COGS Glossary

TermDefinition
COGSCost Of Goods Sold -- the total cost to produce, ship, and prepare one unit of your product for sale. Used to calculate profit and margin.
Unit CostThe expense associated with manufacturing a single product item, which can be entered directly or derived by dividing total expenditure by unit quantity.
Cost PeriodA defined time range during which a specific unit cost applies. Start and (optionally) end dates determine the valid window for applying that cost.
Start DateThe first day a particular cost is valid. Required for all cost entries.
End DateThe last day a cost applies. Optional -- leaving it blank makes the cost period open-ended.
Cost ElementA specific component of the total unit cost, such as manufacturing, shipping, or packaging. Not tracked individually in SellerLegend -- for your own context.
Simple ViewA COGS input mode requiring only Unit Cost and Date Range. Ideal for speed and straightforward costing.
Detailed ViewA COGS input mode supporting extra fields like Units, Total Paid, Currency, Exchange Rate, Provider, and Notes.
CurrencyThe 3-letter ISO code (e.g., USD, GBP, EUR) representing the currency in which the cost was paid.
Exchange RateConversion rate from the original currency to the marketplace's currency. Optional in Detailed View.
UnitsThe number of units included in a shipment or cost batch. Used to derive unit cost from Total Paid.
Total PaidThe total amount paid for a batch of units. Used in combination with Units to auto-calculate unit cost.
Provider(Optional) The supplier or vendor who fulfilled the cost period. Used for traceability.
Notes(Optional) Additional free-text context about the cost period -- e.g., shipment ID, discount received, promo reasons.
Bulk UploadA method of entering or updating multiple COGS entries via Excel or CSV file, instead of one-by-one in the UI.
PropagationCopying a COGS configuration from one EU marketplace to another. Does not auto-convert currencies.
Open-ended PeriodA cost period without an End Date. SellerLegend treats it as "currently active" until another period starts.
OverlapWhen two cost periods for the same SKU have intersecting date ranges. This is not allowed and will cause upload failure.
GapA time range between two cost periods where no cost is defined. SellerLegend will assume $0 cost and overstate profit during that time.
