# COD Confirmation: AI Call vs WhatsApp vs IVR

> Which COD confirmation cuts RTO for Indian D2C stores: WhatsApp, IVR or an AI voice call? Reach, cost per order, languages and the combined flow.

**For most Indian D2C stores, the best COD confirmation setup is WhatsApp first and an AI voice call
for anyone who doesn't reply**, both before the courier pickup. WhatsApp is cheapest per message.
An IVR call handles simple "press 1" confirmations. An **AI voice call** reaches people who ignore
messages, understands spoken Hindi and regional languages, and can take an address change in
conversation, so more orders end with a clear confirmed or cancelled answer before you ship.
This is Edesy's [COD verification](https://edesy.in/ai-voice-assistant/use-cases/cod-verification) use case.

This guide compares the three methods on reach, cost per order and what each misses, then shows the
combined flow and how to connect it to your store.

> **Want every COD order confirmed by phone, automatically?** See [COD order confirmation calls](https://edesy.in/cod-order-confirmation): the customer presses 1 to confirm or 2 to cancel, and the answer is written back to your store. Hindi and English.

## Why confirm COD orders at all

Every COD order that is refused at the door, or can't be delivered, comes back as return-to-origin
(RTO). You pay forward shipping, return shipping and packaging, and the stock is stuck in transit. A
confirmation step before dispatch catches the orders that were placed by mistake, as a test, or with a
wrong address. Use our [COD and RTO calculator](https://edesy.in/tools/cod-rto-calculator) to see what RTO costs you
at your own rates, and the [shipping rate calculator](https://edesy.in/tools/shipping-rate-calculator) for the
courier charges on both legs.

## The three methods compared

| | WhatsApp message | IVR call ("press 1") | AI voice call |
|---|---|---|---|
| How it works | Template message with Confirm / Cancel buttons | Recorded call, keypad reply | Two-way spoken conversation |
| Reaches people who ignore messages | No | Yes | Yes |
| Understands spoken replies | - | No, keypad only | Yes, Hindi, Hinglish and regional languages |
| Handles "change my address" | Only with extra flows | No | Yes, in the same call |
| Answers questions ("when will it arrive?") | Only with a chatbot | No | Yes, simple ones |
| Clear outcome recorded | When they tap a button | When they press a key | Confirmed / cancelled / address change |
| Relative cost per order | Lowest | Low | Low (per answered minute) |
| Best for | First attempt, every order | Simple, high-volume yes/no | Non-responders, high-value orders, address issues |

No single method is best on its own. Each one catches people the previous one misses.

## How a keypad confirmation call works on Edesy

The "press 1" column above is what Edesy's [COD order confirmation calls](https://edesy.in/cod-order-confirmation)
do, connected to your store:

1. **Your store sends the new COD order** by webhook. Prepaid and already-confirmed orders are skipped.
2. **We wait a short delay** (2 minutes by default) and call inside your calling hours
   (9 am to 9 pm IST by default). Orders placed at night are called the next morning.
3. **We check the order is still open** just before dialling, so cancelled orders aren't called.
4. **The customer hears the order number and COD amount** in Hindi or English and presses 1 to
   confirm or 2 to cancel.
5. **The answer is written back** as a tag, note, status or cancellation, depending on your platform.
6. **No answer?** Up to three attempts by default (30 minutes, then 2 hours apart), after which the
   order is marked unreachable.

Every line of the script is editable. A custom store or backend connects today through a signed
webhook ([custom store API](https://edesy.in/cod-order-confirmation/custom-store-api)); for Shopify and WooCommerce
we set it up for you during the pilot. The full sequence, defaults and outcomes are in
[how COD confirmation calls work](https://edesy.in/cod-order-confirmation/how-it-works).

## The combined flow

1. **Order placed (COD).** Send the WhatsApp confirmation template immediately.
2. **Wait 2-4 hours**, or until your pickup cut-off approaches.
3. **Not confirmed yet? AI voice call**, in the customer's language:
   > Namaste {{name}} ji, main {{store}} se ek automated call kar rahi hoon. Aapne {{product}} order
   > kiya hai, cash on delivery, {{amount}} rupaye. Kya main aapka order confirm kar doon?
4. **Capture the outcome** as data: confirmed, cancelled, address change (with the new address),
   call back later.
5. **Update the order**: ship confirmed orders, cancel the cancelled ones, fix addresses, and retry
   "call back later" once before the cut-off.
6. **Still no answer after retries?** Decide by order value: hold high-value orders, ship low-value ones.

More ready-made scripts are in our [Hindi AI calling scripts](https://edesy.in/blog/hindi-ai-calling-scripts-outbound-2026)
post.

## Connecting it to your store

The flow is the same for Shopify, WooCommerce or a custom store:

1. **Trigger:** a new COD order fires a webhook from your store, or an automation tool (Zapier,
   Make, n8n) watches for new orders.
2. **Call:** the automation sends the customer's phone number and order details (name, product,
   amount, address) to the voice agent's API as variables. See the
   [trigger-call API](https://edesy.in/docs/voice-agent/api/trigger-call).
3. **Capture:** the agent's data fields record the outcome and any new address after the call.
4. **Write back:** the call result is posted to a webhook, and your automation updates the order
   status or tags it in the store.

Edesy also has a built-in order-status template to start from. For Shopify-specific options, see
[Shopify COD verification](https://edesy.in/shopify-cod-verification), and for D2C playbooks, read
[voice AI for COD verification](https://edesy.in/blog/voice-ai-cod-verification-d2c-brands-2026).

## What it costs per order

On Edesy, AI calls are billed **per started minute at Rs 4-6 per minute** depending on your prepaid
top-up, and **unanswered calls are free**. A COD confirmation usually finishes in under a minute:

- **About Rs 4-6 per answered confirmation call**
- Only orders that did not confirm on WhatsApp get a call, so the cost per order across all orders is lower

Keypad confirmation calls on Edesy are priced separately: pay as you go from a prepaid wallet, and
share your monthly COD volume for pricing.

Compare either cost with the forward and return shipping on one RTO order on your courier. If one call
prevents one RTO in every few calls, the maths usually works; our
[COD and RTO calculator](https://edesy.in/tools/cod-rto-calculator) lets you plug in your own numbers.

## Practical tips

- **Call before the pickup cut-off**, inside a daytime calling window.
- **Match the language to the region**: Hindi-English in the north, the state language elsewhere.
- **Keep it under 45 seconds**: confirm, handle address changes, done.
- **Listen to the first 30 recordings**: product names and amounts are where voices trip up.
- **Say it is automated** and offer a callback from your team for complaints.

## Frequently Asked Questions

### What is the best way to confirm COD orders in India?

Use WhatsApp first, because it is cheap and most customers reply, and follow up with an AI voice call for orders that are not confirmed within a few hours. The call reaches customers who ignore messages, can handle address changes in conversation, and records a clear confirmed or cancelled outcome before you ship.

### Is an AI voice call better than IVR for COD confirmation?

An IVR asks the customer to press 1 or 2, which works for simple yes/no confirmations. An AI voice call understands spoken replies in Hindi and regional languages, can take a new address or delivery time, and answers simple questions, so fewer calls end without a clear outcome.

### How much does a COD confirmation call cost?

Edesy's keypad COD confirmation calls are pay as you go from a prepaid wallet; share your monthly COD volume and we'll share pricing for it. The AI voice agent is billed separately, per started minute, and unanswered calls are free. Either way, compare the cost with one return-to-origin shipment on your courier.

### Can the COD confirmation call update the order in my store?

Yes. Your store or an automation tool sends the order details to the voice agent's API, the agent captures confirmed, cancelled or address change as data, and the result is posted to a webhook that updates the order status in Shopify, WooCommerce or your order system.

### When should the confirmation call happen?

Within a few hours of the order and before the courier pickup cut-off, during a daytime calling window. Calling too late means you ship before you know; calling at night annoys customers.
