What owners say they would do differently

Most owners publish the climb and skip the falls. A handful in this database have said, on the record, what went wrong and what they changed, and their answers are more specific than the advice usually attached to boring businesses. Mike Andes has written about losing $75,000 on a gym venture and burning $100,000 in one winter keeping lawn crews busy on pointless work. Brian Scudamore fired his entire eleven-person team in the mid-nineties after admitting he had hired badly. This piece collects the mistakes owners name, grouped by type, with what each one did next.

Buying equipment before buying the location

The two vending owners in the database arrive at the same rule from opposite ends. Adam Hill says his hardest early lesson was equipment: machines are not interchangeable, and resellers still push obsolete stock onto beginners, especially machines that cannot take card readers. A cash-only machine quietly earns a fraction of what it could. His rule now is never to compromise on machine quality, then place it where the traffic already is.

Marcus Gram built his route from two machines and $10,000 of savings, and his $10,000 already included two card readers. His rule is about order rather than quality: never buy a machine until you have a place to put it. A well-placed machine grosses $800 to $1,300 a month by his account, and a badly placed one earns close to nothing. Put together, the two rules say that the location is the asset and the machine is the cost of serving it.

Getting the paperwork wrong

Cristobal Mondragon classified his cleaners as subcontractors early on when the state said they were employees. The penalties came to roughly $10,000, which was real money at the stage he made the mistake. What he did next is the useful part. Bumble Bee converted to properly employed, trained and certified staff, and that became the pitch: in a trade full of informal labor, the company that can show its people are legal and insured wins the customers who care most about who is inside their house. The business now reports $120,000 to $140,000 a month.

Doing the job you are bad at

Joshua Brown was running his own Google Ads for Brown's Pressure Washing and spending up to $10,000 a month. A hired professional cut that to about $3,000 with better results. It is the cheapest correction in this piece and probably the most common one available to any owner who has outgrown doing everything.

Scudamore's version cost more. By his account he had hired badly and built a culture he did not want, so he let all eleven people go and rebuilt around people he wanted to work with. He wrote a book called WTF (Willing to Fail). Alan Tursunbaev has the shortest form of the same lesson from mobile detailing: do not expect people to change, and if someone is unreliable, replace them rather than waiting.

Fighting the season instead of planning for it

Andes counts his $100,000 winter as a mistake because he kept crews busy rather than admitting the season was over. The lesson he draws is that the money is in systems that survive the founder's absence, not in heroics. Other owners in the database made the opposite choice on purpose. Kim Hatch keeps trained septic crews on payroll through winter months of about $30,000 so she is not short in $200,000 ones, and she treats that trough as the hard part of the job. Steve Hunsaker runs holiday lights in an eight-week season and lets the rest of the year cost almost nothing. The difference is that Hatch and Hunsaker decided in advance what the off-season was for. Our piece on seasonality as a feature goes through all three.

Buying a deal you cannot survive

The acquisition buyers are the most explicit about deal size. Nathan Lenahan bought Bart's Heating & Air for $400,000 against conventional advice to buy as large as you can finance, and his reasoning is that a $400,000 mistake is survivable while a $4 million one is not. Dan Burnside is the case that makes the argument for him: a $2.1 million HVAC company with roughly $800,000 of seller's discretionary earnings, seller fraud found after closing, a key employee who left to compete, and bankruptcy. His entry draws three warnings from it: diligence has to verify the seller and not just the numbers, the key employee is the asset, and small rural markets cut both ways.

Frank Rolfe says that when he paid $400,000 for his first mobile home park in 1996 he had no idea what he was doing. The park came with master-metered gas and electric, two of the worst problems a park owner can inherit. He kept going anyway, and by 2007 had bought and sold 24 parks. Dave Menz draws a related lesson from his $85,000 Craigslist laundromat: the deal you can afford is often a broken store, and the value is created in the renovation and the operating standard rather than in the purchase.

Waiting too long to hire

Kyle Landwehr did not choose the moment he stopped working the truck. He was doing $30,000 to $40,000 a month in junk removal when he broke his ankle stepping down from it, and in his telling that is what made him hire employees and build the company. He is also the owner who has published what the change cost: about 50 percent gross margin in year one, 30 to 35 percent with crews in year two, and about 20 percent after an operations manager at roughly $75,000 a year. The margin ledger shows the same steps across other trades.

What the list leaves out

Of the 33 owners documented here, about a dozen have entries that record anything specific about what they got wrong. The rest may have made the same mistakes and not mentioned them, so treat this as a sample of what owners are willing to say, not a full account. The common thread in what they did say is that most of the costly errors happened before the business was proven: equipment bought ahead of locations, workers classified the cheap way, a first deal bought blind.

The startup cost ladder shows how little most of these owners risked at the start, and Start here walks through the database for new readers. Full sourced entries for everyone named above are in the database. This site is one of SideRoad's weekly builds, and owners' corrections and second thoughts are added to their entries as they publish them.

Common questions

What mistakes do boring business owners say they made?

The ones documented here include buying vending machines that cannot take cards (Adam Hill), misclassifying cleaners as subcontractors for a roughly $10,000 fine (Cristobal Mondragon), running their own ads at up to $10,000 a month (Joshua Brown), hiring badly and firing a whole team (Brian Scudamore), and paying crews through a dead winter (Mike Andes).

How much did Mike Andes lose on his mistakes?

Andes has written about losing $75,000 on a gym venture and burning $100,000 in one winter keeping Augusta Lawn Care crews busy on pointless work rather than admitting the season was over.

How do acquisition buyers limit the cost of a mistake?

Nathan Lenahan bought deliberately small, paying $400,000 for an HVAC company, on the reasoning that a $400,000 mistake is survivable and a $4 million one is not. Dan Burnside's entry adds holdbacks or earnouts, so the seller carries some risk after closing.
