I like questions and these are fascinating! It is not of question to monitor kashrus of business practices. If you are from Lita, check your old seforim by Chofetz Chaim: if it has “Muga” scribbled in pencil, that is because the author was personally checking that the books were printed and bound correctly. There are various organizations that check whether funds invest in illegal diamonds, child labor. some might do what these tzvei alter ice-screamers did – object to Israeli investments …
So, it might be possible to have a kashrus organization that checks the books and certifies them.
Need to know the standards though, maybe there will be:
gnivas israel heksher that allows over-charging non-Jews
tzvei dinim heksher – allows two sets of books, as long as both pass the kashrus separately
2-hand image heksher – given to those who shook hands with R Shimon bar Yochai
picture of an elderly Jew – to those who fully pay social security tax
hebrew national – certifies that you were not yet fined by IRS
1099 heksher – all employees working as contractors
