Please select the membership category as reflected by your invoice. Ensure you insert your invoice number in the appropriate field. If the membership category doesn’t accurately reflect the number of employees in your organisation, please contact us and we will amend your invoice.

If your membership invoice has been modified, for example, to reflect a discount as a result of joining the membership of NISO last year, please contact us at 01 465 9760 and we can take the payment of your renewal subscription over the phone.

Should you require your purchase order to be associated with your payment, please insert below the invoice number at checkout.
