The cost of on-site document storage for a company that stores around 50 boxes of paper per year is estimated at $150,000, annually. This number includes the cost of paper, the filing cabinets and physical space required, as well as labor. The cost of digital document storage is but a small fraction of this. Exact cost of digital document storage depends on many aspects. Above all, the number of users who need access to the digital files, along with the unique needs of different companies and the capability of the system. This in turn could encompass factors like flow of documents, indexing, redaction, retrievals of documents by keywords and process for creating new documents. The cost would also depend on the size (in GB) of the storage required.
