The factoring and discounting sector is emerging from a slowdown that has held it back for more than three years.The Institute of Factors and Discounters reported yesterday that debtor financing turnover of A$16.3 billion in the December quarter was the highest quarterly turnover the sector has recorded since early 2010.Factoring and discounting boomed in the years between 2000 and 2008, growing from a quarterly turnover of around $3 billion to reach $18 billion during that period.Business is starting to climb out of the post-GFC slump, but there is little likelihood of a return to boom conditions. More than half the sector's client base is in manufacturing and the wholesale trade - two industries that have been adversely affected by the high dollar.
