Case Study Modernizing B2B Commerce with a Magento Upgrade
How we modernized a global B2B industrial systems provider's e-commerce platform with a Magento 2.4.7 upgrade and AWS auto-scaling.
The Client
A global manufacturing leader optimizing its digital commerce backbone.
The client is a prominent global B2B provider specializing in lifting, securing, and connecting systems. They manufacture high-strength industrial chains, steel wires, cargo control products, and heavy-duty rigging components that keep global supply chains moving safely. Operating under multiple regional brands with a extensive network of distributors, plant managers, and procurement officers, the client's main e-commerce website serves as the primary transaction engine and digital backbone for the entire group.
Operating in a complex B2B manufacturing landscape, the client must manage high volumes of traffic, customized pricing tiers, and diverse catalog configurations. Industrial buyers do not shop like typical B2C consumers; they place large bulk orders, require real-time product specification sheets, and expect pre-negotiated customer-specific contract rates. The system must remain highly available and performant to prevent any disruptions to time-sensitive industrial operations and supply agreements.
As their global customer base expanded, their legacy Magento e-commerce platform began to struggle under the load. It lacked the flexibility to integrate with their newer customer relationship management and enterprise resource planning systems. The corporate leadership team recognized that to secure their competitive edge, improve buyer experience, and eliminate operational vulnerabilities, they needed to execute a major technical upgrade of their core e-commerce infrastructure.
The Challenge
Legacy systems, security risks, and siloed data slowing global B2B commerce.
When we began this project, the client's digital storefront was running on an outdated Magento 2.3.5 setup. This version had reached its end-of-life, leaving the site exposed to security vulnerabilities and missing critical performance patches. The frontend experience was slow, relying on heavy, custom-coded legacy modules and themes that hindered page load speeds and provided a poor user experience on mobile devices.
Operational processes were also highly fragmented. Inventory, order details, and customer-specific contract pricing were managed in a separate SAP ERP database, but the integration with Magento was not real-time. This lag meant that customer accounts frequently displayed outdated inventory status or incorrect wholesale pricing, resulting in support team overhead and ordering delays. On the marketing side, lead generation and cart abandonment campaigns were handled manually because there was no direct connection between their HubSpot marketing platform and Magento storefront.
Outdated Magento 2.3.5 architecture lacked essential security and performance updates.
Heavy, legacy frontend modules slowed down site speed and mobile navigation.
Siloed SAP ERP databases resulted in lag times for customer-specific B2B pricing and stock levels.
Siloed marketing systems led to inefficient manual processes for tracking leads and cart recovery.
What our audit found
Tracing performance friction and API sync delays.
Our systems engineers conducted a comprehensive code audit and infrastructure review of the client's current setup. The diagnostic showed that the site latency was primarily caused by the accumulation of third-party Magento extensions that had been added over several years. Many of these modules were obsolete, poorly optimized, or conflicting with one another, resulting in excessive database queries and CPU spikes on the web servers.
Infrastructure analysis also revealed that the website was running on a single, fixed-capacity cloud instance. During peak business hours, when plant managers and wholesale buyers were actively browsing and placing orders, the server ran out of memory, causing transaction lag and temporary database connection errors. Furthermore, the integration pipelines with SAP and HubSpot were built on scheduled batch scripts rather than real-time webhooks, causing data out-of-sync windows of up to 12 hours. It was clear that the client needed a simplified codebase, an automated scaling hosting environment, and modern API integrations.
Legacy third-party extensions caused resource conflicts and page load slowdowns.
Fixed-capacity cloud architecture was unable to handle traffic surges during peak order hours.
Outdated batch-sync processes caused persistent data delays between e-commerce and ERP databases.
Redundant and slow frontend code blocks interfered with mobile responsive styling.
The Solution
How we turned it around.
Implement an AWS Auto-Scaling Hosting Infrastructure
We migrated the e-commerce storefront to a high-availability Amazon Web Services (AWS) environment. We configured an Elastic Load Balancer (ELB) combined with Auto Scaling Groups to distribute incoming web traffic dynamically across multiple EC2 instances. During traffic spikes, the hosting infrastructure automatically provisions new web servers to maintain fast page load times and scales back down during quiet periods to optimize hosting costs.
We also configured Amazon CloudWatch to provide real-time monitoring and alerting, ensuring that the engineering team is notified of any infrastructure anomalies before they affect users.
What we shipped
- Deployed AWS Elastic Load Balancing to distribute traffic across redundant servers.
- Established Auto Scaling Groups to automatically handle traffic fluctuations.
- Configured CloudWatch to monitor system resources and application logs in real-time.
Execute a Complete Magento 2.4.7 Upgrade and Code Cleanup
Our development team executed a full platform upgrade from Magento 2.3.5 to the modern Magento 2.4.7. We systematically reviewed the client's custom code and extensions, retiring outdated modules and replacing them with native Magento features or lightweight, modern alternatives. We rebuilt the frontend theme using the responsive Minimog e-commerce template, optimizing code delivery and asset compression to ensure fast loading speeds and smooth navigation on both desktop and mobile screens.
What we shipped
- Upgraded the core e-commerce engine to Magento 2.4.7 with all recent security patches.
- Removed outdated extensions, reducing database queries and system complexity.
- Rebuilt the frontend using the Minimog theme for an optimized mobile user experience.
Build Real-Time SAP and HubSpot Integrations
We developed and deployed secure, real-time integration pipelines connecting Magento to the client's SAP ERP and HubSpot marketing instances. The SAP connector syncs inventory status, wholesale pricing rules, customer account permissions, and order records instantly. The HubSpot integration automatically routes lead details, tracking user behavior, and triggers automated cart recovery emails when a customer abandons their checkout workflow.
What we shipped
- Developed real-time webhooks for immediate synchronization of customer pricing and stock levels with SAP.
- Connected HubSpot to automate lead capture, customer segment reporting, and cart recovery.
- Integrated GA4 Pro to provide deep analytics insights into user search and buying behavior.
The Numbers
Outcomes we can talk about.
The migration to the upgraded Magento 2.4.7 platform successfully modernized the client's global B2B digital commerce operations. By simplifying the codebase and leveraging AWS auto-scaling infrastructure, the organization eliminated system instability and established a fast, secure shopping experience. The mobile-friendly, modern UI has significantly elevated customer satisfaction among purchasing officers and plant managers.
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 engagement was measured qualitatively by the successful migration of active customer accounts, the elimination of page load lag, and the client's ability to handle high-traffic peak ordering windows without platform downtime.
With the new real-time SAP and HubSpot integrations actively syncing data, manual administrative oversight has been significantly reduced, allowing the client's marketing and sales teams to coordinate campaigns and track customer behavior with complete confidence.
What We Built
What's Next
Implementing advanced self-service portals and personalized recommendations.
Following the stabilization of the Magento 2.4.7 environment, the next phase of the partnership will focus on enhancing the customer portal. We plan to build advanced B2B self-service features, including quick-order templates, sub-account management for different facility locations, and automated request-for-quote (RFQ) workflows.
Additionally, we plan to implement Mageplaza's Auto Product Recommendation engine, utilizing first-party order history and browsing behavior to suggest relevant lifting and cargo control accessories directly to buyers during checkout.
