About us
Sentra CMS is made by Computer Systems Plus, Inc., a family-owned software company in Fresno, California, serving public agencies since 1990.
Software for the people who run local government
We’ve spent decades building software for clerks, councils and public works crews. Sentra CMS brings what we’ve learned to the place most residents meet their government first: the website.
- Family-owned and based in Fresno, California
- Serving public agencies since 1990
- Built and supported by the same team

Every resident can use their city’s website
Accessibility isn’t a feature we added; it’s the rule the product enforces. If a page can’t be used by someone with a disability, it shouldn’t be published — and with Sentra CMS, it can’t be.
- WCAG 2.1 AA enforced on every publish
- Plain language encouraged everywhere
- Emergency information that loads on any phone
