Sounds like you’re pretty much set. For cash, I’d recommend taking no less than $100 for change, mostly a mix of $1, $5, and $10. It’s been a few years since I was a vendor, but it always seemed like I needed a lot of small bills to start. Still a fair amount of folks doing cash purchase, but the card swiper will give you a lot more flexibility for those who don’t carry cash, especially for larger purchases.
