It's not small for a business starting on Weebly. That was my point above. Weebly isn't where a business doing $2.4m in annual online revenue goes for a website. They have a team, or at least a person or contractor, responsible for building the website and ecommerce.
All of my comments above were about the cottage industry where Weebly shines. There's a whole bunch of people making a little bit of money online...they aren't big clients for Square, but in aggregate they add up, and some of them will grow and Square will keep them as customers as long as they provide paths for growth.
I think there's just a breakdown in what kinds of business we're talking about in this conversation. Yes, in many segments, $2.4m annual is a small business (it's well under 50 employees, probably well under 25 employees). But, as businesses with their sites on Weebly go, it's pretty big. Weebly has always been a place to go for a first website, particularly for non-technical businesses...it's just not the place you go when you're building a multimillion dollar business.
So, both things can be true: $2.4m annual revenue is a relatively small business, and most businesses on Weebly will never grow to that size.
