Unpaid Income Tracking for Construction and Contractors in Austin

Unpaid income tracking for a construction contractor in Austin means keeping a clear, current picture of all the money you have earned but have not yet billed or collected, which on a construction job is a much bigger and more slippery number than at an ordinary business. At most companies, income you have earned and income you have billed are the same thing, you deliver, you invoice, done. On a construction job they come apart, because you produce revenue by putting work in place continuously, but you only bill for it periodically through payment applications, and you collect it later still after retainage is held back. The result is that at any given moment you have earned income sitting in three different states, some billed and collected, some billed and not yet paid, and some earned but not even billed yet, and in a boom with several jobs running the number of places that money can sit only grows.

That last category, earned but unbilled, is the heart of unpaid income tracking, because it is the easiest to lose. It shows up in two main forms. The first is underbilling, where the work you have actually completed is further along than what your payment applications have claimed, so you have performed work you have not asked to be paid for. The second is the unbilled change order, extra work done on a verbal instruction that was never formally priced, approved, and invoiced. Both represent real money you earned and paid your crew to produce, and both can vanish at the end of a job if nothing is tracking them.

The tool that makes this visible is the work-in-progress schedule. Here is a worked example. Suppose on a single job you have incurred 700,000 dollars of cost against a 1,000,000 dollar estimate, so you are 70 percent complete, and the contract is worth 1,300,000 dollars, meaning you have earned 910,000 dollars. But your payment applications total only 820,000 dollars. The WIP schedule immediately shows a 90,000 dollar underbilling, earned income you have not yet billed, which you can then invoice on the next application instead of discovering it missing at closeout. Without the WIP, that 90,000 dollars is invisible until it is too late to catch.

We keep the WIP schedule current so your earned, billed, and collected numbers are always clear and the unbilled earned income is caught while you can still bill it, working through our bookkeeping. We build on the percentage-of-completion rules in Section 460 and the recognition guidance in IRS Publication 538. For a contractor, unpaid income tracking is really the discipline of making sure every dollar you earned actually gets billed and shows up in your numbers, rather than leaking away unnoticed. The contractors who lose the most are usually not the ones doing bad work, they are the ones doing plenty of good work but never billing all of it, because nothing on their books told them a gap had opened between what they built and what they invoiced. A current schedule closes that blind spot and turns earned work into money on the next application instead of a write-off at the end.

For an Austin construction contractor, earned income, billed income, and collected income are three genuinely different numbers on the same job, and understanding the difference is the foundation of tracking your money correctly, because contractors who treat them as the same thing lose track of what they are actually owed. Earned income is the revenue you have produced by putting work in place. Under the percentage-of-completion method that governs most long-term contracts, you earn revenue in proportion to the cost you have incurred against the total estimated cost, so if you are 60 percent of the way through the budgeted cost, you have earned 60 percent of the contract value, whether or not you have billed a dime of it.

Billed income is what you have formally requested payment for through your payment applications. Because applications go in on a periodic cycle, usually monthly, and have to be reviewed and certified, billing always lags the actual work. You might be 60 percent complete in earned terms but have only billed for 55 percent because the current application has not gone in yet, or you underestimated completion on the last one. Collected income is what has actually landed in your bank account, which lags billing again, because even a certified application takes thirty to sixty days to fund, and retainage, commonly 5 or 10 percent in Texas, is held back from each payment until the job is accepted. So collected always trails billed, which trails earned.

Here is a worked example that shows all three at once. On a 1,000,000 dollar contract you are 50 percent complete by cost, so you have earned 500,000 dollars. You have submitted payment applications for 450,000 dollars, so that is billed. Of that, the owner has paid all but the retainage and the most recent pending application, so perhaps 380,000 dollars has been collected. At this snapshot you have earned 500,000 dollars, billed 450,000 dollars, and collected 380,000 dollars, three different numbers describing the same job. The 50,000 dollar gap between earned and billed is an underbilling you should catch and invoice, and the 70,000 dollar gap between billed and collected is money to chase and retainage to track.

Keeping these three straight on every job is what the work-in-progress schedule does, and it is why we maintain it as part of your regular reporting through our monthly financial reporting. We build on the method rules in Section 460 and the accounting-method guidance in IRS Publication 538. For a contractor, knowing the difference between earned, billed, and collected is what turns a vague sense that money is out there into a precise number you can act on. Each of the three gaps has a different job attached to it, the earned-to-billed gap tells you what to invoice, the billed-to-collected gap tells you what to chase, and the retainage slice tells you what to watch for at closeout. A contractor who can name those three numbers on every active job is far harder to surprise than one who only watches the bank balance and hopes it all works out, which matters even more when a boom has you running more jobs than you can hold in your head.

Underbillings and unbilled change orders cost an Austin contractor money because they represent work you have already performed and paid for but have not invoiced, and if they are not caught and billed, they can simply never get paid, turning real earned profit into a permanent loss. An underbilling occurs when the revenue you have earned on a job, based on how far along you actually are by cost, exceeds what you have billed on your payment applications. It usually happens because completion was understated on an application, or because billing fell behind the pace of the work, which is easy in a boom when the field is moving faster than the paperwork. The danger is that an underbilling is invisible on a cash-basis view, the bank balance looks fine, so a contractor without a work-in-progress schedule may never realize a chunk of earned work was left unbilled until the job closes and it is awkward or impossible to go back and bill it.

Unbilled change orders are the sharper version of the same problem. Construction work changes constantly, and on a busy Austin site a general contractor or owner often tells a sub to proceed with extra work verbally, promising the paperwork will follow. If that extra work is performed but never formally priced, approved in writing, and added to a payment application, it becomes earned income with no invoice behind it and no signed authorization to enforce it. When the job ends and you try to collect, the other side may dispute that the change was ever authorized, and without documentation you may eat the cost entirely. Change orders are consistently the most disputed and most frequently lost category of construction income.

Here is a worked example. Suppose on a job you are underbilled by 90,000 dollars because your applications lag your actual completion, and separately you performed a 25,000 dollar change order on a verbal go-ahead that was never invoiced. That is 115,000 dollars of earned income at risk on a single job. If your net margin on the job was supposed to be 100,000 dollars, failing to catch and bill that 115,000 dollars does not just reduce your profit, it can turn the entire job into a loss, because you paid your crew and suppliers to produce that work but never collected for it. Catching it in time to bill it is the difference between the job’s real profit and a painful write-off.

We track underbillings and unbilled change orders against every job through the work-in-progress schedule, flagging them while there is still time to bill and, for change orders, pushing to get the written authorization before the work goes too far, working through our monthly financial reporting. Once the earned income is properly billed, we hand it to the collection side through our receivables and collections. For a contractor, catching underbillings and unbilled changes is often the single highest-value thing tracking does, because it recovers money that would otherwise disappear. On change orders in particular, the habit that protects you is refusing to let extra work get far without written authorization, and a good tracking system makes that a routine step rather than an afterthought, so the extra work you perform is always work you can bill and enforce. Recovered underbillings and documented changes routinely add up to more than the cost of the tracking many times over across a year of jobs.

Untracked earned income directly distorts an Austin contractor’s taxes, because the percentage-of-completion method taxes you on income as you earn it rather than when you bill or collect it, so if your earned income is tracked wrong, your tax is wrong, though in Texas the error is contained to the federal return because there is no state income tax. Under the method, your taxable income for the year on a long-term contract is driven by how complete each job is by cost, which means the accuracy of your tax depends entirely on the accuracy of your job cost and your work-in-progress schedule. If those are stale or wrong, the earned income they produce is wrong, and so is the tax computed from it.

The distortion runs in both directions. If your earned income is understated, because the WIP has not kept up and shows jobs as less complete than they really are, you report too little income and pay too little tax, which feels fine until a method exam recomputes your completion using the real cost data and assesses the additional tax plus interest, sometimes on a year you considered long settled. If your earned income is overstated, you pay tax early on profit you have not actually made, tying up cash you need for the work. Neither is good, and both come from the same root, earned-income tracking that does not reflect reality. Here Texas is genuinely easier than a high-tax state, because the same error in California would flow to both the federal and the state return at once and be taxed again at a state rate reaching 13.3 percent, while in Texas it touches only the federal return. The one Texas interaction is the franchise tax, where for a contractor over the roughly 2.47 million dollar revenue threshold the recognized revenue feeds the margin, so an earned-income figure that is off can move the franchise-tax margin even though there is no state income tax.

Here is a worked example. Suppose your WIP is out of date and shows your active jobs as 50 percent complete when clean job cost would show them at 60 percent. On a portfolio of contracts worth 2,000,000 dollars, that ten-point understatement means you have underreported roughly 200,000 dollars of earned income. At a federal marginal rate around 30 percent with no state income tax to add, that is about 60,000 dollars of tax you did not report for the year. If a method exam later corrects the completion, you owe that 60,000 dollars plus interest, an unpleasant surprise that accurate tracking would have avoided entirely by reporting the right income in the first place. A California contractor would face that same federal amount plus a state bill on top, so the Texas contractor is better off, but 60,000 dollars plus interest is still a surprise worth avoiding.

We keep the job cost and WIP accurate so the earned income that drives your tax is right, and we size your quarterly estimates, due on the 2026 federal dates of April 15, June 15, September 15, and January 15, 2027, to real earned profit, with no state estimate to match, working through our tax strategy consulting. We build on the method rules in Section 460 and watch the franchise-tax margin under the Texas Comptroller rules for a contractor near the threshold. For a contractor, accurate earned-income tracking is not just good management, it is what keeps your tax correct and your closed years actually closed. The worst version of this is paying tax twice over, once when a stale WIP overstates income in one year and again when the correction lands in another, and clean tracking is what prevents that whipsaw. It also means your quarterly estimates are sized to real profit rather than a guess, so you are neither starving your cash by overpaying nor setting up a penalty by underpaying.

We track unpaid and unbilled income for an Austin contractor by building and maintaining a current work-in-progress schedule tied to clean job cost, which is the one tool that makes every earned dollar visible and catches the money before it leaks, and we run it as an ongoing discipline rather than a once-a-year cleanup. The starting point is accurate job cost. Every labor hour, material invoice, subcontractor payment, and equipment charge has to be coded to the specific job it belongs to, because the whole earned-income calculation under percentage-of-completion depends on knowing the cost incurred on each job against its total estimate. If the job cost is sloppy, the earned income it produces is unreliable, so we keep the coding disciplined from the first transaction, which matters even more in a boom when the sheer volume of transactions across many jobs makes sloppy coding easy.

From that clean job cost we build the WIP schedule, which lists for each active job the total contract value, the estimated total cost, the cost incurred to date, the resulting percent complete, the revenue earned, the amount billed, and the over- or underbilling. Updated regularly, that schedule immediately surfaces any job where earned income is running ahead of billing, so an underbilling gets flagged while there is still time to put it on the next payment application rather than discovering it at closeout. We pair that with a change-order log that tracks every extra work item from the moment it is requested, so a verbal change gets pushed toward written approval and into billing instead of being performed and forgotten.

Here is a worked example of the process working. Suppose our monthly WIP update shows a job that has quietly become 65 percent complete by cost while the payment applications reflect only 52 percent. That is a 13-point underbilling, and on a 900,000 dollar contract it represents about 117,000 dollars of earned income not yet billed. Because the WIP caught it this month, you add it to the next application and collect it on schedule, instead of finishing the job, forgetting the gap, and writing off six figures of work you already performed. The tracking turned an invisible leak into billed, collectible revenue.

We run the WIP and the change-order tracking through our monthly financial reporting, keep the underlying job cost clean through our bookkeeping, and once income is billed we support the collection of it as well. We build on the percentage-of-completion rules in Section 460 and the recognition guidance in IRS Publication 538. For a contractor, this tracking is how earned income stops slipping through the cracks and starts showing up where it belongs, on your invoices and in your bank account. The value grows with the size and number of your jobs, because the more work you have running at once, the more places earned income can hide, and the harder it is to hold the whole picture in your head, which is exactly the situation an Austin contractor is in during a boom. A schedule that updates on a regular cadence does that holding for you, so no matter how many jobs are open, the earned, billed, and collected numbers on each one stay in front of you where you can act on them. And because Texas has no state income tax, keeping those numbers right protects your federal return without the added complication of reconciling a separate state figure, so the tracking does its job with one less layer to worry about.
