Abstract: There is provided a system and method of automated processing of online social networking data for integration with an inventory management system. A merchant or other selling entity may post data to a social networking platform, where the posted data includes an item for sale. A transaction processor may process the post data to determine the item for sale with a backend merchant inventory management system or other sales platform. The transaction processor may then poll comments to the posted data to determine whether any users are requesting to purchase the item. If the transaction processor identifies a purchase request, the transaction processor may interface with the merchant's sales platform to determine availability, cost, and other parameters, and may generate an invoice for the item. The invoice may be communicated to the user, and the transaction processor may update the merchant with results from processing the invoice.
