What a Construction Company's Accountant Costs: Returns, Bookkeeping, Job Costing, and the Statements Your Bonding Agent Wants

Contractors ask why their accounting bill is higher than their brother-in-law's consulting firm at the same revenue, and the answer is that construction accounting is a different discipline with more moving parts. The components and what drives each. Bookkeeping with job costing: standard bookkeeping (the bookkeeping-cost guide) plus the construction layer — every cost coded to a job and a cost type (labor, materials, subcontractors, equipment, overhead allocation), progress billings and retainage tracked by job, change orders recorded, work-in-progress schedules maintained, and the job cost reports produced that tell the contractor which jobs are making money; priced above the standard bookkeeping tier for the same transaction volume, because the coding is more granular and the reports are more, and scaling with the number of active jobs — a residential remodeler with six concurrent jobs is the low end, a commercial contractor with thirty is the high. Accounting method and revenue recognition: contractors choose (within the tax rules) among the cash method, the completed-contract method, and the percentage-of-completion method — with small contractors (under the gross-receipts threshold — an average-annual-gross-receipts test indexed to US$32 million for 2026, up from US$31 million in 2025) generally permitted the simpler methods for tax while their bonding agents and lenders often require percentage-of-completion for the financial statements, so many contractors maintain two computations; the method decision and the annual work-in-progress adjustment (the over- and under-billings computation) are the accountant's construction-specific work, priced into the return and the statements. Tax returns: the entity return (S corporation for most contractors, with the LLC-cost guide's classification analysis) carrying the construction items — the method computations, depreciation on equipment and vehicles (bonus depreciation and Section 179 on the fleet and heavy equipment, with the recapture planning the equipment-heavy trades need), the domestic production and energy-efficiency credits where they apply, the state returns for every state with a job, and the owner's return with the K-1 — priced above a service business's return of the same size by the construction items' hours. Payroll: multi-state and often multi-locality (the city wage taxes the payroll guide flags), prevailing-wage and certified payroll on public jobs, union reporting where applicable, and the subcontractor layer (1099-NEC for every subcontractor paid US$2,000 or more — the threshold the 2025 tax law raised from US$600 for payments made from 2026 — W-9 collection, backup withholding where a W-9 is missing, and the worker-classification exposure that construction draws more than any other industry — the classification guide) — priced above a standard payroll of the same headcount. Sales and use tax: the construction sales tax rules differ by state (materials taxed at purchase versus the installed price, contractor-as-consumer versus contractor-as-retailer, exemption certificates on exempt projects) and a contractor working across state lines carries a sales-tax compliance component that most service businesses don't — priced by the number of states and the transaction pattern. Financial statements for bonding and lending: the item that most separates construction accounting costs — surety bonding agents and construction lenders require annual financial statements at a level of service that scales with the bonding program: compilations for small programs, reviews for mid-sized ones, and audits for larger bonding lines and public work (the audit-cost guide's levels, with the construction-specific work — percentage-of-completion testing, the work-in-progress schedule, contract-level revenue and cost testing, retainage confirmations — making a construction audit more expensive than a service-business audit of the same revenue); the bonding statement is an annual engagement priced in the mid four figures for a compilation, low five figures for a review, and mid-to-high five figures for an audit of a contractor with a real program. Advisory: cash-flow forecasting by job (the item that keeps contractors solvent — the timing between costs incurred and progress billings collected is the industry's structural cash problem), equipment financing decisions, the entity and compensation planning, and — for growing contractors — the fractional CFO tier the advisory guide covers. The annual total, by contractor profile: a small residential contractor (one owner, a few employees, several jobs, no bonding) — job-costed bookkeeping, payroll, the entity and owner returns with one state — a mid-four-figure to low-five-figure annual total; a mid-sized general contractor (a dozen-plus employees, multi-state jobs, a bonding program requiring a review) — job costing at the higher tier, multi-state payroll and sales tax, the returns with several states, the annual review — a five-figure total, with the review a large single line; a commercial contractor with an audit requirement — everything above at scale plus the audit, in the higher five figures and beyond. What drives the fee up beyond size: the number of states and localities; the number of active jobs; bonding level (the statement's level of service is the largest single swing); the books' condition (job costing built from a shoebox is a reconstruction priced by the hour); the subcontractor count (each is a W-9, a 1099, and a classification question); equipment (each asset is depreciation planning and a recapture question); and public work (certified payroll and prevailing-wage compliance). How a contractor buys it well: a construction-experienced firm (the method, work-in-progress, and bonding-statement work is specialized, and a generalist learns it at the contractor's expense); job costing from day one (the retrofit is the expensive version); the bonding conversation with the surety before choosing the statement level (agents often accept a review where the contractor assumed an audit); the sales-tax registrations done before the first out-of-state job; and the subcontractor W-9 discipline installed before the first payment. Fairlight's construction bookkeeping, payroll, and return pricing is on the pricing page; the component structure above is what every construction engagement contains.

Key takeaways

• Construction accounting costs more for definable reasons: job costing, method and work-in-progress computations, retainage, subcontractor 1099s and classification, multi-state payroll and sales tax, and bonding statements.
• Components: job-costed bookkeeping (above the standard tier, scaling with active jobs); returns with construction items and multi-state filings; payroll with subcontractor compliance and certified payroll on public work; sales and use tax by state; the bonding statement (compilation, review, or audit — the largest swing); advisory on cash flow by job.
• Annual totals: mid-four to low-five figures for a small residential contractor; five figures for a bonded mid-sized GC with a review; higher five figures and beyond with an audit.
• The fee drivers beyond size: states and localities, active jobs, bonding level, books' condition, subcontractor count, equipment, and public work.
• Buy it well: a construction-experienced firm, job costing from day one, the surety conversation before choosing the statement level, sales-tax registrations before the first out-of-state job, W-9 discipline before the first subcontractor payment.
• The bonding statement's level is negotiable: many agents accept a review where the contractor assumed an audit — ask before buying.

The contractor's accounting budget

Active jobs and states. Employees and subcontractors. Equipment and vehicles. Bonding program and the surety's stated statement requirement (asked, not assumed). Books' condition (job-costed, or not yet). Public work (certified payroll). Price each component from the ranges above or from quotes on the same list, total for the year, and compare against the cost of the wrong level — an audit bought where a review was accepted, or a generalist's return that missed the method election. The budget is a page, and the bonding line decides its size.

Worked example

Three contractors at different scales. Contractor one: a kitchen-and-bath remodeler with four employees, six to eight concurrent jobs, one state, no bonding — job-costed bookkeeping at the lower construction tier, payroll for four, an S corporation return with the cash method and equipment depreciation, the owner's return; a low-five-figure annual total, with the job cost reports the item he says changed how he prices jobs. Contractor two: a commercial general contractor with sixteen employees, jobs in three states, forty subcontractors a year, and a surety requiring annual statements — job costing at the higher tier, multi-state payroll and sales tax, forty 1099s with W-9 discipline installed, the S corporation return with percentage-of-completion and three state returns, and — after his accountant asked the surety directly — a reviewed statement rather than the audit he'd assumed; a five-figure total in which the review is the largest line and roughly half what the audit would have cost. Contractor three: a heavy-civil contractor with sixty employees, public jobs in two states with certified payroll, a US$20 million bonding line, and an audit requirement — everything above at scale, the audit with percentage-of-completion testing across thirty contracts, and a fractional CFO for job-level cash forecasting; a higher five-figure total, with the audit and the CFO the two largest lines and the cash forecasting the one that kept a slow-paying public job from becoming a liquidity event. Three budgets, three scales, and in each the bonding conversation set the largest number.

Practitioner note

Construction accounting is priced by the industry's own moving parts — job costing, method computations, subcontractor compliance, multi-state payroll, and the bonding statement — and the bonding statement's level is the largest swing and the most negotiable. Our first question for any contractor is what the surety actually requires in writing, our second is whether job costing exists yet, and our standing advice is to buy construction-experienced help from the start, because the method election and the work-in-progress schedule are learned at the contractor's expense by anyone who hasn't done them.
