A complicated checkout process is one of the biggest conversion killers, so keeping it smooth should be your first priority. First, offer guest checkout; forcing users to create an account adds unnecessary friction. Keep forms short by only asking for essential information, and provide multiple payment options and Buy Now, Pay Later (BNPL) services. Display trust signals like SSL certificates, secure payment icons, and clear refund policies, to reassure customers. An order summary also prevents cart abandonment by eliminating unexpected surprises. Finally, consider using exit-intent popups to offer a last-minute discount before visitors leave. The easier and more transparent the process, the fewer abandoned carts you’ll see.
