Accounting for Construction & Contractors
A job can look busy and still not be making money, and generic bookkeeping usually can't tell you the difference. We build job costing and progress billing into your books so you know which jobs are actually profitable, not just which ones kept your crew occupied.
What is job costing and why does it matter for contractors?
Job costing tracks materials, labor, subcontractor payments, and equipment costs against each specific job instead of lumping them into one general expense category. It's the only way to know which jobs are actually profitable and which ones are quietly losing money, even while the business as a whole looks busy. Paired with progress billing and an accurate work-in-progress picture, it gives you a real-time view of project health instead of a surprise at year-end.
The Real Impact of Getting Your Books Right
A busy schedule and a profitable business are not the same thing, and without job-level costing there's no way to tell them apart. It's common for a contractor to have one job running well ahead of budget and another quietly bleeding money on rework, material overruns, or underestimated labor, with the two blending together into a total that looks fine on the surface. Real job costing separates them out, so you can see exactly which jobs are earning their keep and which ones need a different bid approach, a tighter scope, or a hard conversation with a supplier, before you've bid three more jobs the same way.
Cost overruns are far easier to manage while a job is still open than after it's closed out. When job costs are tracked as the work happens, a material price spike or a labor overrun shows up as a number you can react to mid-project, adjusting scope, renegotiating, or flagging it to the client, instead of a loss you only discover in the final accounting. That same current, job-level view is what makes an accurate WIP schedule possible, which matters the moment a bonding company or a lender asks for one. A WIP report built on outdated or estimated numbers can slow down financing right when you need it, while an accurate one builds the kind of credibility that makes bonding and lending conversations go smoothly.
And then there's the cash flow side, which is where a lot of contracting businesses actually get squeezed. Billing and cost timing rarely line up perfectly. Materials and labor often have to be paid before a progress bill goes out, and retainage can hold back a meaningful chunk of a payment until a job wraps entirely. Clean books that track billings against costs in real time let you see a cash crunch coming weeks before it hits, so you can plan around it instead of scrambling to cover payroll on a job that's technically profitable but hasn't paid out yet.
What We Help With
Job costing per project
Materials, labor, subcontractors, and equipment tracked against each job, so you know which ones are actually profitable.
Progress billing & WIP tracking
Billing schedules and a current work-in-progress picture that show whether a job is on track, overbilled, or falling behind.
Subcontractor 1099 tracking
Subcontractor payments recorded accurately throughout the year, so year-end 1099 filing isn't a scramble.
Equipment and vehicle expense tracking
Clear records of equipment and vehicle costs, separated out where it matters for job costing and tax purposes.
Cash flow planning around payment timing
Planning that accounts for retainage, progress billing schedules, and the gap between paying costs and getting paid.
Tax planning for seasonal, project-based income
Estimated payments and planning built around how your jobs and payments actually land through the year, not a flat assumption.

Common Questions
Frequently Asked Questions
What is job costing and why does it matter for contractors?
Job costing means tracking every cost, materials, labor, subcontractors, equipment, against a specific job instead of lumping everything into one general expense pool. Without it, you can only tell whether the business as a whole made money, not which jobs did the work and which jobs quietly ate the profit. A contractor can close out a busy year and still not know that two of their biggest jobs actually lost money once real costs were allocated correctly. Job costing gives you that visibility while there's still time to act on it, not after the job is closed out.
How does progress billing work?
Progress billing means invoicing a client for a portion of the contract as work is completed, rather than waiting until the entire job is finished to bill. It keeps cash flowing in alongside the costs you're incurring, instead of leaving you to front months of labor and materials before you see a payment. The tricky part is keeping your billing and your actual job costs aligned. If billing runs ahead of costs or vice versa, your books can make a job look more or less profitable than it actually is at any given moment, which is exactly what accurate work-in-progress tracking is meant to catch.
Do you track 1099s for subcontractors?
Yes. If your business pays subcontractors, keeping accurate records throughout the year, who was paid, how much, and for what, makes year-end 1099 filing straightforward instead of a January scramble to reconstruct a year of payments. We help set up subcontractor tracking as part of your regular bookkeeping so the information is already organized when filing season comes around.
How does seasonal or project-based income affect tax planning?
Construction income rarely arrives evenly. A big job might close out in one quarter and leave the next one quiet, or weather might shut down work for weeks at a time. Tax planning that assumes steady, even income can leave you short on an estimated payment right when cash is tightest. We plan around your actual project and payment timing so estimated taxes and other obligations line up with when the cash is actually in the bank, not an assumption that doesn't match how construction income really flows.
What is WIP and why do lenders and bonding companies ask for it?
WIP, work-in-progress, is a report that shows the status of every active job: contract value, costs incurred so far, billings to date, and estimated cost to complete. It's how you and anyone evaluating your business can see whether a job is on track, over budget, or overbilled relative to the actual progress. Lenders and bonding companies ask for it because it's one of the clearest pictures of a contracting business's real financial health, and an outdated or inaccurate WIP schedule can slow down or jeopardize financing you're counting on.
Can you help if we're already behind on job costing?
Yes, this is a common starting point. A lot of contractors come to us with materials, labor, and subcontractor costs all mixed together in one general ledger, with no way to tell which jobs were actually profitable. We can rebuild that structure going forward and, where the records allow it, reconstruct enough history to give you a clearer picture of past jobs too.
Do you work with contractors who use construction-specific software?
Yes. Whether you're on general accounting software or a construction-specific platform, we work with the data it produces and help make sure job costing, billing, and reporting are set up correctly within it. If you're not currently using a system built for job-level tracking, we can talk through whether one makes sense for your business.
