Measured result
10pp
promo margin lift, from 17% to 27% across 4 fulfilment centres
3x
promo revenue tripled (+275%)
Weekly promo nominations were running on gut feel.
Existing forecasts overestimated promo demand by 9–14x on average.
Buyers relied on gut feel and used discount depth to clear stock.
Promo share of net revenue remained at 7.6%, while indiscriminate discounting diluted margin and inventory drifted away from actual sell-through across four DACH fulfilment centres.
After Duvo
- Daily agent-driven nomination cycle
- Promo margin lifted by 10pp (from 17.0% to 27.0%)
- Promo share of net revenue rose to 24.0%
- Total margin held at ~32% with slightly lower discount depth
We were running promo nominations based on gut feel and deeply flawed forecasts, using discounts primarily to clear stock. Duvo changed the game by running the full cycle daily. By balancing margin, depth, and actual inventory across all fulfilment centres, we lifted our promo margin by 10 points and tripled revenue without cutting deeper.
