Job costing and lien discipline for a business made of small jobs
Nobody in Mount Vernon goes broke on the big job. They go broke on the forty small ones. This is a dense pre-war city on the Bronx line, and the work is boiler swaps, roofs, violations, water services and apartment turnovers, priced in thousands and run several at a time by the same three trucks. A WIP schedule tells you almost nothing about that business. What decides it is whether the extra got written down, whether the invoice went out, and whether anyone recorded your last day on site, because New York starts the lien clock from that date on every job separately.
On the ground
Downtown Mount Vernon, New York
A high volume of small contracts is a different accounting problem from a small number of large ones, and almost every piece of construction accounting advice you will read online was written for the second kind of company.
They didn’t just record transactions and call it a day. They built a custom chart of accounts around how a remodeling company actually runs, did a full catch-up on years of bookkeeping inside QuickBooks Online, and now stay on top of my monthly bookkeeping and payroll. Every step, they broke it down in simple terms instead of burying me in accountant talk.
FinTruction rebuilt the whole thing from the ground up, with real job costing, work in progress, and retainage. They didn’t just hand me reports and disappear; they walked me through my numbers until I understood them.
Sahil and his team handle the bookkeeping and job costing for my painting business. They cleaned up my books and set up integrations that give me accurate, timely job costing with solid weekly data. Reliable, detailed, and genuinely invested in getting the numbers right.
FinTruction is the only bookkeeping team we’ve found that truly understands construction accounting and WIP reporting. They aligned our income and costs across 21 jobs and gave us full, monthly transparency. Fast, accurate, and an indispensable partner.
When I came to FinTruction I had no financial structure. No job costing, no WIP tracking, books behind. They did a full cleanup and rebuilt job costing and WIP tracking in QuickBooks. Now I know what’s billed, what’s owed, and where every job stands.
A couple of minutes from a contractor we support, sharing what working with FinTruction has been like and what changed once their numbers finally made sense.
Most contractors here stopped opening jobs years ago because the paperwork felt disproportionate to a four thousand dollar boiler. The result is a profit and loss statement that tells you the company made money and nothing at all about which of the two hundred things you did last year were worth doing again.
Every construction platform claims to have a "QuickBooks integration." Most break the moment your books need to be accurate. Sales tax mismaps, retainage disappears, change orders create duplicates, and job costing reports stop matching project reality. We fix the integration so your software, your books, and your job‑level numbers all tell the same story.

On repair work the money is lost between the last day on site and the invoice going out. Somebody finishes, moves to the next address, and the paperwork waits for a quiet evening that never comes. Six weeks later the customer disputes an extra nobody wrote down, and the date the clock started is already fuzzy.
New York treats a capital improvement and a repair completely differently, and in a city where most of the work is repair the exposure usually runs toward undercollected tax rather than overpaid tax. The determination has to be made per contract and substantiated at the time, not defended years later from a stack of invoices.
Working on pre-war stock carries a standing cost base that new construction does not: lead-safe certification and training, containment and cleanup, asbestos survey and abatement coordination, unforeseen conditions once a wall is open, and the hours spent waiting on an inspector. Buried in overhead, all of it makes your small jobs look better than they are.
A repair business fails from cash, not from margin. Our controller services and CFO services answer the questions that decide whether you survive a slow quarter: how much of your money is sitting with payers who cannot pay quickly, what a truck or a second crew actually costs you, and how much work you can carry before the float runs out.
A general bookkeeper can record transactions. Construction accounting is a different job.

Mount Vernon is a little over four square miles of city with roughly sixteen thousand eight hundred people in each of them at the 2020 census, which makes it one of the most densely populated places in New York State outside the five boroughs. It runs right up against the Eastchester and Wakefield sections of the Bronx along its southern edge. It was substantially built out generations ago, and the building stock reflects that: brick apartment blocks, two and three family houses, storefronts with apartments over them, schools and institutional buildings that predate the war, and the water, sewer and street infrastructure that went in underneath all of it at the same time.
So the work here is not what construction marketing assumes construction work is. There is very little greenfield. There is an enormous amount of replacing, repairing, opening up, correcting and turning over. A busy Mount Vernon contractor is not managing three projects, they are managing thirty five open tickets, most of which will be finished and invoiced inside a month, several of which will run over because of what was found behind the wall, and a few of which will quietly never get billed at all.
The customers are the second half of the story. A large share of the private work is bought by small landlords and owner-occupiers who are paying out of a rent roll or a savings account, not a construction loan. They are not slow because they are difficult, they are slow because the money is genuinely tight, and a surprise on your job is a surprise in their household. On the public side the city has had a long and public struggle with its own financial administration, to the point where Moody's withdrew its credit rating in 2019 after audited financial statements were not provided. Municipal water, sewer and street work is a real and continuing part of this market, and it is also work where you will be financing your customer for a while.
One honest note about geography. Mount Vernon is inside the New York City metropolitan area and the Bronx begins at the end of some of these streets, so plenty of contractors here work on both sides of the line and some of what you read about the city applies. If a meaningful share of your work is physically performed in the five boroughs, read our page on construction accounting in New York City, because the city tax and permitting picture is genuinely different. But if your trucks mostly stay in Westchester, the NYC playbook is not your playbook, and running your books to it will cost you attention you need elsewhere.
A notice of lien may be filed at any time during the progress of the work and the furnishing of the materials, or within eight months after completion of the contract or the final performance of the work and the final furnishing of the materials. Where the improvement is to real property improved or to be improved with a single family dwelling, that period is four months rather than eight. Mount Vernon has a lot of one and two family housing, so both clocks run in the same company in the same week. We are not attorneys and we do not file notices. We keep the last date on site recorded against each job so nobody is reconstructing it from a text message.
New York's prompt payment rules for private construction apply to a construction contract where the aggregate cost of the project, including all labor, services, materials and equipment to be furnished, equals or exceeds one hundred fifty thousand dollars. The article also excludes public work and several residential categories, among them an individual one, two or three family residential dwelling and residential projects of four thousand five hundred square feet or less. Most Mount Vernon repair contracts sit outside it. That is worth knowing before you rely on it, because it means your written terms and your documentation are doing all the work that a statute is doing for a contractor across town on a tower.
In New York a capital improvement to real property is not subject to sales tax on the labor, while repair, maintenance and installation services to real property are taxable. Form ST-124, the certificate of capital improvement, is the substantiation, and the customer has to give it to you within ninety days after the service is rendered. A properly completed certificate accepted in good faith shifts the burden of proving the transaction was taxable onto the customer. In a market this repair heavy, the common error is not aggressive tax planning, it is a habit of treating everything as exempt on jobs that were never capital improvements at all. Westchester also has more than one local rate in play, so confirm the combined rate for the jurisdiction the job sits in.
The federal Renovation, Repair and Painting program covers homes, childcare facilities and preschools built before 1978, and requires that anyone paid to perform work that disturbs painted surfaces in those buildings be certified, with employees trained. In a city built out well before that date this is not an edge case, it is the default condition of the work. The accounting point is that certification, training, containment and cleanup are recurring costs of being allowed to do this work at all, and they belong in your pricing and your job costs rather than in a general overhead account nobody reads.
Money received on a New York construction contract is a trust asset held for the beneficiaries of that job, and section 75 requires the trustee to keep books or records for each trust, including a record showing the allocation to each trust where several trusts share one bank account. Failing to keep them is presumptive evidence that trust funds were applied outside the trust. For a company running thirty jobs through one operating account, that allocation record is the entire defense, and it cannot be built retrospectively with any credibility.
Municipal and agency-funded infrastructure and housing work carries wage, reporting and documentation conditions written into the contract and the funding agreement rather than into a single statute, and prevailing wage and certified payroll obligations can attach depending on how the job is funded. Read the contract and the funding source before you price it, and set the job up to produce what it asks for from week one. Retrofitting compliance onto a job already underway is where the margin goes.
We support the trades that keep an older city standing, from the mechanical and plumbing firms who live on emergency calls to the small general contractors turning over apartments building by building.
Running a Construction Company in Mount Vernon?
Get Your Free AuditA fair question if you already have a bookkeeper, or a cousin who does the return every April. Here is the honest answer.
Contractors who were behind, off the bank, or heading into an audit. Same work, different trades.
Built From Scratch
"FinTruction set the accounts up properly first, then cleaned up everything I never entered."
Rescue + Monthly
"They built a custom chart of accounts around how a remodeling company actually runs."
Most Mount Vernon contractors do not need another subscription. They need the file they already pay for configured so that a small job can be opened, costed and billed without it feeling like a project.
The QuickBooks files we inherit here were usually set up by someone who assumed you sell products. Customers exist, jobs do not, everything lands in one income account, and there is no way to ask the file which kind of work pays and which kind you have been subsidising for years.
Is your QuickBooks file hiding your best work?
If your crews are already logging calls, hours and materials on a phone, that data should reach the accounting without anyone retyping it. The office should be checking numbers, not creating them a second time from a pile of paper on Friday afternoon.
One set of numbers that the field and the office both believe.
Once the systems talk to each other, the monthly reporting stops being a history lesson and starts being a list of decisions. These are the numbers Mount Vernon contractors use to decide what to chase and what to stop taking:

More than a contractor running three large jobs does, actually. On a large contract the money is visible: one budget, one billing schedule, one owner calling every week. On forty small jobs the money is invisible by design. Nobody notices that the boiler swap on South Fulton ran two extra days, or that the roof on Gramatan absorbed a dumpster nobody billed, because each individual leak is too small to argue about. Add them up over a year and they are the whole difference between a good year and a flat one. Job costing on small work is not about precision, it is about being able to see a pattern at all.
Lien Law section 10 lets you file at any time during the progress of the work, or within eight months after completion of the contract or the last item of work performed and materials furnished. Where the improvement is to real property improved or to be improved with a single family dwelling, the period is four months rather than eight. In Mount Vernon that difference is not academic, because plenty of your work is on one and two family houses. We are not attorneys and we do not file notices. What we do is keep the last date on site recorded per job, so your attorney is working off a real date rather than a foreman's memory.
On most Mount Vernon repair work, no, and that surprises people. General Business Law article 35-E applies to a construction contract where the aggregate cost of the project, including all labor, services, materials and equipment, equals or exceeds one hundred fifty thousand dollars. It also carves out public work and a list of residential situations, including an individual one, two or three family dwelling and residential projects of four thousand five hundred square feet or less. A great deal of the work in this city falls outside it on both counts. That means the statutory clock is not going to rescue you. Your contract terms, your invoicing discipline and your lien rights are the leverage you actually have.
In a repair driven market the risk runs the opposite way from a new construction market. A capital improvement to real property is not subject to sales tax on the labor. Repair, maintenance and installation services are taxable. Contractors who came up doing rehab often carry a habit of treating everything as a capital improvement, and in Mount Vernon most of the work genuinely is not one. The substantiation is Form ST-124, the certificate of capital improvement, which the customer gives you and which has to be obtained within ninety days of the service being rendered. Obtained at job setup it is routine paperwork. Chased later it usually cannot be obtained at all.
It puts a permanent compliance cost inside jobs that are priced like simple ones. The federal Renovation, Repair and Painting rule covers homes, childcare facilities and preschools built before 1978, and requires that anyone paid to perform work disturbing painted surfaces be certified, with their employees trained. Mount Vernon is almost entirely pre-1978 stock, so that is not an occasional job type, it is your whole market. Firm certification, renovator training, containment materials and the extra hours all cost money. Most files we inherit bury them in overhead, which quietly makes every small job look more profitable than it is and every price look more competitive than it should be.
Funds you receive on a New York construction contract are trust assets, held for the people who worked on and supplied that job. Section 75 requires the trustee to keep books or records for each trust, including a record showing the allocation to each trust where several share one bank account. Failure to keep them is presumptive evidence that trust funds were applied outside the trust. That is an unusually direct line from bookkeeping quality to personal exposure. The classic small contractor failure is paying last month's supplier out of this month's deposit, which is exactly the pattern the rule exists to catch. We treat the trust record as a monthly close item rather than something to reconstruct under pressure.
It cannot make a municipality pay faster, and anyone who tells you otherwise is selling something. What it can do is stop the slow payer from taking the rest of your company down with it. That means knowing, at any moment, how much of your receivable balance sits with one payer and how old it is, what you have already spent against work you have not been paid for, and what the cash position looks like if that money arrives ninety days later than promised. Mount Vernon has had public difficulty with its own financial reporting, including Moody's withdrawing its credit rating in 2019 after audited financial statements were not provided. Plan around the payer you actually have.
Yes, and it is worth settling before it becomes a filing problem. New York City imposes an unincorporated business tax on income earned from business carried on in the city, which reaches partnerships and sole proprietorships, and city work brings its own permitting, insurance and wage rules that Westchester work does not. That is a different set of problems from the ones on this page, and we cover them on our page for construction accounting in New York City. The accounting requirement is simple and unglamorous: your jobs have to be tagged by where the work was physically performed, from the first day, because allocating income by location later is guesswork.
