Last week I was reviewing financials with an agency owner who couldn’t figure out why his margins were shrinking. Revenue was up 15% year-over-year. New clients were signing. The sales team was hitting targets. But operating profit had barely moved.
We dug into the details. His team had started offering “competitive discounts” to close deals faster. Nothing dramatic. Just 8-10% off here and there to get contracts signed.
The math told a different story.
When you’re running at 20% operating margin and you start discounting 10%, you don’t lose 10% of your profit. You lose half of it. Your operating margin drops from 20% to 10%.
Most agency owners don’t see this coming because they think about discounts in terms of revenue impact. But discounts don’t touch your cost of sales. They go straight to margin.
Here’s how it works in practice.
You’re billing $100K monthly with $60K in direct costs and $20K in overhead. That leaves you with $20K in operating profit – a healthy 20% margin.
Now your sales team starts closing deals with 10% discounts. Revenue drops to $90K. Your costs stay exactly the same – $60K direct, $20K overhead. Your operating profit becomes $10K.
Same business; Same delivery; Same team; Half the profit.
“Should I do something where if it’s over a certain amount they need to run it by me?” This agency owner was asking the right question, but he was already behind the curve.
The real issue isn’t approval thresholds. It’s that most sales teams have no idea what they’re actually giving away when they offer a discount. They see it as a small concession to close the deal. They don’t see it as cutting the owner’s profit in half.
This is why sharing revenue numbers with your team without cost context creates teams that push for growth but ignore margins. They’re optimizing for a number that doesn’t tell the whole story.
The fix isn’t complicated, but it requires changing how your team thinks about pricing.
First, your sales team needs to understand your actual margins, not just revenue targets. When they see that a 10% discount costs you 50% of your profit on that deal, the conversation changes.
Second, if you’re going to allow discounting, build it into your pricing from the start. Price high enough that a 10% discount still leaves you with acceptable margins. Don’t start at break-even and hope nobody asks for a better deal.
Third, track discount patterns by salesperson and by deal size. Most agency owners discover that their biggest discounts go to deals they would have won anyway. The client was already sold – the discount just moved money from your pocket to theirs.
The agency owner I mentioned implemented a simple rule: any discount over 5% requires a margin calculation before approval. Not a revenue impact – a margin impact.
His team started closing deals at full price again. Not because they weren’t allowed to discount, but because they finally understood what discounting actually cost.
