Hello, I am interested in ways companies control the collection and archiving of material certificates. I am involved in a new company that is requiring all designated purchased materials have either a CofC or CofA available. We have only maintained a small collection of CofA`s in the past that fit in a few binders; the new requirement will result in a much larger collection. So far I am receiving some via e-mail and some as hard copies. Will you share how this is accomplished in your company? Thanks.
