The first two programs I ever developed (and sold a few licenses for, thank goodness) were Church Secretary for Windows and Been There, Done That!
Yes, I am a Christian and developed Church Secretary for Windows as an alternative for many congregations that could not afford the much more expensive church management software that was available at the time. I was also working as an IT Specialist (Network Administrator/Server Administrator/Customer Support rolled in one) when I developed Been There, Done That! out of self defense. There was no budget for help desk software and I wrote my own program to help me do all the things my job involved. It may be that you are working in the Information Technology field and may have to provide support to end users, as well as keep track of hardware and software inventory and so on with no budget for expensive software.
Been There, Done That! 2015 is about to be released and it will be sold at the original price of $75. At least for a little while.
