Continental Wine & Spirits review for Sumtracker Inventory Manager

I was astonished to find that although there are many inventory management systems, very few both calculate average costs and provide the ability to receive purchase orders. Sumtracker is the most cost-effective option I have been able to find in Shopify's network, and their customer service is highly responsive, communicates clearly, and is helpful. I would happily recommend them, especially if you are a new business.
