COD is the lifeblood of Indian e-commerce. It removes the payment barrier for first-time customers who don't trust online transactions. But that trust comes at a steep cost to sellers — one most founders only understand after losing significant money.

This guide covers every major COD problem with actionable solutions, systems, and scripts you can implement today. We built this from 8 years of running Kallos Vanity — and from the lakhs we lost before we understood what was happening.

RTO is the single biggest profit killer in COD. When a customer refuses delivery, your product comes back — but not without cost. Most sellers only count the return shipping. The real loss is far worse.

What causes RTO?

• Customer ordered on impulse and changed their mind
• Customer not available at delivery address on multiple attempts
• Wrong address or phone number provided at checkout
• Customer placed multiple orders from different sellers — accepts one, rejects others
• Fraudulent orders placed by competitors or bots
• Product expectation mismatch (looks different from the Instagram ad)

The real cost of every RTO

How to reduce RTO

Fake orders waste packaging, shipping, and ad spend. Each one is money out of your pocket with nothing in return.

Dimension and weight disputes

This is one of the most common ways sellers lose money silently. Courier companies use automated volumetric machines after pickup. If your box is even slightly dented or pressed during transit, the machine reads it as larger than it is — and the extra amount is quietly deducted from your wallet. No warning. No approval. Just gone.

• Photograph every order before dispatch — front, side, and top. Timestamp the photos.
• Maintain a master dimension sheet: product name, box size (L×W×H), dead weight, volumetric weight.
• Set your dimensions correctly at the time of booking — never leave it blank.
• Review weight discrepancy reports weekly. Dispute anything above 10% variance.
• Ask your account manager to whitelist your top SKUs with pre-approved dimensions.

Lost shipments — the 40% problem

COD creates a cash flow gap. You spend money on ads, production, packaging, and shipping — but you only receive payment 7–15 days after delivery. If there is an RTO, you receive nothing. Here is what that actually looks like:

How to close the gap

NDR (Non-Delivery Report) is what happens when a delivery attempt fails. How you manage NDRs directly determines your final RTO rate. Most sellers ignore them — and that is where they lose.

• Show the COD fee clearly at checkout — transparency nudges customers toward prepaid
• Offer free shipping only on prepaid. Even ₹40 savings moves customers
• For repeat customers who have paid COD before — offer them a loyalty prepaid discount
• Tell your Instagram audience openly to order prepaid if they trust you. It works.

Start with the highest-impact actions first. These are in order of priority.
