Kraljic portfolio matrix
You are about to treat a strategic item as a leverage item, which is the classic misclassification.
Full analysis
Plotting profit impact against supply risk puts warehouse automation firmly in the strategic quadrant: high impact, few capable suppliers, high switching cost. The playbook for that quadrant is partnership, joint performance targets and long-horizon contracting. A public tender belongs to the leverage quadrant, where suppliers are interchangeable. Run the classification with your own numbers before any negotiation is scheduled; if the item scores leverage after all, tender without hesitation.

Transaction cost economics and asset specificity
The real question is not who supplies, but what governance survives the dependency you have already created.
Full analysis
Site-specific automation is the textbook case of asset specificity: once installed, both sides are locked in, and the contract, not the market, does the governing. A tender pretends the market can still discipline the incumbent; it cannot, and the incumbent knows it. Spend the effort on the extension's governance instead: open-book costing, benchmarking rights, step-in clauses and a defined exit path. Those clauses are what make the relationship contestable again.

Tactical empathy and calibrated questions
You are preparing a threat you cannot execute, and the other side will hear that in the first meeting.
Full analysis
A tender you do not mean is a bluff, and bluffs leak. Instead, make the constraint the incumbent's problem: "How am I supposed to defend a five-year extension to my board without a market reference?" forces them to argue your case. Label their position, ask calibrated how-questions, and let the qualified challenger, once real, do the talking without ever being mentioned. The goal is a better extension, discovered by them.
