Would you charge B2B and B2C differently?

So we do window and wall coverings for residential and businesses. These are all end-use products and not for resell. I want to create separate check out portals with some specific features that are relevant to each group. For example I want to keep the check out process as simple as possible for residential, but give businesses a little more customization if I think its reasonable to expect them to know it, or possibly faster response times for contacts since its more likely time sensitive. So it would seem like I should charge businesses more since it might cost me more to provide these things, but businesses also place larger orders, whereas residential may place more service calls and need more hand-holding for installation.

Since most people here do signs presumably for B2B, is there anyone who has done both B2B and B2C? Would you charge them differently or the same?

 

The goal isn't to charge different prices for the exact same thing, rather that we don't have enough data to know which customer type is willing to pay more for what extra warranties or benefits (we just launched as a company). Hypothetically lets say our corporate prices are a bit higher because we will guarantee the delivery time. If a residential customer wants that, I don't really care if they want to make a business account. And if a business doesn't think that's important and wants to pay as little as possible, they can order through the residential portal and it makes no difference to me. But that one is more obvious since its basically the same as upgrading shipping. Less obvious would be like if we had to develop a system to make sure that the logo is the right size every time.

I just don't want to have a bunch of optional surcharges that might make people feel like they are being nickle and dimed. So I was wondering if anyone here has noticed any general patterns selling to each type of customer.
