Most TSS pain isn't in TSS. It's in the gap between commercial systems and the customs workflow.
The data already exists
Goods descriptions live in the ERP. Movements sit in the TMS. Weights and locations live in the WMS. TSS wants a subset of all three.
Design the integration by direction
Push goods and party data from ERP into TSS. Push vehicle and container details from TMS. Push weights and packing details from WMS. Never let staff copy across.
The system view is set out in this TSS integration guide for GB-NI operations.
Handle the movement reference bottleneck
The reference is created after the customs entry lands. Model it as a callback, not a synchronous step.
Keep records where auditors look
UKIMS requires five years of retention accessible in the UK. Store the audit-ready record set in a UK-hosted system by default.
