Free means the accounting; payments and payroll are charged, and that is where the business model actually is. Pro mostly buys away the $0.60 per-transaction fee rather than features, so on annual billing it only starts paying for itself somewhere above roughly 26 card transactions a month. Light on AI compared with the rest of this list.
