Clearly prioritize discount codes, partner codes, and special prices

What sequence prevents conflicting discounts, partner codes, and special prices?

Conflicts are eliminated through a clearly defined priority and explicit combination rules for each code and price type. After each application, the system rechecks the protection thresholds and logs the initial price, rule versions, and result.

Explainable pricing path

Cross-check: "Double discount"

A partner price is already its own price base and cannot be further reduced by a general promotional code. The engine recognizes both rules, applies only the higher-priority partner price, and explains why the promotional code was not considered.

Scope of validity

1. All price rules are recorded in a decision table with their rank, exclusion, validity, and threshold.

2. A server-side engine calculates the final price based on the unchanged initial price and valid rules.

3. Pairwise combinations, expiration, reuse, and manipulated order are automatically tested.

Rule rank

• Explainable pricing path – The initial value and any effective changes remain traceable for approval and support.

Double discount

• Double discount – Two rules reduce the same price base, even though only one should apply.

• Outdated special price – A personal exception remains active after expiration or product change.

• Frontend sequence – The user interface determines the final price based on the click sequence, instead of querying a central engine.

Conclusion: Clearly Prioritize Discounts and Special Prices

Price rules need a business hierarchy before they are combined technically. An explainable price path prevents random or manipulable results.
