In Guesty, markups are used to increase or decrease a listing's accommodation fare by a certain percentage. You can use this to cover booking channel fees. When you add a markup it is calculated and presented to potential guests on the relevant booking channel.
For confirmed reservations from Expedia, the accommodation fare in Guesty does not reflect markups. To resolve this issue and make sure that the guest paid the correct and full amount, we recommend checking the reservation in question in Expedia Partner Central and confirming that it includes Expedia's commission.
