Hello,
It looks like you allow your vendor to create payment and shipping methods.
There is no built-in plugin to create such restriction and verification in HikaMarket since the workflow is too specific.
I would recommend to create a custom HikaShop plugin for the "onBeforeProductCreate" and perform the needed verification and refuse the creation for the vendor if he do not have shipping methods.
