The functional core is consistent across industries: assign each product an HTS code and export classification, screen customers and suppliers against denied-party lists, determine whether a shipment needs an export license under regimes like the US EAR or ITAR, test goods against trade agreement rules of origin, file import and export declarations (directly or through a customs broker), and calculate duties and fees as part of total landed cost. GTM software earns its license fee mostly by keeping regulatory content current: tariff schedules, sanctions lists, and license rules change constantly, and stale data is how violations happen.

Positionally, GTM fills the gap between the ERP and logistics execution. The ERP knows the part, the supplier, and the price; the TMS knows the carrier and the milestone; neither knows whether the consignee is sanctioned or whether the goods qualify for preferential duty. Good practice gives one owner, usually a trade compliance lead, authority over classification and screening decisions. Bad practice scatters that knowledge across brokers and forwarders, and the gaps surface during an audit or a seized shipment.
