For the past couple decades or so i have been using a repair log i created, to keep serial numbers and logs of repairs.  Friends have asked me to make it usable for them. is a website i threw together with a trial download and overview.
If you are interested in evaluating it and offering suggestions let us know by filling out the contact us form on the

ShopDr.  Evolved from a need to track repairs on equipment. With the inability to return electronic parts when one is doing troubleshooting, the last thing a person can afford to do is buy something like an ignition module, only to realize you just replaced it last year and then not being able to return it.

By having the serial number handy and the service/parts department contact and the service manual exploded view all in one screen you can quickly get the parts and info you need.

Link cell phone pics or special tips or tricks used in the last repair to easily replicate the next time. 

Using an inexpensive barcode reader you can easily track your parts inventory / supplier / mfr so each oil change or repair has what you need on hand.
