Zoho Commerce B2B

Zoho Commerce B2B

Hello, I have signed up for a Zoho Commerce B2B product demo but it's not clear to me how the B2B experience would look for my customers, in a couple of ways.

1) Some of my customers are on terms and some pay upfront with credit card. How do I hide/show these options during checkout?
2) What does the actual experience look like for an existing customer as it relates to order history + customer portal? I think that in ideal world, they're one in the same, and perhaps they are with the commerce solution.

I see great value in using Zoho for my B2B business since I'm a very happy Zoho Inventory user but I'm having a very hard time envisioning it for B2B since there are no tailored online demos, webinars, etc.
