Im looking for an app that can handle discounts from a base price. E.g. When a customer customize a product, the product will have a price.
Then I would like a table, like the one below, where the customer can see the given discount. E.g. they buy 5 units, they save 10%, if they buy 10 they save 12% etc.
Are any of you familiar with such an app?
It sounds like you're looking for a quantity breaks discount app. These apps offer tiered based discounts based on the volume of product that the customer buys. In this case, Quantity Breaks + Bulk Discount is a great option to look into. With this app you can offer volume discounts on quantity. It will allow you to set up tiered pricing to reward bulk purchases using a fixed amount or percentage price breaks. Feel free to check out their app demo to see it in action.
If there is anything else I can help you with, please let me know.
App Selly can help you to offer quantity discount:
We can hide the discount table and display your discount scheme image instead.
By default, the table is generated dynamically like this demo:
