Why the barrier to starting has collapsed
An entrepreneur identifies a problem, builds something that solves it, and takes the risk of finding out whether anyone will pay. A digital entrepreneur does the same using digital tools — and those tools have removed almost every fixed cost that used to stand in the way.
Twenty years ago, starting a business meant premises, stock, and servers bought before the first customer appeared. Today a student can rent computing by the hour, reach customers through platforms that already exist, take payments through an existing gateway, and test whether anyone wants the product before building it properly. What is left is the hard part: knowing whether the problem is real.
- Cloud infrastructure — pay for computing by the hour rather than buying servers.
- Existing platforms — reach an audience through marketplaces and social media instead of building one.
- Payment gateways — accept money without becoming a bank.
- Open-source software — build on tools that cost nothing to license.
- Remote work — hire the person best suited to the job rather than the one who lives nearby.
Business models that work online
How a business makes money is a design decision, not an afterthought, and the syllabus names the common patterns. Each suits a different kind of product.
| Model | How it earns | Works when |
|---|---|---|
| E-commerce | selling goods online | you have a product and can deliver it |
| Subscription | a recurring fee for continued access | the value is ongoing, not one-off |
| Freemium | free basic tier, paid upgrade | the free version brings users who later need more |
| Advertising | selling attention to advertisers | you have a large audience and cheap content |
| Marketplace | commission on others' transactions | you can attract both buyers and sellers |
| SaaS | renting software over the internet | the software solves an ongoing business problem |
The freemium trap
Free users cost money to serve and most never upgrade — typical conversion is a few per cent. Freemium works only when serving a free user is nearly free and the paid tier offers something a serious user genuinely needs. A free tier that already does everything converts nobody, and a free tier that does nothing attracts nobody.
From idea to something you can test
The commonest way a first business fails is building the whole thing before discovering that nobody wanted it. The remedy is to make the cheapest possible version that tests the one assumption everything else depends on.
That version is the minimum viable product — the smallest thing that delivers real value to a real user and produces feedback. It is not an unfinished product; it is a deliberately narrow one.
A student wants to build an app connecting local tutors with students. Describe how to test the idea before writing any code.
- State the assumption everything rests on: that students cannot easily find a suitable tutor, and would pay for help doing so.Write it down explicitly. If this assumption is false, no amount of good code saves the business.
- Interview fifteen students and eight tutors about how they currently find each other, and what goes wrong.Ask what they did last time, not what they would do — people predict their own behaviour badly.
- Run the service manually: a form, a spreadsheet, and the student matching people by hand.This is a genuine MVP. It delivers the actual value and needs no app at all.
- Measure whether matches happen and whether anyone pays.Willingness to pay is the only evidence that counts. Enthusiasm is free.
- Only build the app once the manual version cannot keep up with demand.By then you know what to build, because you have done the job by hand and know where the work actually is.
Run the service by hand first; build software only when manual matching cannot keep up.
Digital marketing, and the skills that carry the business
Building the product is roughly half the work. Reaching the people it is for is the rest, and it is done differently online.
Search engine optimisation earns visitors by making pages genuinely answer what people search for. Social media reaches an audience where it already gathers. Content marketing attracts people by publishing something useful rather than an advertisement. Analytics tells you which of these is actually working, which is what separates marketing from guessing.
- Problem-solving — the business is a solution, so the skill is diagnosing the problem correctly.
- Communication — explaining the idea to customers, partners and anyone considering investing.
- Financial literacy — knowing the difference between revenue and profit, and how long the money lasts.
- Resilience — most first attempts fail, and the useful response is to learn what was wrong and try again.
- Digital literacy — being able to evaluate a tool rather than adopting whatever is fashionable.
Revenue is not profit
A business taking Rs 500 000 a month and spending Rs 600 000 is losing money, however impressive the first figure sounds. Profit = revenue − costs, and cash flow — whether there is money in the account this week — kills more young businesses than lack of profit does. A firm can be profitable on paper and still fail because customers pay in sixty days while wages are due on the first.
Before you leave this chapter
- Digital tools remove the fixed costs of starting; the hard part is knowing whether the problem is real.
- Know the models: e-commerce, subscription, freemium, advertising, marketplace, SaaS.
- An MVP is the smallest version that delivers real value and produces feedback.
- Willingness to pay is the only reliable evidence of demand.
- Profit = revenue − costs, and cash flow ends more businesses than losses do.
Why profitable businesses run out of money
The most common reason a young business closes is not that it was unprofitable. It is that money left the account before it arrived — wages and suppliers had to be paid this month, while customers pay in sixty days.
Profit is measured over a period; cash is what is in the account today. A business can be profitable every single month and still be unable to pay its staff, and no amount of future profit helps if the wages are due on Friday.
Set the delay to 0 and the two lines move together. Raise it and the profit line keeps climbing while the bank balance dives — the business is doing well and cannot pay its bills at the same time.
What a business actually does about it
Invoice immediately rather than at month end. Offer a small discount for early payment. Ask suppliers for longer terms so money leaves later. Keep a cash reserve covering several months of costs. And for a new business, take a deposit up front — the customer who will not pay a deposit is often the one who would not have paid at all.
