It is not computers that make things difficult, it is paper processes transferred 1:1 to digital ones. E.g. there is absolutely no reason you should even have invoices or bills as print-formatted things anymore, they should be machine readable documents automatically downloaded for you and presented in some summary for you in a unified appearance and you only need to drill down to individual ones if you want details. All of that is trivially possibly on a technical level, the hurdles are laws and people and incentives.
