Customer Portal

About the client

The client is a Sweden-based heat pump manufacturer serving B2B markets, aiming to modernize service operations by digitizing spare parts access, product documentation, troubleshooting workflows, and partner enablement processes.

The Story

The client sought a unified Customer Portal to eliminate manual processes, reduce reliance on phone-based ordering, and improve how service partners accessed parts, documentation, and software files. They partnered with FiftyFive Technologies as a custom software development and technology engineering provider to design, build, and deploy a scalable portal using a full-cycle development approach. A dedicated engineering team handled architecture design, development, DevOps, QA, deployment, and integration, ensuring the platform could operate reliably at scale and support future market expansion.

The Challenge

• > Manual ordering workflows dependent on phone calls and offline coordination.

• > Lack of centralized access to spare parts, alternatives, and reference documentation.

• > Fragmented systems requiring separate software installations and manual updates.

• > No structured communication path for automated error reporting and troubleshooting.

• > Increasing operational load due to rising service partner demand.

The solution

• > Built a custom Customer Portal using a microservices architecture with React.js frontend.

• > Developed GraphQL APIs integrated with PostgreSQL for structured spare parts and documentation data.

• > Deployed Kubernetes with Azure DevOps for automated CI/CD, scalable environments, and resilient releases.

• > Implemented automated testing using Jest and Cypress achieving 90% test coverage.

• > Configured cron-based error handling connected to Microsoft Teams incoming webhook alerts.

• > Integrated Microsoft Clarity for partner usage analytics and behavior tracking.

The outcome

The portal achieved 60% onboarding of service partners within the first year—exceeding the 40% adoption target and significantly reducing manual order-handling time. Automated workflows decreased dependency on phone support, improved spare parts discovery, and reduced operational inefficiencies. With a stable architecture and clear usage insights, the client gained a competitive advantage and is now expanding the platform into Germany, Finland, and 26 additional countries.
