Square Invoices

Square Invoices is a free invoicing tool that integrates with Square's payment network, so clients can pay invoices directly through ACH transfer or credit card without leaving the invoice. It handles recurring invoices automatically and sends payment reminders on a schedule you set.

It's well-suited to freelancers and small service providers who want to reduce unpaid invoices and collect faster without adding another subscription. The main limitation is that it's built primarily around Square's payments, so it works best if you're already using Square for point-of-sale or payment processing.
