Key Sales Volatility captures sharp or repeated movement in sales that may affect repayment reliability. MSME businesses often face seasonal demand, customer concentration, commodity cycles, project-based billing, or market disruptions, so volatility must be interpreted with context. For example, a supplier dependent on one large buyer may show high sales in a few months and very low sales in others. This matters because uneven sales can create cash-flow gaps, stock build-up, delayed collections, and higher working-capital dependence. The underwriter should compare sales volatility with GST returns, bank credits, order book, receivable ageing, and industry seasonality. The common mistake is to either reject volatility automatically or ignore it completely; the key is to understand whether it is explainable and manageable.
