To avoid clutter, consider storing as many of your paper records as possible electronically. This is possible through document scanning. It has a number of benefits as well, beyond the important one of decluttering your office. Once documents have been scanned they are electronically indexed for easy retrieval. Staff will be able to type in simple criteria in order to retrieve their documents and save a significant amount of time searching for replacing files.
Storing documents electronically is also much more secure as you are not at risk of losing documentation to an unexpected event such as fire or flood.
