About J&I Services
J&I Services is two people who design and build software for businesses anywhere — websites, online stores, and apps for iPhone and Mac. We're based in Sedalia, Missouri, and work with clients remotely, wherever they are.
We ship constantly. Client stores take orders and send shipping labels every day, and since July we've built fifteen free working mockups for small businesses. The work on this site is all live — click any of it.
You talk to the people doing the work. No account manager relaying your feedback to a designer who relays it to a developer. Send a note, the change gets made, you see it on a live link — usually the same day.
