Wow, Rob! Amazing system. I just have one tickler file but I have a spreadsheet that I complete each month when Bill writing... Each item is dated so I know what to expect for each month or what to pull out of tickler file. For example, I pay an irrigation fee twice a year so that item says "Next due date: 11/20) when I sit down to write Novembers bills, I pull out the irrigation invoice. Etc. Whatever works!
I designed an an inventory spreadsheet for one of hubbie's collections. Lists all the details of item and current value. Should anything, God forbid, happen to hubbie, this will be so helpful...and, of course, work is backed up on USB drive and will be updated as time goes on... This is a relief to complete..
