Our AD2 partners — EbixCash, MakeMyTrip — send outward-remittance transactions in bursts. Travel season doesn't spread itself evenly, and Operations was keying tickets in one by one: queues, overtime, and re-keying errors at exactly the peaks when speed mattered most.

The key decision was sociological, not technical: ops lived in Excel, so the automation went to Excel. Any solution demanding a new tool would have died on arrival. We built a validated bulk-upload flow — row-level validation, so one bad row fails loudly and alone instead of blocking the whole batch.

The second decision: uploaded transactions flow through the existing Core Banking API integrations, not a parallel path. One ledger, one reconciliation story. A shadow pipeline would have doubled every future audit.

Around the upload, two adjacent time-sinks got automated: scheduled RBI compliance reports for the Business team, and risk-mitigation email alerts that flag suspicious transactions to Operations before they settle. Result: 80% TAT cut on the partner flow, on-time compliance at near-zero manual effort.

Lesson I'd generalize: find where the humans already are, automate the seam — not the human.
