How to create multi-product checkout?

Is there any option to create checkout with fixed price but for multiple products or services, for example, I want to make a page to sell consultant hours, at $100 the hour, It’s not a donation because the price is fixed, but also fixed doesn’t work because a customer can buy multiple hours, not only one at a time.

@dcolon - thank you for chiming in and asking! We will get the Commerce team on this and get back to you shortly.
