Products: internal code and price for each customer

Hi,
I would need to assign, for a product, the internal codes and the sales price for each of the interested customers.

I tried to do some research but I can’t find whether this possibility exists or not.
Can anyone give me a suggestion?

Thanks

I think you can do individual prices, but I don’t use it

select rules for selling prices and you get the first drop down picture.

I only tried products, not services

Why would you want a different product reference pr. customer?

Maybe a product variant can be used?
