Sales grew 8.6% in May, according to Dydacomp's SMB index.
Just as April showers bring May flowers, a 4.3% downturn in April web sales preceded an 8.6% rise in May for small and mid-size retailers indexed by Dydacomp, a provider of order management software.
"The May 2012 Dydacomp SMB Index showed its single largest year-over-year monthly growth rate in the past year, for both gross sales and number of orders," says Fred Lizza, CEO of Dydacomp.
The Dydacomp SMB Index, prepared for Internet Retailer, is based on data compiled from more than 1.7 million orders per month at more than 1,500 e-commerce operators across more than 15 product categories—accounting for more than $200 million in combined monthly retail sales; the retailers are users of Dydacomp's order management software.
Dydacomp notes that performance numbers in its SMB Index tend to be lower than broader e-commerce market figures because the index does not include growth at the largest online retailers. In addition, information in the index includes a small percentage of sales processed in stores and contact centers using Dydacomp's order management software, and in many cases such sales are declining, the company says.
