Once you hit any significant volume on Square, you can call them and move to a cost-plus rate.
2.4 mm annually is considered a small business? On what Planet? My experience says that's a very successful SB to say the least.
200k per month and not on Amazon? And your using Stripe/Square/Weebly and not getting InterX Plus? Tell me your website again..?
Considering rates, square is usable at 5k/mnth or below, avg ticket $10 or below. Now if you were laundering money square is great since they do 0 background checks. I'm looking at pizza joints in Brooklyn... you know who you are.
TLDR Square and weebly are terrible platforms for people that dont know any better. Ditto for Wix. I LOL IRL when someone says they use either of these platforms.
