Before signing off on AI for underwriting, collections, or credit decisioning, NBFC leaders raise practical concerns — about accuracy, borrower trust, integration effort, and what happens when the model gets it wrong. This FAQ addresses those concerns directly, for credit heads, operations leaders, and IT teams evaluating AI adoption without glossing over the real trade-offs.
1. What happens if an AI credit scoring model makes a wrong decision?
Every credit model, human or AI, makes some wrong decisions — the goal is to keep the error rate low and ensure there's a review mechanism when it happens. A well-implemented AI credit decisioning system flags low-confidence or borderline scores for manual review rather than auto-approving or auto-rejecting everything, which limits the damage from any single incorrect prediction. NBFCs should also build a borrower-facing appeal or review path, since a rejected applicant who believes the decision was wrong needs somewhere to raise it. Over time, tracking actual repayment outcomes against model predictions lets the NBFC identify where the model is systematically off and retrain accordingly, which is not fundamentally different from how a credit policy gets revised based on portfolio performance.
2. Will borrowers trust an AI voice agent calling them about their loan?
Borrower trust depends more on how the interaction is designed than on the fact that it's AI-driven. A voice AI system that clearly states its purpose, speaks in the borrower's preferred language, gives accurate information pulled from the loan account in real time, and offers an easy path to a human agent tends to be well received — borrowers generally care about getting their question answered correctly and quickly, not about who or what answers. Trust breaks down when the AI sounds robotic, cannot handle a slightly unusual question, or loops the borrower without resolution. NBFCs that pilot voice AI on lower-stakes interactions first — like EMI due date reminders or disbursement confirmations — before expanding to collections tend to build borrower confidence gradually rather than risking a bad first impression on a sensitive call.
3. How reliable is AI at analysing bank statements from small towns and non-standard formats?
Reliability varies with the quality and format consistency of the statements being processed, which is a genuine challenge in India given the number of different bank formats, regional cooperative banks, and scanned or photographed statements from applicants without digital banking access. A good bank statement analyser is trained across a wide range of bank formats and can handle scanned PDFs and even photographs of printed statements, but accuracy naturally dips with poor-quality scans or unusual formats it hasn't encountered before. NBFCs should ask vendors specifically how the system handles low-confidence extractions — the right behaviour is flagging the file for manual review rather than silently guessing at numbers. This matters especially for NBFCs focused on financial inclusion and semi-urban or rural lending, where standardised digital statements are less common.
4. Can alternate data scoring unfairly exclude certain borrower segments?
This is a legitimate concern, and it depends heavily on which alternate data sources are used and how the model is validated. Alternate data scoring is meant to expand credit access to thin-file and new-to-credit borrowers who lack a traditional bureau history, but if the underlying data sources (certain utility providers, specific telecom operators, particular UPI apps) are more common among certain demographics or geographies, the model can inadvertently favour or disadvantage specific groups. Responsible implementation involves testing the model's approval patterns across different borrower segments and data availability scenarios, not just testing statistical accuracy. NBFCs should also avoid using proxies that could indirectly encode protected characteristics, and should be able to explain, in a fairness review, why the model weighs each data source the way it does.
5. What is the biggest implementation challenge NBFCs face when adopting AI for underwriting?
The most common challenge is integration with existing loan management systems, core banking platforms, and bureau connections — AI models and decisioning platforms need clean, real-time access to this data to be useful, and many NBFCs run on a mix of legacy and modern systems that weren't built with easy API access in mind. Data quality is the second major hurdle: models trained or scored on incomplete or inconsistent historical data produce unreliable outputs regardless of how sophisticated the algorithm is. Change management within the credit team is often underestimated too — credit officers who have built careers on manual judgment need training and a genuine understanding of how the AI complements rather than threatens their role, or adoption stalls even after the technology is deployed.
6. How do NBFCs handle cases where the AI system is down or unavailable?
Any production AI deployment in lending needs a documented fallback process — typically reverting to manual review or a simplified rules-based decision path — so loan processing doesn't stop entirely if the AI system experiences downtime. NBFCs should treat this the same way they'd treat any critical vendor dependency: agree on uptime expectations with the vendor, have a clear internal process for staff to follow during an outage, and test that fallback process periodically rather than assuming it will work when actually needed. For voice AI handling borrower calls, this usually means calls automatically route to a human agent queue if the AI system is unreachable, rather than the borrower hitting a dead end.
7. Is it difficult to get regulatory approval or comfort for AI-driven lending decisions?
There is no separate "AI approval" process from the RBI — the regulatory expectation is that whatever decisioning method an NBFC uses, including AI, meets existing requirements around fair practices, explainability, and data protection. The practical difficulty NBFCs face is less about approval and more about being ready to demonstrate, if asked, how the model works, what data it uses, and why it made specific decisions. NBFCs that document their model governance, validation process, and audit trails from day one generally find this straightforward to demonstrate during inspections. Those that adopt AI tools without this documentation in place are the ones who run into friction, not because AI itself is prohibited or restricted.
8. What if credit officers resist using AI-generated CAMs or decisioning recommendations?
Resistance usually comes from a legitimate place — credit officers who have developed judgment over years of manual review are cautious about trusting outputs they didn't personally derive, and that skepticism is healthy in a lending context. The most effective rollout approach positions AI as a drafting and data-aggregation tool that saves the credit officer time on transcription and calculation, while leaving the actual credit judgment and sign-off with them. Involving experienced credit officers early in testing and refining the AI-generated CAM format, rather than presenting it as a finished mandate, builds buy-in faster than a top-down rollout. Over time, officers who see the AI consistently catch things they'd have missed manually tend to become the strongest advocates for wider adoption.
9. How do NBFCs prevent over-reliance on AI leading to weaker risk judgment over time?
This is a real long-term risk — if credit officers stop questioning AI outputs and simply rubber-stamp recommendations, the human oversight layer becomes hollow even though it exists on paper. NBFCs can guard against this by keeping credit officers actively involved in reviewing a sample of AI-approved cases (not just AI-flagged exceptions), maintaining regular training on how the models work and where they're known to struggle, and tracking whether override rates and manual corrections are trending down for the right reasons or simply because staff have stopped scrutinising outputs. Periodic model performance reviews, shared transparently with the credit team, keep the human-AI relationship active rather than passive. The goal is a credit team that understands and can challenge the AI, not one that has outsourced its judgment entirely.
10. What are the risks of choosing the wrong AI vendor for lending operations?
The main risks are poor model performance that isn't caught until bad loans start showing up in the portfolio, weak data security practices that expose sensitive borrower information, and vendor lock-in where switching later becomes operationally painful because the NBFC's workflows are too tightly coupled to one platform's specific structure. NBFCs should evaluate vendors on their willingness to be transparent about model logic and limitations, their track record with other RBI-regulated entities, their data security posture, and how easily their output integrates with existing loan origination and core systems. A pilot phase with a defined evaluation period and clear success metrics — turnaround time, accuracy against manual review, fraud catch rate — is a more reliable way to de-risk vendor selection than relying on a vendor's own claims alone.
