Trace every dollar from receiving to the customer’s door. Fixed occupancy and software fees meet variable pick‑pack minutes, materials, and carrier or courier charges. Include shrink, cycle counting time, and QA rework. Compare parcel, gig courier, and bike options by distance, density, and service window complexity to prevent hidden erosion of margin.

Volume unlocks efficiency, but only at the right radius and schedule. Model orders per hour, batches per picker, and stops per courier under peak and lull conditions. Find the break‑even daily order count where contribution turns positive, and pressure‑test sensitivity to weather, promos, and demand shifts.

Protect margins with thoughtful levers customers accept. Offer delivery tiers, minimums, and free pickup that steer baskets upward without undermining trust. Bundle slow movers with fast favorites, use cut‑off times transparently, and calibrate localized pricing to reflect density, not desperation, sustaining healthy unit economics as you scale.
