Web Apps for Processes That Off-the-Shelf Software Can't Cover.
Custom web applications for tasks that standard software can't handle. Customer portals, booking tools, internal utilities.
- starting price
- from €700
- to first version
- 3-4 weeks
- usable early
- In stages
If a process regularly eats up time, is error-prone or runs on spreadsheets and emails, a custom application pays off. We build modularly and deliver a usable version early, instead of developing for months behind closed doors.
What we build
Internal Tools
Tools for your own team: task management, time tracking, approval workflows, tailored to the actual work process.
Customer Portals
Protected areas for customers: document exchange, project overview, communication, everything in one place.
Booking Systems
Online appointment booking, resource management or reservation systems, integrated directly into the website.
Data Management
Structured capture, management and analysis of data, replacing spreadsheets and manual processes.
When it pays off
A custom web app rarely pays off from day one. Usually, the point has been reached when one of these sentences sounds familiar:
Three people maintain the same spreadsheet, and no one knows which version is correct.
Customers fill out PDF forms that someone then retypes by hand.
A standard tool can do almost everything, except the one thing that matters.
Recurring tasks cost hours every week that nobody has to spare.
Tools24: netztools24.de, vorlagentools24.de, pdftools24.de
Three independent tool platforms on a shared codebase: netztools24.de, vorlagentools24.de and pdftools24.de.

Frequently Asked Questions
When does a custom web app make sense?
As soon as a process regularly eats up time, is error-prone or is managed with spreadsheets and emails. When three people are maintaining the same spreadsheet or customers are filling out PDF forms, the point has been reached.
What does a web app cost?
A web app starts at €700. The exact price depends on the scope, from a clearly defined internal tool to a customer portal with integrations. For a binding quote, we need a short conversation about the specific use case.
How long does development take?
A lean internal tool can be ready in three to four weeks. Larger applications with user management, integrations and custom frontends take two to three months. We work in stages and deliver a usable version early on.
What technologies are used?
On the backend we use Laravel (PHP) or Python, on the frontend modern frameworks. The database is MySQL or PostgreSQL, depending on requirements. Hosting runs on our own servers in Germany.
Can the web app be extended later?
Yes, that is planned for. We build modularly so that new features, integrations or user roles can be added later without rebuilding everything.
How does support work after launch?
We fix bugs promptly. For further development and new features there are flexible arrangements, no mandatory maintenance contract, but reliable availability.
Can existing systems be connected?
Usually yes. Whether ERP, CRM, payment providers or custom APIs, we check the interfaces upfront and plan the integration from the start.
