Square is a payment processing platform that handles transactions for small businesses, from card readers that plug into phones to full point-of-sale systems. If you're trying to understand how Square actually moves money—what happens when a customer swipes their card, how long settlement takes, what fees get charged—this is where to start. Square's tools sit between your customer's bank and your own, orchestrating the flow of funds across multiple systems.
The articles here explain the mechanics: how Square's different products work, what the payment timeline looks like from swipe to deposit, what costs are involved at each step, and how to read your settlement reports. You'll learn what happens behind the scenes when you process a payment, not just how to push the button.
