Construction Industry Accounting Software Explained

Construction industry accounting software exists because a construction company does not make money the way a store or a law firm does. You sell a promise to build something, you spend money for months before the job is done, you bill in pieces, the customer holds back a slice of every payment, and the profit you thought you had on day one can be gone by day ninety. Generic bookkeeping software was never built to show you that.

I ran three restoration companies over 14 years. The first one ran on a basic accounting package and a pile of spreadsheets. I could see my bank balance, but not which jobs were making money until it was too late to fix them. This guide walks through the six things that make construction accounting different, what each one means in plain terms, and the software features that handle each. The goal is to understand what you need the software to do before you look at any product.

What is construction industry accounting software?

Construction industry accounting software is a general ledger, payables, receivables and payroll system built around jobs instead of just accounts. Every transaction carries a job number and a cost code (labor, materials, subcontractors, equipment, other), so you can see cost and profit on each project while it is still running.

In ordinary accounting software, "job costing" often means tagging a bill to a customer and running a report later. In construction accounting software, the job is the backbone. Budgets live on the job, commitments (purchase orders and subcontracts) post against the job before the bill arrives, change orders update the contract value, and billings are measured against what the job has actually earned.

Here are the six differences in short.

1. Job costing: the core of construction accounting

Job costing is the habit of assigning every cost to the job that caused it, broken down by cost code. A cost code is just a bucket: demolition labor, drywall material, electrical sub, dumpster, equipment rental. When every bill, timesheet and receipt lands in the right bucket, you can compare actual cost to the estimate while the job is still open.

On my restoration jobs, labor came from the field and receipts came from three supply houses and a company card. Anything without a job number made the job look more profitable than it was, and we found out at the end.

Job costing features to look for

• Required job and cost code fields on bills, purchase orders, timesheets and expense receipts, so nothing posts without them.
• Budgets by cost code loaded from the estimate, so you see budget against actual line by line.
• Committed costs. A purchase order or subcontract should show up on the job the day you sign it, not the day the bill arrives. Otherwise the job looks healthy right up until the invoices land.
• Change order tracking that updates contract value, budget and billing together.
• Labor burden. Payroll taxes, workers' comp and benefits should be loaded onto job labor, not left sitting in overhead.

Even mainstream products now cover a lot of this. Intuit, for example, lists job costing, budget versus actual, change orders and WIP visibility for QuickBooks Online Advanced on its construction pages as of November 2026. Construction-only systems go deeper. Foundation, for example, advertises unlimited cost codes and real-time WIP reporting on its website. If you are on QuickBooks today, our QuickBooks for contractors setup guide covers how to set up jobs and cost codes properly.

2. The WIP schedule: the report your bank reads first

The work-in-progress schedule, usually called the WIP schedule or WIP report, is a job-by-job table that answers one question: on each open job, have we billed more or less than we have actually earned?

For each job it lists the contract value, the estimated total cost, the cost to date, the percent complete, the revenue earned so far, and the amount billed so far. The difference between earned and billed is the over or under billing.

• Overbilling (billings in excess of costs and estimated earnings) means you have billed ahead of the work. It is recorded as a liability, because you owe the customer that work.
• Underbilling (costs and estimated earnings in excess of billings) means you have done work you have not billed. It is recorded as an asset, but lenders and sureties look hard at it, because it can mean a missed billing, an unapproved change order or a cost overrun dressed up as revenue.

Banks and bonding companies read this closely. Large overbillings on a job with a shrinking margin can mean one job's billings are paying for another job's costs.

WIP features to look for

• A WIP report that pulls cost to date and billings from the ledger automatically, not from a spreadsheet you rebuild each month.
• A place to enter or update estimated cost to complete for each job, with history, so you can see fade or gain over time.
• Automatic over and under billing journal entries at month end. Sage, for example, says on its website that Sage Intacct Construction creates the over and under billing GL entries from its WIP feature. Foundation describes over and under billing posting through its general ledger module.

3. Percent of completion: booking revenue when it is earned

Most small businesses book revenue when they send an invoice. On a long construction job, that can make your financial statements swing wildly: a big progress bill makes one month look great, and the next month, with all cost and no bill, looks like a disaster.

Percent of completion fixes that by recognizing revenue as the work is done. The most common way to measure it is cost to cost:

Everything depends on the estimated total cost. If it is wrong, so is the earned revenue, which is why a good system makes it easy to update cost to complete every month.

There are accounting and tax rules here. Under GAAP, construction revenue generally falls under ASC 606, which recognizes revenue over time when certain conditions are met. For federal tax, IRC Section 460 generally requires the percentage of completion method on long-term contracts, with an exception for smaller contractors that meet an inflation-adjusted gross receipts test and expect to finish the contract within two years, and a separate exception for many home construction contracts. Book and tax numbers can differ, so work this out with a construction CPA. The software's job is to hand them clean data by job.

4. Retainage: the money you earned but cannot collect yet

Retainage (also called retention) is the share of each progress payment the owner or general contractor holds back until the job is finished. The percentage is set in the contract and, in many states and on many public jobs, limited by law. If you are a subcontractor, the GC holds retainage from you. If you are a GC, you hold retainage from your subs at the same time. So the software has to track both sides.

Retainage is where I have seen money quietly disappear. The job closes, the crew moves on, and nobody sends the release request with the closeout paperwork.

Retainage features to look for

• Retainage receivable tracked separately from the current amount due on each progress invoice, by job.
• Retainage payable withheld from subcontractor bills automatically at the right percentage.
• Release billing: a clean way to bill retainage when the job reaches substantial completion, without re-entering the contract.
• AIA-style billing (G702 application and G703 continuation sheet format) if you bill GCs or owners who require it.

Not every product handles this natively. Intuit's materials, for example, point contractors who need retainage tracking and schedule-of-values billing beyond standard progress invoicing toward Intuit Enterprise Suite rather than QuickBooks Online Advanced. Construction-specific systems generally build retainage into receivables and payables from the start. For the collection side of retainage, see our contractor's guide to construction accounts receivable.

5. Certified payroll and prevailing wage

If you work on federally funded or federally assisted construction covered by the Davis-Bacon and related acts, you have to pay prevailing wage rates and fringe benefits for each worker classification, and submit certified payroll every week. The Department of Labor's rules (29 CFR 5.5) require contractors and subcontractors to submit weekly payrolls with a signed statement of compliance. The DOL's WH-347 form is optional, but it is the format most agencies recognize, and the records have to be kept for three years after the prime contract work is complete. Many states have their own prevailing wage laws and reporting systems on top of that.

Generic payroll falls apart here. The same electrician might earn one rate on a private service call and a prevailing rate plus fringes on a public job the same week.

Certified payroll features to look for

• Wage rates set by job and classification, applied from the timesheet.
• Fringe benefit handling, including cash fringes and union fringes.
• Multi-state and local tax handling for crews who cross lines.
• WH-347 style weekly reports and, where your state requires it, electronic upload. Foundation, for example, says on its website that it can upload certified payroll to California's DIR and to LCPTracker.

6. Equipment costing

An owned excavator, lift or truck costs money every month, on a job or in the yard. Generic software spreads that cost across overhead, which hides the real cost of the jobs that used it.

Construction accounting software treats equipment more like a sub you own. You set an internal hourly or daily rate for each piece, charge that rate to jobs from the timesheet, and compare the revenue those charges generate against what the equipment actually costs to own and run.

Equipment features to look for

• Equipment hours or days entered on the same timesheet as labor, by job and cost code.
• Internal billing rates by piece or class of equipment.
• Cost history: fuel, repairs, maintenance, insurance and depreciation by unit.

Larger systems such as Trimble Viewpoint's Vista and Spectrum and Sage 100 Contractor list equipment management on their websites. If you own two trucks and rent the rest, an equipment cost code may be enough.

The rest of construction industry accounting software: AP, AR and billing

A construction ledger still has to do the basics, each with a construction twist.

• Accounts payable needs subcontract tracking, lien waiver and insurance certificate checks before payment, and retainage payable. If you are fuzzy on how the two sides relate, our explainer on accounts payable vs accounts receivable lays it out.
• Billing needs progress billing against a schedule of values, time and materials billing, and change order billing that ties back to the contract.
• Accounts receivable needs aging by job and customer, retainage shown separately, and a way to see what each customer owes across several projects. Our guide to reading an aging report shows what to look for each week.

Where receivables fit next to your accounting system

My first real construction accounting package recorded every invoice beautifully and did nothing to get them paid. The ledger knows a progress bill is 45 days old. It does not send the reminder or follow up on the retainage release. Somebody in the office has to, and when the office gets busy, it does not happen.

That is the gap AR Workflow fills. To be clear about what it is and is not: AR Workflow is not accounting software, not AP software and not a general ledger. It is construction accounts receivable software that sits next to QuickBooks Online and works the receivables side. It reads your open invoices, puts each one on a follow-up schedule, and sends automated emails, two-way texts and ringless voicemail from a dedicated number. Homeowners get a payment link so they can pay from their phone, and an aging dashboard shows who owes what and who has gone quiet. Your accounting system stays the system of record. If you run QuickBooks Online, see how it works with QuickBooks collections, or read more about contractor accounts receivable automation.

On insurance work, it treats adjusters and carriers differently from homeowners. Adjusters get status requests and documentation, never a payment link. For the follow-up process itself, see how to reduce late payments in construction and how to collect unpaid construction invoices.

Frequently asked questions

What is the difference between construction accounting and regular accounting?

Regular accounting tracks the business as a whole. Construction accounting tracks each job as its own profit center, recognizes revenue as work is completed on long contracts, and handles retainage, change orders, certified payroll and equipment costing that most businesses never deal with.

Do I need construction industry accounting software, or is QuickBooks enough?

It depends on your work. Many small residential contractors run well on QuickBooks with jobs and cost codes set up properly. Once you need retainage on both sides, AIA billing, a WIP schedule for your bank, or certified payroll, check carefully whether your edition handles those in the ledger or whether you are building workarounds.

What is a WIP schedule in construction?

A work-in-progress schedule lists each open job with its contract value, estimated cost, cost to date, percent complete, earned revenue and billings to date. The difference between earned revenue and billings shows whether the job is overbilled or underbilled.

How is retainage recorded in construction accounting?

Retainage you are owed is recorded as retainage receivable, separate from current receivables, until the contract allows you to bill for its release. Retainage you hold back from subcontractors is recorded as retainage payable. Good software tracks both by job.

Does construction accounting software collect payments?

Most systems create invoices and record payments, and some offer online payment options. Few do the ongoing follow-up: reminders, texts, calls and escalation on late bills. That is usually handled by your office staff or a separate receivables tool such as AR reporting software that works alongside the ledger.
