If you’reselling on Shopify, your shoppers could have last-minute questions right before they proceed to checkout. Maybe they want to know whether a jacket fits true to size, when their order would arrive, or whether a sold-out size is coming back. Without a way to ask and receive a quick reply, they could abandon their cart altogether. A floating WhatsApp button in the corner of their screen as they browse lets them know they’re one tap away from starting a conversation in an app they already use daily. There’s no form to fill out and no new account to create, which means a shopper who would have left with an unanswered question can get a response that turns into a sale.
