Business in the debtor finance market picked up in the September quarter, with discounting and factoring turnover up 7.2 per cent on the previous quarter.This was a strong result after the industry reported negligible growth for the year to June. The industry has struggled to regain the momentum it had before the financial crisis.The Debtor & Invoice Finance Association (formerly the Institute of Factors and Discounters) reports that debtor finance turnover in the September quarter was A$16.5 billion - up from $15.4 billion in the June quarter.Discounting, where the seller of the trade debts retains the accounting and debt collection functions, accounted for $15 billion of the turnover. Factoring, where the finance company takes over the accounting and debt collection, accounted for $1.5 billion of turnover.The number of clients increased from 4471 in the June quarter to 4544 in the September quarter.DIFA chairman Lee Clarke said in a statement: "We generally witness a spike in the September quarter, as businesses prepare for the slowdown in the payment cycle at the turn of the calendar year."
