What Are Effective Dates in Product Cost?

Effective dates let you define when a cost becomes active, so Analytics can calculate profitability correctly across time.

The Logic

Costs are evaluated as-of the selected date (or within the date range you analyze).
If you backdate a cost change, Analytics recalculates profitability for prior periods where that cost should apply.
If you set a future effective date, Analytics will apply the cost starting on that date.

Key Value Pillars

Historical accuracy: Profit reflects what costs were at the time
Change tracking: You can align profitability with real supplier changes
Planning: Future effective costs support forecasting and proactive optimization

Pro-Insight

⚠️ When your supplier changes cost mid-quarter, set the effective date to the supplier’s change date. This prevents confusing “margin drops” caused by applying today’s cost to past sales.
