Order Fulfillment for Retail Partners Please Help

Hi, sorry i have so many questions:

  1. When fulfilling orders for retail partners at a discounted price, should I use the “Order” or “Transfer” function in Shopify?

  2. I have different prices for my wholesale partners compared to retail customers. Will using ‘Orders’ accurately reflect these separate sales prices? and how?

  3. Does the “Transfer” function affect inventory and sales tracking?
