Promo architecture on quick commerce: who funds the discount

Four wallets can pay for the same discount

On Blinkit, Zepto, and Instamart, the price a shopper sees is funded by one of four sources. Trade margin built into your PO price. A brand funded consumer offer that shows as a strike-through against MRP. A platform funded cart offer or coupon. Or a bank offer, paid for by the card issuer. Brand teams open the app, see 24 percent off, and assume it is theirs. Sometimes it is. Sometimes it is three offers stacked on one SKU and nobody modelled the stack before it went live.

Promotion architecture is the discipline of deciding which wallet pays, at what depth, on which SKU, for how long. Skip it and the 20 percent off tag becomes permanent. The platform then treats the discounted number as your working price, competitive scrapes anchor to it, and your next correction reads as a 25 percent hike to both the algorithm and the shopper.

Build a ladder, not a habit

Give every SKU a defined set of rungs and a rule for time spent on each.

• Rung zero. No offer, clean MRP. Every SKU should spend at least eight weeks a quarter here.
• Rung one. 8 to 12 percent, always on, funded from trade margin. Table stakes in most quick commerce categories.
• Rung two. 15 to 20 percent in seven day bursts, tied to a real reason: a platform event, a seasonal peak, a new variant landing.
• Rung three. 25 to 30 percent, reserved for launch trial and clearance only, capped at four weeks and no more than twice a year per SKU.

The rule that saves the money is the cooldown. After a rung three burst, the SKU goes back to rung zero or one for at least two weeks, and you read what happens. If units in the cooldown fall below the pre-promo baseline for a fortnight, the burst did not buy new households. It pulled purchases forward from people who were already buying, and it taught them to wait for the next tag.

Combo SKUs beat deeper percentages

A 2-pack listed as its own SKU with its own EAN is the most underused lever in Indian quick commerce. Price it 8 to 12 percent below two singles. You get a higher ticket, one pick instead of two, better contribution per order, and a price point no competitor can place a like for like comparison against. Your single pack MRP stays intact for every other channel.

For consumables on a 30 day cycle, coffee, shampoo, protein, pet food, the multipack does something more valuable than lifting AOV. It buys out the next purchase occasion. A shopper holding 60 days of supply is not comparing brands in week three. Watch single pack units after the combo launches. A 10 to 15 percent shift from single to combo is healthy substitution. A 40 percent shift means the combo is priced too cheap and you are discounting your best customers.

Guardrails that stop the slow margin leak

• Parity. Keep the shopper facing price within 2 percent across the three main platforms in the same week. Category teams scrape competitors daily, and a 15 percent gap comes back as a claim against your next PO or a demand for matching support.
• No blind stacking. Before agreeing to a platform event, get the funding split, the SKU list, and the exact dates in one written mail. Verbal splits become your cost at settlement.
• Never run maximum ad spend and rung three depth on the same SKU in the same week. You will not know which lever moved units, and you will be asked to pay for both next quarter.
• One promo owner. If the category manager can call three people in your team for support, they will call the one most likely to say yes.

The monthly promo review

Build one sheet per platform with six lines: gross sales at MRP, platform margin, brand funded offer spend, ad spend, net revenue, and promo as a percentage of net revenue. Steady state for most FMCG brands lands between 6 and 10 percent of net revenue on promo, sitting on top of a 22 to 35 percent margin. Above 15 percent, you are renting volume and the rent is due monthly.

Then read two ratios. First, promo depth against unit uplift, per SKU, per burst. If 25 percent off produces a 30 percent unit lift, you have bought turnover and given away margin. Look for bursts where a 15 percent tag moved units 50 percent or more, and repeat only those.

Second, share of units sold on any offer. If more than 70 percent of your volume moves at a discount for three consecutive months, your MRP is fiction and your next annual negotiation starts from the discounted price rather than the printed one. Repairing that takes two quarters of holding rung zero and accepting some volume loss on purpose, which is a decision only a founder can sign off. Better to never need it.

None of this is about being stingy. Quick commerce rewards brands that show up with a clean price story and a reason for every tag. The brands in trouble are not the ones that discounted. They are the ones that never decided who was paying.
