Conversational AI can help a shopper understand an existing offer, but it should not invent reasons to buy. Its useful role is narrower: retrieve current catalogue and policy information, ask clarifying questions, state what is unknown and hand the conversation to a person when judgement or an exception is needed.
Answer from current commercial sources
Price, stock, shipping time, warranty and return rules should come from approved systems at request time, not model memory. Show the source timestamp when freshness matters. If a feed is unavailable or two systems disagree, say so and offer human handoff rather than choosing the more persuasive answer.
A useful assistant might ask whether delivery is needed before a date, then compare only products meeting that constraint. It can explain documented differences and link to policy. It must not invent scarcity, social proof, certifications or compatibility, and should not present paid placement as independent advice.
Design honest unknowns and handoff
Define answerable questions, required source fields and escalation conditions. Returns outside standard policy, high-value orders, accessibility needs and contradictory data are common handoff cases. Give the person the conversation, sources and unresolved question.
Review samples for factual accuracy, omitted limitations, inappropriate pressure and correct escalation. Product and policy owners need a correction path. A polished answer built on an outdated catalogue is still wrong.
Evaluate impact without claiming causation
Compare similar traffic and periods where possible. Track completed orders, cancellations, returns, complaints, human review cost and gross margin—not only chats or apparent conversion. Segment by channel and product mix. Promotions, seasonality, stock, advertising and site changes can all affect purchasing.
An association between assistant use and orders does not prove causation. A controlled rollout or credible comparison group is stronger, but results still need context. Do not announce expected return or conversion before measurement.
For reliable stock inputs, see inventory synchronization and forecast evaluation. For permissions and handoff, use the responsible-agent checklist.
