Discounts sell, but profit disappears — where the trap is

A discount is the fastest and most tempting lever on the market: announce a promotion and sales jump immediately. The problem is that growth in sales and growth in profit are two different things. A discount often raises the first and quietly eats the second — while the founder is only watching the revenue figure.

The typical founder mistake: judging the result of a discount only by revenue and unit count, while never calculating the real margin left on each order. "Sales tripled during the promo" — and nowhere is it visible that, at the same time, the profit on each order dropped to less than half.

Where a discount becomes unprofitable — three points

1. A discount that wipes out Contribution Margin

Every discount comes straight out of margin — not out of revenue. If the Contribution Margin on a sale (price minus variable costs: COGS, courier, packaging, advertising) is 45 GEL, a 30% discount on a 100-GEL item wipes out 30 GEL — and margin falls to 15 GEL. Sales may triple, but the profit on each order becomes three times smaller.

• Measure: before and during the promotion — not just revenue, but total margin (Contribution Margin per order × number of orders).

2. A discount that teaches the customer a behavior

The most hidden cost is that constant discounting teaches the customer a harmful behavior: they stop buying at full price and wait for the next promotion. The same thing happens in chat — if the operator answers every "it's expensive" with a discount (Objection Handling), the customer deliberately stalls the conversation to push the price down. The business itself is growing its own unprofitable flow.

3. A discount that artificially inflates AOV

"−20% when you buy two items" raises the average check, but if the second item's margin can't cover the discount, AOV looks great on the dashboard while real profit per order falls. This is exactly the point where "virtual AOV" adds nothing to the business.

What replaces a discount — margin-friendly levers

• Upsell / Cross-sell at full price: offering a high-margin accessory compatible with the core product in chat — the cheapest way to raise AOV.
• Shifting to value, not cutting price: answer "it's expensive" first in the language of quality, warranty and delivery convenience, and only then — a price lever, within controlled limits.
• Planned Markdown on dead stock: discount deliberately only on Dead Stock — where the goal is not margin, but returning frozen capital to circulation.

The typical mistake

A discount is not bad in itself — it is bad when its result is measured only by revenue. A healthy promotion is calculated in advance: we know what margin each discounted sale leaves and whether the total raises or lowers profit. A panicked "sell as much as possible" discount, on the other hand, raises revenue and bleeds the business financially.

Diagnostic question

Do you know exactly what GEL figure the Contribution Margin per order dropped to during your last promotion — and was total profit (not revenue) higher or lower than before the promo? If you actually had this figure, you would no longer make discount decisions by gut feel about revenue.
