A point of sales system is an alternative to a cash register. It records sales and transactions, accepts debit cards and credit cards. They have also evolved over time to track inventory, employee work hours and customer data. Following is a list of online and retail POS systems that integrate with the Shopify Platform.
Vend Point-of-Sale
Vend is a web based POS and stock management system you will love to use.
Vend works just like your current point-of-sale, but, because it is online pos software and runs in a web browser, it works on any computer, including an iPad, anywhere in the world. It even keeps working in offline mode, if you lose your internet connection.
MerchantOS is a powerful web-based point of sale and inventory control system. It keeps track of all your sales, customers, inventory, purchase orders, work orders, and more. It's got all the features you'll need to manage your brick and mortar retail business packaged in an easy to use and intuitive design.
Shopify Outlet is a point-of-sales software. You can create invoices for selling or purchasing products of your retail store. If you have a online shopify store and want to sell your products in offline too, this software will help you to manage your product inventory which is managed by Shopify. It's very easy to use and no need to manage another inventory other than the Shopify Store. It's a web-based application, so, no need to install anything to your desktop.
