Estimated delivery date on the product page: why it increases conversions

“When will it arrive?” is one of the last questions a customer asks before paying. If they can't find the answer on the product page, they look for it in the cart, then at checkout, and sometimes they leave before getting there. In this article I show you why it's worth displaying the estimated delivery date right on the product page, how to calculate it correctly and what I learned building such a system for ALURA. Why the delivery date matters before checkout Most online stores write “delivery in 2-5 business days” somewhere in the footer or only at the shipping step. For the customer, that creates two problems: They have to do the maths. If it's Thursday evening, “2-5 business days” could mean Tuesday or the following Thursday. Uncertainty turns into postponing. They find out too late. If they discover at checkout that the product arrives after the event they're buying it for, they drop off exactly where you've already paid for the traffic. A concrete date (“Arrives Thursday, 16 October”) answers the question before it comes up. It's simple information, but it changes how the customer perceives the risk. What problem it actually solves At ALURA, one of the most frequent obstacles to completing an order was the lack of clarity about delivery. Customers didn't know when the product would arrive or whether it was available right away. The result: uncertainty, abandoned carts and extra questions to support. Once the estimate became visible throughout the buying journey, from the product page to checkout, the experience became more transparent and the order completion rate went up. In short, a correctly displayed delivery date: reduces abandonment caused by uncertainty; reduces “where is my order?” questions to support; builds trust , especially in busy periods when customers expect delays; creates natural urgency : “Order within the next 2 hours to get it on Thursday.” How to calculate the estimated delivery date correctly The hard part isn't the display, it's the…
