Job costing, WIP and bonding-ready books for big tilt-up and site work
In the Inland Empire one contract can be most of your year. A tilt-up distribution center or a mass grading package burns cash for months before the first pay application clears, and retention sits on top of that. Construction accounting in Riverside has to survive that concentration: miss the estimate to complete on a job that size and the WIP does not nudge, it swings the whole company. We cost every code weekly, keep uninstalled materials from inflating percentage of completion, hold retention off the receivables aging, and hand your surety a statement that supports the next single-job limit.
On the ground
Spanish Revival landmark, downtown Riverside
A big industrial job is not one job, it is a sequence: over-excavation and recompaction, underground wet and dry utilities, slab, panel casting, erection, steel and deck, roofing, fire protection. Costed as a single bucket it tells you nothing until it is finished. Job costing for Riverside contractors starts with cost codes that follow that sequence, so you can see which phase is eating the contingency while the crane is still on site. It runs on top of clean construction bookkeeping, because a cost report is only as good as the coding underneath it.
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.
Also work with Foundation, Sage 100, Bill.com, ADP, Gusto, Ramp, and more. See all platforms we integrate →
Concentration makes the work in progress schedule the most important report you own. We prepare it monthly against a re-forecast cost to complete, calculate earned revenue on percentage of completion, and show over and underbilling by job and in total, with the dominant contract broken out so it cannot hide the rest of the company or be hidden by it.
On a large Inland Empire package you fund weeks of concrete, steel and subcontractor cost before a pay application is even reviewed, then wait out approval terms and lose another slice to retention. That gap is the single most common reason a busy contractor here runs out of money. We bill it accurately and on time, and we forecast the gap before you sign.
For most growing contractors in this market the constraint on the next job is the bond, not the crew. Sureties underwrite working capital, equity, the credibility of your WIP and how much of your backlog sits with a single owner. We produce statements in that form and tell you in advance what a machine purchase or a new award does to the numbers an underwriter reads.
The riskiest decision an Inland Empire contractor makes is accepting a contract larger than the last one from a developer who already owes them money. Our controller services and CFO services put a number on that before you commit: what the job does to cash, what happens if payment slows by thirty days, and what you can carry.
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.
Riverside anchors the Inland Empire, and the Inland Empire is where the West Coast keeps its goods. Land was cheaper here than anywhere within reach of the ports, so the region filled with distribution centers, fulfilment buildings and cold storage at a scale that has few parallels in the country. That is a specific kind of construction: mass grading and import or export of dirt, deep underground utilities, a slab that doubles as a casting bed, tilt-up panels, steel and deck, acres of single-ply roofing and an electrical service sized for automation. Solar and storage now ride on top of most of it.
The second engine is housing. Families priced out of Orange County and Los Angeles kept moving east, and Eastvale, Menifee, Beaumont, Jurupa Valley and the Temecula valley absorbed the demand. Public work fills the gaps: Riverside County and city projects, water and flood control, freeway interchange and corridor work, school bonds, and university and hospital expansion in the city itself. The trade mix that results skews heavily toward concrete, earthwork, steel, roofing and electrical, and it operates at genuine scale.
What that scale does to a contractor is concentration. A single industrial package can be worth more than everything else you have open. The schedule is milestone-driven and unforgiving, so material has to be bought early and in quantity, which means enormous cash out the door long before a pay application is approved. Then five percent or more is held back. A contractor who is winning the work can still be one slow developer away from missing payroll, and the numbers that would have warned them were sitting in a job cost report nobody produced on time.
The other half of the trap is growth. Bonding capacity, not capability, decides whether you can bid the next building, and capacity is calculated from working capital, equity and a work in progress schedule an underwriter believes. Contractors who bought equipment with cash and never adjusted their WIP find out about that at exactly the wrong moment. Fixing it is an accounting job, and it has to be done before the bid, not after. If you are not sure where your own numbers sit, our guide to work in progress reporting for contractors shows what an underwriter is actually reading.
A construction accountant working this market therefore needs to understand tilt-up sequencing, earthwork production rates and how a Riverside County prevailing wage determination lands in a payroll register, not just debits and credits. FinTruction works only with contractors, across the Inland Empire and the rest of construction accounting in California, from Riverside and Moreno Valley out to Corona, Perris, Menifee and Temecula.
The Inland Empire builds big and builds fast. When a single industrial or site package carries most of the year, the accounting has to keep up with the volume of the work and the velocity of the schedule at the same time.
CSLB Licensing and the Contractor Bond: California licenses contractors through the Contractors State License Board, and Business and Professions Code section 7048 exempts only minor work valued under $500, so effectively every commercial job in Riverside requires a license. Class A covers general engineering, Class B general building, and the Class C specialties cover trades such as C-8 concrete, C-10 electrical, C-12 earthwork and paving and C-39 roofing. Licensure also requires a $25,000 contractor bond and a qualifying individual. Those licensing, bond and insurance costs belong in a calculated overhead rate; parked in unclassified expense they make every bid understate what the job must carry.
DIR Registration, Prevailing Wage and Certified Payroll: Public work in Riverside County requires registration with the California Department of Industrial Relations under Labor Code section 1725.5, payment of the prevailing wage determination published for the craft and for Riverside County, and certified payroll records kept and furnished under Labor Code section 1776, filed electronically through the DIR eCPR system. Apprenticeship obligations add form DAS 140 for contract award information and form DAS 142 to request dispatch, plus ratio requirements, and larger public projects can carry skilled and trained workforce commitments. FinTruction generates the certified payroll filing and the job labor cost from one payroll run so an auditor finds them agreeing.
Retention on Public and Private Work: Public Contract Code section 7201 caps retention proceeds on most California public works contracts at five percent, subject to a narrow substantially complex project exception, and Public Contract Code section 7107 sets the timing for releasing retention after completion. Private developer contracts on Inland Empire industrial and tract residential work carry no equivalent cap, and larger amounts held for longer are routine. Retention hidden inside accounts receivable is retention nobody is chasing, and it overstates collectible receivables on a balance sheet a surety is reading closely. FinTruction keeps it separate, by contract, with the release condition recorded.
Sales, Use and District Tax on Materials and Fixtures: California Department of Tax and Fee Administration Regulation 1521 treats a construction contractor as the consumer of the materials it furnishes and installs, with tax paid on the purchase price, while for fixtures the contractor is generally the retailer and tax applies to the fixture price. District tax rates differ between cities across Riverside County, and materials or equipment brought in from out of state carry California use tax. On a distribution center that consumes concrete, rebar and roofing membrane by the truckload this is not a rounding error, so we make the treatment visible in purchasing and job cost rather than reconstructing it during a CDTFA audit.
Storm Water, Grading and Environmental Costs: Construction sites disturbing one acre or more of soil generally require coverage under the State Water Resources Control Board Construction General Permit, which brings a storm water pollution prevention plan prepared by a qualified SWPPP developer, ongoing inspection by a qualified SWPPP practitioner, sampling and reporting. Large Inland Empire projects also carry California Environmental Quality Act review, mitigation obligations and development impact fees. Each of those has a cost and each belongs on the job that incurred it. Booked to general overhead instead, they make earthwork look more profitable than it is and push the next grading bid too low.
Cal/OSHA Heat Illness Prevention and Summer Productivity: Title 8 of the California Code of Regulations, section 3395, requires access to shade, drinking water and cool-down rest for outdoor workers, with high-heat procedures applying on construction sites once the temperature reaches ninety-five degrees. The compliance itself is straightforward. The accounting consequence is not, because summer placement and grading in Riverside simply produce fewer units per crew hour, so a labor rate derived from spring work will overrun a July slab pour. FinTruction tracks productivity by cost code and by period so estimating uses the rate the work genuinely earns in this climate.
Preliminary Notices, Mechanics Liens and Stop Payment Notices: California preserves lien rights on private work and stop payment notice rights on public work through the preliminary notice required by Civil Code section 8200, generally served within twenty days of first furnishing labor or materials. FinTruction is not a law firm and does not file notices or liens. What we do is keep unpaid amounts organized by job, by tier and by date first furnished, so the deadline calendar your attorney or lien service runs is driven by real accounting records and the backup goes out the same day rather than after a week of reconstruction.
A general bookkeeper can record transactions. Construction accounting is a different job.
| What you need | Generic local bookkeeper | FinTruction |
|---|---|---|
| Job-level costing | Lumps all jobs into one P&L | Cost codes and margin per project |
| WIP & revenue recognition | Cash-basis, no WIP schedule | Monthly WIP with over/underbilling |
| Retainage tracking | Buried in AR/AP, often missed | Tracked receivable & payable by contract |
| Bonding & lender packages | Not equipped to produce them | Bonding-ready statements and backlog |
| Construction software | QuickBooks set up like a retail shop | QuickBooks + integrations tuned for contractors |
We support contractors across Riverside County and the wider Inland Empire, from grading and concrete crews on industrial pads to builders working the tract housing pushing east.
Running a Construction Company in the Inland Empire?
Get Your Free AuditA fair question if you already have a bookkeeper, a payroll service and a CPA who does the return. 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 Inland Empire contractors do not need another platform. They need the one they already pay for configured for construction and wired to the accounting, so the job cost report is a by-product of the work instead of a monthly rebuild.
Most files we inherit were set up for a business that sells products. In a contractor file that shows up fast: jobs entered as customers, no cost code structure, retention mixed into receivables, committed costs invisible, and equipment cost sitting in overhead where no job ever sees it.
Is your QuickBooks file working against you?
On a large industrial job the project team is already tracking budgets, commitments and change orders in a platform. The office should not be retyping any of it. We connect the field system to the accounting so the committed cost in the project tool and the committed cost in the books are the same figure.
One set of numbers the field and the office both believe.
Once the systems talk to each other, reporting stops being a history lesson. These are the reports Inland Empire contractors use to decide what to chase, what to price higher and what to walk away from:
See what this looks like in practice in our construction accounting case studies.
Because Inland Empire work concentrates revenue into very few contracts. A Riverside contractor can have four jobs open where one distribution center, mass grading package or solar site is sixty percent or more of annual volume. Under that concentration a one percent estimating error on the big job can exceed the entire margin on everything else, one slow-paying developer can stop payroll, and a surety reads the financial statement as a bet on a single contract. General bookkeeping records transactions after the fact. Construction accounting reports what the dominant job is doing while there is still time to act on it.
Run the work in progress schedule off a re-forecast estimate to complete rather than off cost to date. Cost to date only tells you what has been spent; the estimate to complete is what determines whether the contract still earns its bid margin. FinTruction rebuilds that forecast monthly with the project manager, code by code, then reports the dominant contract on its own line alongside the rest of the company, because a healthy backlog can conceal one large job going backwards. Every movement in gross margin is explained in writing, so margin fade becomes a decision point instead of a year-end surprise.
Generally no, not when they are significant relative to the contract. Under ASC 606 a contractor using a cost-to-cost input method adjusts the measure of progress for uninstalled materials, recognizing revenue on them at zero margin until they are installed. This matters on tilt-up and industrial work in Riverside because rebar, structural steel and single-ply roofing membrane are bought in bulk and staged on site. Counted as incurred cost, they make the job look further along than it is, so profit gets recognized early and fades later. FinTruction builds that adjustment into the WIP schedule.
Yes. Contractors and subcontractors on most California public works must register with the Department of Industrial Relations under Labor Code section 1725.5, pay the prevailing wage determination published for the craft and for Riverside County, and keep and submit certified payroll records under Labor Code section 1776, filed electronically through the DIR eCPR system. Apprenticeship obligations add form DAS 140 for contract award information and form DAS 142 to request dispatch, plus ratio requirements, and some larger public projects carry skilled and trained workforce commitments. The certified payroll filed and the labor cost posted to the job must be the same numbers.
Five percent is the statutory cap on most California public works. Public Contract Code section 7201 limits retention proceeds withheld on public works contracts to five percent, with a narrow exception where a project is found to be substantially complex, and Public Contract Code section 7107 governs the timing of retention release after completion. Private developer contracts on Inland Empire industrial and residential work carry no equivalent cap, and larger amounts held for longer are common. FinTruction tracks retention receivable and retention payable outside the ordinary aging, by contract, with the release condition recorded against each balance.
California splits a construction contract between materials and fixtures under California Department of Tax and Fee Administration Regulation 1521. A contractor is generally the consumer of the materials it furnishes and installs, so tax is paid on the purchase price. For fixtures the contractor is generally the retailer, and tax applies to the fixture price. District taxes add a second layer, because rates vary between cities across Riverside County and the applicable rate can turn on where the material is used rather than where it was purchased. Equipment bought out of state and brought in carries California use tax.
Improve the three things a surety actually underwrites: working capital, equity and the credibility of the WIP schedule. For most growing Inland Empire contractors the bond, not the crew, is the ceiling on the next building. Underwriters also weigh how much backlog sits with a single owner, which is exactly the exposure this market creates. Retention buried inside accounts receivable, an unadjusted work in progress schedule and heavy equipment bought outright for cash all read badly. FinTruction produces statements in the form an underwriter reads and models what a machine purchase or a new award does to working capital before you commit.
Yes, through labor productivity rather than through the compliance cost itself. Title 8 of the California Code of Regulations, section 3395, requires access to shade, drinking water and cool-down rest for outdoor workers, with high-heat procedures applying on construction sites once the temperature reaches ninety-five degrees. In Riverside that means dawn starts, extra rest periods and slower concrete placement through July and August. A labor productivity rate derived from spring work will therefore overrun on a summer slab pour or grading phase. FinTruction tracks productivity by cost code and by period so estimating uses rates the work earns in this climate.
FinTruction works with contractors across Riverside and San Bernardino counties, including Riverside, Moreno Valley, Corona, Norco, Jurupa Valley, Eastvale, Perris, Menifee, Murrieta, Temecula, Hemet, Beaumont, Ontario, Fontana and Rancho Cucamonga. The practice is fully remote and the only office is in Coppell, Texas, which is why Inland Empire contractors get construction-specific accounting without paying toward premises they never visit. Sahil Ahmad, CPA reviews the work, so a licensed construction CPA signs off on the numbers your bank and your surety will read.
Pricing is a flat monthly fee set by transaction volume, number of active jobs and reporting needs, so calling with a question before you bid does not start a clock. The starting point is the free Audit. Send the current accounting file and the latest job profitability or WIP report, and FinTruction returns what is wrong with it, what that is costing, and what fixing it involves. There is no charge and no obligation for the Audit, and it is usually the fastest way to find out whether a large job is earning what the bid assumed.
