Short answer: WhatsApp commerce uses the WhatsApp Business API so customers can browse a catalogue, ask a question, and pay by UPI without leaving the conversation. For Indian consumer and distribution businesses, that single-screen checkout regularly outperforms a classic storefront on repeat and considered purchases. The part that decides whether it lasts is the back-office sync.
Why the channel works here
Two things stack. Open rates on WhatsApp sit far above email, so a message actually gets read. And in-chat UPI checkout removes the steps where storefront funnels leak: no account creation, no address form, no redirect to a payment page that fails on a patchy connection.
There is a third, less-discussed reason. Conversation handles objections. A buyer who would have abandoned a cart asks "does this fit a 2019 model" and gets an answer in forty seconds. No storefront widget replicates that.
The failure mode: a second set of books
Here is where most WhatsApp commerce projects go wrong. The channel gets set up, orders start arriving, and someone copies them into the ERP by hand. Within a month you have two versions of stock, two versions of the customer, and an invoice sequence with gaps in it.
The channel is not the project. The integration is:
- Catalogue publishes out of your ERP, so a price change happens once.
- Stock is checked against the real figure before an order is accepted, which is what stops you from selling something you do not have.
- Orders post straight into the order table, with the customer matched or created, and the invoice raised in the system your accountant uses.
- Support conversations become tickets, so a promise made in chat is visible to whoever handles it next.
- Payment status flows back, so nobody ships against an unconfirmed UPI collect request.
Build those five and WhatsApp is a channel. Skip them and it is a parallel business somebody reconciles by hand on Sunday.
Consent and template discipline
WhatsApp rates the quality of your number, and that rating governs how many messages you are allowed to send. Broadcasts to people who did not opt in are the fastest way to have that rating cut, and the damage is not quickly undone.
Capture consent explicitly, keep the record, and keep template messages genuinely useful. Order confirmations, dispatch notices and delivery updates are welcome. Weekly promotional broadcasts to a purchased list are how a number becomes unusable.
Where it fits against a storefront
It is not a replacement. A storefront carries discovery, search visibility and large catalogues; WhatsApp carries conversion, support and repeat orders. The strongest setup we build runs both, writing into one back office, with the storefront acquiring and the chat converting and retaining.
That works the same way whichever ERP sits behind it, which is the point — the channel should be replaceable, and the system of record should not be.
