Buyer side, the group price is the final price — period. Merchant side, three plans, Early Bird launch pricing, and a commission that drops to 1.8% on the White-label plan.
No fees on your side to use the marketplace. It's guaranteed by the system, not by a policy we could change tomorrow.
No service fee, no buyer commission. The ticket shown on the group buy is exactly what you pay.
Card, SEPA or MoneyGram: no Terra fee is added at checkout. The merchant covers all of it.
The group price is sealed the moment the group opens. No one — not even Terra — can change it after.
Just one case where a small fee applies: converting your money in or out (for example into another currency). It's roughly 1.5%, charged by the conversion partner — never by Terra. As long as your money stays on Terra, it's €0.
