Orders from wholesale users appear in the 'Orders' page of WooCommerce alongside your orders from regular customers. You can either manage all the orders together, or filter by retail or wholesale to view them separately.
It's also easy to create manual wholesale orders on behalf of your users, for example of you accept phone orders. When you create a manual order in WooCommerce and select a user with a wholesale role, the correct price for their role will be used automatically.
