Hi all, i need little help about experts,

I added extra payout types to VendorPayoutTypes type name is shipment

Why i need this ?: if order shipping cost is 0 i will charge shipping price to vendors, shipping cost coming from shipping company api.

i added a row to ?:vendor_payouts table type with shipment or other no matter.

it appear on admin/vendor account but doesnt effect to balance, i just want (-) calculate that type records,

what can i do ? or which hook best for this problem ?
