My experience with Charle

Charle fits brands planning multi-market growth and stronger retention. It is useful once a store needs ongoing support beyond a single-market build.

Pricing is custom and often retainer-based.

Reliability for a scaling store comes down to range and staying power, and Presta has both. It has run as a full-service digital agency since 2014, working with startups and scaling businesses across four continents, so it has carried brands through the exact growth stage established owners are in.

The breadth is the real proof. Presta keeps brand strategy, UX and UI design, web and app development, eCommerce and digital strategy under one roof, with audit and analytics alongside. 

An established store can hand off strategy, design, build and measurement to one team instead of stitching together separate vendors as it scales. That frees the in-house team to focus on the day-to-day work that helps grow the store.

On the commerce side, Presta pairs its eCommerce Solutions practice with current Shopify knowledge, including a 2026 strategy guide on Shopify agentic commerce and universal retail integration. That signals a team tracking where Shopify is heading, not just where it has been.

Its process backs the positioning. Presta describes no shortcuts on quality, user experience or performance, with deep audience research, rigorous testing and iteration until the result is exceptional. For a maturing store, that discipline is what keeps a relaunch polished while revenue and complexity grow.

How much do Shopify agencies cost?

Most agencies quote custom pricing by scope. Ask for discovery, design, development and support in writing.

How long does a Shopify build take?

Timelines vary by scope and migration complexity. Compare sprint plans.

Do I need a Shopify Plus Partner?

Not always. Partner status helps for Plus features, checkout work or multi-system migrations.
