Two candidates can both list "eCommerce" on their resume and have spent their careers on opposite sides of the same transaction. Here's which skills cross over, which ones don't, and how to tell before you hire.
It is one of the most common questions we hear from hiring managers: "This candidate has great eCommerce experience, but it's all at a retailer. Will it work here?" Or the reverse: a retailer looking at a strong candidate from a CPG brand and wondering whether brand experience translates to running a digital store.
The honest answer is that it depends on the role. Brand-side and retailer-side eCommerce share a vocabulary (conversion, content, retail media, the digital shelf), but they sit on opposite sides of the same relationship. One side sells to the shopper through the retailer. The other side decides what the shopper sees. Some skills cross that line easily. Others take years to build.
Brand-side eCommerce professionals work for the company that makes the product: a CPG manufacturer, an apparel brand, a consumer electronics company. Their job is to grow that company's sales online. For many brands, most of that revenue runs through retailer websites like Amazon, Walmart.com, Target.com, and grocery and specialty sites, with a DTC site alongside. Their customer is the retailer as much as the shopper.
Retailer-side eCommerce professionals work for the company that sells many brands. Their job is to run the digital store: decide the assortment, merchandise the site, set prices and promotions, keep inventory and fulfillment working, and, at a growing number of retailers, sell advertising to the brands on their shelves. Their customer is the shopper, and the brands are their suppliers and advertisers.
| Area | Brand-side eCommerce | Retailer-side eCommerce |
|---|---|---|
| Core question | How do we win more of the shopper's spend on every site that sells us? | How do we make the whole store more profitable and easier to shop? |
| Scope | One brand or portfolio, many retail partners | Many brands, one storefront |
| Main relationship | Retail buyers and category managers | Shoppers, plus vendors and advertisers |
| Typical metrics | Sales by retailer, share of category, content compliance, retail media return, trade spend | Traffic, conversion, basket size, category margin, inventory turns, ad revenue |
| Data access | Partial: what the retailer shares, plus syndicated data | Full first-party data across every brand and shopper |
| Source of leverage | Brand demand, investment, and the relationship | Control of the shelf, the traffic, and the shopper data |
That last row explains a lot. On the retailer side, you are the customer. On the brand side, you are the one asking for space. People who have only worked one side often underestimate how much that changes the day-to-day job.
Often, and it is one of the most sought-after moves in the market. A former merchant, eCommerce buyer, or category manager at a major retailer brings something brand teams cannot easily build: firsthand knowledge of how the retailer makes decisions. They know what a buyer looks for in a business review, how the retailer weighs margin against traffic, and which data actually moves the conversation.
That makes retailer alumni a strong fit for brand roles in sales and account management, digital shelf, and marketplace management. Our guide to hiring a Key Account Manager covers why that perspective has become so valuable.
The gaps are real, though, and worth screening for:
Less automatically, but it works better than many retailers expect in the right roles. The challenge is scope and perspective. A retailer-side merchant or site leader manages an entire assortment, makes vendor-neutral decisions every day, and runs high-volume operations where a small change can affect millions of sessions. Someone who has spent years championing one brand's products has to learn to think about the whole category, including competitors they used to fight.
Where brand-side candidates tend to succeed at retailers:
Where it transfers less easily: merchant and buying roles that require assortment planning and vendor negotiation from the retailer's side, and site or fulfillment operations at large scale, unless the candidate ran a high-volume DTC business.
The question is not "brand or retailer?" It is "has this person ever had to think like the other side?" The candidates who transfer best already have.
| Hiring for | Strong source from the other side | Watch for |
|---|---|---|
| Brand: eCommerce Key Account Manager | Retail buyer, merchant, or eCommerce category manager | Comfort with selling instead of buying |
| Brand: Digital Shelf or Content Lead | Retailer site merchandising or content operations | Experience across multiple retailers, not just one |
| Brand: Retail Media Manager | Retail media network account or campaign manager | Ability to judge spend against brand margin |
| Retailer: Retail Media Sales | Brand-side or agency retail media buyer | Understanding of the retailer's full advertiser mix |
| Retailer: Vendor Partnerships | Brand-side key account or eCommerce manager | Vendor-neutral judgment |
| Retailer: Site Merchandiser | Brand DTC site manager | Experience managing a large, multi-brand catalog |
| Either side: Analytics | Analysts from either side | Familiarity with the data the new side has (or doesn't have) |
For analytics roles, the underlying skills transfer well in both directions. The bigger adjustment is the data itself, which our Analytics & Data Science practice sees often. A retailer analyst moving to a brand will lose access to data they took for granted, while a brand analyst moving to a retailer suddenly has far more of it.
The fastest way to test transferability is to ask candidates to reason from the other side's point of view. People who can do that with specifics have usually spent time working closely with their counterparts, and they ramp faster.

For brand-side candidates interviewing at a retailer:
Weaker answers tend to default to the logic of the job the candidate has now. A brand candidate who answers every retailer question by explaining how to grow one brand, or a retailer candidate who assumes a brand has the same data and leverage, will need more time to adjust. Our post on vetting omnichannel experience covers similar screening techniques, and Brand Manager vs. Category Manager explores the same divide at the marketing and merchandising level.
Brand-side eCommerce professionals work for a manufacturer or brand and sell that company's products, often through retailer websites such as Amazon, Walmart.com, and Target.com, and sometimes through the brand's own DTC site. Retailer-side eCommerce professionals work for the retailer and run the digital store itself: the assortment, site merchandising, pricing, promotions, fulfillment, and in many cases a retail media network that sells advertising to brands.
Often, yes, especially into account management, digital shelf, and retail media roles. A former retailer merchant or eCommerce buyer knows how the retailer makes decisions, what data it values, and how to win in its business reviews. The gaps tend to be brand building, owning a single P&L for a narrower product line, and working without the leverage of being the customer.
Less automatically. Retailer roles require managing an entire assortment across many brands, making vendor-neutral decisions, and running high-volume site and fulfillment operations. Brand-side candidates who have owned a DTC site, run marketplace operations, or bought retail media at scale can transfer well, particularly into retail media sales, vendor partnership, and site merchandising roles.
Ask a retailer-side candidate how they would pitch a category buyer on a new item using only the data the brand can see. Ask a brand-side candidate how they would decide which of several competing brands gets the top spot on a category page. Strong candidates answer from the other side's point of view with specifics, while weaker candidates default to the logic of the job they have now.
Key account and eCommerce account management roles at brands are often filled well by former retail buyers and merchants. Retail media network sales roles at retailers are often filled well by people who bought retail media on the brand side or at agencies. Analytics and fulfillment roles also tend to transfer in both directions because the underlying skills are similar.
