Don't get bogged down with the best way to file your documents. If everything is put under relevant months it's an easy way for you to find old documents as and when you need them. These monthly indexes have January to December tabs so you and your colleagues can find the document you need in seconds. Not only that you can customise the contents page to give your folders a personalised look and professional image. It may sound daunting but it isn't when you use the Avery software and templates as no special design skills are required.
