Square Invoices

Square Invoices is a massively ubiquitous, fiercely frictionless, and deeply integrated platform that operates as a core pillar of the massive "Square Financial Ecosystem." While Square is famous for the little white credit card readers used by coffee shops, Square Invoices was built for businesses that do high-ticket work (like a caterer or a landscaper) who need to send a digital bill for $5,000 rather than swiping a card. The absolute core differentiator of Square Invoices is its "Native Payment Ecosystem and Frictionless Setup." You do not need to integrate a third-party payment gateway like Stripe or PayPal; the invoicing software *is* the payment processor. A caterer creates an invoice in the Square app, emails it, the client pays with a credit card, and the money instantly appears in the merchant's Square checking account. Because it requires absolutely zero technical setup, offers a completely free tier (you only pay standard credit card processing fees), and integrates flawlessly with Square POS and Square Payroll, it is the absolute default choice for local service businesses and retailers extending into B2B sales.
