Featured Testimonials

  • "Now I can go into the part cost structure and see the direct overhead, variable overhead, direct labor all the way down—and I can see the formulas. We can look at these cost structures to find areas of profit or loss. Our old system could not get as granular as Plex. I suppose maybe we had a lot of data but no information. Now we are getting our information on a much more accurate level than it was before.”

  • "The Plex system prevents us from working on a part unless everything is set up properly, the correct raw material components are present, and all our inspections are done. I know it sounds simple and like it’s common sense, but it’s a big reason why we are not making the mistakes of our competitors."

  • "Before PLEX, various systems were used to achieve the company’s objectives in financial, process, and quality terms. Plex has generated a positive impact on the integration and visualization of the systems. I believe Plex will take the company to the next level globally."
