The National Association of Professional Organizers announced its choice for The Best Business Organizing Product at this year's NAPO Conference. NeatReceipts is a digitized scanner that plugs right into your computer. You scan receipts, business cards, and documents into your computer. It will then organize them, using the key words on the receipts or documents. And then you can toss the paper!
NeatReceipts 3.0 version can turn your documents into PDF files. It will also search using keywords.
NeatReceipts is available at www.NeatReceipts.com, www.Staples.com, and other locations. The retail price is $229.99, but I found other websites offering it for less.
