How QCMM Resolves Overlapping Promotions and Locks the Checkout Price

QCMM does not stack multiple scheduled Promotions on the same purchase. It evaluates eligible sale prices, selects the lowest result, uses ordering to resolve ties, and preserves the accepted Promotion in the purchase snapshot.

Promotions Do Not Stack

When more than one scheduled Promotion is eligible, QCMM does not add their discounts together. Each eligible Promotion produces its own candidate sale result.

Lowest Eligible Price Wins

QCMM compares eligible Promotion results and uses the lowest resulting price. If eligible Promotions resolve to the same result, configured ordering provides the tie-breaking rule.

Checkout Locks the Commercial Result

The Promotion accepted for the transaction is captured in the purchase/billing snapshot. A later Promotion edit, reordering, expiration, or unpublish action must not retroactively change the earlier purchase.

Test Overlaps Intentionally

When campaigns overlap, test the overlap period with an eligible account and Plan. Confirm the expected Promotion wins and that the order summary reflects one Promotion result rather than stacked sale discounts.
