The Megaventory extension for Magento syncs products from Magento to Megaventory. This means that, if you want to use the same SKU in more than 1 different Magento installations that are both integrated with the same Megaventory account, you will have to add the product in each Magento separately. After you do, the stock will be synchronized.
​
It is also possible to use different descriptions or pricing in your different Magento installations The limitation is that the price and description that you will see for this product in Megaventory will be the ones of the Magento installation where you last updated this product. The prices in the Sales Orders created through Magento will remain correct.
