A congress takes eleven months. Here is where the platform stands in each of them.
Nothing below asks you to move a file between two systems. That is the entire product.
Name the congress, set the dates and the sessions, connect the account your institution already uses to receive money. Or clone last year and change three fields.
One link, distributed through your own channels. Registrants pick their rate, pay, and submit their work in the same sitting. Your jury and invited speakers register at no charge, and cost you nothing.
Papers are handed out at random inside each session, skipping anyone with a declared conflict. Reviewers score against your rubric and never learn whose work they read.
Scores consolidated, author names visible again to you and only you. Accept, reject, rank, and send every decision from here with a record of what was sent to whom.
Mark who attended, issue certificates to attendees, reviewers and committee. Compile the proceedings and deposit them where they will be kept permanently, with their DOI.
