Nearly a quarter of purchasers in a recent study said they typically complete work-related purchases online because that’s “where I consistently find the lowest prices.”

30% of business-to-business buyers say they make half or more of their work-related purchases online, but 56% say they expect to buy that much online three years from now, Forrester Research Inc. says in a study it conducted of more than 100 earlier this year with Internet Retailer.

Among the reasons B2B buyers like to buy online: The web is a consistent source of the “lowest prices,” a reason cited by 24% of study respondents; and the web is “the most credible source of product details,” as noted by 24%.

Forrester analyst Andy Hoar, who specializes in covering B2B e-commerce, presented these and other findings during a webinar last week sponsored by hybris software, an e-commerce technology provider. The webinar was hosted and moderated by Internet Retailer.

The web is also popular among B2B buyers for researching work-related purchases, the study found:
