The report Online Retailing in Australia 2011: Technology Investment was compiled by analyst firm, Forrester, also indicated investment priorities for retailers in areas such as replacing core eCommerce platforms, mobile commerce, back office integration and technology to support multi-channel retail.

About half of respondents surveyed indicated plans to replace their core eCommerce platforms in next 24 months, and that retailers were steering clear of SaaS, trying to manage most of their software development and site administration in-house.

"As a result, the growing use of open source eCommerce platforms will plateau in Australia, product content management will become an important area of focus in its own right, and skills shortages will place pressure on current staffing models," the report said.

Respondents were also expecting their business to grow 29 per cent on average in the year ahead. Forrester forecast the online retail sales will grow into a $33.3 billion market by 2015. About 28 per cent of respondents said they would significantly expand their technology investment in the next few months, while 75 per cent were planning some sort of growth.

As these businesses continue to grow, so will their appetite for enhanced website features, business management tools and closely integrated systems, which could put a strain on core eCommerce platforms.
