Why Does an Ecommerce Product Page Show an Incorrect Delivery Estimate?

A delivery estimate may be based on default location, old carrier data, warehouse stock, cutoff time, or a cached calculation. Customers can see one date on the product page and another after entering their address.

What to check

Compare location assumptions, warehouse and inventory, carrier service, order cutoff and timezone, holidays, cache age, and checkout calculation. Test the same item at multiple destinations and order times.

Recommended next step

Use transparent estimate assumptions and keep product-page and checkout calculations aligned. Update carrier calendars and validate estimates after changing fulfillment rules.
