Organizing finances and assigning a number to each record type
Mint.com does a pretty good job at this, for a free service, but it's mostly for personal finance. It looks at all of your transactions and tries to categorize them, and also allows you to create your own categories and filters. For example, when I started using it, it imported the last three months of my transactions and detected all of my 'coffee house' transactions. This is how I learned that I was spending about $90 a month going to Starbucks, rather than the $30 I had estimated.  I know it's not a 'system' like an accounting outfit might use, but most accounting offices I've worked with have had their own home-brewed system.
