John Finn, founder and CEO of Greenslate, remembers the good old days — and they weren’t that good. In 1995, when he first got into the independent film industry, he was a freelance production accountant, loaning himself out to productions where every penny counted. The standard practices of production accounting were daunting back then: there were seas of paperwork, year-end production company tax filings were strenuous efforts, and, on set, accountants would spend entire days running around just trying to get signatures on start paperwork from producers and crew members.
