Defining COGS Via the User Interface

SellerLegend uses period-based COGS accounting, allowing you to define different unit costs for products across various time ranges. This ensures profit calculations reflect the cost of goods at the time the product was sold.

Navigation

Access the COGS editor by:

1. Visiting Products List
2. Selecting a product
3. Clicking the kebab menu (three dots)
4. Choosing Enter Cost Of Goods

Alternatively, click the COGS column directly in the Products List.

Timeline Understanding

The COGS Timeline View displays:

• Existing cost periods
• Gaps where costs aren't defined
• Prevents overlapping date ranges

Entry Modes

Feature	Simple View	Detailed View
Total Cost Per Unit	Required	Required
Currency	Optional	Required
Units in Shipment	--	Required
Provider/Notes	--	Optional

Adding Cost Periods

1. Click + Add New Period
2. Enter the start date
3. Enter the end date (optional for open-ended periods)
4. Enter the cost per unit
5. Optionally fill in currency, exchange rate, and notes

Important Considerations

• SellerLegend recalculates affected reports immediately upon saving, with propagation taking up to 15-20 minutes for large accounts
• COGS inform Profit & Loss Reports, dashboards, and settlement analysis
• Overlapping date periods are not permitted
• For multiple products, use bulk upload via Excel for efficiency

Best Practices

• Implement future-dated costs to avoid manual updates
• Maintain continuous coverage without gaps
• Switch to Detailed View for audit trails requiring vendor tracking
