I thought mm was a little overly meticulous when I first saw his receivables line item in his networth reports. Now I'm totally onboard! I added it to Quicken on Friday to track things like outstanding rebates, insurance claims, cash rewards and earnings that are owed to me, but not yet accessible.
I'm not sure when all of it will trickle in, but I figure I have about $400 of receivables right now and I like being able to see that as a part (albeit pending) of my cash flow. I do not intend to include this when I calculate net worth though.
