Upsell & Cross-sell
Post-purchase upsell with holdout proof
The order just confirmed — the warmest moment to recommend what goes with it, and every dollar of lift is proven against a control group.
What it does
The minutes after a purchase are the highest-intent window a brand ever gets, and most companies spend it on a transactional receipt. The agent uses that window to recommend complementary products and services — accessories in the receipt thread, a lesson pack to go with new gear, a contextual offer the day after a service visit. And because post-purchase upsell is usually a guess dressed up as a result, every eligible customer is randomly split against a holdout: the revenue you see is the lift the agent actually created, not the purchases that would have happened anyway.
How it works
- 1Trigger. an
order_confirmedevent arrives, or a time-based follow-up window opens (the day after delivery, after a service appointment). - 2Decision. the agent picks the complementary product or service from the catalog, the order's contents, and the customer's memory — then a judge gates the message for relevance and policy. A slice of eligible customers is held out and receives nothing.
- 3Action. the recommendation lands in the receipt thread or as a follow-up on the customer's channel (chat, email, in-app, SMS) with a one-line reason tied to what they just bought; purchases run through the client's own secure checkout hand-off.
- 4Follow-through. accepted and declined offers are written back to memory; if the customer returns the order or opens a complaint, any queued upsell is cancelled. Lift is reported as the delta between treated and holdout groups.
Configuration
How the agent is wired for this use case.
order_confirmed event from the OMS, or a time-based follow-up window opening (day after delivery, after a service visit)- OMS / commerce platform · read order contents; subscribe to delivery, service-visit, and return/complaint events
- Product & service catalog · resolve the complement matched to the order
- CRM / memory store · read customer memory and consent; assign holdout vs treated; write back accept/decline and report lift
- Messaging channel · deliver the recommendation in the receipt thread or as a channel follow-up
- Hosted checkout · hand off the purchase to the client's own secure payment page

Guardrails
judge gating on every unprompted message; randomized holdout assignment; frequency caps per customer; automatic suppression on returns, refunds, or open support issues
Metrics it moves
- attach-rateup, by putting the right complement in front of the customer at peak intent
- aovup, measured per order across treated customers
- revenue-per-conversationup, and reported as holdout-proven incremental lift rather than gross attributed revenue
