When customer pays with Credit Cards, order receipts sent to vendor show correctly both Payment Gateway fee (3.5%) and Commission to vendor (89.1% before tax/shipping).
Example: Customer places an order of EUR 105 value. Based on commission and fee settings, the net proceeds transferred to vendors should be EUR 91.33 = 105 – 3.5% Gateway Charge (EUR 3.68) – Admin-fee (EUR 10)
However, the actual amount transferred to vendor is €95.00 instead of €91.33. This means, the payment gateway (3.5%) = €3.68 is not deducted from Vendor’s commission before paid out. Charge & Transfer records on Stripe confirms this.
