Integrate Quickbooks with Woocommerce -- 2

have a project I hope you can help me with. I am looking for someone able to integrate Quickbooks desktop to ecommerce (woocommerce or other), so that the clients fully inventory and data on Quickbooks gets fully synced to the ecommerce, including tier pricing. I actually have 3 separate clients asking me for the same thing, except one is B2C, the other two are B2B.
Please let me know if this is an area of expertise for you.
