One flat 5%, that's it
In Ireland, Eventbrite's published all-in fee is 5.9% + €0.79 per paid ticket. On a sold-out 500-person run at €30/ticket, that is about €1,280 in fees. Plentix charges a flat 5% with processing included: €750 on the same sell-out. US Eventbrite rates differ (service fee plus separate processing), but the pattern is the same: stacked costs vs one number.
