Both ask the customer one question: do you still want this cash-on-delivery order? A call asks it out loud and gets a keypress. A WhatsApp message asks it in a chat and waits for a tap or a reply. Here is where each one works better, without the sales pitch.
Keypad confirmation call
An automated call reads out the store name, order number and COD amount in Hindi or English. The customer presses 1 to confirm or 2 to cancel, and the answer is written back to the store.
Best for: Reaching every buyer, including people who don't use WhatsApp, and getting a definite yes or no quickly
WhatsApp confirmation message
A template message with the order details and Confirm / Cancel buttons. The customer answers whenever they open the chat.
Best for: Buyers who live on WhatsApp, low-cost first contact, and sending more detail such as the product, address or a pay-online link
Generic comparison of the two methods, not of any particular vendor
| What matters | Keypad call | WhatsApp message |
|---|---|---|
| Works without WhatsApp | ||
| Works on feature phones | ||
| Customer must read | ||
| Interrupts the customer | Yes, a ringing phone | No, answered at leisure |
| How fast you get an answer | During the call, or after retries | Whenever the chat is opened |
| Can show product, image or address | ||
| Pay-online link in the same step | ||
| Main cost driver | Call attempts and minutes | Messages sent, by message category |
| Pre-approval needed | Calling rules and DND hygiene | Approved message template |
| Write-back to store | Built in (tag, note, cancel) | Depends on the tool you use |
| Languages | Hindi and English voice | Any language you can write |
A call reaches anyone with a working phone number, including feature phones and people who don't use WhatsApp or keep it on a different number. A WhatsApp message reaches only numbers registered on WhatsApp, and only helps if the customer opens the chat.
The flip side: many people ignore calls from unknown numbers, especially during work hours, while they will happily tap a button in a chat later. Neither channel reaches everyone.
We are not going to quote you a percentage. The cost of either method comes down to a few numbers you already know or can measure:
Example arithmetic (replace with your own numbers):
cost per answered order = (cost per attempt × attempts per order) ÷ share of orders that answer
value per answered order = share of answers that are cancels × your cost per RTO
If the value is higher than the cost for a channel, that channel is paying for itself. Run the numbers for both channels with your real rates and response rates. The COD confirmation call cost calculator and the COD RTO calculator do this arithmetic with inputs you can change.
An answer only helps if your team sees it before packing. With our confirmation calls, the result is written back to the order: a tag such as COD-CONFIRMED, a note, or a cancellation, depending on your platform. With WhatsApp, check whether your tool updates the order in your store or only shows the reply in an inbox someone has to read.
Many stores use both channels: a message first, then a call to customers who haven't replied, or the other way round. Our confirmation calls are triggered by your store or your own system, so you can send us only the orders still unconfirmed. An automatic WhatsApp fallback inside our product is not available yet.
Honest guidance, including where WhatsApp wins
If...
Most of your buyers are in tier-2 and tier-3 towns, or many don't use WhatsApp
Then...
Keypad call
A ringing phone reaches people who never see a chat message, and a Hindi call is easy to answer with one key.
If...
Your buyers are mostly metro and WhatsApp-first
Then...
WhatsApp message
They are likely to answer in the chat, and a message usually costs less per contact than a call.
If...
You want to show the product, confirm the address or push a pay-online link
Then...
WhatsApp message
A keypad call can only ask yes or no. A chat can carry images, text and links.
If...
You need the answer before the courier pickup cut-off
Then...
Keypad call
A call gets the answer during the call itself, with retries on your schedule, instead of waiting for the chat to be opened.
If...
You want both reach and low cost
Then...
Use both
Send the message first and call only the orders that are still unconfirmed, or call first and message the unreachable ones.
