Hi,
This option will be available in a future HikaMarket release (payment per vendor).
We introduced the "vendor limitation" in HikaMarket 1.3.0 so you can forbidden several vendors in a same order. At this moment, you will pay just one single "person" (one vendor).
We are working on the edition of the payment plugin in the front-end. So the vendors will be able to create/edit their payment methods and fill their information.
We will also introduce a simplified paypal management which will use the paypal email in the vendor configuration. So the vendor won't have to configure they paypal plugin method, it will be done automatically.
