During peak season, a retailer can post record traffic, orders and revenue while earning less from each sale. The dashboard looks successful long before the full economics become clear.
In our experience, Black Friday and Cyber Monday now operate as an extended promotional period. Retailers spend more days discounting, competing for attention and fulfilling elevated order volumes. That makes the cost of growth harder to judge from headline sales figures alone.
Traffic, conversion, orders and revenue dominate real-time dashboards because they are visible and actionable. Teams naturally use those numbers to judge whether a campaign is working. Because sales update faster than some costs, the decision to increase a budget can arrive before the evidence needed to support it.
When Growth Gives the Wrong Signal
During the seven-day promotional period from November 25 through December 1, 2025, USAWheels recorded a 410% increase in website users and a 225% increase in orders compared with the equivalent period in 2024. Our more established Canadian operation, CanadaWheels, saw users rise 72% and orders grow 35% over the same comparison period.
Those results demonstrated strong demand generation. They did not, on their own, establish whether the additional sales justified the discounts and spending required to secure them. As a CEO, I need both answers before deciding to scale.
The Costs Behind the Growth
Manufacturer-funded promotions can create room for compelling offers, with customer savings reaching up to 40% on selected purchases. These offers can include buy three, get one free on eligible wheel or tire sets, alongside retailer-funded storewide discounts of 10% to 15%, depending on the promotion.
The manufacturer’s support helps fund the offer, but the retailer still needs to account for its own discount. Funding eligibility and reimbursement terms also matter when estimating what remains from each transaction.
At the same time, paid advertising investment rises as retailers compete for shoppers. Shipping and fulfillment expenses add another cost, particularly in categories such as wheels and tires. Incremental campaign expenses belong in the promotion’s economics.
After accounting for these factors, our contribution margin was approximately 15% below ordinary operating levels. Roughly two-thirds of the impact came from discounting, with the remaining third attributable to higher advertising and shipping costs. We still considered the period a worthwhile investment in customer acquisition. The lesson was to judge that investment with a clear understanding of its full cost.
Put Contribution Margin on the Dashboard
Contribution margin shows what remains from sales after variable costs. For a promotion, that means accounting for product costs, customer discounts, applicable manufacturer funding, advertising and variable fulfillment expenses, including incremental shipping costs.
It belongs alongside revenue and order volume while decisions are still being made. Strong return on advertising spend can coexist with a promotion that leaves too little contribution after other costs.
Retailers should separately assess whether they are acquiring customers and generating sales, and what those sales contribute after the costs required to generate and fulfill them.
Set the Rules Before Peak Season
My recommendation is to establish minimum contribution-margin thresholds before promotions begin. Teams need a clear basis for adjusting an offer or slowing spending when growth becomes too expensive.
Track contribution margin alongside traffic, conversion, orders and revenue throughout the event. Review advertising efficiency and incremental shipping expenses daily, using estimates where invoices lag and reconciling them as actual costs arrive.
I would also track both total contribution dollars and contribution as a percentage of net sales. A lower margin percentage and a higher total contribution can coexist; leadership needs to see the tradeoff explicitly. Evaluate offers by supplier, brand and product category. A storewide discount can produce very different outcomes across products with different margins and funding arrangements.
Finally, separate the lead-up to Black Friday, the weekend and Cyber Monday into distinct decision periods. Adjust budgets and offers as profitability changes.
The dashboard should show how much growth remains economically sustainable after every incremental cost is accounted for. That is the information leadership needs to decide what deserves more investment.
