Hello,
1/ I quote a previous message :
Otherwise, you OR your vendor would be paid and you need another transaction to pay your vendor (via the HikaMarket backend, with a good paypal integration) or ask your vendors to pay you (using an HikaShop order).
If your vendor do have entered his paypal email address, he will be paid directly. Otherwise your store will be paid directly.
2/ You can use any HikaShop payment plugin to be paid directly ; and then pay your vendor thanks to the HikaMarket backend interface ; including the HikaShop Paypal classic payment plugin.
3/ There is no default process since HikaMarket can be (and is) used for different workflows.
But the vendor payment happens when you click on the button to pay your vendors (in the HikaMarket backend).
You will then have the interface to pay your vendor(s) :
Like :

Or even :
