Hi Zach!
We totally understand how important it is for sellers to be able to utilize shipping labels for Wholesale orders, and we're working on this potential. However, I want to mention that directing buyers who contact you through Etsy (either the Wholesale or retail platform) to purchase from your personal site would be considered fee avoidance, which is against our terms of use. You can read more about that here:
https://www.etsy.com/legal/wholesale-sellers/?ref=listEngaging in fee avoidance could result in suspension of account privileges or account termination. We ask that if a buyer has found your products using our website, you keep the sale on Etsy.
If you have any questions about this, please let me know. Thanks for being a part of the Wholesale marketplace!
