well for the BOM it is only the list of materials you buy to build your robot. do not include the kit of parts.
i did the BOM for my team last year. I simply used excel and did a columns as follows- part description, number of pieces, cost per piece, final cost of pieces

if you need help or have any more questions pm me and I'll be gladly to help. I'm doing it for my team again this year.
