I am considering DNN as the solution for our ecommerce but I have a couple issues I can't quite figure out.

I need to be able to retrieve pricing externally. We have customer level pricing on every sku and storing it on the website is just not an option.

The other thing is I need to be able to retrieve tax externally too. We have certain items that are taxable for some customers and not taxable for others.

Does anybody any DNN ecomm modules that supports this?

Thanks in advance for any assistance of direction.
