YITH WooCommerce Multi Vendor allows you to turn your store into a multistore where vendors manage their own product and earn a commission on every sale.
The combined use of these two plugins allows generating commissions for the vendors also when the purchases are made through the one-click checkout.
After installing, activating and configured both plugins, the one-click checkout button will show like in the image below.
After clicking on the button, users will be redirected to the payment page.
For further details about YITH Multi Vendor settings, please refer to the official documentation.
