How a Mumbai BFSI cooperative bank shipped an RBI-compliant loan lifecycle on WhatsApp
A Mumbai-headquartered multi-state cooperative bank with 47 branches and a ₹2,180 Cr advances book was losing high-intent loan applicants between branch visit and disbursal. We built an RBI Master Direction-aligned loan lifecycle on WhatsApp — KYC consent capture, EMI nudges, NPA-stage dunning and grievance routing — all on utility templates with a full DPDP audit trail. Loan-disbursal conversion lifted 21%, recovery contact rate jumped 2.4x and the operations team retired three legacy outbound dialers.
What was bleeding revenue
- 1
Loan application drop-off between branch visit and disbursal sat at 38% — applicants ghosted on document collection because follow-up was manual phone calls and physical visits.
- 2
Recovery contact rate for 30–90 DPD buckets had fallen below 41%; missed-call campaigns were no longer compliant under RBI fair-practices and TRAI scrub volumes had killed SMS reach.
- 3
No single audit trail tying each customer touchpoint to a documented consent record — a real exposure during the RBI Master Direction inspection cycle and DPDP Act 2023 readiness.
- 4
Operations were running three legacy auto-dialer vendors at ₹38 lakh / quarter combined, with collections agents tied up dialing instead of handling escalations.
What we shipped
Built a 23-step loan lifecycle flow — eligibility → KYC consent capture (DPDP-compliant, time-stamped) → document upload via Meta Native Flow → underwriter handoff → disbursal confirmation → first-EMI welcome.
Deployed a tiered dunning ladder on utility templates: T-3 / T-1 / T+0 EMI nudges, then 7-day / 15-day / 30-day past-due ladders with RBI-compliant language reviewed by legal.
Wired the grievance flow per RBI Internal Ombudsman timelines — auto-acknowledgement inside 1 hour, SLA escalation at 7 / 14 / 21 days, with branch manager Slack ping on breach risk.
Persisted every inbound + outbound message + consent event to an append-only audit log indexed by customer ID; one-click export for RBI inspections.
Retired two of three outbound dialers; redeployed 11 collections agents from dialing to high-value 90+ DPD case work via a unified RichAutomate inbox.
From kickoff to production in three phases
Compliance review + WABA setup
- •Legal sign-off on every template per RBI fair-practices

- •WABA + Green Tick application kicked off
Flow build + core banking integration
- •Loan-lifecycle flow with 23 nodes + branch routing
- •Core banking webhook for EMI state + LOS handoff

Phased rollout across branches
- •Pilot on 6 branches, then state-wise ramp
- •Dunning ladder A/B tested against legacy dialer cohort
- •Three legacy dialers decommissioned by Week 18

“For us as a regulated entity the audit trail was non-negotiable. RichAutomate gave us a single append-only consent + message log we can export to the RBI inspector in minutes. The 21% lift on loan conversion is what the CFO talks about — the audit trail is what lets me sleep.”
