I actually care less about bills and more about properly indexing my documents.

I'm still on my way to have a proper document management solution for my needs, so that I can retrieve any correspondence of the last X years.

Finding an apartment contract or some other important mail is worth more than just being able to pay the bills "automatically" - since you sort of can already do that with eBill or the QR Bills.

OCRing everything is the first step towards this goal :)
