Sale taxes on dropshipping with various various suppliers

Sale taxes on dropshipping with various suppliers

1st month in business
Let’s say, I’m located in New York and my apple supplier is in California. Ted, a client, in Texas orders apples, I don’t charge him sale taxes since I don’t have a nexus in Texas.

3rd month in business
I get another supplier that sells only oranges and it is located in Texas.

Question:

If Ted orders more apples, do I need to start charging him sale taxes even though he is not buying the product that the supplier in Texas is producing (oranges)?

If that’s not the case, how can I set in Shopify sale taxes by product/supplier location?
