Case Study Building Multi-Site B2B Commerce on Shared Magento
How we launched a multi-site Magento 2.4.7 storefront with real-time SAP integration and shared AWS infrastructure for an industrial supplier.
The Client
A global manufacturer of industrial components executing a multi-brand digital strategy.
The client is a leading global B2B supplier of industrial chains, mechanical drive components, and power transmission products. As a critical business unit under a larger manufacturing parent organization, they supply components that keep heavy machinery, assembly lines, and transport networks running. The parent organization was undergoing a comprehensive digital transformation to migrate its legacy systems, automate processes, and consolidate its diverse portfolio of brands onto a unified, modern web infrastructure.
In the heavy industrial components sector, B2B purchasing is highly complex. Buyers require access to extensive technical documentation, customized CAD drawings, and specific pricing agreements based on volume and contract terms. To serve this customer base efficiently, the client's storefront must handle large-scale database operations, complex business rules, and high transaction volumes while maintaining a clear and consistent brand identity that aligns with the parent company's digital standards.
To support this multi-brand strategy, the client needed to launch a new, dedicated B2B storefront. However, rather than building an isolated system, they wanted to leverage a multi-site Magento configuration to share resources, code, and infrastructure across multiple brands in the corporate group. This approach would allow them to control development costs, speed up times-to-market, and simplify long-term system maintenance.
The Challenge
Consolidating multi-brand e-commerce requirements on a shared system.
As the parent company's digital transformation advanced, the client faced the challenge of building a new B2B storefront that was fully integrated with their legacy systems but shared infrastructure with other corporate brands. They needed this new digital storefront to match the design language of their evolving parent portal, providing a consistent user experience for clients who purchase across different corporate business units.
Operationally, the storefront could not function as a standalone island. It required real-time data sync with their core SAP ERP database to handle live product configurations, customer-specific contract pricing, and automated order processing. Furthermore, the client needed to achieve this without incurring high software licensing, hosting, and engineering costs for each individual brand, making a shared, multi-site architecture and reusable code modules a critical business requirement.
Needed a new B2B storefront that integrated with a multi-brand Magento installation.
Required the storefront UI/UX to match the parent company's design system and portal.
Needed real-time SAP integration to support contract pricing and stock status.
Demanded a cost-effective hosting and maintenance model for launch and expansion.
What our audit found
Addressing the complexities of multi-site databases and ERP integration.
Our database and cloud architects evaluated the parent company's existing Magento environment and their SAP integration architecture. The diagnostic highlighted that running multiple independent storefronts on isolated cloud servers created high maintenance costs and significant database synchronization lag. When multiple instances attempted to query the SAP database simultaneously, it caused API bottlenecks and slowed down response times across all customer portals.
Additionally, the team discovered that legacy, brand-specific extensions made it difficult to upgrade the core platform or share codebase improvements. Every code change or security patch had to be manually tested and deployed across each site individually. To address these issues, the client needed a single, centralized Magento installation configured for multi-site operation, running on a shared AWS auto-scaling infrastructure, and utilizing standardized, reusable code modules that could support different catalogs and brand styles.
Independent hosting architectures created high operational costs and maintenance overhead.
Siloed database configurations prevented the sharing of catalog assets and code improvements.
Legacy API connections were vulnerable to performance bottlenecks during high-volume queries.
Lack of standard code modules delayed new brand onboarding and platform upgrades.
The Solution
How we turned it around.
Deploy a Shared AWS Hosting Architecture
We built a shared, high-availability hosting infrastructure on AWS to host the parent company's multi-site Magento environment. We utilized AWS Elastic Load Balancing (ELB) and Auto Scaling Groups to distribute incoming web traffic across redundant EC2 instances dynamically. By sharing this core infrastructure across multiple brand sites, the client minimized hosting costs while ensuring that each storefront can scale resources to handle global session peaks.
This shared foundation allows the corporate IT team to manage, monitor, and patch the core servers from a centralized command center.
What we shipped
- Configured a shared AWS auto-scaling stack to optimize multi-brand hosting costs.
- Deployed Elastic Load Balancing to distribute global traffic across redundant servers.
- Established a centralized monitoring framework to track performance across all storefronts.
Develop a Standalone Storefront on Multi-Site Magento 2.4.7
We created a standalone B2B storefront within the parent company's multi-site Magento 2.4.7 installation. We applied the Minimog theme, customized to align with the design guidelines of the parent portal, ensuring a fast, branded, and mobile-optimized customer experience. This multi-site setup allows the new storefront to run on its own unique catalog and business rules while sharing core code, extensions, and database resources with other brands in the group.
What we shipped
- Deployed the B2B storefront on a unified Magento 2.4.7 instance.
- Applied a customized Minimog theme optimized for mobile responsiveness and speed.
- Maintained unique catalog controls and business logic on a shared database.
Build Real-Time SAP and Ecosystem Integrations
We developed and integrated real-time synchronization pipelines between the Magento storefront and the client's SAP ERP database. This integration ensures that product listings, customized contract pricing, stock status, and sales orders sync instantly as transactions occur. We also configured and activated key marketing and customer support modules, including Mailchimp for automated campaigns, Tawk.to for live support, and GA4 Pro for deep analytics tracking.
What we shipped
- Integrated Magento with SAP ERP for real-time inventory and pricing sync.
- Activated Mailchimp to automate customer newsletters and segment communications.
- Configured GA4 Pro and Tawk.to to provide analytics and live support.
The Numbers
Outcomes we can talk about.
The launch of the new B2B storefront on a shared Magento 2.4.7 architecture successfully modernized the client's digital e-commerce operations. By utilizing shared AWS infrastructure and reusable code modules, the parent company significantly cut development and hosting costs per brand. The mobile-responsive, customized design has improved customer satisfaction, ensuring that industrial buyers can place complex orders quickly on any device.
Note on Metrics: Due to the client's strict B2B security guidelines and corporate data policies, quantitative performance metrics were restricted from public release. The success of the project was measured qualitatively by the successful launch of the new storefront, the integration of real-time SAP workflows, and the ease of onboarding future brands onto the shared infrastructure.
With the new real-time SAP integration actively handling complex B2B transactions, the operational team has eliminated manual order processing errors, allowing them to scale their multi-brand digital strategy with complete confidence.
What We Built
What's Next
Onboarding additional corporate brands and launching customer portals.
With the multi-site Magento 2.4.7 foundation established and performing stably, the parent company's digital roadmap focuses on onboarding their remaining brand portals onto the shared AWS infrastructure. This will allow them to consolidate their entire digital e-commerce footprint onto a single platform.
Additionally, the client plans to build advanced customer portal features, including quick-order forms for bulk industrial parts, sub-account management for corporate clients, and automated reorder triggers based on historical purchase schedules.
