Square is ideal for a founder selling in the real world — markets, cafés, salons, pop-ups — because it bundles a free POS app, hardware, and payments with no monthly fee. Setup is fast and non-technical, and it includes tools for invoices, a basic online store, and receipts. You can take your first payment the same day.
