The one thing I always look for before starting a new website is inventory sync. How can I sync my vendors inventory? How many times will it sync per day to make sure everything is still available for buying?

I could not find this in your knowledgebase, but if you get it I will mostlikely be making a switch.

The hardest thing I run into on shopify ecommerce site is the fact that if you have multiple vendors the company I was using to sync my inventory costs even more. Its hard during those months that I make nothing. Sometimes I cant pay for the sync. Then a customer might buy something that My vendor no longer has.
