By 2010, India’s internet penetration was rising steadily. Mobile phones were proliferating. A growing urban middle class was curious about online shopping. The ingredients for an e-commerce revolution were present.

And yet, online retail was barely moving.

The reason was not technology. It was not product selection, or pricing, or even the quality of websites. It was something far more fundamental: the trust required to hand over money before receiving anything in return.

In a country where fewer than 5% of adults held credit cards, where net banking was unfamiliar to most, and where consumer protection for online transactions was nascent at best, the act of paying upfront for a product you could not see or touch felt genuinely risky. Not irrationally so. Genuinely so.

Sachin and Binny Bansal understood this. And they made one decision that changed everything.

The Small Shift

Cash on delivery — COD — was Flipkart’s answer to the trust gap. The mechanics were simple: a customer places an order online, the product is delivered to their door, and payment is made in cash only once the customer has physically received and inspected it.

In principle, this shifted all the financial risk of the transaction from the buyer to the seller. Flipkart was now the party going first. They would dispatch the product, absorb the logistics cost, and only collect payment at the end — if the customer chose to accept the delivery.

Operationally, this was formidably complex. It required building or partnering with a last-mile delivery network capable of handling cash transactions across thousands of Indian pin codes, in towns and cities with wildly varying infrastructure. It required cash reconciliation systems, return processes for refused deliveries, and training delivery personnel to act as trusted financial intermediaries.

The Bansals did it anyway, because they understood something that balance sheets could not easily capture: the size of the market that had been waiting, afraid to move.

What This Behaviour Was Really Saying

Every business interaction sends a signal about who is trusted and who bears the risk. In traditional retail, the customer pays after touching and inspecting the product — trust is built through physical experience. In the early e-commerce model, the customer paid before any experience at all. That asymmetry was not irrational to refuse.

Cash on delivery rebalanced the relationship. It said, structurally: we trust you enough to send this before you have paid us. And you do not have to trust us until it is in your hands.

This is the Gestalt principle in its most direct form: a small behavioural commitment, repeated at scale, that signals something far larger than the transaction itself. COD was not just a payment option. It was a declaration of whose experience the company was designed to protect.

It also had a second-order effect that the Bansals perhaps did not fully anticipate at launch: it made Flipkart deeply motivated to get the delivery right. Every dispatched product that came back as a refused delivery was a cost. The incentive to deliver well, on time, in good condition, was baked into the model. The behavioural shift created an alignment of interests that a pre-payment model never could.

The Industry’s Response

Once COD’s impact on conversion rates became visible, every e-commerce player in India adopted it. Amazon India launched with COD prominent in its offering. Snapdeal, Myntra, Jabong — the entire emerging e-commerce ecosystem built its logistics infrastructure around cash collection at the doorstep.

An entirely new category of last-mile logistics companies was born to serve this need. Blue Dart, Delhivery, Ecom Express, Shadowfax — companies whose core capability was not just moving packages, but handling cash reliably at scale across India’s diverse geography. This was not an incidental development. It was a direct consequence of one behavioural decision made by two founders in a Bengaluru apartment.

At its peak, COD accounted for over 60% of all e-commerce transactions in India — a figure that would have been unthinkable in any developed market, but made complete sense in the context of where Indian consumer trust actually stood.

The Compounding Effect

Flipkart’s growth following the introduction of COD was dramatic. The company expanded from books into electronics, fashion, and eventually every product category. By 2014, it was valued at over $1 billion — India’s first unicorn in the consumer internet space.

By 2018, Walmart acquired Flipkart for approximately $16 billion in what was, at the time, the largest e-commerce acquisition in history. The valuation was not just for Flipkart’s revenue or technology. It was for its position at the centre of a market it had fundamentally shaped.

The Indian e-commerce market that Flipkart helped create is today valued at over $70 billion, with projections to reach $300 billion by 2030. Much of that market exists because one company was willing to absorb buyer risk before buyer trust had been established.

The Lesson for Your Organisation

Sachin and Binny Bansal did not grow Indian e-commerce by making better products or running cleverer marketing.

They grew it by asking a question that most organisations never ask: whose fear is preventing this relationship from beginning? And then choosing to carry that fear themselves.

This question applies far beyond e-commerce. In every organisation, in every customer relationship, in every new behaviour you are trying to create, there is a moment of hesitation — a point at which someone is being asked to go first, to trust before trust has been earned.

The organisations that grow fastest are usually the ones willing to go first themselves. To absorb the initial risk. To demonstrate, through structural commitment rather than marketing language, that the customer’s experience is protected.

COD was not a feature. It was a values statement, made operational. And it compounded, over fifteen years, into an industry.
