"What is working capital? (and why stock eats your cash)"

A common surprise for new sellers is having a busy month and an empty bank account at the same time. Orders are coming in, the store looks alive, and yet you cannot afford to restock. The reason is usually working capital, and it is worth understanding before it catches you.

What it means

Working capital is the money you need to keep the business running between paying for things and getting paid for them. For a product seller, it is largely the cash you spend on stock, packaging and other costs before customers pay you, minus the time it takes for that money to return.

You do not need to calculate it precisely to benefit from the idea. The picture is more important than the formula. For a simple formula version, see working capital, a simple formula for sellers.

Rs 50,000 on stock, before a single sale

Suppose Sunita starts a candle brand. She spends Rs 50,000 in the first month on wax, jars, wicks, fragrance and boxes, and makes a first batch of candles. At this point she has sold nothing. Her bank balance has fallen by Rs 50,000, and the money is now sitting on a shelf as candles.

Now follow the cash.

• Week one, photos and listing. No sales, cash is still out.
• Weeks two to four, some orders. Suppose she sells candles that cost her Rs 15,000 to make. Even then, the cash does not all arrive at once.
• Prepaid orders may take a few days to settle into her bank.
• COD orders arrive later, after delivery and after the courier remits the money. What COD remittance means for your cash flow explains the gap.
• Some parcels come back as returns, and that money does not arrive at all.

So after a month she might have sold stock that cost Rs 15,000, but only part of that has reached her account, and Rs 35,000 of the original spend is still sitting as unsold candles. If a supplier now asks her to pay for the next batch, she may not have the cash even though she is technically making a profit on paper.

Why growth makes it worse

A growing store needs more stock before it sells more. Every extra reorder increases the amount of cash tied up. A seller who doubles their order volume often has to double their stock spend first. This is why a brand can be profitable and still run out of cash.

Ways to be gentler on your cash

• Buy stock in smaller batches while demand is uncertain. Bulk boxes vs small batches, cash maths shows the trade-off.
• Keep a small catalogue until you know what sells. The case for a smaller catalogue is relevant.
• Take part payment or full prepayment on custom and slow orders where it suits you.
• Clear slow stock before it freezes more money. See slow stock clearance breakeven.
• Keep a cash buffer for restocking, separate from owner pay.

Starting working capital for a new store helps you size that buffer before launch.

A question to ask every week

How much cash do I have, how much is sitting as stock, and how much is on its way to me? Writing three numbers on a page, each week, is enough to avoid most nasty surprises.

Working capital is not a loan or a product. It is simply a way of looking at where your money is at any moment. Once you watch it, you stop confusing profit with cash, and you make calmer decisions about when to restock and how much.
