Set the analysis boundary
A valid ecommerce gross margin case begins with a defined population of orders. Calculate gross margin after product cost, fulfillment, marketplace fees, payment fees, and refunds. The result is a measure of that population only.
The source trail for ecommerce gross margin supports this point: mark the entity, product, region, and cutoff used in the order ledger; those labels determine whether another run is comparable.
Evidence for each input
In a reconciled ecommerce gross margin case, the store operator should approve the definition of Gross sales. Use the same currency for gross sales. Flag conversions applied to Gross sales before comparing it with Refunds and allowances.
The sign convention for Refunds and allowances must match the equation. Exclude duplicates from refunds and allowances where applicable. Retain reported and adjusted Refunds and allowances whenever Product cost also uses an adjustment.
Within the selected merchandise population, Product cost needs a cutoff. Confirm the sign assigned to product cost. Keep evidence for Product cost separate from documentation supporting Fulfillment cost.
Ask whether Fulfillment cost includes reversals or cancellations. Apply the documented definition of fulfillment cost. Reconcile the Fulfillment cost cutoff before interpreting movement in Marketplace and payment fees.
The working file for ecommerce gross margin indicates that document any allocation used to produce Marketplace and payment fees. State any allocation included in marketplace and payment fees. Explain why Marketplace and payment fees and Gross sales belong to one population.
Interpret the number with its denominator
When discussing ecommerce gross margin, compare the figure only with a case using the same inclusion rules. An unlabeled benchmark is not a reliable control.
In a reconciled ecommerce gross margin case, archive the baseline before editing Marketplace and payment fees. A side-by-side result is easier for the store operator to review.
Compare ecommerce gross margin across segments only after each segment applies the same rules to Gross sales and Marketplace and payment fees.
A small percentage in ecommerce gross margin may represent a large absolute population. Keep the count or value beside the rate.
The arithmetic in plain form
Against the defined ecommerce gross margin base, the supporting rows expose the calculation path. Ecommerce gross profit subtracts all entered variable order costs and refunds from net sales. Tie each row back to the order ledger.
Test data for the model
The default dataset contains Gross sales = $680,000; Refunds and allowances = $46,000; Product cost = $280,000; Fulfillment cost = $62,000; Marketplace and payment fees = $74,000.
