Compare sales channels using contribution per completed order after their actual costs. Include marketplace commissions, advertising, promotions, payment costs and the staff work needed to fulfill the sale. Gross order value tells you what customers spent; contribution tells you what is left to run the business.
An owned DROPS shop gives you a mobile catalogue, checkout, order status and customer accounts on a direct ordering route. That creates another channel you can measure and develop. It still has costs, including your agreed platform price, acquisition work and operating time. A useful comparison gives each channel a fair share of its own costs.
Put both channels on the same basis
Choose an observation period, reporting currency and definition of a completed order. Remove tests and cancellations consistently. Decide how refunds, delivery income and tax are treated before comparing figures. A tax-inclusive marketplace total beside a tax-exclusive shop total will give you a false answer immediately.
Separate new-customer orders from repeat orders where your records support it. A channel attracting new customers can have a different cost structure from a channel serving people who already know the shop. Do not assign the entire cost of acquiring a customer to every later order.
Build the contribution table
These figures are illustrative and do not describe any named marketplace or DROPS pricing. Both orders have a merchandise value of 80 units, excluding tax.
| Per completed order | Marketplace | Own shop |
|---|---|---|
| Merchandise revenue | 80 | 80 |
| Goods cost | −40 | −40 |
| Marketplace commission | −12 | 0 |
| Payment cost not already included above | −2 | −2 |
| Packaging and delivery subsidy | −6 | −6 |
| Allocated channel advertising | −8 | −10 |
| Allocated platform/channel cost | −1 | −3 |
| Variable staff handling | −3 | −2 |
| Contribution after listed costs | 8 | 17 |
The direct order leaves 9 more units in this scenario. That is a result of these inputs, not a universal claim that one channel is always cheaper. If direct acquisition cost rose by 12 per order, its contribution would fall to 5. Replace every row with your actual agreement and records.
Check whether a commission already includes payment handling before adding it again. Likewise, a delivery fee charged to the customer and paid to the delivery provider must be treated consistently on both sides.
Allocate advertising without claiming certainty
If a channel campaign costs 240 and you assign 30 completed orders to it under a stated reporting rule, the allocation is 240 ÷ 30 = 8 per order. The arithmetic does not prove that the campaign caused all 30 purchases.
Keep the attribution method visible. A customer may discover you in one place and order somewhere else later. Some direct orders arrive through word of mouth; some marketplace customers were already loyal to the business. When the source is unknown, retain an unknown group instead of forcing every order into a flattering channel.
Use campaign attribution and incremental sales to separate recorded attribution from a causal sales claim.
Look beyond the average basket
Repeat the calculation for smaller orders, typical baskets and larger orders. Fixed handling costs can consume a much larger share of a small basket. A channel that looks healthy on its average may contain a group of orders that needs a higher minimum, a clearer delivery charge or a different offer.
Then compare total contribution and capacity. A lower-contribution channel may still bring worthwhile volume into spare capacity. During a busy period, the same orders may displace stronger sales or create service delays. Neither decision should be based on a fee percentage alone.
Keep payout timing separate from profitability. Money arriving later can create a cash squeeze even when the order contributes positively. The operating cash guide helps examine that second question.
Know what every order leaves behind. See DROPS and inspect the direct ordering experience, order records and customer account tools. Bring your own channel-cost table, then judge how an owned shop fits your business.
