A Tool Review: How CTOs and CIOs Should Evaluate Platform Expertise Depth Across eCommerce Platforms
For CTOs, CIOs, and senior IT buyers, the question of platform expertise depth is most often asked about an agency partner being considered for an engagement. The question is harder to answer well than it appears. Vendor marketing makes every agency sound deep. Reference calls produce uneven signals depending on which references the agency provides. The structural evaluation of platform expertise depth requires the buyer to apply consistent criteria across platforms, with awareness of what depth means specifically on each major platform.
This review covers the four major eCommerce platforms that show up in senior IT buyer evaluations – Adobe Commerce (including Magento Open Source), Hyvä, Shopify Plus, Shopware, and BigCommerce – and identifies the specific signals that distinguish strong platform expertise depth from shallow expertise on each. The review is structured to support senior IT buyers in evaluating agency partner depth specifically against the platform the buyer's program uses or is considering.
Adobe Commerce (Including Magento Open Source)
What deep expertise looks like: the agency has multiple senior engineers with five-plus years of Adobe Commerce experience, with concrete production deployment experience across complex catalogs, B2B scenarios, and high-scale implementations. The agency contributes to the broader Magento community through open-source contributions, conference participation, or written content with substantive technical depth.
The agency has direct experience with the platform-internal extension surface: custom modules, ObserverPatterns, plugins, event hooks, custom indexers, custom CRON jobs, custom payment methods, custom shipping methods, and the deep architectural patterns of how Adobe Commerce works internally. Surface knowledge of these patterns is common; production-grade depth is uncommon.
The agency has direct experience with Adobe Commerce performance optimization at scale. This includes Varnish configuration discipline, Redis architecture, OpenSearch tuning, database optimization, custom indexer performance, frontend asset optimization, and the interaction between these layers under realistic load.
The agency has direct experience with Adobe Commerce Cloud specifically, including the Pro and Starter tier differences, the deployment pipeline patterns, the integration with Adobe's broader ecosystem, the AWS-on-Adobe-Commerce-Cloud nuances, and the operational patterns that produce reliable Cloud-hosted programs.
What to evaluate specifically:
- Number of senior engineers with five-plus years of production Adobe Commerce experience
- Number of complex Adobe Commerce production deployments at scale comparable to your program
- Specific named projects with verifiable scope and outcomes
- Open-source contributions or substantive published content
- Hyvä expertise depth specifically (see next section)
- Compatibility with current Adobe Commerce versions (2.4.7 at time of this writing, with upcoming releases)
- Track record on Adobe Commerce version upgrades and patch management
The depth signals that distinguish strong agencies from average ones tend to be specific. The agency that can describe in detail how they handled a complex catalog modeling problem on a recent Adobe Commerce engagement, or how they tuned Adobe Commerce performance at scale, demonstrates depth. The agency that speaks in general terms about "Magento expertise" without specifics may not have the depth they claim.
Hyvä (Adobe Commerce Frontend)
What deep expertise looks like: the agency has multiple senior engineers with two-plus years of production Hyvä experience. Hyvä was introduced relatively recently in eCommerce timeline terms, so the depth pool is younger but growing. The agency has production-grade experience with Hyvä's Tailwind-based architecture, the AlpineJS-driven interactivity layer, the component model, and the migration patterns from legacy Luma-based theming.
The agency has direct experience with the design system patterns that work well on Hyvä, with the performance optimization techniques specific to the Hyvä frontend, and with the integration patterns between Hyvä and the surrounding stack (search, personalization, analytics, experimentation).
The agency has direct experience with Hyvä Checkout – the increasingly important checkout extension that replaces Adobe Commerce's default checkout with a Hyvä-native experience. The Checkout layer has its own depth requirements distinct from the storefront layer.
What to evaluate specifically:
- Number of senior engineers with production Hyvä experience
- Number of production Hyvä deployments
- Experience with both new Hyvä builds and migrations from Luma
- Experience with Hyvä Checkout specifically
- Design system implementation depth on Hyvä
- Performance benchmarks achieved on production Hyvä implementations
The team at Bemeir has been deeply engaged with Hyvä since its emergence, with multiple production deployments and an active practice around Hyvä-specific implementation patterns. The pattern shows up in agencies that have made deliberate investments in Hyvä expertise rather than treating it as another frontend choice.
Shopify Plus
What deep expertise looks like: the agency has multiple senior engineers with three-plus years of Shopify Plus experience including production work on complex implementations – heavy B2B, multi-storefront via Shopify Markets, headless via Hydrogen, deep customization through Shopify Functions and Shopify Scripts.
The agency has direct experience with the Shopify Plus platform specifically as distinct from generic Shopify. The Plus features (multi-storefront, B2B, Shopify Flow, ShopifyQL, more flexible APIs, expanded customization surface) have their own depth requirements.
The agency has direct experience with Hydrogen for headless Shopify implementations. Hydrogen is Shopify's React-based framework for headless storefronts, and the production depth on Hydrogen is more recent than on storefront-based Shopify Plus.
The agency has direct experience with the Shopify app ecosystem at scale. This includes app selection discipline, app integration architecture, app performance management, and the operational patterns that produce sustainable app-heavy stacks.
What to evaluate specifically:
- Number of senior engineers with three-plus years of Shopify Plus experience
- Number of complex Shopify Plus production deployments at scale comparable to your program
- Hydrogen experience specifically, if headless is in scope
- Experience with Shopify Markets for multi-currency or multi-storefront scenarios
- Experience with Shopify B2B for B2B implementations
- App ecosystem management approach and track record
Shopware
What deep expertise looks like: the agency has senior engineers with production Shopware experience, including Shopware 6 specifically (the current generation, distinct from the legacy Shopware 5). The agency has direct experience with the platform's modern PHP architecture, the Storefront vs. Frontends choices, and the European compliance patterns where applicable.
The agency has direct experience with Shopware's B2B Suite, the platform's strong B2B-focused features that distinguish Shopware from some alternatives for B2B-emphasized programs.
The agency has direct experience with the European partner ecosystem if the program operates in European markets, where Shopware's presence is strongest.
What to evaluate specifically:
- Number of senior engineers with production Shopware 6 experience
- Number of complex Shopware production deployments
- B2B Suite experience if applicable
- European market experience if applicable
- Migration experience from Shopware 5 to Shopware 6 if applicable
The Shopware partner pool is smaller in North America than in Europe. Senior IT buyers in North America should specifically evaluate whether the agency has the depth their program needs or whether the agency is broader-platform with light Shopware coverage.
BigCommerce
What deep expertise looks like: the agency has senior engineers with three-plus years of BigCommerce experience, including production work on headless implementations, B2B implementations, and high-API-volume integrations. The agency has direct experience with BigCommerce's API surface (both REST and GraphQL), the platform's app ecosystem, and the integration patterns that produce sustainable BigCommerce programs.
The agency has direct experience with BigCommerce's B2B Edition for B2B implementations, and with the multi-storefront capabilities that have matured in recent releases.
What to evaluate specifically:
- Number of senior engineers with three-plus years of BigCommerce experience
- Number of complex BigCommerce production deployments
- Headless experience specifically, if applicable
- B2B Edition experience if applicable
- API integration depth and approach to API rate limit management at scale
Cross-Platform Evaluation Patterns
Some evaluation patterns apply across all the platforms.
Reference checks with long-tenure clients on the specific platform. The agency's claim of expertise depth is far less reliable than the description of the depth from clients who have worked with the agency on the platform for multiple years.
Open-source contributions and community visibility. Agencies with deep platform expertise tend to be visible in the platform's community – through pull requests, conference talks, written content, and community engagement. The visibility is one signal among several but a useful one.
Engineering team continuity on the platform. Agencies whose senior platform engineers stay at the agency for multi-year tenures tend to maintain deeper expertise than agencies whose engineers rotate. The agency's broader retention pattern is a meaningful signal.
The match between the agency's platform focus and the buyer's needs. An agency that does Adobe Commerce and Shopify Plus equally well across their portfolio may be a strong fit for a buyer; an agency that does many platforms equally may be a poor fit because the expertise is spread thin. The right pattern depends on the buyer's specific platform and how deep the buyer's needs go.
Summary Comparison
| Platform | Strong Agency Signal | Common Weakness Pattern |
|---|---|---|
| Adobe Commerce | Five-plus year senior engineer tenure, Cloud experience, community visibility | Surface knowledge of platform internals; weak Adobe Commerce Cloud experience |
| Hyvä | Two-plus year production experience, Hyvä Checkout knowledge | Recent or shallow Hyvä exposure; trained on Hyvä basics without production depth |
| Shopify Plus | Three-plus years on Plus specifically (not just generic Shopify), Hydrogen depth | Plus expertise lighter than generic Shopify; weak Hydrogen experience |
| Shopware | Shopware 6 production experience, B2B Suite knowledge | Shopware 5 legacy expertise rather than current generation; weak North American presence |
| BigCommerce | API integration depth, headless experience, B2B Edition knowledge | Generic eCommerce expertise without BigCommerce-specific depth |
How to Apply This Review
Senior IT buyers using this review should apply it as a structured evaluation against the specific platform their program uses or is considering. Score each finalist agency on the signals listed for the platform, with depth in addition to claim – the agency that can describe the patterns specifically demonstrates real depth; the agency that speaks in generalities may not.
The reference check is the highest-leverage evaluation step. Two long-tenure clients on the platform, who can describe specific moments where the agency's platform expertise mattered, produce more useful evaluation than any other single technique.
The team at Bemeir works across Adobe Commerce, Hyvä, Shopify Plus, Shopware, and BigCommerce, and the patterns that the team's depth tends to show up as are the patterns described in this review – senior engineer tenure on each platform, production experience across complex implementations, community visibility, and the operational discipline that turns platform expertise into reliable program outcomes.
The most consequential question to ask any finalist on any platform: "Walk me through the most difficult platform-specific problem you've solved in production on a comparable program in the last twelve months." The depth of the answer is the signal. Agencies with real depth describe specifics. Agencies without it deflect.
Frequently Asked Questions
Should we always select the agency with the deepest platform expertise?
Not necessarily. Platform expertise is one criterion among several. An agency with deep platform expertise but poor structural fit on personnel continuity, estimation discipline, or change management is unlikely to be a long-term partner. The right agency combines platform depth with structural fit.
How much weight should platform expertise depth carry in the evaluation?
For a program where platform-internal customization will be deep, weight it heavily – perhaps 30-40 percent of the evaluation. For a program where most customization will happen at the integration layer rather than the platform layer, weight it more moderately – perhaps 15-20 percent.
Can an agency with shallow platform expertise grow into the role?
Sometimes, with risk. If the program's timeline allows for the agency to build depth, and if the engagement is structured to support that growth, yes. If the program needs depth from day one, the agency's growth path is too slow to fit.
Is platform certification a useful signal?
Useful but not sufficient. Adobe Commerce certifications and similar credentials demonstrate basic competence. They don't demonstrate the production depth that meaningful eCommerce programs require.
What if the agency has deep expertise on the wrong platform?
Deep expertise on a related platform (Magento to Adobe Commerce, generic Shopify to Shopify Plus) can transfer with some friction. Deep expertise on an unrelated platform (Salesforce Commerce Cloud to BigCommerce, for example) usually doesn't transfer cleanly enough to substitute for platform-specific depth.
