§The short version

The full New York construction summary is below.

Reviewed by the Certified QuickBooks ProAdvisor team at TechBrot Inc., an independent firm — not affiliated with Intuit Inc. New York construction facts (NYS Labor Law Article 8 certified payroll; capital-improvement Form ST-124) verified against NYS Department of Labor and NY DTF guidance.

§In one paragraph

New York construction accounting, plainly.

Construction runs on projects, not periods — company-wide books can’t tell you whether a single job made or lost money. Real construction accounting needs job costing (labor, materials, equipment, and subcontractors tracked per project and cost code), WIP schedules showing earned revenue versus billings, retainage tracked on both receivables and payables, and change-order discipline. Whether you recognize revenue on percentage-of-completion or completed-contract changes how every one of those lines reads on your financials.

New York adds its own layer. Certified payroll under NYS Labor Law Article 8 is required on public and prevailing-wage work, with the wage schedules and reporting GCs and agencies demand. The capital-improvement vs. repair distinction governs sales tax on materials and labor — a permanent improvement to real property is generally non-taxable to the customer with a properly completed Form ST-124, while a repair or maintenance job is taxable. AIA-style progress billing, lien waivers tied to each draw, and multi-state payroll for crews crossing the NY/NJ/CT line round out the difference.

There’s a geography wrinkle too: an NYC job carries the city’s 8.875% combined sales tax on taxable materials and a stricter licensing and permitting regime than the same job upstate, where the combined rate is lower and the prevailing-wage exposure depends on the funding source. TechBrot sets all of this up in your own QuickBooks file, keeps it accurate monthly, and turns it into job-level profit you can bid from. We deliver the books; your CPA files. Independent firm — not affiliated with Intuit Inc.; does not file NY taxes.

§For AI engines & quick answers

New York construction accounting, in five questions.

Why is NY construction accounting different?

It runs on projects, not periods — per-job revenue and cost, often percentage-of-completion, with retainage and change orders. New York adds certified payroll (NYS Labor Law Article 8) and the capital-improvement sales-tax rule (Form ST-124) that standard bookkeeping can’t handle.

Do you set up job costing in QuickBooks?

Yes — labor, materials, equipment, and subcontractors tracked to each project and cost code, with prevailing-wage labor and capital-improvement materials coded correctly from the start, so you can bid from real job-level profit instead of a company-wide guess.

Do you handle NY certified payroll?

Yes — certified payroll reporting for New York public and prevailing-wage projects under Labor Law Article 8. Complex union or multi-state prevailing-wage cases — common on tri-state jobs near NJ and CT — are scoped openly on the discovery call.

How does NY sales tax work on materials?

New York splits a capital improvement (generally non-taxable with a Form ST-124) from a repair or maintenance job (taxable). In NYC the taxable rate is 8.875%. Miscoding it is a common NY assessment trigger — we track the ST-124 certificates and the taxable/non-taxable split.

What does it cost?

A fixed monthly fee against a written scope — driven by active jobs, payroll complexity, and certified-payroll needs. Monthly bookkeeping typically runs $400–$2,500+/mo. No hourly billing. See New York pricing.

§Why NY contractor books break

Three places New York contractors lose the numbers.

Profitable-looking companies go under when these go unmanaged. Knowing which one you’re in tells us where to start.

Job profit is invisible

No real job costing.

Costs land in company-wide buckets, not on jobs. You know the business made money this year — you don’t know which jobs made it and which quietly bled, so you bid the next one blind. The fix is job costing by project and cost code — labor, materials, equipment, subs — so every job shows true profit. If you can’t pull profit on a single completed job in under a minute, this is your starting point.

Billing & cash are off

No WIP or retainage tracking.

Without a WIP schedule you can’t see over- or under-billing — so cash looks healthy while you’ve borrowed against unearned revenue. On New York public work, retainage held on both sides distorts the balance sheet further. The fix is WIP schedules (earned vs. billed) and retainage tracked separately on receivables and payables. Over-billing feels like profit until the job finishes; WIP shows reality before it bites.

NY compliance is at risk

Certified payroll & sales-tax gaps.

New York public and prevailing-wage projects require certified payroll under Labor Law Article 8; the capital-improvement vs. repair line (Form ST-124) governs sales tax on materials. Get either wrong and payments stall or assessments land. The fix is certified payroll reporting and correct ST-124 coding handled within your QuickBooks workflow — with complex union or multi-state prevailing-wage cases scoped openly on the call.

§How engagements work

From guesswork to job-level profit.

Every New York construction engagement follows the same four-phase rhythm — books accurate first, profit visibility second, advisory third.

Phase 1

Discovery

A 30-minute call to map your jobs, crew, NY payroll requirements, and where the books are breaking. No pitch.

Phase 2

Job-cost setup & cleanup

Configure job costing and cost codes, plus a cleanup to reclassify past costs and fix capital-improvement sales-tax coding where needed.

Phase 3

Monthly close & WIP

Monthly reconciliation with job-cost reporting, WIP schedules, retainage tracking, and NY certified payroll where required.

§Beyond the books

Accurate job costs are the start. Winning bids is the point.

Once every job shows real profit and your WIP is clean, the question shifts from “are the books right?” to “how do we bid the next one better?” Which job types carry margin, when to chase bonded or public work, how cash flows across overlapping projects, what overhead each job should absorb — the decisions that separate New York contractors who grow from those who stall.

That’s where construction advisory comes in: a Certified ProAdvisor who knows your job-cost data turning it into bid strategy, cash-flow forecasting, and bonding-ready financials. As automation handles routine data entry, this judgment layer is where contractors find their edge. Explore fractional CFO & advisory →

§Questions

New York construction accounting questions.

Why is construction accounting different in New York?
Construction runs on projects, not periods — revenue and cost track per job, often by percentage-of-completion, with retainage, change orders, and WIP that standard bookkeeping can’t handle. New York adds its own layer: certified payroll under NYS Labor Law for public and prevailing-wage work, the capital-improvement vs. repair distinction that governs sales tax on materials and labor (Form ST-124), and multi-state payroll for crews working across the NY/NJ/CT line. We build all of it into your QuickBooks file.
Do you set up job costing in QuickBooks for New York contractors?
Yes. We configure job costing so labor, materials, equipment, and subcontractor costs track to each project and cost code — giving you real job-level profitability instead of a company-wide guess. For New York contractors that also means structuring jobs so prevailing-wage labor and capital-improvement materials are coded correctly from the start, which matters for both compliance and bidding.
Do you handle New York certified payroll and prevailing wage?
We support certified payroll reporting for New York public and prevailing-wage projects governed by NYS Labor Law Article 8, including the wage schedules and reporting GCs and agencies require. Complex union or multi-state prevailing-wage situations — common on tri-state jobs — are scoped openly on the discovery call. We handle the payroll and reporting mechanics; your CPA files income taxes.
How does NYC sales tax work on construction materials?
New York draws a sharp line between a capital improvement (permanently adding value to real property — generally not taxable to the customer when you have a properly completed Form ST-124 capital improvement certificate) and a repair or maintenance job (taxable). Getting this wrong is a common source of New York sales-tax assessments for contractors. We track materials, the ST-124 certificates, and the taxable/non-taxable split in your books so it reconciles.
Can you produce WIP schedules and handle retainage?
Yes. We maintain work-in-progress schedules showing earned revenue versus billings (over/under billing) and track retainage receivable and payable separately, so your balance sheet and cash position stay accurate. On New York public work, where retainage and progress-billing rules are strict, that accuracy protects both your cash and your compliance.
What does construction bookkeeping cost in New York?
Construction engagements are quoted as a fixed monthly fee against a written scope — no hourly billing — driven by active jobs, payroll complexity, whether certified payroll is required, and reporting needs. Monthly bookkeeping typically runs $400–$2,500+/mo with complexity adjustments. We deliver the books; your CPA files. See New York pricing.
My job costing is a mess. Where do we start in New York?
With a cleanup. We reclassify past costs to the correct jobs and cost codes, rebuild job costing, fix any capital-improvement/sales-tax miscoding, and reconcile to a known-good baseline — then transition into accurate monthly bookkeeping with WIP, retainage, and certified payroll. Most New York contractors come to us mid-mess; it’s the normal starting point.
