Now that the dust has started to settle around here, a bit, I thought I’d try my best to explain ACS in layman’s terms, who they are and why we think this acquisition is a match made in heaven between our two companies.

ACS are experts in helping companies solve complicated paper intensive business tasks. Okay, so you read that sentence and you’re SCREAMING… “ENGLISH, PLEASE?” Simply stated, ACS are “paper handlers”– not unlike airline baggage handlers. Now, before you jump to conclusions, just know I am making a radical oversimplification to help explain ACS.

You know what a baggage handler does – he or she takes your luggage and makes sure it gets on the right plane at the right time and doesn’t get broken (at least that is the idea).

ACS does the same for paper-intensive jobs, for example, processing health insurance forms. ACS takes paper and unstructured documents, like photos and hand-written notes and then processes, analyzes, stores and manages the information. Along the way it gets routed from place to place, making sure it doesn’t get lost and is readily available when needed.

To be sure, ACS does more than what I am describing here – but this is one area that got us particularly excited.

So how are ACS and Xerox a fit? Xerox is the world’s leader in document management and processing. Simply stated, we help companies deal with the vast amounts of paper being produced within their organizations , how they automate and interact with “documents” in the broadest sense of the word; be it paper or digitally-based.

We are going to be able to help ACS do a better job at paper handling; and they are going to help us present new ideas to our customers on how to design and manage some of the most complicated tasks they have – the ones that are still paper based.

I don’t know about you – but as we move forward, I think it makes for a very interesting way to handle baggage!
