LSPL (Large Scale Product Launch)
LSPL (Large Scale Product Launch) is a 1P vendor programme for introducing genuinely new products to Amazon: the vendor supplies large quantities upfront with strong advertising investment, and Amazon commits to buying stock at scale, distributing it across fulfilment centres, and supporting the launch with visibility.
What is LSPL?
LSPL (Large Scale Product Launch) is a 1P vendor programme for introducing genuinely new products to Amazon: the vendor supplies large quantities upfront with strong advertising investment, and Amazon commits to buying stock at scale, distributing it across fulfilment centres, and supporting the launch with visibility.
Structurally, it trades risk for scale. Amazon gets selection and launch momentum without the usual uncertainty of a new product; the vendor gets the best possible start — broad availability, wide reach, and launch execution support. The vendor carries the sell-through risk, which makes the forecasting and marketing behind an LSPL the whole game.
What each side commits to
The vendor’s side of the ledger: large upfront supply — often many thousands of units into the first purchase order; no-returns terms on those initial quantities, meaning unsold stock is not coming back; significant advertising investment across Sponsored Products, DSP, and Brand campaigns; and full ownership of sell-through risk. In effect, the vendor under-writes the launch.
Amazon’s side: a large opening purchase order, immediate distribution across the fulfilment network (so delivery promises are strong from day one), merchandising and launch support, and the reach of the storefront behind a new selection. For the vendor, that combination is otherwise expensive to buy piece by piece — the programme assembles it in one arrangement.
Why launches are worth this structure — and when they are not
New products normally launch quietly: thin availability, cautious distribution, slow rank accumulation. The programme reverses each of those levers at once — high availability everywhere, a promotional push, and the early sales velocity that rankings reward. A successful LSPL compresses months of ordinary launch momentum into the first weeks.
The discipline is in the forecast. Because the opening PO is large and non-returnable, an overstated demand projection converts directly into unsold, un-returnable inventory. The brands that benefit most run the numbers hard beforehand: category size, competitive intensity, realistic velocity, and an advertising budget sized to the units that need to move — then commit with conviction rather than enthusiasm.
In practice
A vendor launches a new tech gadget through the programme with 10,000 units supplied upfront and a substantial advertising allocation behind Sponsored Products, DSP, and Brand campaigns — fully aware that unsold units of the opening order will not be returnable. The bet works: availability is wide from day one, the promotional push drives early velocity, organic rank builds faster than a normal launch would allow, and Amazon’s selection expands in a category it wants to grow.
How Harpy Media helps
Vendor launch programmes sit at the intersection of our 1P and advertising work: demand modelling before commitment, PO negotiation, and the campaign architecture that carries the launch through its first quarter. Scale is an advantage only when the plan behind it can absorb being wrong.
LSPL FAQ
Is LSPL available to third-party sellers?
No — it is a vendor (1P) programme, run between Amazon’s retail teams and suppliers. 3P sellers can replicate parts of the strategy — large launch inventory, concentrated advertising, early velocity — but without Amazon’s committed buy or the no-returns terms.
What does no-returns mean for an LSPL vendor?
Unsold units from the initial purchase order stay owned by the vendor — Amazon will not return them for credit. Every unit you commit is a unit you have committed to sell or carry, which is why the demand forecast is the single most important document in the whole programme.
How large should the launch buy be?
Large enough to sustain availability and velocity across the full launch window — including the second replenishment cycle — without creating a mountain of unsold, non-returnable stock if demand lands below forecast. The right size lives between those two failure modes, and the modelling is what finds it.
