Ideas from Street Smarts, in plain words

Fifteen ideas from Norm Brodsky and Bo Burlingham's book Street Smarts, explained in everyday language, linked to the levels and sub-levels they matter to most, each with an Indian example in rupees and one thing to try.

About the book and the authors

Street Smarts: An All-Purpose Tool Kit for Entrepreneurs is by Norm Brodsky and Bo Burlingham, published by Portfolio, an imprint of Penguin. It first came out in 2008 under the title The Knack: How Street-Smart Entrepreneurs Learn to Handle Whatever Comes Up, and the Portfolio paperback was published as Street Smarts (the publisher’s page gives February 2010).

Brodsky built and sold several businesses in the United States, including a records-storage company, CitiStorage. For many years he wrote a monthly column for Inc. magazine, called “Street Smarts”, with Burlingham, an editor at large at Inc. who also co-wrote The Great Game of Business with Jack Stack. The book grew out of that column. It is written as practical advice from someone who learned by doing: what to watch in your numbers, how to sell and keep customers, how to negotiate, and how to become the boss of a growing company.

What this page is. Below are 15 of the book’s ideas, explained in our own words, not the book’s. For each one we say why it matters, which levels and sub-levels it matters to most, and work through a made-up Indian example. The book’s examples are American; the examples here are ours. We attribute an idea to the authors only where we could check it against Brodsky’s own Inc. columns or reliable summaries of the book (see sources at the end). For the full argument and the stories behind it, read the book.

Then go deeper with four articles that apply the most useful ideas to the ladder:

Money: cash, margin and survival

1. Cash comes first: make it before you spend it

The idea. Brodsky’s rule is that cash is hard to get and easy to spend, so a new business should earn money before it spends it. Money that goes on things that don’t bring in sales, such as a smart office, expensive furniture or a fancy logo, is money you won’t have when a bad month comes.

Why it matters. Profit is a calculation; cash is what pays the rent and the salaries. A business that runs out of cash stops, even if its accounts show a profit.

Where it applies most. Every level, but most of all the first rungs: a shopkeeper (1.2) or a new distributor (1.3), a sub-dealer (2.1), and product start-ups (4.2), where it is the same as watching burn rate and runway. See the stock and cash cycle and the article Cash before profit.

Hypothetical A new hardware shop

Sunil has ₹8,00,000 to start. He plans ₹5,00,000 of stock, ₹1,50,000 on fitting out the shop and ₹50,000 on signboards and branding. His monthly running costs (rent, two helpers, power) are ₹60,000.

  • Cash left after setting up: ₹8,00,000 − ₹5,00,000 − ₹1,50,000 − ₹50,000 = ₹1,00,000
  • Months of running costs that covers: ₹1,00,000 ÷ ₹60,000 = 1.67 months
  • If he spends ₹75,000 on the fit-out and ₹10,000 on a simple board: ₹8,00,000 − ₹5,00,000 − ₹75,000 − ₹10,000 = ₹2,15,000 left
  • That covers ₹2,15,000 ÷ ₹60,000 = 3.58 months while the shop finds its customers.

Try this: list every planned spend that will not directly bring in a sale in the next three months, and cut or delay half of it.

2. Gross margin, not sales, is the number that matters

The idea. Brodsky treats gross margin as the key number. Gross profit is sales minus the cost of the goods you sold; gross margin is that gross profit as a percentage of sales. Gross profit is what pays your overheads (rent, salaries, interest). Turnover on its own tells you very little.

Why it matters. The lower your margin, the more you must sell to pay the same overheads. His column makes the point with a simple ratio: at a 10% gross margin you need 10 of sales for every 1 of overhead; at 40%, just 2.50.

Where it applies most. Traders, where margins can be thin: wholesalers and distributors (1.3) and super stockists (1.4). And manufacturers deciding between job work (3.1), commodity products (3.4) and their own brand (3.5). See margins and markups, break-even and the article Gross margin, not turnover.

Hypothetical Same overheads, different margins

A shop sells ₹1,00,000 of goods that cost it ₹75,000.

  • Gross profit: ₹1,00,000 − ₹75,000 = ₹25,000
  • Gross margin: ₹25,000 ÷ ₹1,00,000 × 100 = 25%

Its overheads are ₹60,000 a month. Sales needed each month just to cover them:

  • At a 25% gross margin: ₹60,000 ÷ 25% = ₹2,40,000
  • At a 10% gross margin: ₹60,000 ÷ 10% = ₹6,00,000
  • Per ₹1 of overhead: ₹1 ÷ 10% = ₹10 of sales at 10%, and ₹1 ÷ 40% = ₹2.50 at 40%.

Try this: work out last month's gross margin, then divide your monthly overheads by it. That is the sales you need every month before you make a rupee.

3. First, survive until the business pays its own bills

The idea. The book says the first goal of a new business is simply to survive long enough to become viable: to pay its own bills out of the money it brings in, without fresh money from you or a lender. Until then, the only opportunity worth chasing is building a base of customers that gets you there.

Why it matters. Most new businesses lose money for a while. The question is whether your money lasts longer than that while. Keeping some money in reserve matters too: the book notes that putting in more capital after you thought you had put in your maximum is hard.

Where it applies most. Anyone starting out, at any level, and especially product start-ups (4.2) and companies doing their own R&D (4.3), whose wait is longest. See investment math for runway and break-even.

Hypothetical How long can you wait?

After setting up, a small packaged-snacks start-up has ₹3,00,000 left. For now, its gross profit falls short of its monthly expenses by ₹50,000.

  • Months before the money runs out: ₹3,00,000 ÷ ₹50,000 = 6 months
  • If it cuts the monthly shortfall to ₹30,000: ₹3,00,000 ÷ ₹30,000 = 10 months

It becomes viable when monthly gross profit covers monthly expenses. With expenses of ₹1,20,000 a month and a 30% gross margin, that needs ₹1,20,000 ÷ 30% = ₹4,00,000 of sales a month.

Try this: write down the monthly sales at which your business would pay its own bills, and the month your money runs out if you don't get there. Check both every month.

4. A sale is not finished until you collect

The idea. In Brodsky’s view a sale is not complete until the money is in your bank. Giving customers credit means lending them money, so treat your dues (receivables) like a lender treats a loan book: check whether a customer is good for the credit before you give it, learn how long each customer really takes to pay, and watch your average collection time and how old your dues are (current, over 30, 60, 90 days and so on).

Why it matters. Every rupee owed to you is a rupee you have lent out, often without interest. When customers pay more slowly, your money gets stuck even while sales and profit look fine.

Where it applies most. Wholesalers and distributors (1.3), super stockists and C&F agents (1.4), dealers who sell to institutions or fleets, and component suppliers (3.3) who wait for big customers to pay. See turnover and credit cycles, the cash cycle and interest.

Hypothetical How much have you lent your customers?

A distributor sells ₹9,00,000 a month, all on credit, and customers take 45 days on average to pay. Treating a month as 30 days:

  • Owed to the distributor at any time: ₹9,00,000 ÷ 30 × 45 = ₹13,50,000
  • If the average falls to 30 days: ₹9,00,000 ÷ 30 × 30 = ₹9,00,000
  • Money freed: ₹13,50,000 − ₹9,00,000 = ₹4,50,000
  • If that money had been borrowed at 12% a year, the yearly interest saved: ₹4,50,000 × 12% = ₹54,000

Try this: list everyone who owes you money, with how many days each bill is overdue. Call the oldest three this week.

5. Know your numbers, and track them by hand

The idea. Brodsky advises that in the first year or two of a new business you write down your monthly sales and gross margin by hand, broken down by product and by customer. Writing the numbers yourself gives you a feel for them that a software report doesn’t.

Why it matters. Totals hide things. One product line or one customer can be carrying the business while another quietly eats your margin. You will only spot it if you look at the parts.

Where it applies most. Any business with many products or customers: shopkeepers (1.2), distributors (1.3), 3S dealers (2.3) with sales, service and spares, and product start-ups (4.2) learning which products and customers are worth it. See margins and unit economics.

Hypothetical Two product lines in one shop

A hardware shop’s month, by product line:

  • Paint: sales ₹4,00,000, cost ₹3,40,000. Gross profit ₹4,00,000 − ₹3,40,000 = ₹60,000; margin ₹60,000 ÷ ₹4,00,000 × 100 = 15%
  • Plumbing: sales ₹2,00,000, cost ₹1,40,000. Gross profit ₹2,00,000 − ₹1,40,000 = ₹60,000; margin ₹60,000 ÷ ₹2,00,000 × 100 = 30%

Plumbing earns the same gross profit from half the sales. The shop’s total sales alone would never show that.

Try this: on one sheet of paper, write last month's sales and gross profit for your top five products and top five customers.

6. Find the one number you can watch every week

The idea. Brodsky wrote that every business has a “magic number”: one figure you can check daily or weekly that tells you early how the business is doing, long before the monthly accounts arrive. In his records-storage business it was the number of new boxes coming in each week. Yours will be different; the book has a chapter on such key numbers.

Why it matters. Monthly accounts tell you what already happened. A weekly number that moves before sales do gives you time to act: to slow hiring, chase customers or cut an order.

Where it applies most. 3S dealers (2.3) (job cards opened, enquiries, test rides), multi-outlet groups (2.4), and product start-ups (4.2) (orders or sign-ups per week). See service and warranty math.

Hypothetical A workshop’s weekly number

A two-wheeler dealer’s workshop usually opens about 120 job cards a week. One week it opens 90.

  • Fall in job cards: (120 − 90) ÷ 120 × 100 = 25%
  • With an average bill of ₹1,500 per job card, billing that week is down by 30 × ₹1,500 = ₹45,000

Seeing this in week one, not at the month’s end, gives the dealer three extra weeks to find out why (a new workshop nearby? service reminders not going out?).

Try this: pick one number you can count every week that usually moves before your sales do. Write it on a wall chart for the next 12 weeks.

7. Be wary of big, low-margin sales on credit before you are viable

The idea. In his column on following the numbers, Brodsky warns new businesses against chasing large, low-margin, one-off sales on credit. If that one customer doesn’t pay, the loss can wipe out your starting capital. Small sales at a good margin are safer while you are building up. Once the business is viable, some big low-margin sales can make sense, as long as you check the customer’s credit and a non-payment would not sink you.

Why it matters. The bigger the sale and the thinner the margin, the more you lose if you are not paid, and the longer it takes to earn the loss back.

Where it applies most. New distributors (1.3) and trading houses (1.5) offered a big order, and job workers (3.1) offered one large contract. See break-even.

Hypothetical One big order or a small good one?

  • Order A: ₹50,000 at a 30% gross margin earns ₹50,000 × 30% = ₹15,000 of gross profit
  • Order B: ₹5,00,000 at a 10% gross margin earns ₹5,00,000 × 10% = ₹50,000
  • If Order B’s buyer never pays, you have lost the cost of the goods: ₹5,00,000 − ₹50,000 = ₹4,50,000
  • To earn that back at a 30% margin you would need ₹4,50,000 ÷ 30% = ₹15,00,000 of new sales.

Try this: before taking a large credit order, ask: if this customer never pays, how many months of my profit is that? If the answer frightens you, ask for an advance or a smaller first order.

8. Check whether you can pay what falls due soon

The idea. Brodsky points out that when what you owe in the short term is more than what you will soon turn into cash, a business is in serious danger, whatever its profit. He suggests watching the current ratio: current assets (cash, stock, dues from customers) divided by current liabilities (suppliers, short-term loans and other bills due within a year). In his column he treats about 1.25 or more as reasonably healthy and below 1 as trouble; that is his rule of thumb, and a lender may use different ones.

Why it matters. A business can be profitable and still be unable to pay its suppliers next month. A common cause is paying for long-term things (a machine, a showroom) with short-term money.

Where it applies most. Every level with stock and credit: distributors (1.3), authorised dealers (2.2) carrying stock on channel finance, and manufacturers buying machines.

Hypothetical A distributor’s current ratio

  • Current assets: cash ₹2,00,000 + stock ₹6,00,000 + dues from customers ₹4,50,000 = ₹12,50,000
  • Current liabilities: owed to suppliers ₹7,00,000 + short-term loan ₹3,00,000 = ₹10,00,000
  • Current ratio: ₹12,50,000 ÷ ₹10,00,000 = 1.25

Now the distributor takes another ₹4,00,000 short-term loan and spends it on a delivery vehicle. The vehicle is not a current asset, so current assets stay at ₹12,50,000:

  • Current liabilities: ₹10,00,000 + ₹4,00,000 = ₹14,00,000
  • Current ratio: ₹12,50,000 ÷ ₹14,00,000 = 0.89

Try this: from your last balance sheet, add up current assets and current liabilities and divide. If it is below 1, talk to your accountant before you take on anything new.

Customers, selling and negotiating

9. Don’t let one customer become your whole business

The idea. The book suggests a start-up focus first on smaller customers at good margins, because losing one won’t finish you. In a later Inc. column Brodsky warns about the opposite trap: a company whose customers mostly share one thing (the same owner, or the same industry) can lose a huge amount of business at once, and is worth less when it is time to sell. His answer: keep serving the big customer, but put salespeople on winning customers elsewhere.

Why it matters. A big customer can ask for a price cut, pay later, move orders to a rival or simply cut its own budget. The more of your sales it makes up, the less you can say no.

Where it applies most. Job workers (3.1), contract manufacturers (3.2) and component suppliers (3.3) selling to one OEM (the brand); also distributors with one principal. See OEM vs commodity, OEM pricing and the article One big customer.

Hypothetical A component maker’s biggest customer

A component maker sells ₹3,00,00,000 a year; one OEM buys ₹1,80,00,000 of it.

  • That customer’s share: ₹1,80,00,000 ÷ ₹3,00,00,000 × 100 = 60%
  • If the OEM moves half its orders to another supplier, sales lost: ₹1,80,00,000 × 50% = ₹90,00,000
  • At a 20% gross margin, gross profit lost: ₹90,00,000 × 20% = ₹18,00,000 a year, while rent, salaries and loan payments stay the same.

Try this: work out what share of last year's sales came from your biggest customer and your biggest three. Set a date by which you want both shares lower.

10. In a negotiation, find out what the other side wants first

The idea. Brodsky’s columns on negotiating say the most common mistake is thinking only about what you want. Spend your effort learning what the other side wants, and how badly, before you show your own hand. The book’s chapter on deals adds two points: settling a smaller issue first can give you bargaining power on the one that matters most, and it’s fine to walk away from a dispute a little unhappy rather than let emotion decide.

Why it matters. Price is often not the other side’s main concern. If you know what is (faster payment, a steady order, a quick decision), you can give them that and get a better deal on what matters to you.

Where it applies most. Buying from suppliers at every level, dealers (2.2) negotiating with brands, and technology licensees (4.1) negotiating licence terms. See interest to price the payment terms you trade.

Hypothetical Trading faster payment for a better price

A trader buys ₹10,00,000 of stock a month on 45 days’ credit. By asking questions, he learns the supplier’s bank limit is stretched: getting paid faster matters more to the supplier than price. He offers to pay in 15 days in return for 2% off.

  • Saving each month: ₹10,00,000 × 2% = ₹20,000
  • Cost of paying 30 days earlier, if he borrows at 12% a year: ₹10,00,000 × 12% × 30 ÷ 365 = ₹9,863
  • Gain each month: ₹20,000 − ₹9,863 = ₹10,137

Try this: before your next negotiation, write down three things the other side might want besides price, and ask questions to find out which matters most.

11. Sell what the customer values, and don’t discount spare capacity

The idea. The book says to listen to customers and sell them solutions to what they care about, not what you happen to like about your product. It also warns against filling spare capacity by selling it cheap: your regular customers will not happily keep paying more for the same thing. Discount for real reasons, such as volume or better terms, or keep the price and add value.

Why it matters. A discount to fill idle machines or empty space is never really a one-off. Once regular customers hear of it, you may have to give it to them too.

Where it applies most. Any business with fixed capacity: job workers (3.1) and contract manufacturers (3.2) with idle machine hours, 3S dealers (2.3) with empty service bays, and storage or logistics services. See capacity and the machine hour rate.

Hypothetical Filling idle machine hours

A job worker sells 1,000 machine hours a month to regular customers at ₹600 an hour, and has 200 hours idle. A new customer offers ₹420 an hour for the idle time.

  • Extra income from the idle hours: 200 × ₹420 = ₹84,000 a month
  • If regular customers hear of it and insist on the same rate: 1,000 × (₹600 − ₹420) = ₹1,80,000 a month lost

The risk is more than twice the gain.

Try this: before quoting a lower price, write down the reason (more volume, advance payment, a longer contract) that you could explain to a regular customer.

12. Pay salespeople so they sell as a team

The idea. The book argues that salespeople paid on commission tend to treat customers as their own, not the company’s, and to guard their accounts. Brodsky prefers to pay salary plus a bonus tied to how the company and the person do, so salespeople help each other. Because it is hard to hire good salespeople on salary alone, the book suggests starting a new hire on commission and buying the commission out later.

Why it matters. If one salesperson “owns” your biggest customers, those customers can leave when the salesperson does.

Where it applies most. Distributors (1.3), authorised dealers (2.2) and multi-outlet groups (2.4) with sales teams, and manufacturers with field sales. See targets and schemes.

Hypothetical From commission to salary plus bonus

A distributor hires a salesperson on 3% commission. In month six they sell ₹12,00,000:

  • Commission: ₹12,00,000 × 3% = ₹36,000

After a year, the distributor moves them to a salary of ₹30,000 plus a bonus of up to ₹10,000 a month, paid half on the company’s results and half on their own:

  • Most they can earn in a month: ₹30,000 + ₹10,000 = ₹40,000
  • Each half of the bonus: ₹10,000 ÷ 2 = ₹5,000

Try this: list your top ten customers and who in your business they would call first. If it is the same one person for most of them, introduce a second contact.

People and the long run

13. Culture is the boss’s job, and you can’t hand it off

The idea. Brodsky says culture drives a company, and defining and keeping it up is one job the owner cannot delegate. The book adds that there should be only one culture in the company, not a different one under each manager, and that a strong culture attracts better job applicants. It also notes that cutting creeping expenses needs everyone’s help, which only happens when people care about the company.

Why it matters. As a business grows, you stop seeing every customer and every bill. How people behave when you are not there decides how customers are treated and how money is spent.

Where it applies most. Once you employ more than a handful of people: multi-outlet dealer groups (2.4), contract manufacturers (3.2), own-brand manufacturers (3.5) and growing product companies (4.3).

Hypothetical Small savings, noticed by staff

Staff who care point out two creeping costs:

  • Courier charges cut from ₹18,000 to ₹12,000 a month: (₹18,000 − ₹12,000) × 12 = ₹72,000 a year
  • Packing waste cut from ₹25,000 to ₹20,000 a month: (₹25,000 − ₹20,000) × 12 = ₹60,000 a year
  • Total saved: ₹72,000 + ₹60,000 = ₹1,32,000 a year
  • At a 20% gross margin, earning that much extra would take ₹1,32,000 ÷ 20% = ₹6,60,000 of extra sales.

Try this: write down, in three sentences, how you want customers treated and money spent. Read it out at your next staff meeting and ask for one example of each from the past month.

14. Run it as if you’ll keep it forever, and build it so someone would buy it

The idea. Brodsky’s advice is to skip shortcuts and run the business as if it will last forever, even if you plan to sell; he says that is what made his own company worth more. In another column he argues for building a business so that it could be sold, even if you never intend to. The book adds that buyers pay for future earning power, so they pay less when that future looks risky, and that a business with weak margins is hard to sell.

Why it matters. The same things that make a business attractive to a buyer (steady margins, many customers, good records, a team that runs without the owner) also make it safer and easier to own.

Where it applies most. Higher rungs where a sale or a partner is realistic: multi-outlet groups (2.4), master franchisees (2.5), own-brand manufacturers (3.5) and product companies (4.3). See ROI and payback and the article Build a business someone would buy.

Hypothetical Same profit, different price

Two businesses each make ₹25,00,000 of profit a year. Suppose (the multiples are made up for illustration) a buyer would pay four years’ profit for one with many customers, steady margins and a team that runs it, but only two and a half years’ profit for one that depends on one customer and on the owner.

  • First business: 4 × ₹25,00,000 = ₹1,00,00,000
  • Second business: 2.5 × ₹25,00,000 = ₹62,50,000
  • Difference: ₹1,00,00,000 − ₹62,50,000 = ₹37,50,000

Try this: imagine a buyer visits next month. Write down the three things about your business that would worry them most, and fix one this quarter.

15. Your life plan comes before your business plan

The idea. Brodsky puts the life plan first: decide what you want from life, then build the business that serves it. The book says your personal goals, such as where you want to be in five years and what you want to earn, should help decide how fast to grow.

Why it matters. Growth takes money, time and risk. Without a personal goal, there is no way to tell whether a bigger business is worth what it costs you.

Where it applies most. Choosing your level in the first place (try the self-evaluation), and deciding when to climb to the next sub-level. It matters most at new products and services, where the time and risk are largest.

Hypothetical Turning a personal goal into a sales target

An owner wants to take home ₹1,50,000 a month.

  • Per year: ₹1,50,000 × 12 = ₹18,00,000
  • With other overheads of ₹40,00,000 a year and a 20% gross margin, yearly sales needed: (₹18,00,000 + ₹40,00,000) ÷ 20% = ₹2,90,00,000

Try this: write what you want your life to look like in five years: income, time with family, where you live. Then work out the business size that delivers it, no bigger.
