What does it mean when a construction line of credit is always maxed?

It means the LOC is being used as a permanent operating tool instead of a short-term bridge — which signals a structural cash timing problem that hasn't been fixed. The causes are almost always: uncollected AR, late pay app submission, an overhead rate in bids lower than actual overhead, or growth outpacing the billing system.

How do I pay off my construction line of credit?

The fastest path is AR collection — most contractors with a maxed LOC have $80,000–$300,000 in uncollected invoices. Calling on that AR generates cash without new work or new financing. Simultaneously fixing the billing calendar stops the LOC from refilling. Most SPM clients pay off their LOC within 60–90 days of engagement from these two changes alone.

Should I get a bigger line of credit?

Only if you've already fixed the underlying billing structure problem. A bigger LOC on a broken billing system just gives you a higher ceiling to max out. Fix the AR collections, billing calendar, and overhead rate first. Once the LOC is paying down consistently, increasing the limit is a reasonable growth tool — not a cash fix.

What is the right way to use a construction line of credit?

Draw it down when a specific timing gap requires it — a new job starting before an existing pay app is received, or a large material order that precedes billing. Pay it back when the corresponding payment arrives. The LOC balance should go to zero at least once per quarter. If it never pays down, the underlying cash flow structure isn't working.

How does SPM help contractors pay off their LOC?

SPM starts with an AR audit to generate immediate cash from outstanding invoices, then rebuilds the billing calendar to prevent timing gaps from recurring. Most clients see the LOC balance drop significantly in the first 30–60 days from AR collection alone. The 13-week cash flow forecast shows the payoff trajectory clearly.

TL;DR: A maxed construction line of credit signals a structural cash timing problem — the LOC is being used as a permanent operating tool instead of a bridge. The fix is AR collection first (most contractors have $80K–$300K uncollected), then rebuilding the billing calendar to stop the LOC from refilling. A civil contractor client paid off $348,000 in LOC debt in 60 days through these two changes alone. Getting a bigger LOC doesn't fix the problem — it just gives you more room to max out.

Cash Flow Crisis

Line of Credit Maxed Out.
Here's How Contractors Get Off It.

The LOC is full. Cash is still tight. Getting a bigger one won't fix it — you'll just fill that one too. The problem is in the billing structure, not the credit limit.

Root Cause

Why the LOC Got Maxed In the First Place

A line of credit is designed to bridge a short-term timing gap — draw it down when cash is temporarily short, pay it back when the next payment comes in. When the LOC is permanently drawn and never pays down, the timing gap isn't temporary. It's structural. The underlying cash flow problem hasn't been fixed, so the LOC just stays full — and eventually you hit the limit with cash still tight.

Signs the LOC Is Being Misused

Balance never goes below 70% of limit

You draw on it every month regardless of job status

Had it 2+ years and it's never been paid off

You renewed or increased it instead of paying it down

Balance goes up when you win more work

You think of it as part of your operating cash

What's Actually Causing It

Pay apps submitted late — pushing payment 30 days

AR over 45 days nobody is calling on

Overhead rate in bids lower than actual overhead

Retainage counted as available cash when it isn't

New jobs starting faster than old cash comes in

No 13-week forecast — gaps invisible until critical

Don't Get a Bigger LOC

The natural instinct when the LOC is maxed is to call the bank and ask for a higher limit. That buys time. It does not fix the problem. A contractor who maxes a $200,000 LOC and gets a $350,000 LOC will max that one too — usually faster, because they're growing. Fix the billing structure first. The LOC payoff follows automatically.

The Fix

How to Pay Off the LOC Without New Financing

1. AR Audit — The Fastest Cash Source

Pull every invoice over 30 days and call on all of them this week. Most contractors at LOC max have $80,000–$300,000 in uncollected AR. That cash is already earned. The first round of collections alone typically makes a material dent in the LOC balance.

2. Fix the Billing Calendar — Stop the Bleeding

Map every GC's pay app cut-off date. Submit on the first eligible day of every period. One missed cut-off on a $400,000/month job delays $400,000 by 30 days. Fix the calendar and the LOC stops growing — immediately.

3. Correct the Overhead Rate in Bids

If you're funding overhead from what you thought was gross profit, every job you win makes the cash problem slightly worse. Correct the rate in the next bid. Start there.

4. Build a 13-Week Cash Flow Forecast

Once AR is collected and the billing calendar is fixed, map the 13-week picture. You'll see the LOC payoff date clearly — and any future timing gaps that need a plan before they become emergencies.

Client Outcome

What This Looks Like In Practice

Anonymous Client — Civil Contractor · $6.7M Revenue

This contractor came to SPM with a $348,000 line of credit fully drawn and an MCA on top of it. The business was profitable. But the LOC had never paid below $200,000 in three years — it was a permanent fixture in the operating cash picture.

LOC $348,000 → $0

In 60 days. Not from new work or new financing. From collecting AR that had been sitting uncollected and fixing the pay app timing on three active jobs.

$65,000

In employee bonuses paid after the LOC was cleared. The same cash that had been cycling through the LOC was now staying in the business because the billing structure wasn't creating the gap anymore.
