Central Systems IT · Missouri
About Us
CSIT is a Kansas City IT & software shop — websites, the business software that runs behind them, and on-site support for Missouri and Kansas businesses. One login, one bill, one local shop, and real people who answer when it matters.
Small businesses deserve big-league technology
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.
No vendor lock-in, no mystery pricing, and no call centers. You own your site and your data — and you can take both with you. When it's hardware, we show up and install it on-site across Missouri and Kansas.
CSIT — Central Systems IT — is owner-built by John Vasquez. When you call, you talk to the person who builds it.

We spec, supply, and install the physical side. Security camera systems are designed to your building first — you see exactly what each camera covers before anything goes up — then we wire it clean, add networking, WiFi, point-to-point links between buildings, and access control, and install it on-site across Missouri and Kansas. After that we keep it monitored and supported.
