Organizer billing

In Organizer → Billing you configure everything necessary to issue invoices.

Organizer information

The tax data that will appear on invoices: company name, NIF/CIF, and full tax address (with its two address lines).

Billing series

Invoices are numbered within series. Create series to organize your billing by year or type:

1. Click Create New Billing Series
2. Indicate the series name (e.g., "2025 Series"), the starting number, and an optional description
3. Click Create Series
4. Select the active series that new invoices will use

You need at least one billing series to be able to issue invoices (also for co-organizers).

Tax configuration

Define the applicable taxes for your billing (VAT applied to registrations).

Invoice format

Customize the appearance of the invoices:

• Invoice logo (JPG or PNG, maximum 2 MB)
• Footer text: appears at the bottom of all invoices (registration data, terms and conditions, etc.)

Relationship with events

Each event also has its own billing configuration in Configuration → Billing of the event, where the series and taxes for that event are chosen. See Billing configuration.
