how to add custom prices if customer orders certain amount of product?

Topic summary

A seller offers stickers in batches of 10 for £2.50 but provides volume discounts outside Shopify (£11 for 50 stickers, £18 for 100 stickers). They need a way to automatically apply these tiered prices when customers add multiple batches—specifically, reducing the total to £18 when 10 batches (100 stickers) are added to the cart.

Current Status:

  • The issue remains unresolved
  • One app developer has offered to create a custom POS extension to address this pricing challenge
  • A discovery call has been proposed to discuss requirements in detail

The core challenge is implementing quantity-based pricing tiers that trigger automatically based on total units ordered across multiple batch items.

I sell each product as a batch of 10 ( so 10 stickers for £2.50)

However, at the minute I am selling outside of shopify at custom prices e.g. £11 for 50 and £18 for 100

How do I make it so that if my customer adds 10 different batches of 10 stickers, the price is reduced to £18?

Thank you!!!

Thank you for sharing the idea.

I’m an app developer currently looking to develop a new product for the Shopify POS system, and perhaps I can develop a POS extension that can help solve your problem.
