# Payments (landing & parking fees, fuel)

At participating airfields, services used (e.g. landing and parking fees, refueling, ancillary services) can be paid online. This is particularly practical for self-reported flights or when continuing a flight without a final landing – but it can also make a regular airfield visit more efficient.

**Payments can be processed as a** [**guest user**](https://help.airport.software/english/sign-up-guest-account/guest-account) - it is **not** required to create a user account in order to use this service. The [creation of a user account](https://help.airport.software/english/sign-up-guest-account/create-user-account) is recommeneded when using Online Services regularly.

An online payment for an aircraft is done in 2 simple steps:

1. Submit a payment request for an aircraft registration to a participating airfield.
2. Review the preview invoice and complete the payment.

After a successful payment, you will receive the invoice by email.

It is recommended to complete the payment process as soon as possible. If no payment is made, a payment request expires after 12 hours at the latest. A payment request also expires if payment is made by other means.

{% hint style="info" %}
Airfields may restrict the use of online payment, e.g. for aircraft whose owners pay by direct debit or that exceed a certain MTOM. Further information can be found on the info page of the respective airfield under [Participating airports and services](https://my.airport.software/POR/login/airports.aspx).
