Job costing, WIP and certified payroll that survives a public works audit
In Oakland and across the East Bay, the compliance is the job. Port and transit contracts, county work, school bonds and affordable housing all arrive with prevailing wage, DIR registration, certified payroll and apprenticeship paperwork attached, and every one of those obligations is really an accounting task. Meanwhile retention sits for months and the draw package the lender wants looks nothing like the invoice you sent. We keep certified payroll and job cost coming out of the same numbers so they cannot disagree, track retention by contract instead of burying it in receivables, and give you a monthly WIP that shows where you are overbilled before anyone else notices.
On the ground
Downtown Oakland, California
A large share of East Bay work is public or publicly funded, which means the compliance obligations and the accounting are the same problem. Generic bookkeeping cannot produce what these contracts ask for.
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.
Oakland is a public works market with a housing market on top of it. The Port of Oakland is one of the busiest container ports on the West Coast, and terminal, wharf, rail and landside work around it keeps marine and heavy civil contractors busy on contracts that almost always carry federal or state funding. Regional transit adds another steady stream, and Alameda County, the city and the school districts generate a continuous pipeline of bond-funded building.
Housing is the other half. The East Bay has a serious affordability problem and a correspondingly serious pipeline of affordable and mixed-income development, most of it stacked from several public and quasi-public funding sources. Oakland also has a large stock of older buildings and a soft-story retrofit program, which keeps retrofit and renovation contractors working on projects where the scope genuinely changes once the walls are open.
What ties it together is documentation. Very little East Bay work is a simple private contract where you invoice and get paid. Most of it involves a wage determination, a certified payroll filing, an apprenticeship obligation, a draw package, retention held to a statutory limit, and an agency that can ask for backup a year later. Contractors here are not usually failing because they cannot build. They are failing because the office cannot keep up with what the contract requires.
That is a solvable problem, but not with a bookkeeper who treats a construction company like any other small business. It needs job costing, payroll and compliance reporting designed as one system rather than three.
On California public works the certified payroll you file and the labor cost in your job report have to be the same numbers. When payroll, compliance filing and job costing are done in three different places by three different people, they drift, and the drift is what an audit finds. We run all three from one process.
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.

Public work is documented work. The cost structure has to satisfy the contract, the funding agency and your own need to know whether the job is making money, and those are not automatically the same thing. We build cost codes that answer all three, then keep labor, burden, materials, equipment and subcontractor costs posted weekly.
Affordable and mixed-income housing runs on draws, and the package the lender or agency wants rarely matches the invoice you would otherwise send. If the underlying records are not organized for it, every draw becomes a manual assembly job that delays the money. We structure the job cost so the draw package is produced from the records.
Long public contracts are where underbillings hide, and an underbilling is money you have already spent and not yet asked for. We prepare a monthly work in progress schedule that compares cost to date against the current estimate, calculates earned revenue on percentage of completion, and shows over and underbilling by job.
California is an expensive place to carry a job. Labor, insurance and the working capital tied up in retention all mean the decision to take a larger contract is a financial one first. Our controller services and CFO services cover what you can carry and what a job will do to cash before it pays.
We support contractors across the East Bay, from marine and civil crews working the port to housing and retrofit contractors rebuilding Oakland block by block.

California contractors are licensed by the Contractors State License Board, and licensure comes with a contractor's bond, workers' compensation obligations, and classification limits on the work you may perform. Licensing, bond and insurance costs are real costs of doing business and belong in your overhead rate rather than sitting as unclassified expenses, otherwise every bid you produce is quietly understating what the job needs to carry.
Most California public works require contractors and subcontractors to be registered with the Department of Industrial Relations, to pay the applicable prevailing wage determination for the craft and county, and to submit certified payroll records electronically. Apprenticeship requirements add contract award and request documentation plus ratio obligations. This is the single largest compliance load on East Bay contractors, and it is administered out of payroll and job cost, which is why we treat it as an accounting function rather than paperwork.
California limits retention on most public works prime contracts to five percent, with rules governing how retention passes down to subcontractors and when it must be released after completion. That is comparatively contractor-friendly, but only if you track it. Retention buried inside accounts receivable is retention nobody is chasing, and it also misrepresents your balance sheet to a surety reading it carefully.
California distinguishes between materials and fixtures in construction contracts. A contractor is generally the consumer of the materials it furnishes and installs, paying tax on purchase, while for fixtures the contractor is generally treated as the retailer, with tax applying to the fixture price. Most contractors never make the distinction in their records, which creates both overpayment and audit exposure. We make the split visible at the job level.
California gives contractors and suppliers lien rights on private work and stop payment notice rights on public work, each with its own preliminary notice and deadline requirements. We are not attorneys and we do not file notices. What we do is keep unpaid amounts organized by job, tier and date furnished so the deadline calendar runs off real data and your attorney has the backup immediately.
Oakland attaches its own conditions to city-funded construction, and local hire, apprenticeship and reporting commitments are common on public projects here. These obligations have a cost, and that cost belongs on the job it was incurred for. We tag the compliance effort to the project rather than letting it disappear into general administration.
A fair question if you already have a bookkeeper or a payroll service. 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 Oakland contractors do not need new software. They need what they already pay for configured for construction and connected to the accounting, so compliance reporting is a by-product rather than a second job.
Most QuickBooks files we inherit were configured for a business that sells products. For a contractor that means jobs are customers, cost codes do not exist, retention hides inside receivables, and payroll cannot produce a certified payroll report without manual rework every week.
Is your QuickBooks file working against you?
If your project managers already track budgets, commitments and change orders in a construction platform, the office should not be typing it again. We connect the field system to the accounting so the numbers agree and the month does not open with an argument about whose figure is right.
One set of numbers that the field and the office both believe.
Once the systems are connected, reporting stops being a history lesson. These are the reports East Bay contractors use to decide what to chase and what to walk away from:

Because so much East Bay work is public or publicly funded, and that carries a compliance load a general bookkeeper is not set up for. Port terminal work, BART and transit contracts, county and city projects, school bonds and affordable housing all bring prevailing wage, DIR registration, certified payroll and apprenticeship obligations. Every one of those is an accounting task before it is an administrative one, because the numbers have to come out of payroll and job cost. Add retention held for months and it becomes very easy to be busy, compliant and still short of cash.
On most California public works you have to be registered with the Department of Industrial Relations to bid or perform the work, pay the prevailing wage determination for the craft and county, and file certified payroll records electronically. Apprenticeship obligations apply as well, with contract award and request forms to submit and ratio requirements to meet. The practical accounting problem is that the certified payroll you file and the labor cost sitting in your job cost report have to be the same numbers. We produce both from one payroll process so they cannot drift apart, which is what turns a routine audit into a problem.
California draws a distinction most contractors do not track properly. Under state rules a contractor is generally treated as the consumer of the materials it furnishes and installs, so tax is paid on the purchase. Fixtures work differently, with the contractor generally treated as the retailer, and tax applying to the fixture price. Getting the materials and fixtures split wrong is a quiet and recurring margin leak, and it is exactly the sort of thing nobody notices until an audit. We set purchasing and job cost up so the distinction is visible on the job rather than reconstructed later.
On most California public works, retention on the prime contract is limited by statute to five percent, and there are rules about how retention flows down to subcontractors and when it must be released after completion. That is more favorable than many states, but only if you actually track it. We keep retention receivable and payable separate from ordinary receivables and payables, by contract, with release conditions and an aging, so you know what is owed, from whom, and whether the release condition has already been met.
Yes, and they need careful handling. Affordable and mixed-income housing in Oakland is typically stacked from several funding sources, and public money brings prevailing wage and reporting obligations even when the developer is private. Draw schedules are tied to lender and agency requirements rather than to your billing cycle, and documentation is requested at a level of detail most contractors are not keeping. We structure job costing so a draw package can be produced from the records rather than assembled from scratch each month.
Yes. Oakland has a soft-story retrofit program and a large stock of older buildings, so retrofit and renovation is steady work in the East Bay. It is also work where the scope genuinely changes once the walls are open, which means change orders, unforeseen conditions and time and materials sections running alongside a fixed-price base contract. We track the base contract, approved changes and unpriced work as separate visible numbers, so you can see how much of the job is being performed on the promise of a change order that has not been signed yet.
The Bay Area has a strong union presence, and fringe benefits run to several trust funds at different rates, each with its own monthly remittance format and its own audit. Fringes are part of the cost of labor and belong on the job, not in a general payroll account, otherwise your job cost understates what the work really cost you. We allocate fringes to the job alongside base wages and keep the remittance reporting reconciled to the payroll records a fund auditor will ask to see.
We work with contractors across Alameda and Contra Costa counties and the wider Bay Area, including Oakland, Berkeley, Alameda, Emeryville, San Leandro, Hayward, Fremont, Richmond, Concord, Walnut Creek and Pleasanton. Our work is fully remote, so you get construction-specific accounting without paying for an office you do not need.
Yes, and it usually works better that way. Most contractors have a CPA who prepares the return and perhaps a review, but who is not in the file month to month. We keep the books, the job costing and the WIP schedule in a state your CPA can work from directly, which shortens their work and reduces what they have to ask you for. Sahil Ahmad, CPA reviews our side of it.
