Clear the duplicates in merchant reports instead of filtering by hand

You’re the data engineer. Your team is in the room. Printed Oct 8, 2026.

Merchant reports show more Pay in 4 plans than the underlying checkout records.

Accurate plan volume protects merchant trust, while historical reporting definitions must remain stable.

Who you’d be doing this for

“My finance lead asked why our report has plans we can’t find in yesterday’s checkout records.”

Joost Hamilton · Payments Operations Manager

Reconciles checkout activity and plan volume for a merchant using external reporting.

What is at stake

A source event is causing 2.8% of Pay in 4 plan rows to appear twice in merchant reports. You have to restore accurate counts without changing valid historical reporting.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • fast report recovery vs durable model correction
  • source fidelity vs duplicate suppression
  • merchant confidence vs stable definitions

Why Affirm

Interest-free payment plans depend on merchant reporting that matches the plans shoppers actually selected at checkout.
