of each paid registration, card processing already inside it

The middle two lines move. The last one does not. We take less when the card costs more, which is the whole mechanism.

Registrations that carry no fee
Your jury, your invited speakers, your own committee. Charging you for the people donating their labour to your congress would be indefensible.
€15.00
Below this, the guarantee lifts
On very small amounts the fixed part of a card fee can exceed eight percent by itself. Those registrations show the true cost instead of a promise we cannot keep.
Refunds
Our fee comes back, minus what was already spent
Card networks do not return processing on a refund. We return our management fee net of that irrecoverable cost, and this is written in your terms before you take a single payment.

Why a flat number and not the cheapest one

You budget in June for money that arrives in November, from cards issued in thirty countries. A rate that varies by card origin is not a rate, it is a range — and a range is what turns a congress budget into a guess.

Eight percent sits below what a general ticketing platform actually costs at academic registration prices, once its own processing is added. But the argument is the certainty, not the margin.

What we are not

Not the seller of your registrations
Your institution stays the merchant of record and keeps its exemptions. The money lands in your account, and you move it when you want.
Not your archive
Papers and reviews are deleted six months after the congress, with warning and a full download. Permanence belongs to a repository built for it, and we deposit there on your behalf.
