I've been using Google Docs and Evernote to keep track of my CE's for a long time and I finally decided to give up using them because I wasn't satisfied with them. I've recently came across Unioncy (
www.unioncy.com), which automatically creates a digital inventory of all my belongings from the information in the receipts in my email. So I don't have to worry anymore about it, as it's created instantly. It seems quite useful to me. Hope someone can share their experiences with it!
