Compare DIY, an in-house team and an external marketplace department for running Amazon and European marketplace operations. [Gozde Mert](https://www.ecomglue.com/blog/author/gozde-mert) Oct 22, 2026 --- Throughout this series, we have looked at what it takes to run marketplace operations well: [the pillars of ecommerce management](https://www.ecomglue.com/blog/ecommerce-management-guide), [multichannel listing management](https://www.ecomglue.com/blog/multichannel-listing-management), [inventory and order sync](https://www.ecomglue.com/blog/marketplace-inventory-order-sync), [account health and EU compliance](https://www.ecomglue.com/blog/marketplace-account-health-eu-compliance) and [peak-season preparation](https://www.ecomglue.com/blog/q4-marketplace-operations-checklist). That leaves the question every growing brand eventually faces: who should actually do this work? ## The three models ### 1. Do it yourself Common in the early stage. A founder or general ecommerce manager runs the marketplace accounts alongside everything else. **Works when:** you sell on one or two marketplaces, in one country, with a small catalog. **Breaks when:** you add channels, countries or SKUs. Listing errors pile up, compliance requirements get missed, and growth slows because nobody has time to work on it. ### 2. Build an in-house marketplace team You hire specialists: a marketplace manager, listing and content specialists, someone for inventory and operations, translators or native speakers per market. **Works when:** marketplaces are your main revenue channel at scale, and you can justify a permanent, multi-person team. **Watch out for:** - Hiring cost and time. Experienced marketplace specialists are hard to find, especially with knowledge of several platforms and markets. - Knowledge gaps. One person rarely knows Amazon, Otto, Bol, Cdiscount and eBay equally well, plus the regulatory side of each country. - Tool costs. Multichannel software, analytics and compliance services add up. - Single points of failure. When a key person leaves, knowledge often leaves with them. ### 3. Work with an external marketplace department An agency runs your marketplace operations end to end, with the team, tools and processes already in place. **Works when:** you want to expand into new marketplaces or countries quickly, without building a team first, or when your in-house team needs specialist support. **Watch out for:** agencies that only do advertising. Many agencies offer marketplace ad management. Far fewer can set up accounts, build and map catalogs, sync inventory, manage compliance and handle day-to-day account operations across several countries. ## A side-by-side comparison | | Do it yourself | In-house team | External marketplace department | | --- | --- | --- | --- | | Time to launch a new market | Slow | Medium, after hiring | Fast | | Multi-marketplace expertise | Limited | Depends on hires | Built in | | Fixed cost | Low | High | Medium, scalable | | Tools and processes | Build yourself | Build yourself | Included | | Control | Full | Full | Shared, with reporting | | Scales with new channels | Poorly | With more hiring | Yes | ## Questions to ask before you outsource - **Which marketplaces and countries do they actually operate?** Ask for examples, not just a logo list. - **Do they cover operations, or only ads?** Listings, inventory, compliance and account health should be part of the scope. - **What tools do they use?** A proper multichannel platform is a sign of a scalable process. Spreadsheets are not. - **How do they handle localization?** Native-language content for each market makes a measurable difference. - **What will you see each month?** Clear reporting by channel, country and product line. - **Who owns the accounts and data?** You should. ## How Ecomglue works We act as our clients' external marketplace department across Europe, the US and Turkey. That means: - **Marketplace expansion:** choosing the right channels and countries, opening accounts and handling onboarding paperwork. - **Listing management:** category-based product data, variations, field and attribute mapping, and ongoing error resolution, run through **StoreAutomator**, where we are an agency partner. - **Account management:** Seller and Vendor Central operations, price and deal management, FBA and inventory, and account health monitoring. - **Content and localization:** listings, A+ Content and brand stores adapted for each market. - **Reporting and custom tools:** consolidated dashboards and integrations when off-the-shelf tools are not enough. Advertising is part of what we do, but it sits on top of a well-run operation, not in place of one.
