The 10% You’re Not Getting Paid — And What It’s Really Costing You

The 10% You’re Not Getting Paid

Retainage is essentially an interest-free loan you’re giving your clients — usually 5 to 10% of every invoice, held until the job’s done. On one job, that’s manageable. But run three or four concurrent jobs, and that retainage stacks up fast, tying up cash you need right now for payroll and materials.

It also flows downhill: you’re often passing retainage through to your own subcontractors, which creates its own lien risk if it’s mismanaged. The good news is that retainage percentage and release terms are often negotiable, and the cash it ties up can be forecasted instead of absorbed as a surprise.

How Retainage Works Mechanically

Retainage is a percentage of each progress payment — typically 5% to 10% — that the owner withholds from every invoice and holds until a specified release point, usually substantial completion, final completion, or the expiration of a warranty or lien period. The withheld amount isn’t a penalty or a dispute; it’s a standard contractual mechanism owners use to ensure the work gets finished and any post-completion issues get resolved before the last dollar changes hands.

The specifics vary significantly by state and by whether the project is public or private. Many states cap retainage on public projects, some require early release once a project reaches a certain percentage of completion, and some prohibit retainage on change order work entirely. Private contracts have more flexibility, which means the terms are largely whatever gets negotiated into the contract — for better or worse. Reading your actual contract language, rather than assuming a standard rate applies, is the first step in understanding what you’re working with on any given job.

The Compounding Problem: Retainage Across Concurrent Jobs

A single job’s retainage is usually a manageable, known quantity. The real strain shows up when several jobs are running at once, each holding back its own slice of cash that won’t be released for months. Here’s a simplified illustration of four concurrent jobs:

Job Contract Value Retainage % Retainage Held
Job A
$500,000
10%
$50,000
Job B
$750,000
5%
$37,500
Job C
$300,000
10%
$30,000
Job D
$600,000
5%
$30,000
Total tied up across 4 jobs
$147,500

That’s $147,500 tied up and unavailable for payroll, materials, or overhead — money you’ve legitimately earned but won’t see until each job reaches its release point. For a contractor running a lean cash position, that gap is often the difference between a comfortable quarter and a scramble to cover costs on work that’s already done.

Retainage vs. Your Own Subcontractors

Retainage rarely stops with you. Most general contractors pass the same retainage percentage — or close to it — down to their subcontractors, withholding a portion of each sub’s payment until the same release conditions are met. Handled correctly, this keeps your own cash exposure in line with what the owner is holding back from you.

Handled poorly, it becomes a lien risk. If retainage held from subs isn’t tracked accurately, released on time, or reconciled against what you’re actually holding from the owner, subs can end up unpaid for work they completed — and an unpaid subcontractor with a valid claim can file a lien against the project, regardless of whether the delay was intentional or just a bookkeeping gap. Clean retainage tracking protects you on both ends of that relationship.

Negotiation Lovers

Retainage percentage and release terms are more negotiable than most contractors assume, especially with an established track record or on larger contracts where the retained dollar amount becomes significant to both sides. A few levers worth raising during contract negotiation:

  • A reduced retainage percentage — many owners will negotiate down from 10% to 5% depending on the relationship and nature of the work, particularly as the project approaches substantial completion.
  • A stepped-down or early release schedule — reducing a portion of retainage, or the retainage rate on remaining invoices, once the contractor’s work is substantially complete, rather than holding the full amount until turnover.
  • Eliminated retainage for early, self-contained scopes — trades like demolition or site clearing finish their work long before the project reaches completion, and that work has little to no bearing on whether the finished project is ultimately accepted — which makes it worth arguing that retainage on their invoices should be reduced or waived rather than held to the same closeout date as every other trade.

None of these are guaranteed, and leverage depends heavily on your relationship with the owner and the competitiveness of the bid. Yet retainage terms are a line item in the contract like any other — worth raising at negotiation time rather than simply accepting whatever flows down from the contract above you.

Forecasting Around Retainage Instead of Getting Surprised by It

Retainage shouldn’t be a surprise that shows up as a cash crunch near a job’s end. Because the percentage and release triggers are known at contract signing, retainage is one of the more predictable line items in a cash flow projection — but it should be built into one. A cash flow forecast that includes expected retainage release dates, job by job, turns a vague sense of “money we’re owed eventually” into a specific amount you can plan to collect when it’s due.

A Simple Retainage Tracking Approach

Tracking retainage well doesn’t require new software — it requires tying it to the job costing you’re already doing:

What a clean retainage tracking approach includes:
  • Retainage held by the owner, tracked per job — the running total withheld from your invoices, updated as each pay application is submitted.

  • Retainage passed through to subs, tracked per job — so you can confirm what you owe them lines up with what you’re holding from the owner.

  • An expected release date for each job — tied to substantial completion, final completion, or whatever trigger the contract specifies.

  • A monthly roll-up across all active jobs — so total retainage exposure — and when it’s expected to convert to cash — is visible at a glance, not discovered job by job.

Not Sure How Much Retainage Is Actually Tying Up Your Cash?

If you’ve never built retainage into a real cash flow forecast, or you’re not sure how much is currently held across your active jobs, we can help. We’ll build a cash flow projection that accounts for retainage timing job by job, so you can see what’s coming and when. Reach out to schedule a retainage and cash.
