When using online registration you may need to produce invoices for participants with their payment information for accounting purposes. An invoice is a unique and singular document containing a fixed set of data which should not change.

Invoices are not be linked to just a single participant record, they may group multiple participants together under a single invoice. Each invoice contains the data as to which specific entry fees have been linked to that invoice, this allows multiple invoices to be generated for participants for later payments or refunds if required. Invoices have their own set of fields to be used which relate to the invoice settings.

Invoices can also be generated as e-invoices in the ZUGFeRD format. It is important to note that an invoice does not necessarily have to be linked to a payment process and can therefore also be created and sent independently of online payment. One invoice could also contain several payments of different participants.

Creating and sending invoices can optionally be combined with the email confirmation, but is generally independent of the registration process. Application examples for creating and sending invoices can be found in our How To.
