Hi @jeycherries
Because in Shopify admin, there is no feature to discount products by %, if you’re running a B2B store we suggest you use the B2B/Wholesale Solution app.
- Here you can use the Custom Pricing(CP) module
- Images when using the module in the app:
- Create a rule in the module to apply prices to specific products:
- With settings:
-
Customer: All customers, Logged in, Not logged in, Specific customers, Customer tags
-
Product: All Products, Specific Products, Product Collections, Product Tags
-
Price: Apply a price to selected products, Decrease a fixed amount of the original prices of selected products, Decrease the original prices of selected products by a percentage (%)
- Results displayed outside the storefront: All products are 20% off the original price
I hope that you find it useful for your business.
