E-claims will never be the only way of submiting claims. As matter of fact, unless you are on handwritten repair orders or are a claims processing company, you should avoid entering claims via the Internet and/or Dealerworld at all costs.
E-claims have absolutley no integration with your dealership's DSP (e.g. ADP and Reynolds), so claims submitted this way could create a nightmare for your accounting department (or you).
The e-claim system should be avialable for all GM dealers at this time. But, it should only be used in the case that your DSP went down and claims could not be processed. If this was the case, claims would be paid with the possibility that they were not posted through your system and many adjustments would have to be made.
My recommendation would be to go in and look at the system, but do not enter claims. To access the system go to
http://www.gm-dealerworld.com or get it through Access. You will have to enter your Autopartners password and I.D. (the same one you use for GMVIS).
On the other hand, hand written dealers need to get moving on this. DCS will see its last day on July 3rd. The format for processing claims (e.g. DCS printouts) is much different and takes some getting used to.
