TariffShark eTariff Packager Service

Since the first electronic tariffs were filed, the OPTM eTariff Packager Service team has successfully packaged more than 800 filings using TariffShark – the industry-leading eTariff management and filing software solution. And over that same period, the group has been fully supported by Links Technology Solutions Inc, the developers of TariffShark, and experts in IT and managed support, technology staffing, and web services since 1999.

OPTM eTariff Packager Service will transition to Links Technology Solutions Inc under its new name, TariffShark eTariff Packager Service. The Links Technology Solutions team is proud to continue providing this service as a complementary extension of the TariffShark family.

The staff of Arbo will provide consultation to Links Technology Solution Inc, during an interim period, to facilitate a smooth transition, and to assure the best possible customer service.
