Retailers do not stock the highest-margin product. They stock the one that earns the most per square foot per month — which is a different question entirely.
A brand manager thinks in margin percentage. A kirana owner thinks in rupees per month per foot of shelf.
Those produce different rankings, and the gap explains most failed trade schemes.
Consider two products competing for the same space. One earns ₹4 a unit and sells 200 units a month. The other earns ₹12 a unit and sells 30. The first earns ₹800, the second ₹360 — and the first is the one the retailer will reorder, whatever the margin percentage says.
So the question is never "what margin should I offer". It is "what will this earn on the shelf it displaces".
Before any of this, get the arithmetic straight, because it is quietly wrong in a lot of trade conversations.
Margin is profit as a share of the selling price. Markup is profit as a share of cost. A supplier offering "25% markup" is offering a 20% margin. If you build a plan around 25% margin and only mark up 25%, you fall short on every unit.
The Markup to Margin Converter does the conversion, and the Selling Price from Margin Calculator works backwards from a target — dividing by (1 − margin), not multiplying by (1 + margin), which is the common error.
You can put value into the retailer's hands three ways, and they cost you differently:
1. Invoice margin. Lower the price you bill. Simple, transparent, and permanent — hard to take back later.
2. Free goods. A 10+1 scheme: they pay for 10, receive 11. Costs you one unit at your cost; worth roughly 9% to the retailer at their selling price. Cheaper for you, and it puts stock on the shelf that has to sell through.
3. Cash discount for early payment. Costs you a percentage but buys back working capital. See the Cash Discount Calculator — on 2/10 net 30 terms, a 2% discount to get paid 20 days early is expensive money if you look at it annualised, so use it deliberately.
Most distributors reach for invoice margin because it is easiest to explain. Free goods usually delivers more perceived value per rupee spent, with the important caveat below.
Free goods work when the SKU sells. On a slow line, a 10+1 scheme means the retailer now has eleven units of something that was not moving — and you have converted your dead stock into their dead stock.
They will remember. The next scheme you offer gets more resistance, and you have spent goodwill along with the goods.
The test before offering free goods: would this retailer reorder this SKU at full price within a month? If not, the scheme is not a growth tactic, it is inventory disposal.
When a scheme stacks — 20% + 10% + 5% — the temptation is to describe it as 35% off.
It is not. Each discount applies to the price left after the previous one, so ₹1,000 becomes ₹800, then ₹720, then ₹684. That is a 31.6% effective discount.
This matters in both directions: you are giving less than you think, and the retailer is receiving less than they heard. Run the chain through the Trade Discount Ladder Calculator before you commit to it verbally.
Illustrative numbers, to re-run with your own.
Say a product has an MRP of ₹100. You sell it to the retailer at ₹80 and buy it at ₹68.
Now add a 10+1 scheme. The retailer's effective cost per unit drops to about ₹72.70, so their effective margin rises to roughly 27% — while your invoice price never changed. That is the leverage free goods gives you, and why it is often the better instrument.
The Retailer & Distributor Margin Calculator lays this out across all three levels.
For where margin sits among the other things that decide a distribution business, see how to calculate distributor ROI.
Two distributors offering identical margin do not compete equally, and the difference is usually not price.
What else the retailer is weighing:
This matters strategically because margin is the most expensive lever you have — every point comes straight off your own. Several of the others cost operational discipline rather than money.
Most schemes buy purchases the retailer would have made anyway, a few weeks earlier. Two design choices avoid it.
Tie the offer to range, not volume. A free case for stocking five SKUs builds shelf presence. A free case for buying fifty units of one builds a pile in their godown that suppresses next month's order.
Cap it per outlet. Without a cap, your largest retailers absorb most of the budget on lines they were already buying, and your growth outlets — the ones you actually wanted to move — see little of it.
A worked example, to re-run with your own numbers. Suppose 100 outlets, and a scheme costs you ₹40,000 in free goods at your cost. If it produces ₹2,00,000 of additional billing that stays — meaning next month does not dip below trend — that is a defensible spend. If billing dips by ₹1,50,000 the following month, you spent ₹40,000 to move ₹1,50,000 of purchases four weeks earlier.
The month-after number is the whole test, and it is the one nobody looks at.
Margin percentage is an abstraction. Three things land better:
None of that requires giving more margin. It requires knowing the retailer's business well enough to talk about it in their terms.
The questions that come up in every trade negotiation.
It varies sharply by category rather than by a single number — fast-moving staples run thin because they turn constantly, while personal care and impulse lines carry more. The useful framing is not the percentage but the rupees per unit multiplied by how often it sells. Ask what comparable shops earn on the shelf space you want.
Usually, for two reasons. It costs you at your cost price while the retailer values it at their selling price, and it puts extra units on their shelf which pulls through faster. The condition is that the SKU actually sells — free goods on a slow line is just your dead stock moved to their godown, and they will notice.
Because margin percentage is not what a retailer optimises. A 25% margin on something that sells twice a month earns less than 10% on something that sells daily, and it occupies the same shelf. High margin is often a signal of low velocity rather than a benefit.
