Questions, answered
What does CSIT actually do?
We build your website and give you the software that runs behind it — jobs, scheduling, customers, quotes, invoices, and e-signature — all under one login and one bill. The usual offer is $500 to build the site plus the Crew plan at $149/month for up to five people.
What is Permit Intelligence?
For the trades — roofing, HVAC, electrical, plumbing, general contractors — it puts the permit requirement in front of you before the truck rolls, not after.
I run a professional firm, not a trade. Is this for me?
Yes. For law, CPA, insurance, title, and dental offices we set up intake forms, secure document handling, e-signature, appointment requests, and a site clients take seriously.
Where do you provide on-site service?
We install and support on-site across Missouri and Kansas. Anything software — websites, hosting, tooling — we deliver anywhere. You talk to the person who built it.
Who owns my data and my site?
You do. No lock-in — you can take your site, your data, and your setup with you. We build things to be handed over, not held hostage.
Do you do security cameras and access control?
Yes — it's a core part of what we do. We design camera coverage to your specific building so you can see exactly what's covered before anything is installed, handle networking, WiFi, point-to-point links and access control, install it on-site across Missouri and Kansas, and keep it monitored.
Is there a free option?
Yes. A free Community plan is available for people who just want to look around first — forums, chat, and our developer tools, with no business tools.
One login. One bill. One local shop.
Talk to us about IT help, cameras or a website and the software to run behind it. Missouri and Kansas on-site; software anywhere — and you talk to the person who built it.
