How ordering on WhatsApp works
An order on WhatsApp follows one clean path, and every step lives in the same thread: the customer browses your catalog, adds items to an in-chat cart, confirms the order, pays by in-chat UPI, receives an automatic GST invoice, and then gets order-status and delivery updates as it ships. A human can drive it from the shared inbox, or an AI order-taking agent can run the conversation for you.
Catalog → cart → confirm → UPI → invoice → updates
Nothing hands the customer off to a separate website or app. The enquiry, the payment, the invoice and the tracking all happen where the buyer already is — which is exactly why WhatsApp orders convert better than a link to an external checkout.
What's inside the ordering system
Each part is a real WatEase capability, and they connect into one flow — so an order captured in chat ends in a paid, GST-invoiced, trackable sale rather than a message you still have to key in somewhere else.
Shareable catalog & storefront
Publish your products as a catalog customers can browse right in the chat, backed by a shareable storefront link you can drop into a bio, an ad, or a broadcast — so an order can start from anywhere and land in WhatsApp.
In-chat cart
Customers add items and build a cart inside the conversation — quantities, variants, running total — without bouncing to a separate website. The order is assembled where the buyer already is.
In-chat UPI checkout
Collect payment in the same thread via a checkout link backed by your own gateway — Razorpay, PhonePe or Paytm — so the customer pays by UPI without leaving WhatsApp and the money settles into your account.
Automatic GST invoice
When an order is paid, a GST-compliant invoice is generated automatically with the correct tax breakup and delivered back in the chat — no manual invoicing step for you or your customer.
Order-status & delivery updates
Keep the buyer informed after checkout — confirmation, dispatch and delivery updates flow back into the same WhatsApp thread, so the order stays visible from enquiry through fulfilment.
AI order-taking agent
Optionally let an AI agent run the conversation: it reads the request, builds the cart, answers product questions, and takes the order to in-chat UPI checkout with a GST invoice — handing off to a human when it should.
Catalog, in-chat cart, UPI checkout, GST invoicing, order updates and AI order-taking are all available today on the paid plans as of June 2026.
One thread, from enquiry to paid order
The reason a WhatsApp ordering system beats a "chat, then send a payment link elsewhere" setup is that it closes the loop. Because WatEase owns the commerce backend — catalog, UPI / Razorpay / PhonePe / Paytm checkout in chat, GST invoicing, order updates — the same conversation that captured the order also collects the money and confirms it, with nothing falling between three disconnected tools.
Enquiry → cart → in-chat UPI checkout → GST invoice
The customer asks, builds a cart, pays by UPI in the same thread, and gets a compliant invoice back automatically — then delivery updates as it ships. Order captured, money in the bank, books in order, all inside WhatsApp.
Built for India
The ordering system speaks the way Indian businesses sell: UPI-first checkout via Razorpay, PhonePe or Paytm, GST-compliant invoices, and Meta conversation costs shown in rupees with quality-rating -aware sending so an aggressive broadcast never burns your number. Consent handling is DPDPA 2023-aligned, data sits in ap-south-1 (Mumbai), and it all runs on the official WhatsApp Business API.

Frequently asked questions
What is a WhatsApp ordering system?
A WhatsApp ordering system is a way for customers to place and pay for an order entirely inside a WhatsApp chat — no separate app or website checkout. The customer browses your catalog in the conversation, builds a cart, confirms the order, pays via in-chat UPI, and receives a GST invoice and order-status updates in the same thread. WatEase runs this on the official WhatsApp Business API, so the whole flow — catalog, cart, UPI checkout, invoice, delivery updates — happens where your customer already is, optionally with an AI order-taking agent handling the conversation.
How do customers place an order on WhatsApp?
They start a chat — from your shareable catalog link, a WhatsApp button on your site, a Click-to-WhatsApp ad, or a broadcast. From there they browse products, add items to an in-chat cart, and confirm. The order can be assembled by your team in the shared inbox, or by an AI order-taking agent that understands the customer's request in their own words, builds the cart, and answers product questions. Either way the customer never leaves WhatsApp to complete the purchase.
How do customers pay for a WhatsApp order?
Payment happens in-chat via UPI. WatEase sends a checkout link backed by your own payment gateway — Razorpay, PhonePe or Paytm — so the customer pays by UPI (or card/netbanking) without leaving WhatsApp, and the money settles into your account. Because checkout is native to the order flow, the same conversation that captured the order also collects the payment and confirms it.
Do I get a GST invoice automatically?
Yes. When a WhatsApp order is paid, WatEase generates a GST-compliant invoice automatically and can deliver it back in the chat — no manual invoicing step. The invoice carries the correct tax breakup so your books and your customer's records stay clean, which matters for B2B and any GST-registered buyer.
Can an AI take the order automatically?
Yes. WatEase includes an AI order-taking agent that can run the conversation for you: it reads the customer's message, assembles the cart, answers product questions, and guides them to in-chat UPI checkout with a GST invoice — without a human on every message. It hands off to your team in the shared inbox the moment judgement is required, so you get automation with an override rather than a black box. AI order-taking is available today on the paid plans.
How much does a WhatsApp ordering system cost in India?
WatEase starts on the Growth plan at ₹1,999/month for the full commerce + messaging stack — catalog, in-chat cart, UPI checkout, GST invoicing and order updates — with 0% markup on WhatsApp messages, so Meta conversation charges pass through at cost while many competitors add 20–25%.
