I've been reading about this on their website.
Seems to me that if you want to try this out because it is difficult for you to keep track of receipts, then it's still going to be difficult for you to keep track of receipts for inputting into the scanner if you don't have the habit of going thru them regularly anyway.
If it's for the automated expense reporting and syncing with tax forms, then as long as it's 100% accurate (do you want to risk anything less with the IRS?), and requires no MORE of your time than putting the receipts in Quicken, or downloading your credit card statements into it, then it might be worth as much money as the cost of Quicken(or other systems).
I have my doubts as to the time effectiveness, simply because as someone else pointed out, receipts vary widely. If you have to scan the receipts, verify the results and correct them, then what advantage is it to you?
I'm not saying it might be just the thing for someone. But it's going to require the same committment and habit as any other system out there.
Just my thoughts, good luck with your decision.
