Just flagging an issue I've been having with the Service Charges (btw this is nothing to do with Booking.com commission on SCs).
I set up a Service Charge at 6.1%. However the amount calculated on the Platform is different versus what could be reasonably expected.
As an example, on a $5,040 reservation, before service charge, the SC applied by the platform is $260.54 (booking.com shows 6.1% on the screen, next to it). The actual Grand Total confirmed to guests is $5,300.54.
Unfortunately the amount of $260.54 is only 5.17% of the Subtotal (i.e. markup), or 4.91% of the Total (i.e. margin). So nothing to do with the 6.1% I put in the system and displayed by booking.com on the reservation!
Normally the Total should have been 5,040 x 1.061 = $5,347.44 and in dollar terms, the Service Fee should have been $307.44.
In other words, booking.com under-charged by about $46.90 on this reservation.
Anybody else having this issue?
