They paid without leaving the chat
Every redirect a customer has to click through is a chance to lose them — a new tab, a slow page load, a moment of doubt that wasn't there a second ago. Each one chips away at conversion, even when the product and price were never in question.
The alternative is a full journey handled inside a single conversation: browse, pick, and pay, without ever leaving the thread they were already comfortable in.
Zero redirects isn't a minor technical detail — it's a measurable drop-off you avoid entirely just by keeping the whole transaction in one place, from the first "how much is this?" to the final payment confirmation.
