I did this quite a while ago. I now need to update it since a lot of things have changed. Not exactly looking forward to it, but needs to be done. I took pictures of all the tools and numbers. Now I just need to make some type of database and enter in all the information. I have a separate inventory I keep and updated for all the wood, hardware and consumables. For the second inventory I use quick books, it also tracks sales , purchased and all the tax related information.
