A campaign surfaces a fixed offer. A mandate gives the AI negotiating authority up to a defined limit. Both fire at contextually appropriate moments — triggered by what the customer is discussing or by data from their account. Neither fires indiscriminately. ## How it works Commercial rules are evaluated on every message. When a rule's trigger condition is met, it becomes active and the AI is given permission and guidance to use it in the response. Every use is logged in the audit trail. ## Rule types ### Campaigns A campaign is a fixed, time-bound offer. The AI presents it as configured — no variation, no negotiation. Use campaigns for: * Promotional discounts with a hard end date * Seasonal offers * Upsell offers tied to specific product contexts ### Mandates A mandate gives the AI negotiating authority within defined boundaries. You set the maximum concession — for example, up to 20% discount or one free month — and the AI negotiates within that range based on the conversation context. Use mandates for: * Retention conversations where flexibility improves save rates * Upgrade incentives where the right offer depends on customer context ## Trigger types | Trigger type | Description | | --------------- | ------------------------------------------------------------------------------------------------------------- | | Topic-triggered | Fires when the conversation topic matches a defined intent — e.g. "customer is asking about cancellation" | | Data-triggered | Fires when customer CRM data meets defined conditions — e.g. customer has been active for more than 12 months | Rules can combine both trigger types — a retention mandate that fires only when a long-tenure customer raises cancellation, for example. ## Relationships Journey stages define which commercial rules can fire within that stage — ensuring offers only appear in the right context. Every commercial rule use is logged — what was offered, what was accepted, what concession was made. Topic triggers use semantic matching to identify when a rule should fire — the same mechanism as knowledge retrieval. ## Configuration ### Creating a campaign Go to **Campaigns** in the portal → **New campaign**. Define: * **Offer** — what is being offered, in plain language the AI can use * **Trigger** — topic or data condition that activates the campaign * **Active dates** — when the campaign is live * **Journey scope** — which journey stages permit this campaign (optional) ### Creating a mandate Go to **Mandates** in the portal → **New mandate**. Define: * **Negotiating authority** — the maximum concession the AI can offer * **Guidance** — how the AI should approach the negotiation * **Trigger** — topic or data condition that activates the mandate * **Budget tracking** — optional total budget limit across all uses ## Reference | Concept | Description | | ------------- | ---------------------------------------------------------- | | Campaign | A fixed, time-bound offer presented as configured | | Mandate | Negotiating authority within defined boundaries | | Topic trigger | Activates when conversation topic matches a defined intent | | Data trigger | Activates when customer CRM data meets defined conditions | | Concession | The discount, credit, or benefit offered within a mandate |
