How Can E-commerce Businesses Reduce Failed COD Deliveries Using AI Calls?

Short answer: call every cash-on-delivery order before it ships. An AI voice agent rings the buyer within minutes of the order, confirms they meant to place it, checks the address and landmark, and asks when someone will be home to pay — in the buyer's own language. Orders the buyer cancels, or that can't be confirmed, are held instead of shipped.

Why COD orders fail

Most failed COD deliveries come down to a few causes: an impulse order the buyer no longer wants, an incomplete or wrong address, nobody home with cash, or a fake order. Every one of them is cheaper to catch on a phone call before dispatch than on the doorstep after you have paid for shipping both ways.

How it works, step by step

1. An order comes in. Your store or backend calls the outbound call API with the order details — name, items, address, amount.
2. The agent calls the buyer. In the buyer's language, with the order filled in: "You ordered two kurtas to Kothrud, Pune — shall we send them?"
3. It confirms the address. The agent reads back the address, asks for a landmark if it is thin, and notes any correction.
4. It asks about delivery. When someone will be home, and whether cash will be ready — or whether the buyer would rather pay online.
5. The outcome goes back to you. Confirmed, cancelled, address changed, call back later or unreachable — sent to your systems with a signed webhook, with the transcript, so the order is shipped, held or updated.
6. WhatsApp backs it up. A buyer who can't talk can confirm on WhatsApp instead, and the agent there remembers the call.

Buyers who don't answer

• Smart retry calls back a busy line within minutes and an unanswered one an hour or more later — never a buyer who declined.
• Callbacks: "call me after six" becomes a scheduled call inside your calling hours.
• A rule for the rest: decide in your store what happens to an order nobody confirms — hold it, cancel it, or ship it prepaid only.

The same agent after dispatch

Once the order ships, the same agent can call before the delivery attempt to make sure someone is home, and after a failed attempt to rebook it — the jobs covered on the logistics page.

What you need to start

A phone number, a webhook from your store, and a short script. The e-commerce page has the full call flow, and tool calling explains how the agent reads and writes your order data during the call.
