What is Square?
Hi there, I’m Kouta Shimizu, a web director. In this article, I’ll introduce Square, a versatile payment platform designed for both in-person and online sales.
Square is particularly convenient for those who need to manage both physical and online transactions.
Personally, I currently use Square for selling agricultural products.

Square is a payment platform tailored mainly for small and medium-sized businesses. It supports credit card payments and offers POS (Point of Sale) systems that can be easily set up using tablets or smartphones.
Founded in 2009 and headquartered in San Francisco, California, Block, Inc. has expanded into various financial services.
One of Square’s key features is the ability to easily start accepting credit card payments and cost-effectively build a POS system.
In 2018, Square acquired Weebly, a web hosting and site-building platform, integrating online store functionality into its offerings.
This service, known as Square Online, provides features like delivery orders and in-store pickup payments.

Square’s key feature is its ability to leverage the strengths of both physical store and online payment solutions.
