Good fit
This is for you if…
- Your team runs a core process out of spreadsheets, email threads or paper forms
- You pay for software that only covers half of what you need
- You want customers or members to self-serve instead of calling
- You have data in several places and need one tool that pulls it together

FAQ
Common questions
How much does a custom web app cost?
It depends on scope. A focused internal tool is very different from a multi-role portal. After a free discovery call you get a written scope and a fixed quote, so the price doesn’t change unless the scope does.
How long does it take?
Most first versions take 4 to 12 weeks. You get a live preview link early and see progress every week, not just at the end.
Do I own the code?
Yes. The code, the data and the accounts are yours. Everything is documented so another developer can pick it up if you ever need one.
Can you work with clients outside Wisconsin?
Yes. I meet in person around Kenosha, Milwaukee and Chicago, and work remotely with clients anywhere in the US.
