Creating a Square account is fast, easy, and, most importantly, free. To start, just head to squareup.com and click “Sign in” in the top right corner. Then, click “Sign up” and enter your email and desired password for your account. Once signed in, you will be directed to your Square dashboard. Once at your dashboard, on the left you can click on “Items” and edit the products you want to be made available by adding them to your inventory. You simply enter the product name, a description, an image, the price, and your stock of that item. If you’re looking to offer a service rather than a good, you can click on “Appointments” to allow your customers to book your services and pay online.
