The ultimate COD order confirmation app for Shopify

Hold and Verify

Unverified cash-on-delivery checkouts are put on hold instantly inside Shopify. This holds up the printing of shipping labels and prevents fulfillment before customer verification.

Deliver Verification Prompt

WhatSort delivers a WhatsApp message featuring Confirm, Cancel, or Advance Payment options. The buyer interacts with the quick-reply button on their phone.

Release to Fulfillment

Once verified, the order is updated with a 'WhatSort-Confirmed' tag in Shopify, releasing it to your packing and shipping lines. Auto-cancellations handle unresponsive buyers.

RTO is the hidden leak in cash-on-delivery operations

Every time a courier returns an undelivered parcel to your warehouse, you pay the forward shipping fee, the return shipping fee, and endure inventory lock-up. In cash-on-delivery markets, average RTO rates hover around 30% to 40%.

By using a dedicated Shopify WhatsApp automation flow, you catch undeliverable orders before they leave your warehouse.

RTO Mitigation Math

Identify undeliverable COD orders instantly

Every single failed COD delivery costs you double shipping fees and inventory lock-up. Many buyers make impulse orders with fake numbers or incomplete addresses.

WhatSort catches this early. Our system pauses order processing for incomplete addresses, automatically texts the customer a secure link to update it, and gathers explicit one-tap confirmation before you dispatch the parcel.

How much RTO does it cut?

On average, merchants using WhatSort reduce Return-to-Origin (RTO) rates on cash-on-delivery orders by 35% to 45%. By validating phone numbers and filtering out buyer second-thoughts, you avoid paying double delivery costs.

Can I collect advance deposits to verify COD?

Yes. You can configure confirmation templates to include a custom payment link. This allows buyers to pay a small partial deposit (e.g., shipping cost) via UPI, cards, or wallets to verify intent, with the remaining balance due on delivery.

Does it support bulk confirmation operations?

Yes. You can manage all pending COD orders inside the WhatSort dashboard, allowing you to bulk-verify, bulk-message, or bulk-cancel orders in a single click.

Which regions and carriers does this work for?

WhatSort is carrier-agnostic because it integrates directly with Shopify. It functions globally, and is heavily used in COD-dominant markets across India, the Middle East, and Southeast Asia.

Can I set auto-cancellation timers?

Yes. You can define rules to automatically cancel or flag COD orders if the buyer fails to respond to confirmation prompts within 12, 24, or 48 hours.

What happens when an address is flagged as incomplete?

If our system detects a missing street, house number, or postal code, it places the order on hold and sends a WhatsApp prompt asking the buyer to update their address details on a secure form.
