Prove repayment schedules still match before cutover

You’re the software engineer. Your team is in the room. Printed Oct 7, 2026.

A repayment migration becomes irreversible when the old calculation path is retired.

Complete coverage is essential, but every discrepancy must also be understood before members are affected.

Who you’d be doing this for

“I can handle a payment I expect. I can’t handle one that suddenly moves.”

Has an active installment loan with repayments planned around recurring bills.

What is at stake

A pre-cutover replay found schedule mismatches for 0.7% of active loans. You have to weigh the fixed release window against verified repayment accuracy for every affected account.

Why it isn’t already fixed

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

  • release timing vs account-level correctness
  • automated triage vs human verification
  • migration scope vs member remediation risk
  • shared dependencies vs clear ownership

Why Chime

Instant Loans depend on predictable repayment schedules for members using installment credit to manage short-term needs.
