How to set up multiple payments (tutorial)

Dear support

I'm using the Hikashop business version and the multivendor market version.
Sorry, but I can't find a tutorial to find out how to set up a multiple payment method.
I want to implement the feature that the customer has to pay directly the specific vendor and should receive the specific invoice from the same vendor.

Thank you very much for your awesome support
best regards, Fritz

Hello Fritz,
Can you give me more information about what do you exactly mean by "to set up a multiple payment method" ?
Thanks .

Hi, thank you for asking.
I would like to implement following process:

If a customer buys a product from vendor B, he should receive an invoice from vendor B.
If a customer buys a product from vendor C, he should receive an invoice from vendor C.

I hope, that it is possible

Thank you very much for your patience and your support
best regards, Fritz
