It's basically old school double entry book keeping, except you've got ballots and votes cast instead of inventory and $. You start with empty ballots and the electoral list. You record every ballot that's used (or damaged) and every voter that shows up and casts a vote. You end up with a paper trail of everything that happened as well as every ballot. Every bit of the process is done by two employees+a polling station supervisor+party representatives (volunteers) making sure everything is done by the book. Everything should balance if there hasn't been fraud or mistakes. Counted ballots go in respective envelopes (for box 57 you'll have a liberal party, conservative party, green party, npd, invalid ballot, etc. envelop) allowing for swift recounting and making sure valid ballots for the right party are in every envelop.
