Would you walk away from a million-dollar deal? When a negotiation has taken weeks of preparation, ending the discussion can feel like failure. Yet the value of an agreement depends on its terms, the resources it consumes and what your business must deliver afterwards.

Sun Tzu negotiation strategy begins with understanding your position before committing to a contest. Applied to business, this means preparing your alternatives, understanding the other party and recognising the point at which an agreement no longer serves your objectives.

A deal can be impressive and still be unsuitable.

On 14 October 2026, Reuters reported that Piper Sandler and Perella Weinberg Partners had ended merger discussions after failing to agree on financial and personnel terms.

For business leaders, the case raises a useful question: when should the desire to reach agreement give way to a reassessment of the terms? The lesson we can draw is that a proposed deal’s scale does not, by itself, establish its strategic value.

1. Understand your alternatives before you negotiate.

Your alternative is what you can realistically do if no agreement is reached. It might involve another supplier, a different customer segment, a phased project or postponing a commitment while you build capacity.

Make the alternative specific. What would it cost? How long would it take? Who would need to approve it? An untested possibility gives you less clarity than an option your team has checked.

This is where the best alternative to a negotiated agreement, often called BATNA, becomes useful. It gives you a basis for comparing the proposed deal with the practical consequences of declining it. A strong alternative still requires judgement about how and when to use it.

2. Understand the interests behind the other party’s position.

A request for a lower price may reflect budget pressure, uncertainty about the result or a need to demonstrate savings internally. Each explanation opens a different conversation.

Ask questions before making concessions. Which conditions matter most? Who makes the final decision? What risk are they trying to reduce? Understanding those interests may reveal a workable adjustment to scope, timing or payment terms.

The strength to walk away begins with the discipline to prepare.

3. Set your boundaries before pressure builds.

Decide which terms are acceptable and which would make delivery commercially or operationally unsustainable. Consider margin, payment timing, service capacity, responsibilities and the commitments your team would inherit.

Imagine a contract that looks attractive by revenue alone but requires payment far beyond your cash-flow capacity and a delivery schedule your team cannot support. Signing may create a larger problem than declining.

Agree the decision process internally. Your negotiator should know what they can approve, what requires further discussion and when to pause. Clear boundaries make a difficult conversation easier to manage.

4. Explore options, then decide whether to continue.

Walking away should follow a considered assessment. Before ending a negotiation, test whether a change in scope, sequence, timing or responsibilities could create an agreement both sides can deliver.

If the essential terms remain unsuitable, explain your position calmly. You can decline the current proposal while leaving room for a future discussion if circumstances change. Avoid using a threat to leave as a substitute for a credible alternative.

A practical negotiation preparation checklist.

Before your next important discussion, write down:

• Your objective: the outcome the business needs and why it matters.
• Your alternative: the realistic next step if no agreement is reached.
• Their interests: what you know, what you assume and what you need to ask.
• Your boundaries: the terms you can accept and the approvals required.
• Your options: the changes that might make an agreement workable.
