If I'm going to be at a client location for a few weeks I need to save every receipt I get then I need to invoice the entire lump. It's a mind-numbing process.

On my last trip I had 97 receipts, it was an absolute pain, luckily I had a 10 hour flight to do it over.

In a perfect world I'd take a photo and it would OCR what it can and then voice prompt me for notes. That way I could just snap a photo and speak into my phone something like "£37 for pints... I mean dinner at the Old Flaming Hen".

When it comes time to actually use these receipts then I could download the lot of them and send them off as part of my invoice.

A small but VERY nice feature would be giving the file names something relevant as normally I have to upload them one at a time. Instead of DCR0299.jpeg if they could be "01-17-2014 23:11 £37 for pints... I mean dinner at the Old Flaming Hen.jpeg" then they'd be much easier to find when accounting asks me questions.

I haven't seen much in this space, maybe I'm not looking in the right places or there isn't a very big market.
