A convenience-store eyewear program is working when it produces repeatable weekly contribution, keeps common powers and styles available, and requires very little labor. Total sales should be read with stockouts and display condition.
Track the core measures
- Units per week: The simplest velocity measure.
- Sell-through: Units sold divided by units available during the period.
- Gross-profit contribution: Net sales minus product cost.
- Power and style stockouts: Demand the display could not satisfy.
- Reorder frequency and speed: Whether gaps are restored before sales are lost.
- Inventory age: Slow product tying up limited space.
- Maintenance labor: Minutes required to reset and refill.
- Daypart demand: When the category is actually moving.
Review at 30, 60, and 90 days
At 30 days, confirm visibility, fast self-service selection, labels, and ownership. At 60 days, identify recurring power gaps and daypart patterns. At 90 days, review contribution, aging, reorder precision, and labor.
Diagnose the pattern
- Low interaction suggests placement or access.
- Interaction without sales suggests power, price, or style.
- Sales with empty positions suggests replenishment or shallow depth.
- A full rack with slow movement suggests poor allocation or duplication.
For convenience stores, prioritize units per week, stockouts, maintenance labor, and daypart demand. A universal sell-through target is less useful than a clear baseline and a rule for when to refill, rebalance, or reduce.
