Every salesperson knows the sunk cost fallacy, even if they have never heard the name. The more months you put into a deal, the harder it becomes to leave it. Eight months in, you are no longer evaluating the customer. You are protecting your own effort.
This is the story of the deal where I learned the opposite. Eight months of work. A five-hour meeting. One million rupees on the line. And we still walked away.
Eight months, two corners of the city
I had been on this project from the very beginning. It was not a quick pitch and a purchase order. It was eight months of collaboration across teams, of calls and revisions and follow-ups, and of physically moving between two places that sat at opposite corners of the city: the project site and the project office.
If you have ever done that commute, you know what it does to you. Hours in traffic, dust on your shoes from the site in the morning, a clean shirt and a laptop bag for the office by afternoon. You carry the same deal in your head through both worlds. By the end of those months, I knew the drawings, the people, the delays and even which gate the security guard preferred I use.
Then the day for the decision finally came.
The five-hour meeting
I walked in alongside an ASM, an Area Sales Manager from our side. The meeting started in the morning and did not stop for five straight hours. It was one of the most intense rooms I have ever sat in.
We did everything right. We explained our value proposition clearly. We had supported the customer through every stage. We had followed all the engineering standards and codes, with nothing cut and nothing hidden. We brought the full picture: trainings, documents, and site-level testimonials from other projects where the solution had performed.
And still the conversation kept returning to the same place. The customer kept hedging our solution against the competition, line by line, rupee by rupee. There was no interest in the total, end-to-end value addition. The question was never "what will this do for our project over its life?" It was always "who is cheaper?"
The clock moved. The tea went cold. For me, those were five anxious hours. I could feel eight months of work sitting on the table, and a million rupees with it. Every minute I was calculating what I could concede to keep the deal alive.
Towards the end, my ASM did something I did not expect. We thanked the customer for their time. And we walked away.
The line that stayed with me
I was stunned. I was replaying the last eight months in my head on the way out of the building, trying to make sense of what had just happened. Then the ASM said one thing that I have carried with me ever since:
"Yes, we are here to close the sale. But more importantly, we are here to close it the right way. We need to know when to walk away."
That line rewired how I think about sales. And honestly, about business in general.
Why walking away is the hardest skill in sales
Most sales training teaches you how to start conversations, handle objections and close. Almost none of it teaches you to leave. There are good reasons it is hard.
- Targets are loud. A quota is a number on a screen every single day. The cost of a bad customer is quiet and arrives later.
- Effort feels like equity. Months of work make you feel you have earned the deal. You have not. Effort is not a payment, and the customer owes you nothing for it.
- Discounting feels like a rescue. One more concession, and maybe it closes. But a discount does not fix a value problem. It confirms to the customer that price was the only thing that mattered.
- Walking away looks like failure. In the moment, it takes more confidence to stand up and leave than to stay and bend.
The uncomfortable truth is that a customer who only sees price will keep seeing only price. If they push you to the lowest number now, they will push you again on delivery, on payment terms, on support and on the next order. You are not winning a customer. You are signing up for a negotiation that never ends.
When to walk away: a checklist
Not every difficult customer is a bad one, and walking away should never be a reflex. But these are the signals I now watch for, and the more of them you tick, the clearer the decision becomes.
- The customer only talks price, and ignores total cost, lifecycle value and risk.
- They keep changing requirements after you have already responded to the last version.
- They will not let you meet the real decision maker. If you are stuck talking to people who cannot say yes, see my note on how to reach the decision maker in B2B sales.
- They use your proposal mainly as leverage against a competitor.
- They dismiss your testimonials, documents and standards compliance as noise.
- Meeting after meeting ends without a clear next step or a clear timeline.
- Winning would mean breaking your own standards, your margins or your team's morale.
One more filter I use: ask yourself how much of your pipeline this single deal is eating. If it is consuming time you could spend on better customers, it is already costing you far more than it will ever pay. That is the same logic behind the 80/20 rule in sales: your best hours belong with the deals that actually move the number.
What happens after you walk away
I wish I could tell you the story ended with a dramatic phone call the next morning. Real life is more varied than that. In my experience, walking away leads to one of a few outcomes.
- Sometimes they come back. Once the customer has lived with a cheaper option and its gaps, they remember the team that stood on value. When they return, the conversation is different, because they now understand what you were protecting.
- Sometimes they never do, and that is fine. You may have saved yourself months of pain: late payments, endless rework, and a relationship that drains your team. You will never see the invoice for the trouble you avoided, but it was real.
- Your time comes back. The hours you would have spent chasing a price-only customer go to people who value what you do.
- Your positioning gets stronger. Customers, competitors and your own team notice who holds the line. A company that can walk away is a company whose price means something.
If you are in sales
Not every deal deserves your yes. When a customer only sees price and not value, staying longer will not change that. Be generous with your effort, but never confuse effort with a reason to close. Do the work to understand the customer, make your case clearly, and then be willing to let the answer be no.
If you are leading a team
Your people are watching how you handle these moments. They notice whether you chase every number or protect the standards. One walk-away with the right explanation teaches more than a month of training. Do it in front of them, explain the reasoning on the way out, and you give them something no playbook can: permission to be professional over desperate.
I lost that deal. I am still glad of how we lost it.
