While key benchmarks such as average order value, conversion rate, and shopping cart abandonment rate have been compiled, analyzed, and published widely for business-to-consumer (B2C) eCommerce, the business-to-business (B2B) equivalents for these measures have been hard to find due to the relative immaturity of the space. However, several quality sources of B2B benchmarking data have recently started to emerge. This report, a resource for the B2B eCommerce playbook, identifies what sources of B2B benchmarking data exist today and how those sources can be useful to B2B companies exploring where, how, and when to invest more substantially in their eCommerce operations.
