When manufacturers involve us
When your digital services can't keep pace with your products and customers
As your product range, customer base and partner network grow, existing portals and applications can become harder to use and extend. Customers still rely on manual support, partners work across disconnected systems, and new digital capabilities take too much effort to introduce.
Customer self-service isn't keeping up
Customers still contact your teams for routine requests and order status, while product knowledge sits scattered across manuals and systems. You need self-service that handles the routine and keeps complex cases with your people.
Dealers and partners work across disconnected systems
Partners need different information, permissions and workflows. Multiple portals, manual handovers and inconsistent processes get harder to manage as your network grows.
Your connected products have outgrown their apps
Your equipment and services are evolving, but customer and partner applications haven’t kept pace. You need new interfaces and workflows without starting again from scratch.
What we build
Digital services built around your customers and partners
We improve customer and partner services using the systems you already have. Where standard platforms can’t support the product-specific experience, business rules or integrations you need, we design and engineer what is missing.
Customer and partner self-service portals
B2B and OEM portals for equipment registration, service requests, warranties, spare-parts inquiries, product configuration, quotations and orders. Connected to existing customer accounts and business systems.
Installer and service-partner applications
Applications for equipment commissioning, configuration, diagnostics and maintenance. Integrate connected equipment, service information and the tools partners use in the field.
Connected-equipment apps and remote services
Customer and operator applications for remote monitoring, control, configuration and equipment information, integrated with existing device-cloud platforms.
AI-powered knowledge and service tools
Help customers, technicians and service teams find reliable answers across technical documentation, equipment information and business systems. We build AI assistants and workflow tools into existing portals and applications, with source references, appropriate access controls and human oversight.
Digital services we've built
Connected apps, partner tools and self-service platforms
Two industrial examples from Stiebel Eltron, and one cross-industry portal.
Stiebel Eltron · installer network
Servicewelt: digital tools for installers
Installers and service partners needed to configure, commission and troubleshoot increasingly software-enabled equipment. We built Servicewelt, a mobile app with device diagnostics, service history and configuration over cloud and local connectivity, reusing components from the MyStiebel platform.
Stiebel Eltron · heat pump owners
MyStiebel: a connected app for homeowners
Homeowners wanted intuitive remote access to their heat pumps. We designed and built the MyStiebel app and its integrations for monitoring and managing heating, cooling and hot water. MyStiebel and its backend achieved the highest possible score in the digital services category of Stiftung Warentest’s heat pump test (10/2025).
Nordic telecom · cross-industry
Complex B2B self-service at scale
For a Nordic telecommunications provider, we developed a B2B self-service portal handling complex customer accounts, subscriptions and transactions. The platform integrates with existing business systems and serves over 15,000 unique users monthly.
How we build
The engineering behind durable digital services
Digital services for industrial OEMs depend on more than the interface. A customer portal must connect to order and billing systems; a connected-equipment app needs reliable device-cloud data; and partner tools must reflect real service workflows.
We engineer the applications, integrations and underlying platforms together, so the service works in practice, not just on screen.
Engineering approach
Architecture decisions
Choosing the right patterns for each service: which parts to build, which existing systems to integrate, how to connect to the product and how the layers evolve as the business changes.
AI-assisted engineering
We use approved AI-assisted development tools to support software engineering. Our engineers remain responsible for architecture, code quality and delivery decisions, with human review, verification and safeguards for customer data and intellectual property.
Verification and release practices
Automated testing, release pipelines, monitoring and the engineering safeguards that keep services reliable in production.
User validation and product discovery
Research, service design and UX/UI practice that validate assumptions early and turn customer, dealer and service workflows into usable digital products.
Selected technologies: React · TypeScript · Java · Spring · PostgreSQL · Microsoft Azure · AWS · Kubernetes.
Why Proekspert
One engineering partner across the digital service
We’ve built industrial software since 1993. Our teams combine application development, connected-product engineering and enterprise integration, bringing the different parts of a digital service together.
Our delivered work spans connected applications for Stiebel Eltron and complex B2B self-service platforms. That experience matters when your digital service must work across products, customers and existing business systems.
When a digital service depends on reliable, consistent data from several systems, our data platform engineering provides the governed foundation and data APIs behind it.
How we work
Start with the workflow that needs to change
We don't assume you need a new portal. We start with the workflow and the systems already supporting it, then decide whether to improve the existing experience, extend it, or build what is missing.
-
Step 1
Understand the service problem
Where do customers or partners struggle? What still needs manual work? What has to change for the service to scale?
-
Step 2
Define experience and architecture
Workflows, roles, interfaces, business rules and integrations, and the architecture that fits them.
-
Step 3
Build and integrate
Apps, APIs, data connections and services for the selected workflow, with usability, security and maintainability designed in.
-
Step 4
Pilot and measure
Release to a pilot group and measure the result against the workflow you set out to change.
-
Step 5
Improve and extend
After release, we support the service and add functionality as your products, partners and business evolve.
FAQ
Common questions from industrial OEMs
Both. When a digital service requires product-specific functionality that standard platforms cannot provide, we engineer it. When an existing platform meets most requirements, we can configure, extend or integrate it. We assess the options before recommending an approach, considering functionality, integration needs, maintainability and long-term cost.
We work with the systems you already use, including ERP, CRM, PLM, FSM and device-cloud platforms. New customer-facing services can often be built around these systems without replacing them. Where legacy software is holding you back, we can plan staged modernization while preserving functionality that still works. Replacing everything isn’t the default.
We address security from the architecture stage, including identity and access management, role-based permissions, authenticated APIs and appropriate data isolation. The specific controls depend on the systems, data and risks involved. Proekspert’s information security management system is ISO/IEC 27001 certified, with project-specific security requirements defined during scoping.
A digital service may need account information from CRM, transactions from ERP, service records from FSM and operational data from a device cloud. These systems have different interfaces, access requirements and reliability constraints. We engineer the necessary APIs and integrations so they work together and remain maintainable as the underlying systems evolve.
We start by understanding the tasks and constraints of the people who will use the service. Depending on the project, that can involve user interviews, workflow mapping, prototyping and usability testing with customers, technicians, operators or dealers. The aim is to build digital services that fit real working conditions, rather than designing an interface in isolation.
Yes. Industrial OEMs often serve several user groups with different responsibilities, information needs and permissions. We design role-specific workflows and access controls for equipment owners, operators, dealers, installers, service partners and internal teams. These experiences can share a platform where appropriate, while giving each group the functionality and information they need.
Look for relevant delivery experience, not just a broad technology portfolio. Has the partner built complex digital services for industrial products or similarly demanding environments? Can they engineer the applications, integrations and connected-product services your project requires? Can they extend or modernize existing systems rather than insist on replacement? And can they support the service as your products, customers and business systems evolve?
