I will develop a delivery time calculation widget on a turnkey basis

I develop a delivery time calculation widget on a turnkey basis — from analyzing logistics data to a ready-made block on the website. The customer enters a city or postal code, and the widget immediately shows the date range when the shipment is likely to arrive, taking into account the route from the warehouse, carrier capacity and regional features. Instead of a vague note "delivery 3-7 days" across the entire catalog, the client sees specific dates for their address, which reduces the number of order abandonment cases at checkout.

The widget recalculates the date range immediately when the delivery method changes — by courier, to a pickup point, or by mail — so the customer always sees a current estimate for the selected option. I build the calculation logic on top of your current delivery rules and carrier data, add transit time across regions and account for known bottlenecks like customs clearance or seasonal warehouse congestion so the forecast stays realistic.

I work on the project from start to finish: I analyze the current delivery scheme, design the calculation logic, build the widget itself and test it on real order scenarios before launch. A typical set of work includes:

— city or index input field with autocomplete;
— date range calculation by route and carrier load;
— instant update when delivery method changes;
— neat integration into product card and cart;
— admin panel for configuring base timeframes by region.
