From practice
Typical use cases
Typical problems and solutions from projects with trades businesses and property management firms — written from the perspective of the respective clients.
HandwerkI used to write quotes at the kitchen table in the evenings. Since the software went live, I enter volumes and materials and the quote is out in ten minutes. What won me over: Mario builds nothing you don't need. No twenty modules, only what we actually use.
ImmobilienOur biggest issue was tenant requests coming in via email, phone and WhatsApp in parallel. With the portal everything runs in one place, tickets are documented, and I see at a glance what's open. Previous offers from larger agencies were three times as expensive and would have taken four months — with Mario we went live in six weeks.
KMUWhat would have been two weeks of meetings at an agency we sorted out with Mario in one conversation. He has access to the code, the server, to me. If I flag something on Friday, the adjustment usually ships by Monday. For us as a family business, that's the decisive difference.
Demos
Four industries, four web apps
No login, no signup – try them live. This is how I work: real software for real scenarios.
Questions
What you want to know
The most common questions from trades businesses and property managers before our first call.
You talk directly to the developer writing the code. No project managers, no sales layer. That saves weeks of lead time and 30-50% agency mark-up.
Typically within a few days. A short discovery call is enough to check fit. Then you get a quote, and on approval we start.
No pure WordPress sites, no mass e-commerce stores on standard shop systems, no crypto/NFT projects. The focus is custom software for operational SME processes.
