Just joined startup (automates expense reports), looking for feedback.

I just joined http://abukai.com on the sales side part time. I'm looking for any feedback on the start up or product. I think there's big opportunities for it. We automate expense reports by allowing you to take pictures of receipts with your mobile, and we use OCR to fill in your expense reports. The app is out on iphone but we're still working on BB and android.

Any feedback would be good, but I guess my questions are 1) would your company use this 2) who would this be most useful for 3) why you wouldn't use it.

Thanks,

Taige
