::Hi Noreen,
As Lewis mentioned, Lanham is fully integrated in BC. Lanham has been around for some twenty odd years and has a deep bench of features.
Lanham’s integration allows you to choose your own path of independence, whether you want to control all aspects of the EDI process, or engage Lanham or a partner to help with setup, mapping, etc. Other ISVs such as SPS Commerce or True Commerce seem to have more of a one size fits all model where the client would prefer a hands-off engagement with EDI. That’s my take, at least.
