Your business processes as a web app — MVP in 8 weeks, scalable to 10,000 users
Custom SaaS solutions & dashboards
Tailored web applications, SaaS platforms, internal tools, and business dashboards — from MVP to scalable enterprise solution.
Anonymized Reference CaseLogistics service provider · Frankfurt, 110 employees+
Initial Situation
Excel-based order management, 3 full-time staff for data maintenance, no real-time visibility for customers, missing interfaces to freight forwarders.
Solution & Result
Custom web app: order management portal with customer login, real-time tracking, freight forwarder API integration, and automated reporting.
3 full-time positions freed for value-adding tasks, customer satisfaction +40%, 12 freight forwarders connected — all in one central platform.
Standard software never fits 100% — and forces your processes to adapt
- Every standard software has workflows that don't fit your industry — your team adapts to the software, not the other way around
- SaaS licenses: cheap for 10 users, expensive for 100, unaffordable for 500 — scaling costs explode with growth
- No interfaces to your specific systems: data exchange via export/import, manual transfer, errors, and lost time
Custom web app that maps exactly your process
- Built for your requirements: every workflow, every business rule, every interface exactly as you need it
- One-time development costs instead of eternal license fees — after 2–3 years custom software is cheaper than any SaaS
- API-first architecture: connect to any system that has an API — SAP, DATEV, accounting, logistics, CRM
Scope of Services
What Web Applications does for you
Business Dashboards
Interactive real-time dashboards for business data, KPIs, and operational management.
API Integration
Connection to REST APIs, GraphQL, third-party systems, and data sources for unified data views.
Authentication & Permissions
Robust user management with roles, permissions, SSO, and multi-factor authentication.
Cloud Deployment
Scalable deployment on AWS, Azure, or Vercel with automatic CI/CD pipelines.
Responsive & PWA
Cross-platform use — also installable offline as a Progressive Web App.
Scalability
From 10 to 10,000 users — scalable architecture for sustainable growth.
Our Approach
How we work
Discovery
Requirements workshops, user story mapping, and technical architecture decisions.
MVP Development
Rapid build of a Minimum Viable Product to validate core functions.
Iterative Development
Agile further development in two-week sprints with continuous user feedback.
Operations & Scaling
Monitoring, performance optimization, and scaling to growing requirements.
We freed 3 full-time positions from manual data maintenance. Colleagues now do tasks that are truly value-adding — and our customers see their order in real time. That was unthinkable with Excel.
MVP Approach
Live in 8 weeks —
with real users
An MVP significantly reduces risk: you validate the core concept with real users before fully investing. What works gets built out. What does not gets caught early.
Week 1–2
Discovery
Requirements workshop: core processes, user roles, user stories, technical constraints. Result: complete backlog and architecture decisions.
Week 3–4
Prototype
Clickable hi-fi prototype of all core features. Real users test and give feedback — before a single line of code is written.
Week 5–8
MVP Development
Agile development in 2-week sprints. Every week: working software on staging server. No progress report — you see real features.
Week 8
Launch
Deployment on cloud infrastructure, monitoring setup, user onboarding and documentation. You are live — with real users and real feedback.
Architecture
Scalable from day 1
We do not build prototypes that get thrown away later. The architecture scales from 10 to 10,000 users — without rebuilding.
React / Next.js Frontend
Fast, responsive user interface with TypeScript. Server-side rendering for SEO-relevant pages, client-side for interactive dashboards.
REST / GraphQL API
Clearly defined API layer separates frontend and backend. Every connection to third-party systems goes through this layer — clean and testable.
Auth & Role Management
JWT, OAuth2, SSO (Microsoft, Google) and fine-grained role model. Multi-tenant architecture for SaaS applications.
Cloud Deployment
Container-based deployment (Docker/Kubernetes) on AWS, Azure or US/EU data centers. Auto-scaling, zero-downtime updates.
Fixed-price offer within 5 business days after the workshop
Integrations
If it has an API, we connect it. No system stays isolated.
Frequently Asked Questions
Everything you need to know about Web Applications at a glance.
01What does a custom web application cost?+
An MVP with core functions starts at €20,000 fixed price. Complete business applications with multiple modules, user roles, and API integrations range from €50,000–150,000. After a free discovery workshop you receive a binding fixed-price offer within 5 business days.
02What is an MVP and why do you recommend it?+
An MVP (Minimum Viable Product) is the first working version with the most important core functions. You can use it to gain real users and collect real feedback — before developing further features. This significantly reduces risk: you build what is needed, not what you imagined.
03Which technologies do you use?+
Frontend: React or Next.js with TypeScript — fast, maintainable, scalable. Backend: Node.js, Python, or .NET depending on requirements. Database: PostgreSQL, MongoDB, or Supabase. Cloud: AWS, Azure, or Vercel. We choose the technology based on requirements, not trends.
04How do you ensure scalability?+
Cloud-native deployment from the start: horizontal scaling through containers (Docker/Kubernetes), auto-scaling at load peaks, CDN for static assets. We architect for 10x your current volume — no rebuild when growth arrives.
05Can you integrate existing systems?+
Yes — API integration is standard in every web app. SAP, DATEV, Salesforce, HubSpot, Shopify, custom databases: if it has an API, we connect it. For legacy systems without an API we develop secure database adapters.
06Who maintains the app after launch?+
We offer SLA-based support: critical errors <4h, standard bugs <24h. Hosting monitoring 24/7 with automatic alerts. Ongoing development in running sprints per your roadmap. You receive complete documentation and source code handover — no vendor lock-in.
Free Assessment Workshop — no commitment
In 60 minutes we analyze your current situation and show you concretely which solution makes sense for your business — with a binding offer within 5 business days.
