First-launch conversion is usually lower than steady-state — err on the safer side of your CVR estimate.

Split the order into a smaller first shipment + air freight top-up if capital is tight.

Method

Launch units = Sessions × Conversion rate × Units per order × Coverage weeks. Reorder-by = Launch date + (Coverage weeks × 7) − Lead time.

Frequently asked questions

Is it better to over- or under-stock a launch?

For unproven products, under-stock slightly and airship a top-up. For proven brands with strong pre-orders, stock deeper.

How do I estimate launch traffic?

Use email list × open rate × click rate, plus paid-media session forecasts. Discount influencer estimates aggressively.
