BTR (Born to Run)

Amazon & D2C glossary · Harpy Media

BTR (Born to Run) is Amazon’s vendor program for launching new products with a substantial upfront purchase order: the vendor nominates a launch quantity and guarantees the sell-through; Amazon buys the inventory for an initial window (commonly ~10 weeks) instead of ordering its usual cautious trickle.

What is BTR?

It’s the institutional version of B2R’s logic: the vendor funds the bet, Amazon provides the deep shelf. For products with real launch support behind them, BTR converts the honeymoon window into a full-force debut. For products launched on hope, it converts inventory into a return shipment.

The mechanics and who it fits

Invitation/qualification-based (vendor-side). The vendor proposes the launch quantity with a sell-through commitment; Amazon issues the opening PO sized accordingly. If velocity meets projections, the algorithm’s own reordering takes over seamlessly — the launch graduates into standing replenishment. If it doesn’t, the guarantee settles the gap (returns or compensation per terms). The fit profile: vendors with launch marketing budgets, comparable-ASIN track record, and products whose demand can actually be generated on schedule. The misfit: untested products where the vendor wants Amazon to underwrite curiosity.

Using the window properly

The opening weeks decide everything. Sequence the full launch kit BEFORE the PO lands: deal placements scheduled, sponsored campaigns built, content complete, and a velocity target per week that keeps pace with the guarantee. Watch sell-through against the curve weekly — a launch running 20% behind at week three needs intervention (promo depth, ad budget) while there’s still runway, not at week nine when the guarantee looms. And treat the post-window handoff deliberately: the goal is graduating into algorithmic replenishment, which means the velocity you built must be honest demand, not just discounted motion.

In practice

A vendor launches a seasonal product through BTR: 12,000-unit opening PO, deal slot in week two, full ad campaign live day one, weekly sell-through reviews against a 70%-by-week-nine curve. Velocity tracks hot; the guarantee clears with three weeks spare; Amazon’s reorder logic picks the ASIN up mid-window. The vendor enters the season with national depth and graduating demand — the program working exactly as designed, because the launch plan existed before the inventory did.

⚠️ Watch out. A vendor accepts a BTR PO sized to ambition rather than to marketing capacity — no launch spend, no deal slots, “the product is strong.” Week ten arrives with 45% sell-through; the guarantee triggers; the balance ships back at their cost with return-handling fees attached. The deep shelf they wanted becomes a deep lesson in the difference between placement and demand.

💡 Harpy tip. Size the BTR quantity to the marketing plan’s proven conversion ability — then add 10% for courage, not 200%. The guarantee clause reads exactly the same either way; your margin doesn’t.

How Harpy Media helps

Launch inventory should always match launch capacity — vendor BTR or seller-side stock depth, we size both to the demand engine behind them. Inventory is a bet; we build the odds.

BTR FAQ

What is Born to Run on Amazon?

A vendor program where Amazon issues a large opening PO for a new launch — sized and guaranteed by the vendor’s sell-through commitment (commonly ~10 weeks).

What happens if BTR inventory doesn’t sell?

The vendor makes Amazon whole per the guarantee — returns or compensation. The vendor carries the launch risk.

When does BTR make sense?

When real launch marketing backs the product: deals, ads, and a track record that makes the velocity commitment a plan rather than a prayer.
