Data science hiring process at Khatabook
With over 10 million monthly active merchant users, Khatabook has become one of the notable household names for kiranas and mom-and-pop stores across the country. Interestingly, many of the users using Khatabook apps are first-time internet users, meaning they have no previous digital footprint. Khatabook’s data science team uses the new insights they get from its users every day to understand user behaviour, mitigate payment and credit risk, forecast adoption and business growth, and lead generation and prioritisation. The company leverages data science to identify the nature of merchant users, whether they are suppliers or retailers, alongside the category of business they operate in, the primary purpose they are maintaining Khatabook for, etc. It also uses this to decipher strategy and evaluate product performance. When it comes to mitigating risk, Khatabook’s data science team uses advanced artificial intelligence (AI) and machine learning (ML) models to mitigate risk. Data science is also the core engine behind credit underwriting to merchants. Business predictability is another area where Khatabook’s data science team helps build the business decision. “We estimate the organic and paid customer growth six months in advance based on the data science framework, considering all other external factors, new user acquisition, old user retention aspects, marketing spends, and other important variables,” shared Ravish Naresh, CEO and co-founder at Khatabook. Currently, KhataBook has five different products – namely Gold Rate, Payments, Business Tips, GST, Salary – thus making a compelling use case of cross-selling and upselling. Cross-selling and upselling are usually performed in the mid-to-late stage of the conversion funnel, where a customer has already indicated they are likely to buy a product or service. Khatabook uses data science to identify potential users of other apps and identify who will be more likely to purchase the premium plans. “All the cross-selling and lead conversion efforts are prioritised using data science models,” added Naresh. Further, he said, at Khatabook, they handle risk by using a mix of auto-blockers that block suspicious users based on some preset rules and an ML model which gives a risk score for potential fraud users. “The auto-blockers and ML-based risk model work in tandem to prevent fraud within the Khatabook payment ecosystem. Our CTS (cheque truncation system) and FTS (fraud to sales) numbers have remained healthy and way below the industry cutoffs,” said Naresh.
