Paper organization is always a challenge/struggle. I have a couple of thoughts to consider in addition to trying to "cloudify" your records, since not all agencies accept printed copies of cloud records.
First look at a professsional report portfolio. Basically the same as a poly 2 pocket folder with a number of sheet protector type pockets inside with ability to label. Different colors help keep individual records, or provider or pharmacy separate from the others. Similar to expanding envelopes but easier to see what is there and more portable.
You ca also buy smaller planner sized binders, Enter pockets, protectors, envelopes as you prefer and keep them that way. You can use a section for new unfiled or not yet entered into the cloud and then put them into the section you prefer. That way depending on who is receiving services, you put the new receipts into a "catch all" in their folder/book, they don't fly around the home and are together for organizing when you have time to sit and get it done
Just a thought or two...
