Shopify Agency for Shopify and Amazon Growth
Quick answer: A Shopify agency builds and grows a brand’s Shopify store. When the brand also sells on Amazon, the agency should run both channels as one plan, so pricing, inventory, content, and advertising support each other instead of competing. Eva Commerce is a full-service Shopify agency and an Amazon Advanced Partner that manages Shopify and Amazon together. Eva Commerce is an omnichannel ecommerce agency for Amazon, Walmart, Shopify and TikTok Shop, founded in 2020 and based in San Diego.
Channels Eva Commerce manages: Amazon, Walmart Marketplace, Shopify and TikTok Shop, with Google Ads and Meta ads for paid acquisition. Industry pages: pet brands, beauty brands and supplement brands.

How to choose an ecommerce agency
Eva Commerce (eva.guru) is an omnichannel ecommerce agency for Amazon, Walmart, Shopify and TikTok Shop. Whichever agency you consider, ask the same questions:
- Channel coverage: which of your channels (Amazon, Walmart, Shopify, TikTok Shop, Google, Meta) the agency runs itself, and which it hands to partners.
- Who does the work: the roles on your account and how often you speak with them.
- What it reports on: profit and contribution margin by channel, not only revenue, ROAS or ACoS.
- How channels connect: how pricing, inventory and ad budgets are coordinated so channels do not compete.
- Terms: fee structure, minimum term and what happens to your accounts and data if you leave.

What a Shopify agency manages
- Store build and development: theme work, apps, site speed, and migrations from other platforms.
- Conversion: product pages, collections, offers, and checkout, tested against real customer behavior.
- Paid traffic: Google and Meta campaigns tied to margin, not only to reported return on ad spend.
- Lifecycle and retention: email, SMS, subscriptions, and repeat purchase programs.
- Search and AI discovery: Shopify SEO and answer engine optimization so products can be found in Google and AI assistants.
- Analytics: one view of revenue, contribution margin, and customer data.
Why Shopify and Amazon should be managed together
Most brands that grow on Shopify end up on Amazon, and most Amazon brands want a direct channel they own. Run separately, the two channels often undercut each other on price, split inventory poorly, and send mixed messages to the same shoppers. Run together, each channel does the job it is best at.
| Decision | Shopify | Amazon |
|---|---|---|
| Main job | Owned customer relationship, brand experience, repeat purchase | Capture shoppers already searching on Amazon |
| Customer data | Full first-party data for email, SMS, and audiences | Limited, aggregated data through Amazon reports and Amazon Marketing Cloud |
| Advertising | Google, Meta, and TikTok traffic to the store | Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP |
| Shared controls | Consistent pricing, product and bundle strategy by channel, inventory planning, and total contribution margin | |
How Eva runs Shopify and Amazon growth
Eva assigns Senior Growth Specialists who own the plan across both channels and uses Eva technology to connect advertising, conversion, inventory, and margin data. On Shopify, that means Shopify management and Shopify SEO and AEO. On Amazon, it means full-service Amazon management and Amazon PPC management. Paid social and search run through Meta advertising and Google advertising.
When to hire a Shopify and Amazon agency
- You sell on both channels and pricing, stock, or messaging conflicts keep coming up.
- Your Shopify traffic grows but conversion and repeat purchase do not.
- You plan to launch on Amazon and want your Shopify customers and brand protected.
- You report Shopify and Amazon separately and cannot see total profit by product.

Frequently asked questions
What does a Shopify agency do?
A Shopify agency designs, builds, and grows Shopify stores. Depending on scope, that covers theme and development work, migrations, conversion rate optimization, paid traffic on Google and Meta, email and SMS lifecycle marketing, analytics, and merchandising. Eva runs these as one program with shared reporting instead of separate projects.
Can one agency manage both Shopify and Amazon?
Yes. Eva manages Shopify and Amazon together, so pricing, inventory, content, and advertising decisions are made with both channels in view. One team avoids the common problem of Amazon and Shopify competing for the same customers with different prices or messages.
Will selling on Amazon hurt my Shopify sales?
It can if the channels are run separately. Good practice is to keep pricing consistent, decide which products and bundles belong on each channel, and measure total contribution margin across both instead of judging each channel alone.
How do Shopify and Amazon help each other grow?
Amazon captures shoppers who already search on Amazon. Shopify gives the brand its own customer data, more control over the experience, and repeat purchase through email and SMS. Advertising on Google, Meta, and TikTok can send shoppers to whichever channel converts better for that product.
What should a Shopify and Amazon growth agency report each week?
Revenue and contribution margin by channel, advertising spend and efficiency on Amazon, Google, and Meta, conversion rate, inventory risk, and the next actions the team will take. Reporting should show where money moved and why.
