We sell business to business. It's a requirement that we are able to handle pricing on "per product, per customer" basis. I like that we can do far more than just give a sight-wide discount to a customers. We are able to customize the pricing according to our customers buying habits.
We also offer small products that can ship via UPS/Fedex all the way through pallet sized products requiring custom freight options. The unlimited "shipping tables" allow us to create shipping options to cover the whole spectrum, but only show the relevant options in the cart.
Third, we have been a customer for 3-4 years and I can call the same person that help us navigate getting set up. I cannot emphasize the value in being able to speak to a human being when I am planning modifications or have questions that go beyond the basics.
These features are what secured our relationship with Nexternal. Review collected by and hosted on G2.com.
