Let’s try to break down point-of-sale systems in an effort to show you how easy and advantageous it is to use WordPress to manage your store.
Point-of-sale relies on the ability to log sales and take payments, the rest is kind of extra. Think of a cash register of the old school, people just had a cash register and a ledger. Nowadays we use the website as the ledger and connected to the “cash register” through scripting. This can be done through pretty much any web scripting language, as long as the payment processor that you using has an API to develop with it or you are willing to create one yourself, which could be very profitable if you could then sell it to the payment processor.
So to demystify point of sales online, with a basic store and WordPress and Woocommerce. Let’s think about it like this. You have a computer with a website on it, the website has your inventory inside of it fully, including stock. As a customer comes in to buy things, you can mark it on the screen and then mark their order as fulfilled as they have just paid you in cash. Now we can use the same system to accept payments online with the exact same website. The only difference is that we know that the fulfillment of the order happens through validation between your secure website in the payment processor, telling you when you have actually been paid. Once you have been paid you can then see that you have been paid, and then mark the order to be shipped out, or set a date for delivery, or set a date for pick up.
WooCommerce also has plugins for every sort of novelty, sales, gift cards, reward points systems. Every payment gateway you can think of, it’s really the answer if you need a simple to use point of sale system on top of a functional website and or blog.
