Cost of Goods Sold (COGS) is the direct product cost of the units you sell. Setting it in Dashboardly makes Gross Profit, Net Profit, Margin, and ROI meaningful instead of overstated.
Dashboardly keeps two seller-entered costs separate:
Both values can be stored as dated periods. An Effective Date controls when a value starts, and the value remains active until the next dated value begins. Adding a July cost therefore does not rewrite the cost used for March.
Use a product-level value when all variants share the same cost. A SKU can have its own dated periods when that variant costs more or less.
Dashboardly resolves the dated fallback for a sold unit in this order:
A SKU-specific value overrides the product default only for that SKU. It does not change the other variants.
Open a product in Sales & Profit, then select Manage Unit COG.
The manager shows the currently effective Unit COG and the complete dated history. Use Edit current period to correct the selected period or Add new period to schedule a new cost.
