Buying a Business: The External View Before You Make an Offer

By Michael D. Rubin, CEO & Founder · Updated September 2026 · 726 words

Before making an offer, study the business from the outside the way a customer or a competitor would: how busy it is and when, who its customers are, how they are treated and what its reputation looks like. The financial statements tell you what happened. An outside view tells you how it happens, and it often confirms or contradicts the story in the marketing package.

One of the best-known acquisitions in American business began with a buyer sitting in his car for days, watching a small restaurant before he made an offer. The method still works, and it costs almost nothing.

What an outside view shows you

Write down what you see each time, with the date and hour. Patterns across several visits matter more than any single impression.

• Traffic and timing: how many customers come through, on which days and at which hours, and whether the quiet periods match what the seller described.
• Who the customers are: regulars or one-time visitors, businesses or households, local or from farther away.
• Service in practice: how quickly people are greeted, how phone calls are answered, and whether promised callbacks actually happen.
• Condition and upkeep: the state of the premises, the vehicles and whatever equipment the public can see.
• The competition: who else serves the same customers nearby, and how their prices and service compare.

Adapt the method to the kind of business

A shop, restaurant or service counter is easy to observe in person. Many companies that sell for millions are different: a manufacturer, a distributor or a home-services company does its work at customers' sites or behind a warehouse door. For those, the external view means something else. Look at the fleet on the road and how it is kept. Read online reviews over several years, not just the latest few, and note how the company answers complaints. Check its website, how easy it is to book work or request a quote, and how quickly anyone replies.

For trade businesses like those on our home services page, the way a crew behaves in a customer's driveway says a great deal about how the company is run. Suppliers and industry contacts also form views of a company over the years, though any conversation with them has to stay within your confidentiality obligations.

Try the business as a customer

Where it makes sense, become a customer. Buy the product, book the service or ask for a quote, or have someone you trust do it. Franchisors and larger companies use mystery shoppers for exactly this reason: it shows how a business treats people when the owner is not watching. Note how you were greeted, how long things took, whether the price matched the quote and whether anyone followed up.

Keep it proportionate. A few honest tests tell you what you need; repeated fake inquiries waste the company's time and, if noticed, damage your standing with the seller.

Stay inside the confidentiality agreement

Once you have signed a confidentiality agreement, you must not reveal that the business is for sale or approach its employees, customers or suppliers about it. Watching from the street, reading public reviews and using the business as an ordinary customer are generally fine. Asking staff whether the owner is selling, or telling a customer why you are curious, is not. Our answer on keeping a sale confidential explains why sellers guard this so closely. If you are unsure about a step, ask the seller's advisor first.

Bring what you learn into due diligence

The outside view is a starting point. If you saw quiet afternoons the seller described as busy, or a fleet in poorer shape than the equipment list suggests, raise it through the advisor and ask for the records that explain it. Due diligence, step eight of a professionally run sale, is where those questions get answered with documents. What you observed also helps you plan: it shows where service could improve and where the business may have room to grow once you own it.

Questions owners ask next

Is it acceptable to watch a business before buying it?

Observing a business from public places, reading its reviews and buying from it as an ordinary customer are normal parts of evaluating a purchase. What you must avoid is breaching a confidentiality agreement, trespassing or misrepresenting yourself to staff. If you are unsure about a specific step, check with your attorney or the seller's advisor first.

How many visits are enough?

Enough to see the pattern across different days and times, including the busiest and quietest periods the seller described. For a seasonal business, try to observe in more than one season or ask for records that show the difference. A handful of well-timed visits usually tells you more than many random ones.
