You forgot to mention Print document first, as these should be on the PC already. If you're dealing with paper forms, you have other issues to fix as well.
4. Use a Service management type tool. i.e. a web site.
Launch browser, log in, click upload, select document done.
No need to scan in, as document should already be in electronic form, and process should be fully traceable (no paper receipt needed).
