Cash flow from operations can take a hit when businesses expand, said Pavan Kumar Vijay, founder of Corporate Professionals, which also brings SMEs to the stock market through its merchant banking division. Typically, working capital costs can go up, reducing operating cash flow. The absolute amount of business that SMEs are doing has continued to grow faster than their larger cousins. Sales are up 115 per cent since FY18 compared to a 93 per cent increase for BSE 200 companies. Both have grown faster than the economy overall, as represented by gross domestic product (GDP), which grew 73 per cent during the same period.
