A sales rep closes a deal. The customer pushed hard on price. The rep offered 35% off to get it over the line. Everyone celebrates.

Nobody thinks about what just happened to the next five years of revenue from that account.

That 35% discount isn’t a one-time concession. It’s the new baseline. When the renewal comes up, the customer’s contracted price is 35% below list. The renewal quote inherits it. The customer expects it. Every future transaction with that account is anchored to the decision one rep made under pressure on one Friday afternoon.

The math most companies don’t do

A product lists at €100,000 per year. The rep discounts 35% to close. The customer pays €65,000 in year one. If the customer renews for five years at that price, total revenue is €325,000. At list price, it would have been €500,000. The discount cost isn’t €35,000. It’s €175,000 over the life of the relationship.

Now factor in a standard annual uplift. Most B2B contracts include a 3 to 5% price increase at renewal. But 3% of €65,000 is €1,950. At list price, 3% would be €3,000. Even the uplift compounds against the discounted base.

Why this happens

Sales reps are compensated on closed revenue, not on margin or renewal rate. The cost of an excessive discount is externalized — the rep gets the commission, finance absorbs the margin impact, and customer success inherits an account with difficult economics from day one.

The rep has no system flagging that this discount will cost €175,000 over five years. The information that would inform a better decision isn’t visible at the point where the decision gets made.

The connection to retention economics

Whether the customer pays list price or 35% below it, the cost to serve them is the same. The implementation effort, the support load, the account management time — all identical. But the revenue is 35% lower. Heavily discounted accounts become the most expensive to serve relative to their revenue. They consume the same resources as full-price accounts but contribute less.

What to do about it

Make the lifetime impact visible at the point of decision. When a rep submits a quote with a 35% discount, the system should show what that means over the expected customer lifetime. “This discount reduces projected five-year revenue by €175,000” changes the conversation. The information was always true. It just wasn’t visible.

Set floor prices based on margin, not just discount percentage. If the floor ensures that even a maximum discount still yields viable renewal economics, the worst case is manageable.

Tie some portion of sales compensation to retention or margin. If reps only get paid on closed revenue, they’ll always optimize for the close. If even a small portion of compensation is tied to whether the customer renews at or above the original deal value, the incentive shifts. That’s a bigger organizational change than the first two, but it addresses the root cause.

Pull a report on all deals closed in the last two years. Look at the discount given at acquisition. Then look at the renewal price on those same accounts. Calculate the gap between what you would have earned at list and what you actually earned.

That number is the cost of your current discounting approach — accumulating quietly, deal by deal, invisible in any single transaction but significant in aggregate. Once you see it, the conversation about discount governance and floor prices stops being theoretical.

Every discount is a commitment. Not just to this deal. To every deal that follows it with the same customer.
