As soon as the election closes, every urn is opened in front of the randomly-selected citizen officials, and voluntary party witnesses. Votes are counted, including invalid/nulled votes, an electoral "acta" (a written record) is filled, everything is sealed and delivered to the National Electoral Institute (INE) local office. This happens mere hours after elections closed, and it is simultaneous in all urns. The INE gives preliminary results when they're statistically certain, usually the same night around 10-11pm. Even if the last percent of urns is delayed, they aren't enough numbers to affect the results, but anyway, the records get certified as they arrive, and the next day 100% of votes are accounted and the election is closed. The system is pretty amazing, mainly becaue the INE is an independent civil institution. Unfortunately, our current president is making every effort to subvert it and return to the times where the government ran the elections in opacity.
