Can AI Answer Product Questions, Check Availability, and Take Orders on WhatsApp?

The job usually reads like this: "We need AI to answer product questions and check availability on WhatsApp, take simple orders, and tell customers when the item they wanted is back."

All four of those work today with WhatsApp AI Pro — including live stock checks, which used to be this article's honest exception until the inventory connectors shipped in August 2026. One boundary remains (in-chat checkout), and you should know it before buying anything. Here's the breakdown.

Product and Availability Questions: Answered From Your Catalog

The agent answers from company information you give it — and loading it takes about 10 minutes: chat the facts in, upload a file, or paste your website and let it extract the catalog, prices, and policies (the AI Replies tutorial shows all three paths).

From then on, "do you have the red one?", "what's the price for 200 units?", "do you ship to Brazil?" get answered from your data — in the customer's language, 90+ supported, at 2 a.m. Every reply passes an accuracy check against the knowledge base before sending, which is what stops the classic AI failure of inventing a price or a shipping promise.

And when "availability" means live stock, connect an inventory source: an Excel/CSV file on your computer, a Google Sheet, your Shopify store, or your WooCommerce store. From then on, "is it in stock?" and "can you supply 40?" are answered from a query at the moment the customer asks — not from a snapshot you uploaded last week. Every stock statement must cite that query (answers that can't are blocked), you review inventory drafts before they go out, and approval re-checks the live number at the moment you tap it. The live inventory tutorial walks through all four sources in about ten minutes each.

For catalog businesses — where "availability" means we make this, in these variants, at this MOQ — the knowledge base alone is exactly right, and you don't need a connector at all.

Recommendations From the Conversation, Not a Catalog Dump

Because the agent reads the whole thread, "suggest something for a beach wedding" or "what goes with the model X I bought last month" gets an answer based on what the customer already said — their sizes, past questions, budget hints — matched against your catalog. It's the difference between a salesperson who remembers the conversation and a link to your product grid.

Taking a Simple Order

The agent can carry an order conversation end to end: confirm the variant, quantity, delivery address, and preferred terms, and assemble that into a clear summary. What happens next is a handoff by design — the order lands with a human (via the morning queue, Team Mode, or the Enterprise Inbox) who confirms payment and enters it into whatever system you actually invoice from.

It does not process payments, generate payment links, or write into an order management system. For a $30 impulse purchase with in-chat checkout, a Shopify-integrated cloud bot is the better shape. For orders where a human confirms anyway — wholesale, custom, B2B — the AI doing the conversation and a person doing the commit is the workflow most teams want.

"Tell Me When It's Back": Restock Notifications

This works today as a win-back broadcast: when the item is back, you pick the conversations that asked about it, tell the AI why you're reaching out, and it writes a personal message to each customer — referencing what they actually asked — while skipping anyone it judges shouldn't be disturbed. The broadcast tutorial covers the safety rails.

Note the shape: it's you triggering the broadcast when stock arrives, not an automated watcher firing on an inventory webhook. Manual trigger, AI-written personal messages. On a regular WhatsApp number that's also what keeps you out of spam trouble — these are replies to people who asked, not a blast.

What This Setup Doesn't Do

No in-chat checkout. No payment collection, no payment links, no order writes into external systems. A human commits the order.
No general ERP sync (yet). Live stock covers spreadsheets, Google Sheets, Shopify, and WooCommerce today. If your inventory lives in an ERP, export it to a spreadsheet the AI reads live — most teams already have that export.
A desktop app runs it. macOS/Windows, connected to your existing number by QR code — keep a machine on for 24/7 coverage.

Frequently Asked Questions

How does the AI know my products and prices?

You load company info once — by chatting it in, uploading files, or pasting your website URL for automatic extraction. The agent answers only from that, and each reply is checked against it before sending.

Can it really check stock?

Yes — live, since August 2026. Connect a spreadsheet, Google Sheet, Shopify, or WooCommerce store and stock questions are answered from a query at the moment they're asked. The safety model matters as much as the data: the AI can only claim availability it can cite from that query, you review inventory answers before they send, and approving one re-verifies the live number first. Setup for each source is in the live inventory tutorial.

Can customers complete a purchase inside the chat?

No. The AI confirms variant, quantity, and address, then hands the assembled order to a person who takes payment and enters it in your system. There is no in-chat payment step.

Can it notify customers automatically when stock arrives?

Semi-automatically. You trigger a win-back broadcast when the item is back; the AI writes an individual message to each customer who asked, and skips people it shouldn't disturb. There's no automatic inventory-webhook trigger.

Does it work in my customers' languages?

Yes — it detects the customer's language and answers in it, 90+ languages, including transcribing and translating voice notes. Same knowledge base, no per-language setup.

What does it cost compared to API-based commerce bots?

$49/month flat (or $499/year), no per-message or per-contact fees, on your existing WhatsApp number. API-based commerce platforms charge a platform fee plus Meta's per-conversation fees — see our cost calculator to model a real month.

Try it on your own catalog: download WhatsApp AI Pro, paste your website into the knowledge base, and ask it your ten most common product questions in Suggest mode. $49/month flat, 7-day money-back guarantee.
