Create an Invoice

The Invoices API can be used to create an invoice to request payment for an order. The integration of the Invoices API into the applications can help sellers manage invoices efficiently. This, in turn reduces the development cost in the following ways:

• All invoices require an order ID and customer ID, which allows built-in integration with the Orders API and Customers API.
• Square follows up with customers for the invoices we create so that we don’t need to send them reminders or receipts.
• Square generates and hosts a web page where customers can pay the invoice at their ease.
