IPC - Internet Pricing and Configuration / Internet Sales / Web channel CRM

Hi everybody,

We want to allow our customers and distributors to search for (their) products and then get a price displayed and allow them to save a quote.

How would you do this in SAP and why?

-With Internet Sales on top of ECC

-With webchannel in CRM

We have pricing already in ECC and want to keep it there. Do we need IPC for CRM or Internet Sales?

Any help is appreciated.

Gerald
