Ask HN: Which document management system with OCR do you use?

I am looking for a way to get rid of my manual papertwork and ideally I am looking for some nice scan-workflow-engine, where I can scan my documents, run them through OCR, manually tag them appropiately and store the documents somewhere on a NAS. It would also be nice if I can integrate accounting in this solution. Since I am probably not alone with this I am just curious what others do.
