I am currently running Quickbooks POS through my brick & mortar store and am looking to link this system with Shopify so we can automatically get inventory updates and also push those updates to shopify.
I have no idea what something like this would entail so please ask if you have any questions or feel free to make any recommendations.
ps. The price quoted is just a jump off price, I could be way off base so please quote what you think is fair. References would be great too if you've done this for another company.
