A place for everything and everything in its place - right! Most people pile things up as they come into their small business home office. I know I do.
Is this a time management issue? Just too busy to do anything but set the piece of paper down somewhere. Or is it a space and place management issue? Probably both.
The perfect time to organize your small business @ home office system for storing paper documents is at the start up stage. If that's already come and gone. Decide to start up again.
One technique for avoiding a start up pile up is to base your paper handing system on the purpose of the document. What does the information the document contains relate to - marketing, finance, personnel, etc. You may want to have a sub-category of type of document. File it accordingly.
Create your start up document filing system around business function not the document form so you can file it not pile it.
