Every SKU on Blinkit, Zepto or Swiggy Instamart takes physical shelf space in a dark store that could hold something else. The platforms therefore do not list new products automatically. A new SKU goes through an NPI process: the category manager reviews the product, pricing and margin, the catalogue team checks master data, the supply team confirms the brand can fill POs, and the product is listed at a small set of stores as a trial. If it sells at or above the category's velocity benchmark, the listing is widened; if not, it is delisted. NPI is the quick commerce equivalent of getting a retailer to give you a shelf facing, and it happens at the SKU level, not the brand level.
How it works
The sequence brands typically report, and which platform partner teams describe informally, is:
- Proposal: the brand submits the SKU in the partner portal or by email with MRP, cost price, GTIN, dimensions, shelf life, images and a launch plan.
- Commercial review: the category manager checks margin against the category norm and whether the SKU duplicates something already listed.
- Catalogue and compliance: FSSAI licence (for food), legal metrology labelling, barcodes and imagery are validated.
- Trial listing: a small store cluster, often in one city, receives a first PO. The trial length is set case by case; brands commonly cite 4 to 8 weeks.
- Scale or drop: if daily units per store clear the benchmark, more stores and cities are added.
None of the three platforms publishes NPI criteria, trial durations or velocity benchmarks on a public page as of September 2026. Some brands are asked for launch marketing support, such as a discount or a paid placement, to lift trial velocity; these are negotiated terms, not a fixed fee.
Worked example: a beverage brand launches a ₹99 SKU at 25 Zepto stores in Mumbai. Over four weeks it averages 1.6 units per store per day, roughly ₹4,000 a day across the cluster. The category benchmark for the sub-category is 1.2, so the SKU is extended to 120 stores across Mumbai and Pune. A sister SKU at ₹149 averaging 0.5 units per store per day is delisted at the end of the trial.
Why it matters for sellers
Quick commerce demand is concentrated: a few fast SKUs per category take most of the volume and shelf space. Getting through NPI, and clearing the trial, is the difference between a brand being available to millions of app users in a city and being available in two pin codes. It is also the moment when your master data, packaging and supply chain are tested together for the first time.
How to manage it
- Launch with a short list of hero SKUs, not the full range; one or two winners open the door for the rest.
- Complete GTIN, FSSAI, legal metrology and imagery before you propose; catalogue rejections stall NPI for weeks.
- Plan a trial-period push: a modest discount or a sampling offer in the trial cluster lifts velocity when it counts.
- Keep the trial cluster at 100% fill rate; a stock-out during trial reads as low demand.
- Ask for the benchmark you are being measured against, and the store-level sales report, in week one.
