How to Pay
You pay in advance for the service. There are two options:
- Pay as you go - Pay by credit card (using Realex) or PayPal at the time of submission.
- Set up a prepaid account with us – this requires a pre-approved agreement with Euronext Dublin which takes approx. 2 weeks to set up. Please email our Finance Department firstname.lastname@example.org if you are interested in this option. If you have an existing pre-paid account you can extend this to include unlisted ISINs processing.
How do I set up an account with PayPal?
You need to set up a PayPal business account. PayPal facilitates multi-currency payment through bank transfer or direct from an established PayPal business account so this may be a suitable alternative for some users.
