QuickBooks POS and WooCommerce Integration

Our friends at [login to view URL] wrote an extension to integrate QuickBooks POS and WooCommerce, unfortunately they are not answering my request to add a feature that should have been there in the first place given the importance of it. And I offered to pay for the feature to be added. Problem 1: Products created on WooCommerce side can be synchronized and created on the QuickBooks POS side if not existent. I need the Sync to occur the opposite way, I need the extension to be modified to create and synchronize products from QuickBooks POS into WooCommerce. Problem 2: We have 2 stores and 1 "HQ" server, part of the same extension, the QuickBooks "webconnector", is installed on HQ, that's where on-line order will be processed and fulfilled, but HQ does not have any inventory in stock since it is just a server that keeps sales records from the other 2 stores, so if we sync the inventory levels from HQ "on hand" levels, WooCommerce inventory levels would always be "out of stock", we need the webconnector to be modified to add the inventory levels of HQ, Store 1 and Store 2 and then sync the inventory levels with the WooCommerce app. The WebConnector does already have inventory qty synchronization available as long as "Item number" on QB POS matches the Product "SKU" number on WooCommerce. To the right developer this should be a walk in the park since majority of the modification is done in the file that passes the instructions to the webconnector. Wish List but not mandatory: Synchronize also the UPC codes, may require to modify the mysql db on the WooCommerce Side, the WooCommerce side should be modified to also show the UPC code in the Product description, .
