The Short Answer

What Is a Job Size Limit?

Textbook Definition

A job size limit is a written ceiling on the contract value of any single job, set so that a loss or a delay on that job cannot threaten the survival of the company.

In Plain English

A size limit is a number you set before the call comes. It says: this is the biggest job we will take, however good it looks.

Why It Matters

Why Can One Big Job Sink a Good Contractor?

Overextension is the first reason contractors fail in a Miami-Dade chapter article for the Construction Financial Management Association. Too much work drains working capital, and in the author’s words, “Construction companies go out of business because they have no cash.” Source: Grassi and Co., CFMA Miami-Dade.

Growth in volume, type of work, or territory that runs faster than your resources is a known failure factor, according to a surety’s guidance for growing contractors. That surety says 5% to 10% growth a year is probably a good goal, and that 30% to 50% growth may stretch your financials. Source: Old Republic Surety.

A bigger job also means more payroll before the first payment, more subs you may not know, and a schedule that fights with your other work. The cash gap gets deeper, and the owner gets stretched thin. This is Failure #4 in the book.

Signs a job is too big:

  • The job could be a third or more of your year.
  • You said yes before you checked your schedule.
  • You would need subs you have never used.
  • No one but you could run it.
  • The deposit would go to finish jobs that are already late.
  • Your surety agent or banker has not seen the job.
Three or more? Say yes only after the test below, not before.

What It Looks Like

What It Looks Like: The Whole House

From the book · Failure #4 · A fictional example

A couple asks Danny Pruitt to redo an older house: kitchen, three baths, floors throughout, two walls opened up, a new laundry room, and updated electrical and plumbing. The job is worth about a third of Shiny Nail Remodeling’s year. Danny says yes on the spot. He already has two kitchens and a bath underway.

A whole house is not five small jobs stacked up. It needs trades Danny does not usually manage, a structural engineer, and permits and inspections in the right order. It needs Danny too, because he still will not let his helper run anything alone. He splits himself four ways. The kitchens slip. The homeowners start calling every day.

The deposit is the biggest check the company has ever received, and part of it goes to finish the jobs that are already late. Danny is a fictional character in the book.

The Fix

The 5-Part Size Test Before You Say Yes

Run these five checks on every job above your normal size. If any one fails, change the deal or pass.

  1. The cash test.

    Estimate your monthly costs on the job and how many months pass before the first payment arrives. Multiply them. Can you fund that without touching payroll for your other jobs?

  2. The bonding and capacity test.

    Ask your surety agent or banker what they would support. Rules of thumb vary: one surety guide says underwriters apply 10 to 20 times working capital and rarely approve a job above 3 times your largest completed job. Another CPA firm says about 10 times net working capital. Your surety decides, not a formula.

  3. The people test.

    Name the crew lead who runs this job without you. If the answer is you, the job is too big. See how to build crew leads.

  4. The schedule test.

    Put the new job on the calendar next to every job you already have. Where do the same people end up in two places?

  5. The loss test.

    Ask what happens if the job loses 10% or 20% of its value. If the company does not survive that, the job is too big, however good the price looks.

Dr. Paul’s Insight

Write the limit down before the call comes. Many owners use a simple rule: no single job above a set share of the last 12 months of sales, and no job above the cap your surety will support, whichever is lower. Set the percent with your accountant. The point is to decide when you are calm, not when the customer is on the phone.

Worked Example: Setting a LimitYour largest completed job is $400,000. The “3 times your largest job” rule caps the next job at $1,200,000.Your working capital is $300,000. At 10 times, that suggests $3,000,000. The lower number controls: $1,200,000.Now the cash view. A $600,000, six-month job costs about $100,000 a month. If the first payment arrives around day 75, about 2.5 months of costs, or $250,000, go out first. That is 83% of your $300,000 working capital.Rules of thumb vary by surety and the example numbers are illustrations. They are not a prediction for your company.

Saying Yes Safely

Ways to Take a Big Job Without Betting the Company

Turning down work is not the only option. These moves can shrink the risk.

  • Phase the job. Price and bill it in stages, so each stage pays for the next.
  • Ask for a larger deposit or earlier draws so the customer funds more of the early cost. Plan the retainage effect on your cash.
  • Bring in a partner. Team up with a larger contractor or a sub with a track record on this type of work.
  • Staff before you start. Hire or promote the crew lead before signing, not after the schedule slips.
  • Talk to your surety and lender early. A bonding conversation before the bid is easier than one after you win.
  • Say no politely. A clear “not this year, but call me next time” keeps the door open.
What We Could Not Find

We did not find a sourced Florida case of a contractor failing from one oversized job, so this page does not claim one. The pattern comes from failure research, surety guidance, and the book.

FAQ

Job Size Questions

How big a job should a small contractor take?
Big enough to grow on, but not so big that a loss on it would sink the company. Set a written size limit with your accountant, banker, or surety agent, and stay well inside your bonding capacity. Before signing a bigger job, check that you have the cash, the crew leaders, and the subs to run it without pulling them off other work.
How do I know if a job is too big for my company?
Run the five tests: cash, bonding capacity, people, schedule, and loss. If you cannot fund the early costs, no one but you can run it, or a 10 to 20 percent loss would end the company, the job is too big as offered.
What is bonding capacity?
Bonding capacity is the most work a surety company will guarantee for you, on one job and in total. A surety bond promises the customer the job will be finished. It caps how large you can grow on bonded work.
How fast can a contractor safely grow?
No rule fits every company. One surety’s guidance calls 5 to 10 percent growth a year a good goal and says 30 to 50 percent may stretch your financials. Faster growth needs more cash, more crew leaders, and a plan.
What if I turn down a big job and lose the customer?
Offer a phased plan, a partner, or a later start date. If the customer will not wait, you have learned that the job was a bigger bet than the company could carry. Staying open is worth more than one job.
