- Promotion reporting review and commercial evaluation
A clearer way to judge promotional performance.
The review established a structured comparison of promotion scale and discount efficiency. Gross sales, discount cost, net sales, orders, units and order value were brought into one evaluation approach, giving promotion reviews a clear commercial logic beyond headline revenue.
The challenge
A promotion can generate substantial sales while leaving less value in the business than a smaller, more efficient offer.
The review needed to make that difference visible. The question was not simply which code produced the highest sales; it was how much discount was required, what customers bought, and what revenue remained afterward.
My contribution
My work focused on connecting the available promotion reporting with a consistent commercial evaluation.
The review brought together promotion-code breakdowns, weekly effectiveness views, deal-group reporting, and the report's metric definitions. It separated promotional scale from discount efficiency and made the relationship between gross and retained order value explicit.
The evaluation structure
| Measure | Commercial question |
|---|---|
| Gross sales | How much sales activity did the promotion record? |
| Discount and discount percentage | How much incentive was used to support those sales? |
| Net sales | What revenue remained after promotional discounts? |
| Orders and units | Did the offer create more transactions, larger baskets, or higher unit movement? |
| Gross and net average order value | How much basket value remained after the discount? |
| Discount per order and per unit | How intensive was the incentive at the transaction and product level? |
This structure made promotional performance easier to interpret across offers with different discount depths and basket sizes.
Reading the commercial trade-off
For the same gross sales, a lower discount preserves more revenue. The comparison still needs the offer's objective: inventory clearance, launch support, and recurring acquisition can justify different incentive levels.
The review therefore pairs discount efficiency with orders, units, availability, and sell-through. It also keeps the reporting period and calculation definitions attached to each comparison.
Promotion net sales are revenue after discounts. The company financial close has a broader cost and deduction structure, so the two views serve different decisions.
The delivered result
The completed review produced a repeatable structure for evaluating promotion output and cost together.
The commercial questions became explicit: which offers retained more value, which depended on deeper discounts, and which supported the intended stock or launch objective.
This gave the reporting work a practical operating purpose: compare offers on their economics and customer response rather than choose the next promotion by gross sales alone.
