Check a discount before it turns more orders into less money

Calculate what the discounted order leaves after its included costs, then compare that with the normal order. A higher order count is not enough to judge an offer. You may be spending more time and using more stock to leave less money for the business.

This guide uses fictional prices, costs and fee rates. It is a decision worksheet, not a recommended discount, tax calculation or profit guarantee. Replace every assumption with your own records before using the result.

Give the offer one clear purpose

Write what you want the promotion to achieve: move a particular slow-selling batch, introduce a collection, or encourage a larger relevant order. Avoid “increase sales” as the only objective—it does not tell you which costs or outcomes to compare.

Decide which products and customers qualify, how long the offer runs and what ends it. Check the chosen storefront's actual coupon rules before promising minimum spends, combinations, exclusions or usage limits. A marketing plan is not proof that the checkout supports it.

Shopify's retail discount guidance also frames discounting around objectives and margin. The worked examples below are our own; no conversion result from another retailer is assumed to apply to your store.

Calculate the normal order first

Suppose a product normally sells for ₹600. Its included cost is ₹380, covering the material, labour allowance, packaging and other costs you chose to include. For illustration only, assume a fee of 3% of the product price and no other charges.

Call this a remainder, not automatically net profit. Advertising, returns, taxes or overhead may be missing from the model. If your actual provider uses capped, fixed or differently based fees, calculate those rules instead of copying the percentage.

Apply the discount to the revenue—not to the cost

A 15% discount changes the selling price from ₹600 to ₹510. Making the product still costs the assumed ₹380. The hypothetical fee becomes ₹15.30, leaving ₹114.70.

That is ₹87.30 less per fulfilled unit than the normal ₹202 remainder. The discount reduced the price by 15%, but it reduced this model's remainder by about 43.2%.

To produce the same total remainder under these unchanged assumptions, you would need about 1.76 times as many fulfilled units, or roughly 76.1% more. This is arithmetic, not a forecast that the offer will generate those orders. It also assumes capacity, costs and fulfilment quality do not deteriorate at the higher volume.

If you already have a full production schedule, check whether those extra discounted orders would displace full-price work. An offer can create a capacity problem even when each individual order leaves a positive amount.

Compare a bundle separately

A bundle is not automatically a better deal for the seller. Price the actual contents and handling.

Two normal units in the example leave ₹404 in total. Suppose you instead offer the pair for ₹1,100. Their combined included cost is ₹760, but assume the shared packaging genuinely saves ₹20, reducing it to ₹740. The hypothetical 3% fee is ₹33. The bundle leaves ₹327, which is ₹77 less than two normal units.

The bundle may serve a deliberate purpose, but “two items in one order” does not establish its profitability. Verify the packaging saving and delivery cost. Heavier or bulkier parcels may change the result, and customers may choose the bundle instead of two purchases they would otherwise have made.

Include everything the promotion changes

Run a second pass over the costs. A free gift has a cost even if it was already on your shelf. Free delivery is funded somewhere. Extra packing work still takes time.

• Add campaign advertising and creative costs where applicable.
• Include extra packaging or fulfilment work caused by the offer.
• Check how partial returns, cancellations and refunds affect the calculation.
• Confirm whether discounts can combine, and test the resulting total.
• Keep the same tax treatment in both baseline and offer calculations.

Do not count tax collected for remittance as money you can keep. Obtain appropriate accounting advice for the tax and reporting treatment of your offer; this worksheet does not establish it.

Write the customer-facing terms clearly

State the products included, the benefit, any minimum spend and the end condition in words a customer can understand. Do not advertise an inflated “before” price to make the saving look larger. Keep evidence for any price comparison you make.

Check the offer on a phone with an eligible bag, an ineligible bag and the boundary value around any threshold. Confirm the displayed total before payment. A banner and a coupon setting can disagree even when each looks plausible in isolation.

If the checkout cannot enforce an important restriction, do not rely on customers overlooking it. Change the offer or explain the limitation before launch.

Keep a one-page promotion record

After the campaign, compare completed orders and the costs actually incurred. Keep cancellations and refunds visible. Avoid calling every order during the offer incremental: some customers might have bought anyway, and other campaigns or seasonal demand may have changed at the same time.

If the original cost base is uncertain, start with the handmade pricing worksheet. Check current platform pricing for actual charges, and ask for setup guidance before promising a discount workflow you have not tested.
