Right after I retired from the military I started work with a small business (8a) while I was also starting my own company. My contract stipulated I was to get 1% of any contracts I brought in and in the second month I was able to get a three year 70 million contract signed.
I never saw a penny because the owner said that since the office person filled out much of the standard paperwork, and that she attended a single meeting after the contract award, I did not bring in the contract on my own and thus was not able to get my 1%.
For that much I’d have taken him to court...likely gotten at least a portion of it.
