Most business owners who discount have never checked whether it's working.

They do it because they've always done it. Because it feels like the right move when you want to win the work. Because the fear of losing a job outweighs the discomfort of holding the price.

What almost none of them have done is go back through the data and ask whether the discount made any difference.

I want to share a conversation that changed how I think about this — and I'd already thought about it quite a lot.

The director with an 81% win rate

A commercial HVAC contractor. The director responsible for quoting had been doing it for over a decade. He was good at it. He knew the industry, understood what clients wanted, and had built a strong reputation over twelve years.

His win rate: 81%.

Four in every five jobs he pitched for, he won.

He was also discounting almost every single quote — around 10% on average. He'd built the habit over years because he believed, sincerely, that it was how he kept winning work. Take the margin hit, secure the contract. That was his model.

When we went back through every quote from the previous twelve months and looked at the outcomes, what we found surprised him.

There was no correlation between the discounts and the wins.

Jobs won at full price. Jobs won with 15% off. Jobs lost with discounts applied. Jobs lost without them. No discernible pattern suggesting the discounts were the reason clients chose them.

He was winning because of the quality and reputation of the business — not because of the number at the bottom of the quote.

The discount was just money leaving the business before it even arrived.

What "testing the habit" actually looks like

We didn't suggest removing discounts entirely. That felt too rigid, and there are situations where flexibility on price makes commercial sense — a strategic new relationship, a contract that opens a new sector, a client worth winning at a short-term cost.

What we suggested was a controlled test: cap discounts at 5% for a period and observe what happens. If jobs start being lost that would have been won at 10%, you have real data. You can adjust. The decision is always reversible.

But the existing data gave no reason to expect that outcome.

On the previous year's project revenue of £532,000, with an average discount running at just under 10%, reducing that to 5% was worth £26,600 in additional profit. Not from a new client. Not from extra hours. From questioning an assumption that had been running, unexamined, for years.

The hidden mathematics of a discount

There's a calculation most business owners know in theory but underestimate in practice.

If your net margin is 9% — which it was for this business — a 10% discount on a contract doesn't just reduce the revenue. It eliminates the profit entirely, and more. You end up delivering the job at a net loss, before you've even paid for the overhead associated with it.

A 5% discount at a 9% net margin leaves you with 4p in the pound. You've cut your return in half on every job where you apply it.

This is why pricing decisions at the point of quoting matter so much. By the time the year-end accounts arrive, the damage is already done. An accountant can see the margin is thin. But the decisions that created that margin were made months earlier, at the moment of quoting, based on a habit nobody had questioned.

The maintenance contract problem

The same business had fourteen active maintenance contracts with a combined annual value of £880,000.

Most hadn't had a price review since well before 2024. One client had been on the same contract price since 2019. Seven years, no increase.

This wasn't a deliberate strategy. Nobody had built a process to review contract pricing annually. So prices drifted. Costs went up. Inflation ran at uncomfortable levels for several years. And the contracts continued at whatever figure had been agreed years before.

A 3% increase across those contracts, phased over six months and explained simply to clients, was worth £26,400 per year.

Not an aggressive hike. Not a test of the relationship. Just catching up, incrementally, with the cost of doing business.

And crucially: none of the clients had been asked. The assumption that they'd push back, that the relationships were too fragile to survive a modest price increase, had never been tested either.

What the data usually shows

I've been through this process with a number of businesses now. The discounting pattern appears regularly. So does the unmaintained pricing schedule, the contract that hasn't been touched in years, the quote that goes out at cost-plus-a-little because that's how it's always been done.

In most cases, when we actually look at the data, the fear is worse than the reality. Clients are less price-sensitive than owners assume. Win rates don't collapse when discounts are reduced. Most contracts survive a 3% inflationary increase without drama.

The problem isn't the pricing. It's the absence of anyone asking the question.

The question worth asking this week

When did you last look at whether your pricing is still right?

Not the headline rates — the actual outcomes. The win rate data. The margin by job type. The contracts that haven't moved in years.

If you'd like to find out where the pricing gaps are in your business, the Profit Gap Tool at tool.mbsaccountants.co.uk takes about four minutes. It covers costs, margins, pricing, retention and average order value and gives you a personalised view of where profit may be leaking.

If what you find warrants a conversation, you can book a free Profit Discovery Call with Jason, my head of growth, and we'll go from there.

Pricing decisions are made in your business every day. The question is whether they're based on evidence — or on a habit that's never been tested.
