Ahmad Adil's Take: South Dakota's standard online processing is already fast enough that most founders genuinely don't need the $50 expedite option — about 1 business day is quick by any state's standard in this series. Save the extra fee unless you have a real same-day emergency. Once you're approved, the one detail worth writing down immediately is your anniversary month, since that's the anchor for every annual report going forward, and it's an easy thing to lose track of if you only remember "sometime last year."
