Hi potteryhouse,
There is this free Phreebooks Open Source ERP (https://github.com/phreebooks/PhreeBooksERP and http://www.phreebooks.com/pb-forum/) which has a POS and ZenCart module that allow stocks from the Phreebooks inventory to be uploaded to Zencart and also download sales order from Zencart. I think this Phreebooks Plus Zencart is one of the best free solution for small business who has an outlet using POS and an online store and want to keep a single inventory for both. Everything is perfect for Phreebooks now except for products with attributes.
Currently, Phreebooks have it own product attributes but it has a problem when uploaded to Zencart. For example, if I have a product with 6 colors and 5 sizes, when uploaded to Zencart, Zencart will list it as 30 different product instead of 1 product with different attributes like Stock by Attribute. It a pity that the current version of Phreebooks can't work with Stock by Attribute.
In your next version, would you be able to add some connectors to link up your Stock by Attribute and Phreebooks product attributes? It will be perfect if this can be done and I am sure it will benefit a lot of both ZenCart and Phreebooks user.
