It is calculated when the organizer accepts the participation, based on the weight they record at that point — not the weight estimated at request time —, then charged to their card when the participant confirms. Example: a participant hands over 5 kg at $8.00 per kilogram, that is $40.00, which they pay directly to the organizer; if the organizer has an individual account, GP360 charges 10%, or $4.00, to their card. The participant pays $40.00 and nothing more. A minimum applies when the percentage yields less — CAD 1.00, €1.00, US$1.00 or XOF 650 depending on the currency: on a $3.00 shipment the commission is $1.00, not $0.30. It never exceeds the shipment amount. No registration or monthly subscription fees.
