Automate the busywork that holds you back.
BusinessSysAI builds automations, chatbots and custom software for small businesses — so you can focus on customers, not paperwork.
Three ways to give you time back.
No off-the-shelf builder. Every solution is tailored to how you actually work.
Document automation
Quotes, invoices, contracts — created, filled in and filed automatically. No copy-paste, no forgotten line items.
AI chatbots
An assistant that answers customer questions around the clock, books appointments and captures leads — in English, German or Portuguese.
Custom software
When off-the-shelf tools don't fit: an application built around your exact workflow. Runs on your machine, everything belongs to you.
A complete quoting & invoicing app.
For my own contracting business I built an entire business suite: quotes, invoices, partial invoices, customer management, a product catalogue and PDF generation — trilingual. This isn't theory. It's in real, daily use.
From conversation to finished solution.
Conversation
We look at what costs you time every day. No obligation.
Analysis
I find the workflows that are actually worth automating.
Build
You get a finished solution — tested and ready to use.
