Magento has powered online stores since 2008. Today, it’s still a top-three eCommerce platform, and it leads the way in B2B. In fact, it runs more than 100,000 live stores worldwide. It’s flexible, customizable, and feature-rich. That’s why mid-market and enterprise brands keep choosing it.
But that power comes with a catch. Magento rewards the technical depth needed to run it well, and most merchants don’t have that depth in-house. So the real question is simple: how do you pick a Magento eCommerce agency you can trust? And how do you do it without getting lost in a crowded field of vendors?
We can help. Atwix is an Adobe Gold Solution Partner and the #1 contributor to Magento’s open-source codebase since 2018. In short, we’ve spent nearly two decades inside this ecosystem. Here’s what actually matters when you evaluate a Magento agency.
What does a Magento eCommerce agency do?
A Magento eCommerce agency builds and maintains online stores on Magento Open Source or Adobe Commerce. The work covers a lot. For example, it includes store development, custom modules, and theme and UX design. It also includes ERP and back-office integrations, performance tuning, security, migrations, and ongoing support.
For B2B sellers, the job goes further. Think buyer portals, customer-specific pricing, shared catalogs, and automated order workflows. Generic platforms simply can’t handle that level of complexity.
The best agencies don’t just use Magento. Instead, they contribute to it, hold senior Adobe certifications, and show a portfolio that proves real experience.
7 things to look for in a Magento eCommerce agency
1. Adobe partnership and certification depth
First, check the agency’s Adobe partnership tier and certifications. These signal real expertise. Adobe — Magento’s owner — ranks its top partners as Gold and above. As a rule, that ranking tracks closely with hands-on skill.
For example, Atwix holds more than 200 certifications across Adobe, Shopware, and Shopify. That total includes 47 Adobe Certified Experts and 5 Adobe Certified Masters. So when you vet a partner, ask how many Master- and Expert-level certifications they actually hold. Don’t just accept “we’re certified.”
Region matters too. Different markets shop in different ways. Therefore, an agency that knows your region gives you an edge. Atwix specializes in both North American and EMEA markets, and our team are Magento 2-certified Solution experts.
2. Open-source contribution and community standing
Certifications show what an agency has learned. Code contribution shows what it can build. Magento improves through its open GitHub codebase, and the top contributors understand the platform at a deep level.
Atwix has been the #1 contributor to that codebase since 2018. As a result, we get faster answers when something breaks. So pick an agency the community knows and respects.
3. Presence on Adobe’s Solution Partner directory
If you plan to outsource Magento development, start with the source of truth. Adobe keeps a Solution Partner directory of vendors it trusts. You can filter it by region, specialization, and tier. As a result, building a shortlist takes minutes. And if an agency isn’t listed, ask why.
4. Track record and longevity
Magento changes fast. For instance, Adobe Commerce 2.4.9 shipped in May 2026 with support for PHP 8.5 and Symfony 7.4. Meanwhile, Adobe Commerce as a Cloud Service added a versionless SaaS edition. An agency that has tracked these shifts will handle change far more safely than a newcomer.
Atwix has worked with Magento almost since launch. Our projects range from full builds to redesigning one of Europe’s largest delivery systems, and we handle core website development too. We also ranked No. 2327 on the 2025 Inc. 5000 list. In short, longevity means we’ve likely seen your edge case before.
5. A portfolio relevant to your niche
A deep portfolio matters. Still, relevance matters more. So look for projects that match your scale and complexity.
Take Byrne Electrical Specialists, for example. The brand moved to a B2B marketplace, and Atwix integrated its ERP, enabled non-catalog sales, and added Magepack for faster frontend performance. When you review a portfolio, ask a few questions. Are the projects similar to yours? Do the results inspire confidence? And does the agency focus on B2B commerce if that’s your world?
6. A real client-success model
Client success is where many agencies fall short. Atwix runs a model we call the “client orbit,” and it keeps the client at the center of every project. For example, live calls usually include three roles: a Project Manager, a Tech Lead, and a Client Success Manager. As a result, the work stays tied to your goals, not just to tickets. So ask who you’ll actually talk to each week.
7. Flexibility and post-launch partnership
Launch day is the start, not the finish. The right Magento eCommerce agency adapts as your needs change. Consider Magnanni, a luxury footwear brand. After the build, Atwix added backorder tracking, live stock status, and fixes for stubborn caching. Because of that ongoing work, the store kept improving. In fact, most strong Magento relationships last years, not single projects.
Putting it together
Use these seven criteria to shortlist a Magento eCommerce agency with confidence:
- Adobe Gold partnership and senior-level certifications
- A record of open-source contribution and community leadership
- A verified spot on Adobe’s Solution Partner directory
- Longevity across Magento’s major platform shifts
- A portfolio that fits your industry and complexity
- A clear client-success model with named, accountable roles
- Flexibility to keep improving the store after launch
