New York · Construction Accounting

New York construction accounting that knows which job made money.

Under New York Lien Law Article 3-A, the money a contractor receives for an improvement of real property is trust money (§70), and every trustee must keep books or records for each trust (§75). We keep each job’s receipts and payments traceable to it, set up real job costing, WIP, and retainage, handle NY certified payroll under NYS Labor Law Article 8, and code the capital-improvement vs. repair sales-tax line (Form ST-124) — all in your own QuickBooks file, by your TechBrot team, with every close reviewed by a Certified QuickBooks ProAdvisor.

If your file needs our paid diagnostic first, its fee is credited in full against the cleanup. Either way, you get a fixed fee in writing before any work starts.

§The short version

New York construction accounting from TechBrot tracks each job, not just the period: job costing by project and cost code, WIP schedules of earned revenue against billings, retainage on both sides, NY certified payroll and capital-improvement sales-tax coding with Form ST-124. Monthly bookkeeping runs $500–$2,500+/mo, in your own QuickBooks file.

§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 QuickBooks 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.
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 $500–$2,500+/mo with complexity adjustments. See TechBrot 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. Starting mid-mess is fine: the cleanup is built for it.
