Should I offer live chat during checkout?

As a Shopify store owner in the competitive e-commerce landscape, I've been wrestling with a critical conversion optimization challenge. My checkout process, which should be the most crucial part of my sales funnel, feels like a potential customer dropout zone. I've noticed that visitors sometimes hesitate, get confused, or simply abandon their cart at the last moment. Is this happening because they have unanswered questions? Are they experiencing uncertainty that could be resolved with immediate support? I'm constantly thinking about reducing friction and providing a seamless purchasing experience. Live chat during checkout seems like a potential solution, but I'm not entirely sure. Will it genuinely help convert more customers, or could it potentially distract and complicate the checkout process? I need a strategic approach that doesn't just add another element to my page, but genuinely supports my customers' decision-making process. The stakes are high—every abandoned cart represents lost revenue, and in today's competitive market, I can't afford to lose potential customers at the final hurdle. I'm looking for a nuanced, data-driven perspective that can help me understand whether live chat is a conversion booster or just another potentially disruptive feature.
