Sales are rising. Is profit per order rising too?

A product sold for SAR 100 can leave less contribution than one sold for SAR 80. The difference may sit in product cost, marketplace fees, delivery, advertising, and returns. A revenue report shows what customers paid; it does not necessarily bring together every cost required to win and fulfill those orders. If you want to know whether selling more of an item under the same conditions is worthwhile, begin with a completed order rather than a headline sales total.

Amazon Saudi Arabia's pricing page says referral fees depend on product category and fulfillment costs depend on the route used to ship the order. Storage and optional services such as advertising can add other charges. Do not apply one referral-fee percentage to every item or carry a cost from one product or program into another. Check the current fee page and your account terms when doing the calculation. The purpose here is a method, not a universal fee table. ^[1]

Define the result before you calculate it. In this article, order contribution is the amount left from the net sale after product cost, marketplace fees, fulfillment, advertising, and an allowance for returns. It is not the company's net profit. Salaries, rent, and other overheads require a separate accounting view. Use the same definition across every comparison and keep revenue and cost on a consistent accounting basis.

Start with the amount earned from the product after a discount. Include the effect of a coupon or any delivery charge that you subsidize. Subtract what it cost to buy or make the item, then the marketplace referral fee, storage or fulfillment charges where relevant, and your shipping cost under the chosen program. Allocate advertising cost to the orders the campaign was meant to win rather than comparing a full month of ad spend with one day's sales. Estimate return cost using your own history and update it as actual outcomes arrive.

Here is a hypothetical SAR 100 sale: product cost SAR 50, marketplace fees SAR 12, fulfillment SAR 10, advertising SAR 8, and a returns allowance of SAR 5. The costs total SAR 85, leaving SAR 15 in contribution. The numbers illustrate the arithmetic only. They are not a fee schedule for Amazon or another marketplace, and they do not cover every tax or accounting item. The accompanying figure shows the same allocation so that each deduction from the selling price can be checked.

Avoid counting the same cost twice. When you put an actual return cost against an order, do not also charge that order a separate expected-return allowance for the same event. If a marketplace has already deducted fees before paying a settlement, do not use the payout as your starting revenue and subtract those fees again without reconstructing the original sale. Systems record these amounts differently, but each cost should have one clear place in the calculation.

Use the same illustration to test a SAR 10 reduction. If the sale price falls from SAR 100 to SAR 90 and every other cost stays fixed in this hypothetical case, contribution drops from SAR 15 to SAR 5 per order. You now need three discounted orders to earn the contribution of one original-price order. That is before any extra fulfillment workload or pressure on stock. Some real marketplace fees vary with price, so recalculate with your product's actual charges before running an offer.

Order count alone can make that offer look successful. At the original price, 100 orders at SAR 15 contribution leave SAR 1,500. At the discounted price, even 200 orders at SAR 5 leave only SAR 1,000 under the same assumptions. Orders doubled while total contribution fell. This does not mean discounts are always wrong. Clearing ageing stock may be worth a lower margin, for example. The calculation makes the cost of that objective visible instead of allowing a sales increase to conceal it.

Run the same test on advertising. In the illustration, SAR 23 remains before the SAR 8 advertising cost. If the business needs at least SAR 10 contribution per order, it can afford no more than SAR 13 in allocated advertising cost under the unchanged assumptions. That is not a recommended bid or a universal acquisition-cost target. It is a ceiling derived from one hypothetical product. Your own ceiling changes with price, category fees, return rate, and required margin.

A product can carry a similar price in two marketplaces and still leave a different amount after costs. Referral fees, delivery charges, ad spend, and returns can differ. Give each product in each marketplace its own row for the same reporting period, using the same definition of revenue and cost. A brand-wide average can hide a popular item with weak contribution behind less popular items with stronger margins.

Imagine the example product leaves SAR 15 in the first marketplace. In a second marketplace, fees might be SAR 3 higher, fulfillment SAR 3 lower, and advertising SAR 4 lower. If everything else is unchanged, contribution becomes SAR 19. This is another arithmetic illustration, not a description of either marketplace's actual fee schedule. Its value is in showing why a stock-allocation decision should follow a product-level comparison, not a sales ranking.

Do not move all stock as soon as one channel shows a better calculated margin. Watch the real order count, how long the product remains available, replenishment time, and whether your team or the marketplace can ship on time. A strong margin on a handful of orders may not compensate for lost sales elsewhere. A promising margin on paper can also shrink if returns rise or a larger ad budget is needed to sustain the expected volume.

Sale date and settlement date are different. A fee adjustment or return may arrive after the order is recorded, changing the contribution you first estimated. Keep the order date and settlement status together, and distinguish estimated contribution from contribution after final charges arrive. Do not compare one week of new orders with one week of older settlements as though they describe the same selling period.

Reconcile estimates with actual outcomes regularly. If the returns allowance is smaller than actual losses, products will look more profitable than they are. If you allocate all spending on a campaign to one item while it also helped sell other items, that item's result will be understated. Weekly decisions do not require a fully closed company income statement, but they do require visible assumptions, a consistent method, and corrections when better data becomes available.

Start this week with one high-volume product. Calculate contribution from completed orders, then recalculate it after a discount you are considering or a possible increase in advertising. Set the minimum contribution the business needs and ask how many additional orders would be required to offset the reduction per order. If final fees or returns data are still thin, limit the trial and review the result before applying the change across the catalog.
