I don't understand what you mean with prepare taxes.

I just add all purchases/sales right when they happen in my accounting app and attach the invoice PDF. Then when I have to file taxes, I export the correct numbers.

Are you doing your bookkeeping in Excel or something?

This is just for my personal taxes, no accounting involved. I just get all the relevant stuff together once a year. Of course it's not 10s of 100s of documents, but still enough so it would take me some time to get everything together manually.

Also it was just meant as an example, paperless is generally useful (to me) in situations where I need to access somehow related documents, like traveling and such, or searching my documents for some information. As I said, there are other systems and ways to do this, but for me this is the one that stuck.
