That's not a terrible conclusion. Square loses money on lots of transactions (small ones--under ~$8 and they're losing money). Credit card processing involves a per-transaction fee which really adds up for small purchases and Square's pricing doesn't have a minimum or a per transaction fee.

Then there are things like Square Cash that make no business sense (there's no revenue, only expenses and risk). Great for consumers while it lasts though.

CC merchants are not supposed to ask a minimum CC charge. Call the merchant and complain, they have to take a one cent sale or a million dollar sale.

That's not true anymore for under $10 transactions (see Dodd Frank), but the point was that since Square has no minimum fee they actually lose money on small transactions. Square is used a ton for these sort of small transactions which goes a ways to explain why they have never made a profit (but have billions in revenue).
