More commercial b2b ecomm sites will sometimes not have product pages and instead just have one page that looks like a spreadsheet that you fill out and submit, the idea being the customer needs to order in bulk and is already aware of what the product is/doesn't need to be marketed to. You basically go down the lines on the spreadsheet and just put in quantities for each product.
That's the closest I can think of. There are ecomm sites that have been around since the 90s and haven't changed much but those either still have the product page/cart/checkout structure or are functionally just catalogues and require you to place an order by phone.
