Registration that is confirmed only when the payment is

Delegates register on the event website in a short, focused flow: they confirm their email with a one-time code, choose a registration type and a ticket, add optional items, answer your questions, upload any documents you require, review the price and pay. You decide who can register, for what, at what price and until when.

Example with sample data: the price summary a delegate sees before paying.

Registration and payments

What you can do

  • Registration types and tickets

    Kinds of attendee, such as international delegate, exhibitor, speaker or media, each with its own capacity, dates, visibility and the tickets it may buy. Every registrant picks exactly one ticket; add-ons such as a gala dinner or a site visit are optional.

  • Questions and documents

    Questions per registration type, shown only when another answer calls for them, with consent tick-boxes and file uploads. Each uploaded document shows as checking, accepted or rejected with a reason.

  • Prices, discounts and taxes

    Early-bird prices and dates, discount codes and single-use vouchers, tax rules per ticket and country, service fees and scheduled price changes.

  • Approvals and waitlists

    Registrations that need approval wait for your team, and the card is charged when they are approved. When a ticket is full, delegates join a waitlist and receive a time-limited offer when a place opens.

  • Groups and changes

    One person can register several colleagues, each with their own answers, with one payment and one invoice. From Manage my booking, delegates change add-ons, pass their booking to a colleague or cancel, within your policies.

  • Card or bank transfer

    Payment on a secure hosted card checkout, or by bank transfer where you offer it, with instructions and a reference.

Rules it keeps

  • The server calculates every price. Delegates see the quote it produced and pay the balance still owed.
  • A booking is confirmed only once the payment is confirmed. In between, the delegate sees that their payment is being confirmed.
  • Registering, paying and refunding are safe to repeat: each happens once, even on a slow connection.
