How to test a business idea in 14 days for under ₹10,000

The costly mistake in starting a business is almost never picking the wrong idea. It is committing capital to an untested one — the deposit, the interiors, the first inventory lot — and only then discovering the thing a fortnight of asking would have told you.

A test is not market research. Research tells you the market exists. A test tells you whether this market will pay you. Here is a version that fits into 14 days and under ₹10,000.

Day 0: write the sentence that can be wrong

Before anything else, write your idea as one falsifiable claim, with a number in it:

"At least 15 out of 50 [specific people] in [specific area] will pay ₹[price] for [specific thing] within two weeks."

If your version of that sentence has no number, or no named group of people, or the thing being sold could mean three different offerings, you cannot test it yet. Rewrite until it is small enough to be wrong.

The point of the number is that it makes the test end. Without it, every result reads as encouraging.

Days 1 to 3: find out what already exists

Cheap, and it kills more ideas than anything else on this list:

• Visit or call five existing providers, as a customer. Note the actual price, not the listed one; the wait time; and what they are bad at.
• Search the way your customer would search, in the language your customer uses. If nothing comes up, that is either an opening or a sign nobody is looking.
• Find one person who tried this and stopped. They will tell you more in 20 minutes than any report.

If, at the end of three days, your only differentiator is that you will be cheaper, stop and rewrite the claim. Being cheaper is not a position a new business can hold.

Days 4 to 8: ask for money, not opinions

This is the part people skip, and it is the entire test. Opinions are free, so they are worth what they cost. Signals worth counting, in ascending order of value:

1. An advance, however small.
2. A written commitment to a specific date and price.
3. A phone number given unprompted for a follow-up.

And things that are not signals: likes, "definitely, bhai", a WhatsApp group joining, and your family's enthusiasm.

Ways to ask that cost almost nothing: a single-page offer sent to 50 targeted people, a stall for one weekend, a pre-order form, one day of doing the service manually for two paying customers. Ten thousand rupees is enough for one of these done properly. It is not enough for all four done badly.

Days 9 to 11: put the money model on one page

Four lines, for one unit of whatever you sell:

• Price per unit
• Direct cost per unit
• Contribution per unit (the first minus the second)
• Fixed monthly costs — rent, salary, your own drawings, EMI

Then divide: fixed costs ÷ contribution per unit = units per month to break even. Now compare that number to the demand you actually observed in days 4 to 8.

This single division is where most ideas fail, and they fail quantitatively rather than as a matter of taste. Needing 400 covers a month in a location that sees 200 walk-ins is not a marketing problem to be solved later. It is arithmetic.

Do it in the pessimistic case too: 30% lower price, 20% higher input cost. If the idea only works in the optimistic case, you have found the answer.

Days 12 to 14: decide, and write down why

Three permitted outcomes, and "keep thinking about it" is not one of them:

• Go. The claim held, the arithmetic works at observed demand. Commit the smallest amount of capital that gets you to real revenue — rented before bought, shared before owned, manual before automated.
• Rewrite. The demand was real but the offer, price or customer was wrong. You have learned something specific; write the new claim and run a shorter test.
• Stop. The claim failed. This is a successful test. You spent ₹10,000 and a fortnight instead of ₹5 lakh and a year.

Write the reason down either way. In six months you will not remember whether you stopped because of the numbers or because of a bad Tuesday.

A test you cannot fail is not a test. It is a plan you have already made, wearing the costume of a decision.
