A WhatsApp AI agent for pre-owned watch, handbag and luxury resale shops: answer stock and price enquiries, explain authentication and condition grading, handle sell-to-us and consignment intake with photos, and hand negotiation to the owner
Luxury resale lives on WhatsApp: buyers asking whether a reference is in stock with box and papers, sellers asking what you would give for theirs, both at all hours and from several countries. Each enquiry is worth real money and each takes a specialist's attention, which is exactly why the first reply should not need it.
Quick answer
Give a WhatsApp AI agent your catalogue (reference, year, condition grade, box and papers, price, stock status), your authentication process, condition grading scale, warranty and return terms, shipping and insurance options by region, and a sell-to-us and consignment intake script, and it answers buyer enquiries in seconds in their language, collects seller enquiries with photos, reference, year and papers, and hands over offers, negotiation and authentication to you. It never values an item. ReplyKit runs this from $29 a month.
Buyer enquiries
- Catalogue. One line per item: brand, reference, year, condition grade, box and papers, service history, price, stock status. Update when something sells; the agent stops offering it.
- Authentication. Your process, who authenticates, what guarantee you give. Buyers ask first.
- Condition grading. Your scale defined in words, so "excellent" means the same to the agent and the buyer.
- Terms. Warranty, returns, layaway if offered, payment methods including bank transfer and escrow for high values.
- Shipping. Insured courier options, costs and duties guidance by region; international buyers are a large share, and the agent answers in their language. Currency questions are handled as in currency and pricing questions.
Sell-to-us and consignment intake
- Brand, reference or model, year, whether box, papers and receipts are present, service history.
- Photos: front, back, clasp, serial, papers; the agent asks for each and describes what it sees without judging authenticity.
- Condition in the seller's words and any known issues.
- Whether they want an outright sale or consignment, and your consignment terms quoted from the knowledge base.
- The enquiry lands in your list; you make the offer. The agent must never state a value or a range; put that in the instructions in one line.
Trust and fraud
Resale attracts scammers on both sides. Instruct the agent to quote your verification rules (ID for sellers, in-person or insured-shipment inspection before payment, no payment outside your stated methods), and to hand over anything that deviates. Keep serial numbers of stock out of public replies if you prefer; the agent will follow a rule not to share them. Security practices for the number itself are in protecting your business WhatsApp.
What the dealer keeps
What stays with a person:
- Offers, valuations and negotiation.
- Authentication decisions.
- High-value payment arrangements and escrow.
- Trade and dealer-to-dealer enquiries.
- Disputes and returns.
Everything else the agent handles, and when it is unsure it says so and offers a human rather than guessing; see why the agent says it is not sure.
One honest note before the setup. ReplyKit connects to your number by QR pairing, the same linked-device mechanism as WhatsApp Web. It is live in minutes and needs no Meta approval, but Meta does not sanction automation this way, so a number can be restricted. We enforce limits of 30 replies an hour and 200 a day per number with a warm-up ramp for new numbers, reply to inbound messages only, and recommend a dedicated number rather than your main line. The full picture is in our ban guide.
Starter at $29 a month covers one number, one agent, one website assistant and 1,000 AI replies; Growth at $49 adds two more numbers, five agents and follow-up nudges; the 7-day free trial needs no card. Only the agent's own messages count. Pricing is in USD and the service works wherever WhatsApp does. What it costs in practice.
Frequently asked questions
Can the agent tell a seller what their watch is worth?
No. It collects the details and photos and hands over for your offer. It never states a value.
Can it confirm authenticity from photos?
No. It describes the photos and leaves authentication to you.
Does it answer international buyers?
Yes, in their language, with shipping and insurance options by region from your notes.
Can it quote stock prices?
Yes, from your catalogue, and it stops offering items you mark sold.
How does it help with fraud?
It quotes your verification and payment rules consistently and hands over anything that deviates.
