Custom workflow automation for more efficient business processes
Manual steps, scattered emails and spreadsheets slowing your processes down? We build custom workflow web apps that digitise, automate and monitor your business processes, from approval flows to complete order pipelines, fully tailored to how your organisation works.
Why a custom workflow web app?
Tools such as Zapier and Make are fine for simple automations. But once business logic becomes more complex, with conditional routing, multiple approval levels and integrations with legacy systems, they reach their limits. A custom workflow web app gives you full control over how your processes run.
Limitations of no-code tools
No-code automation tools are built for generic scenarios. With company-specific logic, strict compliance requirements or high volumes, you soon hit their limits: expensive per-action pricing, limited error handling, no complete audit trail and reliance on a third party for your core processes.
Benefits of your own system
With a custom-built web application, you set the rules yourself. Complex conditional logic, unlimited scalability, full integration with your IT landscape and ownership of your data. No vendor lock-in, no per-action costs and an interface that matches exactly how your team works.
Typical use cases for custom workflows
Organisations choose custom development when their processes don't fit a standard tool. Think of multi-step approval processes with shifting hierarchies, complex onboarding journeys dependent on external systems, or compliance flows where every step must be legally sound. See also our custom software development services for broader solutions.
Which workflows do we automate?
From internal operations to customer-facing processes, we build workflow web apps for a wide range of business processes. Below are the most common types we develop.
Approval flows
Multi-level approval processes for purchase orders, leave requests, budget requests or publications. With conditional routing based on amounts, departments or roles, and automatic escalation when delays occur.
Onboarding & offboarding
Structured employee journeys: creating accounts, assigning hardware, scheduling training, having contracts signed. Each step is automatically triggered by the previous one, with oversight for HR and the manager.
Document routing
Automatic classification, assignment and processing of incoming documents, from invoice processing to contract management, with versioning, approval and archiving in line with your retention policy.
Order processing
End-to-end order processing: from intake to delivery. Validation, stock checks, picking instructions, shipping labels and customer notifications, all in one automated flow that connects with your existing systems.
Incident management
Structured handling of incidents, complaints or reports: automatic prioritisation, assignment to the right team, SLA monitoring and escalation paths, with a complete audit trail for later analysis.
Compliance workflows
Processes that meet regulatory requirements: DPIA processes, internal audits, quality controls or certification procedures, with mandatory steps, evidence collection and automatic reports for regulators.
Core features of our workflow web apps
Every workflow web app we build includes a set of proven features that together ensure reliable, transparent process automation. We tailor the exact implementation to your situation.
Visual workflow builder
A clear interface in which your team can view and manage workflows. Steps, conditions and routes are shown visually, so process owners immediately understand how a flow works, without any technical knowledge.
- Drag-and-drop steps and connections
- Visual status for each active case
- Version control of flow definitions
Conditional logic and routing
Complex business rules translated into automated decisions. If/else conditions, parallel paths, time-based triggers and dynamic assignment based on roles, departments or arbitrary data attributes.
- Unlimited nesting of conditions
- Parallel and sequential paths
- Dynamic assignment based on rules
Notifications & escalations
Automatic alerts via email, Slack, Teams or push notifications at every relevant moment. Deadline monitoring with automatic escalation to managers when steps stall for too long.
- Multi-channel notifications
- SLA timers and deadline monitoring
- Configurable escalation ladders
Reporting & audit trail
Full record of who did what and when. Dashboards that make bottlenecks, processing times and volumes visible. Exportable audit logs for compliance and internal accountability.
- Real-time process dashboards
- Immutable audit log per case
- Automated compliance reporting
Integration with your existing systems
A workflow web app never stands alone. Its strength lies in its integration with the systems your organisation already uses. We build API integrations that connect your workflow seamlessly with your IT landscape.
CRM & ERP
Bidirectional integrations with systems such as Salesforce, HubSpot, Exact Online, SAP or Microsoft Dynamics. Workflows that trigger automatically on CRM events and write results back to your accounts.
Communication & collaboration
Integration with Slack, Microsoft Teams, email (SMTP/IMAP) and calendar systems. Assign tasks, request approvals and send status updates directly in the tools your team already uses.
Legacy & custom systems
Integrations with older systems via SOAP, FTP, database connectors or custom middleware. We also connect systems without a modern API so they become part of your automated flow.
Technology stack
We build our workflow web apps with proven technologies: React or Vue.js for the frontend, Node.js or Python for the backend engine, PostgreSQL for data storage, Redis for queuing and real-time events, and Temporal or similar orchestration frameworks for reliable workflow execution. Deployment via Docker and Kubernetes for scalability.

Audit and traceability
Every event in the workflow is logged in a tamper-proof way: who, what, when and from which IP address. These logs can be exported for internal audits, external regulators or ISO certification. Combined with version control on flow definitions, you always have full insight into the history of every process.
Frequently Asked Questions
The costs depend on the number of workflows, the complexity of the business logic, the number of integrations with external systems and the degree of customisation required in the UI. We work in phases, so you can start with the most important flow and expand gradually.
A first working version with the core flow is usually ready within a few weeks. Full implementation, including integrations and edge cases, takes several months, depending on the scope. We deliver in sprints so you can get started quickly.
Zapier and Make are excellent for simple point-to-point automations. A custom workflow web app is the better choice for complex conditional logic, high volumes, strict compliance requirements, or when you need full control over data and hosting.
Yes, integration with existing systems is a core part of our work. Through REST APIs, webhooks, database connectors or custom middleware, we connect with virtually any system, from modern SaaS platforms to legacy applications without a standard API.
We offer flexible hosting options: in the cloud (AWS, Azure or Google Cloud) with European data centres, on-premise at your organisation, or a hybrid solution. The choice depends on your security and compliance requirements.
After delivery, we offer maintenance contracts covering security updates, bug fixes and monitoring. Further development, such as new workflows, additional integrations and interface improvements, is planned based on your priorities and budget.
