POS Point of Sale addition to the software

We would love to have Point of Sale options on this software (and we would gladly pay for it).  

Currently we have to use Shopify to sell pre-made items out of our showroom and we have our showroom listed online for purchasing and shipping. 

If we could just somehow set up products to Skip production and pick up/shipping that would be great! Just a similar user interface as Shopify!
