Most business plan templates were written for someone applying for funding. If you buy stock and sell it at a market, online or from a small shop, you do not need thirty pages of mission statement. You need one page that tells you whether the thing makes money and whether you can survive the gap between paying for stock and getting paid.

The plan below has eight sections. It fits on one page, takes an afternoon, and every section exists because getting it wrong is a common way traders lose money. There is a fill-in structure to copy and a worked example in rand.

One thing to fix in your head first: what usually decides whether a trading business survives is not margin, it is cash cycle. Good margins and a slow cycle still run you out of money.

The eight sections of a one-page plan

Section 1: What you sell and to whom

Write two sentences: one naming the product range narrowly, one naming the customer specifically enough that you could point at one.

“Homeware” is not a range, it is a department. “Kitchen storage containers and dish racks” is a range. “Everyone” is not a customer. “Women aged 25 to 50 restocking a household, buying at my Saturday market and on WhatsApp” is. Narrowness is the point: a narrow range means you buy deeper, get better prices and become known for something, while a trader who sells a bit of everything is remembered by nobody.

Section 2: Where you buy

Name your supplier or supply area, your buying frequency, and the minimum spend that gets a decent price. Then answer three questions:

• What does a carton cost, and how many units are in it? The per-unit price at carton quantity is your real cost.
• What does the trip cost? Taxi, petrol, bakkie hire, parking. Divide by units bought.
• What is your backup? Traders with one source stop trading when that source does.

Our guide on buying wholesale, minimums and trade prices covers how to ask about carton pricing.

Section 3: Unit economics

The heart of the plan. For your three main products, work out landed cost, selling price and gross profit per unit. Landed cost is purchase price plus transport per unit, packaging, payment fees and a breakage allowance, not the price on the slip. Our guide on pricing products for resale has the full worksheet.

Section 4: Fixed monthly costs

Fixed costs are what you pay whether you sell anything or not. Traders forget half of them, which is why their break-even is wrong.

• Stall or shop rent, or pitch fees
• Transport you pay regardless of volume
• Airtime and data
• Bank charges and card machine rental
• Storage, wages, and anything you pay a bookkeeper
• Packaging bought in bulk

Our guide on the business bank account for a small trader explains how to price this line.

Section 5: Break-even in units

Break-even units equals fixed monthly costs divided by average gross profit per unit. It answers the question that matters at the start: how much must I sell before I have earned anything?

Do it in units, not rand. “R14,000 turnover” means nothing at a stall; “eleven items a day” means something. If the number is higher than you can realistically sell, the plan is wrong now, while it is free to change.

Section 6: Cash cycle

Your cash cycle is the days between money leaving your hand for stock and coming back from the customer: days stock sits, plus days customers take to pay, minus any supplier credit.

A trader buying cash and selling the same week needs very little working capital. One who buys a month of stock upfront and lets customers pay later has a long cycle, and a long cycle eats cash even in a good month. More in our guide on cash flow, stock, float and slow weeks.

Section 7: Risks

Three risks, each with one sentence on what you would do. Just the three most likely: the supplier runs out of your best seller, rain wipes out a market day, load shedding kills your card machine, stock is stolen, or January arrives and nobody has money.

Section 8: Month one

Five actions, each dated and small enough to finish. “Grow the business” is not an action. “Buy two cartons of storage containers on the 3rd” is.

The fill-in template

Copy this into a notebook or a phone note and complete every line. Do not skip one because you are unsure; write a best guess and mark it to confirm later.

A worked example

Below is a completed plan for an imaginary trader. Every figure is illustrative and made up for this example. They are not quoted prices and prices move, so use them to see the shape of the sums, then put in your own numbers.

Thandi’s kitchen storage stall (illustrative)

What she sells: Kitchen storage containers, dish racks and cutlery holders, to women restocking a household, at a Saturday market plus WhatsApp orders. Where she buys: Wholesale shops in Durban, every three weeks, roughly R4,000 a trip, with a second supplier identified.

Unit economics (illustrative figures)

Landed cost adds transport across the units bought, a bag, a breakage allowance and card fees.

Fixed monthly costs (illustrative figures)

Break-even

R3,150 divided by R70 average gross profit is 45 units a month, or about 8 per market Saturday once weekday WhatsApp orders are counted. Thandi has sold 15 to 25 on a good Saturday, so the plan works, and she now knows a rained-out Saturday costs most of a week’s profit.

Cash cycle

Stock sits about 21 days. Market customers pay immediately and WhatsApp customers within about 3 days, so call it 2 on average, and her supplier gives no credit. Her cash cycle is roughly 23 days.

So she always has three weeks of stock money on a shelf rather than in her pocket. With a R4,000 trip every three weeks, roughly R4,000 to R5,000 of working capital is permanently tied up, plus a change float. Draw that out in a quiet month and she cannot buy the next trip, so the business stops even though it was profitable.

Risks and month one

• Rain on a market day. Push a WhatsApp special and offer delivery.
• Best seller out of stock. Use the second supplier and accept a lower margin rather than an empty table.
• Spending the stock money. Separate business account, and pay herself R2,000 on the 25th, no more.

1. Open a business bank account by the 5th.
2. Confirm carton prices and minimums with both suppliers by the 8th.
3. Photograph all three products for WhatsApp by the 10th.
4. Trade four Saturdays and write down every sale.
5. On the 30th, redo this page with the real numbers.

Why traders fail on cash cycle, not margin

Ask a struggling trader what went wrong and they usually blame thin margins or a competitor undercutting them. Far more often the margin was fine and the money was not there on the day it was needed.

Profit is earned when you sell. Cash leaves when you buy. If those events are three weeks apart, every rand of growth widens the gap, because a bigger business needs more stock on the shelf. Growth consumes cash, so a trader who doubles sales without doubling working capital hits a wall just when things are going well.

Three things stretch the cycle badly, and all are avoidable:

1. Buying too deep on slow lines. Ten cartons of something that sells twice a month is cash locked in a box.
2. Letting customers pay later. Every day of credit you extend is a day you fund. If you must give terms, give them to few customers, with a limit.
3. Taking money out on good weeks. A strong week is often just the stock money coming back. Pay yourself a fixed amount on a fixed day.

Two defences work. Keep a stock float you never dip into, sized at about one buying trip, and measure your cash cycle monthly so you see it lengthening before it hurts.

When you need more than one page

A one-page plan is enough for a stall, a WhatsApp business or a small shop. You need a fuller document when someone else’s money or name is involved: finance, a partner, a long lease, a contract bid. Even then, write the one-pager first, because a long plan built on unexamined unit economics is a tidy way of being wrong. If you are registering formally, see our guide on registering a business step by step.

Frequently asked questions

How do I write a simple business plan for a small trading business?

Cover eight things on one page: what you sell and to whom, where you buy, your unit economics, your fixed monthly costs, your break-even in units, your cash cycle, your three main risks, and five dated actions for month one.

How do I calculate break-even for a trading business?

Divide your fixed monthly costs by your average gross profit per unit. If fixed costs are R3,150 and you make R70 gross profit per unit, you break even at 45 units a month. Work in units, because units are something you can picture selling.

What is a cash cycle and why does it matter?

Your cash cycle is the days between paying for stock and being paid by customers: days stock sits, plus days customers take to pay, minus any supplier credit. It matters because a long cycle drains cash even in profitable months, and growth makes it worse by needing more stock on the shelf.

Why do small traders fail if their margins are good?

Usually cash timing rather than pricing. Profit is earned when stock sells, but cash leaves when stock is bought, and the gap has to be funded. Buying too deep, giving credit and drawing money out after a good week all stretch that gap until the next buying trip cannot happen.

Do I need a business plan to start selling?

Not a formal one, but you do need the numbers. Working out landed cost, fixed costs, break-even units and cash cycle before you buy stock takes an afternoon and prevents the commonest early mistakes. A full written plan is for finance applications, a partner or a long lease.

How much working capital does a small trading business need?

Enough to cover unsold stock plus a float, usually about one full buying trip’s worth at any time. If you spend R4,000 every three weeks and stock takes three weeks to sell, expect roughly that much to be permanently tied up. Treat it as the business’s money, not yours.
