Debt collection for contractors means recovering unpaid invoices without burning the referral relationships your business runs on.

You did the work. The job passed inspection. The customer — or the general contractor above you — has your invoice. And week after week, the money doesn’t come.

For contractors and skilled-trades businesses, unpaid receivables aren’t an accounting nuisance. They’re payroll you’ve already met, materials you’ve already bought, and equipment payments that don’t wait. This guide covers why construction receivables go bad, the warning signs to watch, what to try in-house, and when it’s time to bring in debt collection for customers and subcontractors who won’t pay.

Debt Collection for Contractors: Every Trade Has Its Own Version of the Problem

General contractors and subcontractors

Payment chains are the core issue. When you’re a sub, your money often waits on the GC getting paid — and “pay-when-paid” language can leave you financing someone else’s project. Retainage held past substantial completion, change-order disputes, and punch-list stalling are all common ways a legitimate invoice can quietly become stale.

Roofing companies

Insurance-funded jobs add a third party to every payment. Supplement disputes, depreciation checks that arrive at the homeowner and never reach you, and customers who “wait on the adjuster” for months are recurring patterns. Storm-season volume also means invoicing sometimes lags the work — and older invoices are harder to enforce.

Plumbing contractors

Emergency work is a collections trap: the customer approves the repair at 2 a.m. when the basement is flooding, then disputes the price once the water is gone. Commercial service accounts that quietly stretch from net-30 to net-90 are the slower version of the same loss.

HVAC companies

Big-ticket installs (a full system replacement) mixed with small recurring service invoices means one bad commercial account can equal fifty good residential ones. Maintenance-agreement customers who stop paying but keep calling for service deserve a hard look at their aging balance.

Electrical contractors

New-construction and remodel work exposes electricians to the same GC payment-chain problems as other subs, while service work brings the disputed-scope problem: “I didn’t authorize that panel upgrade.” Documentation — signed work orders, photos — decides these arguments.

Warning signs that an account is going bad

Watch for these at each stage of aging:

  • 30 days past due: the customer stops answering the phone number that used to pick up, or starts routing you to a different person each time.
  • 60 days past due: you hear a new dispute about work that was accepted without complaint at completion. Late-arriving disputes on old invoices are frequently a payment-avoidance tactic, not a quality issue.
  • 90+ days past due: promises to pay have been made and missed more than once, or you learn the customer has new projects underway while your invoice sits. At this point, the account needs escalation, not another reminder email.

A general reality every contractor knows from experience: the older a receivable gets, the harder it is to collect. Waiting rarely improves the outcome.

What to try in-house first

Before escalating, make sure you’ve done the basics — they resolve many accounts and strengthen the ones that do need escalation:

  1. Invoice immediately and accurately. Same-day or next-day invoicing with the signed work order or contract attached removes the easiest excuses.
  2. Follow a fixed reminder cadence. For example: a friendly reminder at 15 days, a call at 30, a formal past-due letter at 45–60. Consistency signals that you track your money.
  3. Know your lien rights. Indiana and Kentucky both provide mechanic’s lien remedies for construction work, and lien deadlines are strict and time-limited. This article can’t give legal advice — confirm current deadlines and notice requirements for your situation with the statute or a construction attorney, because missing a lien window closes a powerful door.
  4. Get every change order in writing. Most “disputes” are really documentation gaps.
  5. Stop work on chronic non-payers where your contract allows it. Throwing more labor at an account that isn’t paying deepens the loss.

When it’s time to bring in a collection agency

Escalate when the pattern is clear: 90+ days past due, broken promises, a dispute that appeared only after the bill did, or a customer who has simply gone silent. That’s when debt collection for contractors through a professional agency, compliant with the Fair Debt Collection Practices Act (FDCPA), is worth more than your time chasing the last job.

Here’s what placing an account with New World Collections looks like:

  • You stay in control. No binding contracts — you choose which accounts to place and which program fits.
  • Placement takes minutes. Our online gateway lets you submit accounts directly, and it scales whether you have one problem account or hundreds.
  • A professional third party changes the conversation. A collection agency contacting your customer signals that the invoice will not be forgotten — while keeping you out of the uncomfortable calls.
  • A track record you can verify. NWC has collected commercial debt since 1997, holds an A+ complaint-free rating with the BBB, and has a 5.0 Google rating across 500+ reviews — from offices in Indianapolis and Columbus serving Indiana, Kentucky, and Ohio.

We won’t promise you a recovery percentage — no honest agency can, because every account is different. What we can promise is that a professional, persistent, and lawful effort will be made on every account you place.

Frequently asked questions

How old is too old to send an account to collections?
There’s no single cutoff, but recoverability generally declines as accounts age, and legal deadlines (statutes of limitation) eventually apply. The practical answer: escalate at 90 days rather than at two years.

Will using a collection agency hurt my customer relationships?
You choose which accounts to place. Most contractors reserve collections for customers who have already broken the relationship by not paying — and a professional agency conducts itself in a way that reflects on your business accordingly.

What does it cost?
Fee structures depend on the program and account type. Contact us and we’ll walk you through the options before you commit to anything — no binding contracts.

Can you collect from a general contractor, not just property owners?
Yes. Commercial debt collection includes business-to-business receivables such as unpaid subcontractor invoices.
