A lot of people spend too much time taping receipts to 8.5" x 11" paper just to scan it and turn it in to a PDF to upload into an expense report system.
I don't know about you but I've got too much to do when I get back from a trip to have an arts and craft hour at my desk. Scanner Pro by Readdle is on sale during Christmas for $2.99. This will last until the 26th.
If you want to get really fancy with automation possibilities, and for FREE, go pickup Scanbot. Website
Either way, it will show you're far more capable than an 8 year old. It's time to start living in 2014 and create a PDF of your receipts as you make your purchases. I like both of these apps for this functionality and much more. You can't go wrong either way. Get both!
