Customer Portal
Problem: Existing customers call or email to see quotes, orders, or invoices.
Solution: Portal with login, roles, quote approvals, order tracking. Next.js frontend, .NET backend, ERP integration via REST.
Software that fits your company, not the other way around. Full code ownership, GDPR-ready, hosted at Hetzner in Germany.
You get the code, the Git repository, and usage rights. No vendor lock-in, no pressure for follow-up contracts.
Fragon Cloud runs on Hetzner servers in Germany and Finland. No US CLOUD Act, GDPR-compliant under Art. 28.
You talk to the people who build your software. No call center, no project manager chain.
Transparent, agile, and goal-oriented to success.
We discuss your project and look at what you need. No hour-long workshops, just a focused conversation.
You get a clear quote with scope, timeline, and costs. We only promise what we can deliver.
We develop in weekly cycles and show progress in demos. You give feedback, we iterate.
We deploy on Fragon Cloud and train your team. Then you decide: maintenance contract or self-operation.
Four scenarios we see again and again. Not a complete list, but a sense of what custom software can look like.
Problem: Existing customers call or email to see quotes, orders, or invoices.
Solution: Portal with login, roles, quote approvals, order tracking. Next.js frontend, .NET backend, ERP integration via REST.
Problem: A team is stuck in Excel: duplicate data entry, email ping-pong, no audit trail.
Solution: Web application with roles, audit log, Excel import/export. Much smaller than an ERP, much more fitting than a standard solution.
Problem: Invoices arrive as PDFs; someone retypes them into the accounting system.
Solution: OCR, structured extraction, approval workflow, API integration with BMD or similar systems. Usually amortizes within a year.
Problem: The ERP covers 80 percent; the last 20 percent is done in Excel.
Solution: Dedicated application with ERP integration that covers the missing 20 percent. Data flows both ways, no double maintenance.
After the first conversation, you get a realistic estimate. The ranges below cover 90 percent of projects. What matters is not the number of screens, but how deep the integration with your existing systems goes.
