A stable approval rate is masking a material shift in who drives the underwriting decision.
Holiday checkout volume protects conversion while the changed signal weight raises questions about consistent treatment of credit-thin shoppers.
Who you’d be doing this for
“I tried the same plan on two purchases, and one went through while the other didn’t.”
Miguel Reyes · Retail shopper
A credit-thin shopper using Pay in 4 for a holiday purchase at checkout.
What is at stake
A purchase-history signal is gaining weight for credit-thin shoppers while the overall approval rate remains steady. You have to weigh a fast, observed mix change against evidence of inconsistent underwriting decisions.
Why it isn’t already fixed
Every obvious fix costs something else. That’s the part you’d have to decide.
- stable approval rates vs changing decision drivers
- holiday conversion vs consistent treatment
- automated alerts vs verified evidence
- signal preservation vs model-use risk
Why Affirm
Pay in 4 depends on real-time underwriting decisions that remain defensible as shopper populations change.
