There are two options here, firstly our support team should be able to help you resolve issues, advise on best practices and organise free training for you.
However if you need additional assistance, you could consider outsourcing data loading or changes to GS1 directly. Our support team will be able to organise this for you. Please note, we charge a standard 'time & materials' fee of $120+GST per hour (plus disbursements where applicable) to conduct this work.
For more information on the above, please contact our support team on 0800 10 23 56 or firstname.lastname@example.org
