Customer Portal for Multi-Country Partner Operations

About the client

The client is a Sweden-based B2B heat pump manufacturer operating across multiple European markets, requiring a scalable digital platform to support service partners, spare parts management, documentation access, and workflows.

The Story

The client engaged FiftyFive as a global software development and technology consulting partner to design, build, and scale a custom Customer Portal for multi-country partner operations. The objective was to replace manual, phone-driven workflows and fragmented legacy systems with a centralized, cloud-native platform owned and operated by the client. FiftyFive delivered the engagement as a full-cycle custom software development initiative, covering architecture, engineering, DevOps, QA automation, performance validation, and analytics. A dedicated cross-functional team worked closely with the client to ensure the platform could support regional expansion, localization, and high-traffic service operations.

Challenges

• > Phone-based ordering workflows with no digital transaction traceability.

• > Disparate legacy applications requiring separate installations and manual updates.

• > No centralized data model for spare parts, documentation, and software files.

• > Inconsistent workflows and routing logic across multiple countries.

• > Lack of automated testing, error reporting, and operational observability.

• > Unvalidated microservices behavior under regional configuration changes.

• > Performance and scalability risks during expansion to new markets.

The Solution

• > Designed and developed a custom microservices-based Customer Portal using React.js.

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

• > Built backend services and integrations aligned to client-owned domain workflows.

• > Deployed Kubernetes infrastructure with Azure DevOps CI/CD pipelines for automated releases.

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

• > Implemented parameterized, region-specific test execution for localization validation.

• > Configured cron-based error reporting integrated with Microsoft Teams webhooks.

• > Performed load and stress testing using Artillery to validate high-traffic readiness.

• > Integrated Microsoft Clarity for partner usage analytics and behavioral insights.

The Outcome

The Customer Portal achieved 60% service partner onboarding within the first year, exceeding the original 40% target and accelerating adoption across multiple regions. Automated workflows significantly reduced manual support dependency and eliminated phone-based ordering bottlenecks. QA automation lowered manual testing effort by over 60%, enabling faster, safer releases and reduced operational risk. Performance validation ensured stable operations during traffic spikes, supporting expansion into Germany, Finland, and 26 additional countries. The client gained a scalable, client-owned digital platform that improved partner experience, strengthened operational efficiency, and enabled confident multi-country growth powered by FiftyFive’s custom software engineering services.
