Why That Big Builder Account Will Bankrupt You
Why That Big Builder Account Will Bankrupt You
In the spring of 2007, I had six trucks on the road and twelve guys on payroll. Smith Mechanical was doing real numbers. Two builder accounts feeding me steady rough-in work, and I thought I'd figured something out. I was measuring success in trucks.
Eighteen months later I was laying off four men I'd hired personally, watching receivables stretch from 45 days to 110, and trying to remember the last time I had 90 days of cash sitting still. The plumbing was fine. The work was fine. The builder accounts were the problem, and I hadn't seen it coming because the numbers looked so good on the way up.
That's the trap.
The Lottery Ticket Feeling Is a Lie
Here's what a builder account looks like when someone offers it to you. Steady work for the next eighteen months. No marketing spend. No chasing small service calls. You know what's coming, you staff to it, you look like a real operation. The story you tell your wife, your banker, your guys — it's a good story.
The feeling is wrong.
Ask yourself this question on day one, before you sign anything: if this account went completely silent tomorrow, how long could I pay my guys?
Most small shops can't answer that. They don't know the number. And here's the part that should bother you: a big builder account, structured the way builder accounts usually are, is about to make that number smaller. Not bigger. You're going to spend cash staging for their jobs, carrying their receivables, funding their retainage — and meanwhile your service revenue, the work that pays weekly, quietly dries up because you stopped chasing it.
The lottery ticket feeling is real. The lottery ticket ain't.
When One Account Is 40 Percent of Your Revenue, You Don't Have a Client
You have a landlord.
I had two builder accounts in October 2008. Lost both in the same week. Not because anything I did was wrong. The housing market collapsed, the permits stopped, the phones went quiet. There was nothing wrong with my plumbing. There was everything wrong with my revenue mix.
I wasn't in trouble because the work was bad. I was in trouble because I'd stacked good work on top of one basket someone else was carrying. You can show up on time, hit every schedule, and still watch it fall apart if the guy writing your checks decides to stop.
What it looked like after the fact: $61,000 in receivables already stretched past 110 days. No service revenue worth counting because I'd ignored it for two years chasing builder volume. Four layoffs in three weeks — guys I'd recruited myself, conversations I had in a parking lot. That's what this looks like from the inside. Not a spreadsheet. Four conversations.
The rule I use now: no single account above 25 percent of trailing revenue. Not because a consultant told me. Because I watched what happens when you cross that line and the account disappears.
Slow Pay Isn't a Courtesy Problem
It's a theft problem.
A GC running 60-plus days on a net-30 contract is using your labor as a free credit line. He's not confused about the terms. He's made a calculation — you'll keep working, you won't lien, you won't walk, and every week you prove him right the bet gets bigger.
In 2011 I was owed $61,000 by a builder named Whitman out of Marlborough. Four jobs, all over 75 days. Always the same story: next Friday, almost done with the Phase Two closing, you know how it is. I kept working because he was 40 percent of my work and I didn't want to burn a bridge in a small town.
He paid me 38 cents on the dollar in the bankruptcy.
What "next Friday" actually means: he's paying his framer with your money, because the framer threatened to walk and you didn't. You are the rational float because you haven't made floating you painful enough.
Then there's the contract. Pay-when-paid clauses. Retainage provisions. Punch list language that hands the GC control of your final payment. Those aren't boilerplate somebody copied off a form. A lawyer built those tools for exactly this situation — sub needs money, GC needs time. You signed because you wanted the work. He signed because he's done this before.
A pay-when-paid clause doesn't protect you from slow pay. It converts his cash-flow problem into yours, in writing, with your signature on it.
Retainage Is the Part Nobody Talks About at the Handshake
Ten percent sounds small. It doesn't feel small on a long job.
Say you're doing $400,000 of mechanical work on a thirty-unit subdivision. Standard 10 percent retainage. That's $40,000 sitting in the GC's account from the moment you start billing. You'll bill month after month, collect 90 percent each time, and feel fine — right up until substantial completion, when you're looking at $40,000 in holdback and a punch list between you and any of it.
I have watched GCs manufacture punch list items. Touch-up paint outside the scope. A pressure test they suddenly decided needed a third party. A valve they claim was spec'd differently. Not because the work was wrong. Because the holdback gives them a clock to run and the punch list is how they run it. You're not seeing that money until every other sub is paid and the job is closed.
Your recourse is to sue. Suing costs more than the retainage. They know that. So do you, which is why you won't. That's the whole play.
On the 90-day rule: if you're three months into a big builder job and $40,000 in holdback is sitting untouchable, that gap is funded by your cash or your credit line. You're not winning. You're lending.
A Builder Account Isn't Always Wrong
I don't say never take builder work. I've done it. Some of it was fine.
The 2008 crash didn't kill bad shops. It killed undercapitalized shops. There's a difference. A bad shop can survive a long time in a hot market. An undercapitalized shop dies the first time the music stops, no matter how clean the work is.
After Whitman, after the 38 cents, I took on another builder in 2012. Smaller guy. Local custom homes. I held him to 30-day terms in the contract, got a personal guarantee, kept him under 20 percent of my revenue, and pulled a lien on the first job that went past 45 days. He called, furious. I explained the math. We worked together four more years without a single late invoice.
That's the version that works. The difference between that account and Whitman wasn't the builder's character. It was what I had in writing and how fast I was willing to use it.
I fired a different builder in 2013 over a $19,000 receivable that kept getting extensions. Slept better that week than I had in months. Walking away from an account that's drifting isn't a failure. It's Thursday.
What You Do Before You Sign Anything
You've got a builder on the phone with a two-year pipeline and you want to say yes. Do these things first.
Figure out how much of your work this one guy would represent. Pull your trailing twelve months of revenue. Add up what this account would be at full volume. If it's over 25 percent, you've got a problem to solve before you've got a relationship to manage. That's a real number — write it down.
Run the 90-day calculation. Cash in the bank plus credit you can actually pull, divided by your monthly nut — payroll, truck notes, insurance, supply accounts. If the answer is under 90 days, this account isn't an opportunity yet. It's a gamble with your guys' paychecks. Fix the number first. Build your service book, collect your open AR, cut what you can. Get to 90 days before you sign.
Look up your state's mechanics lien deadline before you start work. Pennsylvania is six months from last work performed in most cases. Some states have pre-lien notice requirements you have to send before you've done a dollar of work. If you don't know your state's number, find out this week. Your lien rights are your leverage — knowing them before you negotiate changes what you ask for.
Red-line the pay-when-paid clause. Push for net-30 from invoice date, not net-30 from whenever the owner funds the GC. If they won't move, price the float. A 60-day average pay cycle on significant volume costs real money. Calculate it. Charge for it. Don't eat it and resent them later.
Decide your ceiling before the first fixture goes in. Pick a percentage. Write it somewhere you'll see it. When you hit it, stop taking new work from this account until your total revenue grows enough to bring the number back down. The shops I've seen make builder work work — they made this call in advance, not in a panic when things went sideways.
Builders go bankrupt. Projects get cancelled. GCs get bought out and the new guys renegotiate every sub contract on day one. None of that is in your control. What's in your control is how much of your business they own when it happens.
Make sure it ain't enough to take you with them.
Questions I Get Asked
I've got a builder offering steady work for two years. How do I know if it's too big?
Run the math before you agree to anything. If this account at full volume would be north of 25 percent of your trailing revenue, it's too big right now — not forever, but right now. Two years of steady work evaporates fast when a project gets cancelled or the GC hits a crunch. I've seen it happen inside six months. What feels steady from the outside is somebody else's projection. Your exposure is real either way.
What payment terms should I push for, and how hard?
Net-30 from invoice date. Push hard, in writing, because everything above that is you carrying their operation. Some GCs give you 30 with no argument. Some try to insert pay-when-paid language — that's the one you red-line. If they won't move, price the float and charge for it. Don't absorb the cost and resent them for it by month four.
I'm already in deep with a builder running 75-plus days. What do I actually do?
Stop work on all open jobs until you have a written payment commitment with a real deadline — not a phone call, written. Send a demand letter, certified mail, itemizing every open invoice with amounts and dates. Give them seven days. Then pull your state's lien deadline, because depending on when the work was done, you may be running out of time without knowing it. If they don't respond, file the lien and pull your tools. I know that feels like burning the bridge. I kept working for Whitman and got 38 cents on the dollar. The leverage you have right now is real. Use it before it expires.
Is there a version of a big builder account that actually works for a small shop?
Yes. I ran one from 2012 to 2016 that was profitable and clean. What made it work: 90-plus days of cash on hand before I started, that account under 20 percent of my revenue, net-30 in the contract with a personal guarantee, and I pulled a lien the first time they went past 45 days. He was furious. We worked together four more years without a problem. The version that doesn't work is the version where you need the account too badly to enforce any of those things. That's how you end up in a parking lot telling guys you can't make payroll.
What's the first sign a builder account is turning into a problem?
First time a payment is late and the reason is owner funding, a closing delay, or phase timing — that's the tell. A GC with a healthy job pays you from his operating account and handles the owner timing on his own end. When he starts passing that explanation to you, he's already squeezed. Pull your lien rights that week. Start a paper trail. Don't wait for "next Friday" twice.
