25% improvement in loan collections by using Robylon’s AI voice agents
A fintech lender serving over 25 million MSMEs moved 90% of its collection calls to Robylon’s AI voice agents. It now makes 3 times more calls per day, and net collections rose 25%, offsetting the extra calling cost more than 4 times.

Who is the client?
Our client is a fintech company, with over 25 million MSMEs as their customers across several products. One of their major product offerings includes providing short-term credit to MSMEs. The re-payment for such credit is to be made on a daily basis (EDI, Equated Daily Installments).
For missed EDI payments, the client makes reminder calls to the customers. As their customer base was growing rapidly, the scalability of making reminder calls was becoming infeasible due to cost considerations.
What was the challenge?
Collections calls are necessary but repetitive. In most cases, they just involve reminders and follow ups to the customers to make them pay back on time. However, our client faced several challenges:
No centralized system to access critical data real-time
- Calling data scattered across multiple agents (eg number of calls made, % calls connected)
- Inconsistent and delayed data entry by agents leading to reporting challenges
- No single dashboard to provide live status of collections (eg number of active agents, % total defaulting customers called, % collections made)
Scalability challenges
- Increasing costs due to the need to increase the number of calling agents
- Redialing logic was not followed in over 30% of cases (eg if a customer promised to pay by 3pm, and if they had not paid by then, they had to be called again)
Because of these challenges, efficiently solving for collections was a major priority for our client.
How did Robylon solve it?
Robylon’s AI voice agents are designed to effectively perform high-value, repetitive calls at a fraction of the costs of human agents. Hence, our client was keen on exploring how Robylon could solve their problems.
We did a pilot for around 3 weeks where our AI voice agents dialled up some low risk customers reminding them about their missed payments. Our pilot was a success and we were able to increase collections by 10% already within 3 weeks.
Hence, we are now onboarded to handle 90% of all collection calls using our AI agents. Only escalated and priority cases were to be handled by human agents. Here is a brief of how we approached the problem:
Step 1: Specialized AI agents to refine the calling SOP
- A concise 2 page SOP was provided to set the context for the AI agent
- Transcript of 1000+ minutes of high quality call recordings fed into the model to train and identify patterns
- SOP was refined using the historical transcripts to handle edge cases
Step 2: Building, testing and deploying voice AI agents
We developed specialized voice agents for collections with the following features:
Voice setup
- Mix of English, Hindi and regional languages (Tamil, Kannada, etc.)
- 10+ variations in voices across male and female options
- Slight variations in tonality based on the number of missed payments (eg milder tone for up to 2 missed payments)
Human-like conversational measures
- Ability to not just speak and listen, but also to engage in 2-way conversations
- Natural speed and pauses while speaking along with acknowledgment of customer responses
Defining the guardrails
- Strict compliance with applicable rules around collections calls
- Always remain polite, concise and to the point
We tested and iterated upon the voice agents with 250+ scenarios covering most of the edge cases we could think of (e.g. how to handle rude customers, what to respond in case a customer is busy, etc.)
Step 3: Setting up the calling operations
The next step was to set the calling process to make these calls using our AI agent:
- Every day, defaulting customers’ data was given to our specialized risk-analysis AI agent. It created a priority order list of customers to call based on risk analysis parameters.
- The voice agent made calls to the customers based on the defined priority. Post the call, the captured data was updated in the system real-time (eg by when the customer promised to pay)
- Certain calls were flagged for human intervention (eg in cases of rude behaviour)
- Redialing criteria was defined and automated (eg redialing in an hour if a call remains unanswered, redialing to remind customers to pay if they hadn’t paid by the promised time)
Step 4: Structured reporting and post-call analysis
Since data capturing was made real-time and streamlined by automation, it was possible to do real-time analysis of calls and track critical parameters. A single view dashboard was created covering the number of calls made, % calls answered, % amount collected, etc.
What were the results?
Robylon’s voice AI agents solved the problems of scalability while additionally saving on costs too. Using our voice agents, the client was able to make 3 times more calls per day with only a fraction of additional cost they otherwise would have had to spend.
What is more, the net collections increased by 25% which offset the extra calling costs by more than 4 times.
