Most first-year trade businesses that fail do not fail for lack of work. They fail because the owner was good with the tools and lost money on the business side: no deposit, quotes given out loud, prices that counted materials and labor and forgot everything else, invoices sent late, and extra work handed over for free. Add the one that finishes people off, running out of cash while you wait to get paid, and you have the short list of what actually kills new contractors. Every one of these is a business mistake, not a trade mistake. You can be the best carpenter in the county and still go under making all six. The good news is that none of them takes talent to fix. They take a couple of habits and the nerve to hold your line with a customer.
Being busy is not the same as making money
The dangerous thing about the first year is that it can feel like it is going great right up until the money runs out. Your phone is ringing, your calendar is full, you are working weekends. It looks like success. Then you add it up in the spring and there is nothing there, or worse, you owe tax on income that already went out the door in materials and gas.
That gap between busy and profitable is where new businesses die. The mistakes below are the specific leaks. Read them as a checklist of what to watch on every single job, because any one of them, repeated, is enough on its own.
Mistake 1: Taking no deposit, or the wrong one
If you order materials and start work before the customer has put any money down, you are financing their project with your own cash and betting they will pay. On a small job that is a bad night's sleep. On a big one it can end you. Order the cabinets for a kitchen, have the customer go quiet or cancel, and you are personally out thousands of dollars for materials you cannot return, with no signed deal to enforce.
A deposit fixes the incentive. The customer has skin in the game, and your material cost is covered before you commit to it. On smaller residential jobs a deposit of somewhere between a quarter and a half of the price is common practice, weighted higher on small jobs and lower on large ones.
The trap for new contractors is assuming you can take whatever deposit you like. Several states legally cap how large a residential deposit you can collect, and a few of those caps are much lower than the norm above. Take too much in one of those states and you have broken the law, even if the customer agreed. The deposit amount you can actually take, how to structure milestone payments around it, and which states cap what are all covered in Deposits and progress billing, and the specific limit where you work is in Working in Your State. Get that right before you ask for a dime.
Mistake 2: Quoting out loud instead of in writing
A price you said on someone's driveway is a price you cannot prove. When the customer decides later that you said something cheaper, or that the job included things it never did, a verbal quote gives you nothing to point to. Above a certain dollar amount a written contract is not just smart, it is legally required in some states.
Every quote goes in writing, even for a regular customer, even for your brother-in-law. A written quote does not need to be fancy. It needs the scope (what you will do and, just as important, what you will not do), the price or how it is calculated, a rough start and finish, the payment schedule, and a line that says any extra work needs a signed change order first. That last line is what saves you from Mistake 5.
What a real quote and contract need to contain, and the clauses that protect you versus the ones that get you sued, are covered in The contract that protects you. The rule here is narrow and absolute: nothing important stays verbal.
Mistake 3: Pricing off materials and labor only
The most expensive first-year mistake is quoting a job as materials plus your time and calling it a day. That price looks competitive because it is missing half your actual costs. It ignores everything it takes to be in business at all: the truck and its fuel, insurance, tools wearing out, your phone, your license and bond, bookkeeping, and the weeks of the year you do not bill because you are quoting, buying materials, sick, or slow.
Price a full year as if you bill fifty-two weeks and you have quietly given yourself a pay cut, because nobody bills fifty-two weeks. Price your labor at the hourly wage your old boss paid you and you have priced yourself as an employee, not a business, and forgotten that the business has costs the employee never saw.
The fix is to build overhead and profit into every price, on purpose, as line items you actually calculate rather than hope are in there somewhere. The full method, including how to figure your real hourly cost and the markup that leaves you a profit, is in How to price your work. If you take one thing from this guide to that one: the number that keeps you in business is not what the job costs you, it is what it costs you plus overhead plus profit.
Mistake 4: Invoicing late
Cash you have not billed for is cash you cannot spend, and the longer you wait to send an invoice, the longer you wait to get paid and the more likely the customer is to argue about what was agreed. "I'll send it next week when things calm down" is how a new contractor ends up floating three finished jobs and unable to buy materials for the next one.
Invoice the day you finish a job or a milestone, not when you get around to it. Make it easy to pay you, because friction is delay. On bigger jobs, bill in stages as you hit milestones instead of waiting for the end, so the customer's money and yours move together through the project. Set a clear due date, and add a late fee where your state allows one.
How to build an invoice that actually gets paid, the terms to put on it, and how to chase a slow payer without blowing up the relationship are covered in The invoice that gets paid. The discipline is simple and it is yours to keep: finished work gets invoiced the same day.
Mistake 5: Giving away extras
"While you're here, could you also..." is the most expensive sentence a customer can say to a new contractor, because the polite reflex is to just do it. Every bit of extra work you do without agreeing a price first is a gift you cannot afford to give. Do enough of them and you have worked a whole extra day across a job for nothing, on a price that already had no room in it.
The habit that fixes this is boring and it works: when the scope changes, you pause, you price the extra at your normal rate, and you get a yes in writing before you carry on. Not "mates' rates" because it is an add-on. Not a handshake. A quick text or email confirming what and how much is enough for small ones. In some states the change has to be in writing before you proceed or you cannot enforce it at all.
Change orders, including how to write them fast on site and how to get paid for the work you already did before things went sideways, are covered in Change orders. The mindset to carry: extra work is not a favor, it is more work, and more work has a price.
The one that finishes people off: running out of cash
The other five are leaks. This one is the flood. Most new trade businesses that go under do not run out of work, they run out of cash waiting for invoices to be paid. You can have a full calendar and a fat pile of unpaid invoices and still not make payroll or buy the next load of materials, because a job you have not been paid for does not spend.
Three habits keep you off the rocks:
- Do not start a job you cannot float. If you cannot cover the materials for thirty days out of your own pocket, you need a deposit structure that covers them (inside the legal caps) or a materials account at your supply house. Never let one job drain every dollar you have.
- Have a cushion before you jump. A common rule of thumb is three months of both business and personal expenses in the bank before you go full-time on your own. That buffer is what carries you through the gap between doing the work and getting paid for it.
- Get a line of credit while you still look bankable. Apply for a business line of credit early, while you have steady income or a job on record, not when you are already in trouble. Banks do not lend to a business that is visibly drowning.
Managing the feast-or-famine cash cycle month to month, once you are running, is covered in Managing cash flow in a feast-or-famine trade. And the tax version of this trap, spending money in the summer that the IRS is expecting in the spring, is why How much should I set aside for taxes exists. Set the tax money aside as it comes in and it is never a surprise.
Common questions
Why do contractors go out of business when they have plenty of work?
Because being busy and being paid are not the same thing, and most new trade businesses fail by running out of cash while they wait for invoices to clear, not by running out of work. A full calendar with a stack of unpaid invoices still cannot buy materials or cover your bills. The fixes are to never start a job you cannot float for thirty days, to keep a cash cushion of around three months of expenses before you go full-time, and to line up a business credit line while you still have steady income. Managing cash flow in a feast-or-famine trade covers the ongoing version.
How much deposit should I take on a residential job?
On smaller residential work a deposit of roughly a quarter to a half of the price is common, but several states legally cap how much you can collect, and some caps are far lower, so you must check your state before you ask. The deposit protects you from ordering materials the customer never pays for. Taking more than your state allows breaks the law even if the customer agrees to it. The exact limit where you work is in Working in Your State, and how to structure deposits and milestone payments is in Deposits and progress billing.
Is a text message enough for a change order?
For a small extra, a text or email that states the added work and the added price, with the customer's yes, is usually enough to protect you, and it beats doing the work on a handshake. For anything substantial, get it on a proper written change order, and be aware that some states require the change to be signed before you proceed or you cannot enforce it. The rule is the same either way: never do extra work without agreeing the price in writing first. Change orders covers how to do this fast on site.
What is the single biggest money mistake new contractors make?
Pricing a job as materials plus labor and forgetting overhead and profit, which produces a price that looks competitive but quietly loses money on every job. That number ignores the truck, insurance, tools, your phone, license and bond fees, and the weeks a year you do not bill. The fix is to build overhead and a real profit margin into every quote as figures you actually calculate. How to price your work walks through finding your true hourly cost and the markup that leaves you paid.
Should I lower my price to win my first few jobs?
No. Cutting your price to win early work trains you to lose money, attracts the customers who only care that you are cheap, and sets a rate you will struggle to climb back off. You end up busy, broke, and stuck. It is better to win fewer jobs at a fair price and build a base of customers who chose you for your work, not your discount. Your first jobs and your first 90 days covers how to land early work without wrecking your prices or your reputation.
The honest bit
- Nothing here is a state rule. Deposit caps, whether a written contract is legally required over a certain dollar amount, and whether a late fee is enforceable all vary by state. Get yours from Working in Your State before you rely on any of it.
- The dollar amounts used above are illustrations to make a scenario concrete, not a price list or a rate card. What to actually charge is a separate question covered in How to price your work.
- This is general guidance, not legal or tax advice. When a job, a contract, or an unpaid bill gets big enough to hurt, that is the point to get a construction attorney or a CPA on it, not to wing it.
