Disallow financing combined with discounts?

Topic summary

A merchant wants to create a promotional structure where customers choose between:

  • 24 months at 0% interest through Affirm, OR
  • 5% discount (without financing)

The challenge is that standard Shopify doesn’t allow conditional hiding of Affirm based on applied discounts or specific products.

Proposed Solution:
Shopify Functions can conditionally hide payment methods at checkout based on cart criteria (such as presence of discounts). A developer mentions building an app that uses this functionality to hide Affirm when discounts are applied, offering to help implement this solution.

Status: Potential technical workaround identified, but requires custom development or third-party app implementation.

Hello,

I have Affirm on my site due to offering big ticket items. I want to create a “24 months 0% interest or 5% off” type of offering. It seems with standard Shopify you cannot make Affirm ineligible when offering discounts or disallow the use of Affirm with certain products. Has anyone found a work around with this? Maybe an app?

Thanks

Hi @MSchaffer30 ,

You can potentially hide Affirm as a payment method at checkout using Shopify Functions based on certain criteria. We’re building an app in this space and it should be able to solve for this particular use case.

Shopify has some documentation around this and we can conditionally hide Affirm as a payment method at checkout based on if a discount is present for an item in the user’s cart.

Feel free to reach out if you’d like us to help set this up for you :slightly_smiling_face:
