Here is what I do. I survived awhile on 200 GB of Google cloud storage that cost me $29.99 per year. Recently, I was getting close to 200 GB so I upgraded to the next level which was 2 TB for $99.99 per year. You can share this with up to five family members. Up until a few months ago, I was running dual cloud services as I also had Dropbox.
I organize my receipts as follows. I set up my folders like this.
I set up my file names like this.
This works fine for me
Regarding paperless as it pertains to text and notes, I have a huge Excel schedule with many tabs. I no longer write anything. No more pen and paper. It all goes into the Excel file. I never use it but you can search Excel using Control F. All my files are in the cloud so I can access on my desktop (my primary device), laptop (for when I travel), and my iphone.
Thus, the key is folder/subfolder naming and organization and having a file naming convention. There are probably 25 better ways to do what I am doing, but based on what I know how to do this is what I have come up with.
Have you ever tried Evernote?
I hope this helps, Thanks, Blake
