Don't force your accountant to sift through a pile of paper receipts. Pixily is a new service that lets you store and share documents online. With the free version, users get 200 pages of storage, but all documents must be e-mailed to Pixily. For a fee, Pixily will send you prepaid envelopes or boxes so you can mail in your files. The company then scans and uploads the documents -- and encrypts them for security. Plans range from $4.95 a month for 1,000 pages of storage to $59.95 a month for 12,000 pages.
