Pallet

Pallet has made it incredibly simple to add wholesale pricing to my Shopify store. Very simple onboarding process, easy to setup the customer intake form, I suggest you add it to the contact page.
Create custom pricing rules, customer groups and add it to the store in less than 30 minutes.
Easy to design to be on brand with custom colors and types.
Highly recommend adding pallet app to your store if you want to get into wholesale pricing and make larger quantity sales.
