Pilots prove agents can triage hardship requests or nudge early payers; scaling to 100k+ accounts demands architecture, ops and change mastery. Australian lenders succeeding here treat agents as infrastructure, not experiments.​

Scaling Challenges and Fixes

Common pitfalls and counters:

  • Data silos: Fix with federated access (no central lake needed); agents query live CRMs/cores via secure APIs.​

  • Volume spikes: Design stateless, event-driven agents that auto-scale on cloud infra; handle rate-rise arrears surges seamlessly.​

  • Consistency creep: Lock policies into versioned rulesets; auto-flag drifts for review.​

  • Team adoption: Start with agent-assist (whispers, summaries), evolve to full autonomy where safe; measure NPS alongside efficiency.​

Tech Stack for Scale

  • Orchestration layer: Multi-agent frameworks routing tasks (e.g., hardship → assessment → comms).​

  • Data backbone: Real-time streams from payments/telecomms; RAG over policy/docs for context.​

  • Observability: Metrics on latency, accuracy, escalations; alerts for anomalies.​

  • Resilience: Multi-model, failover logic; local data for sovereignty.​

Timeline

Pilot

1 workflow (e.g., arrears triage) on 5% volume

80% auto-handle, <5% errors

3 months​

Expand

Add 2-3 cases (hardship, collections) to 20%

Cost save 30%, outcome parity

6 months

Scale

Full servicing suite, 80%+ volume

Arrears drop 15%, compliance score 95%+

Returns at Scale

Mature deployments yield:

  • 40-60% servicing cost drop.​

  • 20% arrears reduction via early action.​

  • Compliance uplift: faster ASIC responses, lower provisions.​

Scale smart: measure outcomes, iterate ruthlessly, keep humans central. Your portfolio – and P&L – will thank you.​
