Control Coupon Interaction with Promotions and Site Credit

QCMM lets administrators define how a Coupon interacts with scheduled Promotion pricing and, separately, whether Site Credit may also be used. These are independent commercial rules and should be tested together before launch.

Coupon and Promotion Modes

Configure the Coupon for the intended relationship with scheduled Promotion pricing: allow it to combine with the sale Promotion, apply it against regular-price behavior only, or let the Coupon and Promotion compete so the better resulting price is used.

Site Credit Is a Separate Decision

The Coupon’s Site Credit rule is independent of its Promotion interaction. A campaign can allow or disallow Site Credit according to the Coupon configuration rather than assuming that Promotion compatibility decides credit compatibility.

Why This Matters

Without deliberate interaction rules, a campaign can discount more than intended or reject a combination the business meant to allow. Define the commercial policy first, then configure QCMM to match it.

Test the Matrix

• Coupon with no active Promotion.
• Coupon with an eligible Promotion.
• Coupon when Site Credit is available.
• Coupon + Promotion + Site Credit together.

Confirm the order summary and final billing snapshot match the selected interaction policy in every supported case.
