New Year 2021 Support

We are focused on ensuring our 24/7 software support is always available to keep your Sequoia installation functioning correctly and free of technical issues over the Christmas period and the end of the Brexit transition.

The ASM Helpdesk team will be on call throughout the holiday period.

They are trained and equipped to support any and all technical issues relating to the Sequoia software, rather than Customs procedures, declarations content and compliance issues.

As we can only assist with matters related to the technical support of the Sequoia software, we have listed below parties who may be able to help with other issues.
