Signing Is the Easy Part.
Moving Is Not.
Inventory has to move, systems have to talk, and someone has to teach the 3PL how your business actually runs.

3PL Onboarding and Transition
The contract gets signed and the real work starts. Inventory has to physically move without losing accuracy. Systems have to be built, mapped, and tested against real order profiles. And the provider has to be taught how your business actually runs — not the version in the RFP, the version with the exceptions, the seasonal quirks, and the accounts that get handled differently because they always have.
Most of what goes wrong is predictable. Inventory does not reconcile at cutover, and nobody can say whether it was lost, miscounted, or never left. The integration passed every test and then failed at live volume, because test files are clean and real order files are not. The provider's labor plan was built on your projections rather than your actual pattern, so the first week is understaffed at exactly the wrong hour. And when an exception hits on day one, nobody has decided who owns it.
The transition is where those get prevented rather than discovered. Sequencing the inventory move so accuracy survives it. Standing up the systems and testing them against real files, not sample data. Training the provider's team on the processes and exceptions that make your operation yours. Being in the building when the first real volume lands, because that is when the gap between the plan and the floor shows up.
Then there is the part most transitions skip. What happens if the provider drops the ball. Not as a contract clause, but as an operating plan: what gets pulled back, what runs manually, who makes the call, and how fast. A transition without a fallback is a bet that nothing will go wrong during the single riskiest period of the relationship.
GoVia works this end to end — planning the transition as a project, then standing in the building while it executes. The partners doing it have signed 3PL contracts, moved inventory into a new provider's building, and lived with the result the following Monday. That is a different qualification than having modeled it.
