Final answer:
To send a payment link through Square, log in to your dashboard, create a checkout link, and share the link with your customer via email, text, or social media.
Step-by-step explanation:
To send a payment link through Square, you first need to log in to your Square Dashboard. Once logged in, navigate to the 'Online' section and then click on 'Checkout Links'. Here, you'll have the option to create a new checkout link. After setting up the link with the necessary details, such as the amount to be paid, description, and the item being sold, you can then save it. Once the link is created, Square will provide you with an option to share the link. You can send this link to your customer through email, text, or by embedding it on your website or social media pages. When the customer clicks on this link, they will be taken to a secure checkout page where they can complete the payment.
