Zachary Schwarz CPA — Accounting & Tax Services
Who I work with

Accounting for construction companies and trades

Contractors, subcontractors and trades run on jobs that span months, billing that does not match the work, and margins that hide until the job closes. Accounting built around WIP and job cost shows which work actually makes money while there is still time to act on it.

What the books need to handle

Job costing that ties out

Labor, materials, equipment and subs coded to the job they belong to, so every project has a real margin rather than a guess made at the end.

Monthly WIP and over/under billings

Costs to date against billings and estimates to complete, reviewed every period, with the entry that brings revenue in line with work performed.

Retainage and progress billing

Retainage tracked as its own receivable, progress billings reconciled, and the aging kept honest so you know what is collectible now.

Surety, bonding and lender reporting

Accrual statements and WIP schedules prepared in the format sureties and banks typically ask for, so the quality of the books isn’t what holds back bonding or credit.

Equipment and vehicles

Fixed asset schedules, depreciation, and the tax decisions on large purchases planned before the equipment is bought, not after.

Home services and residential trades

HVAC, plumbing, electrical, roofing and other home service companies mix quick service calls with larger install and replacement projects. The books need to handle both.

Service calls and project work

Short service tickets and longer installs tracked separately, so you can see which side of the business is carrying the margin.

Technician pay and productivity

Hourly, flat-rate and commission pay run through payroll correctly, with revenue and gross profit reported per technician.

Maintenance plans and memberships

Service agreements paid up front recognized as the visits happen, not all at once when the cash comes in.

Trucks, parts and warranty work

Fleet costs, parts stocked on trucks and warranty callbacks tracked so vehicle and material costs do not disappear into overhead.

Numbers worth tracking monthly

Margin fade by job

Estimated margin at bid against current projected margin, so fade shows while the job is still running.

Net over/under billing

Overbilled or underbilled across open jobs. Heavy overbilling means cash is ahead of the work.

Backlog

Contracted revenue not yet earned, and the gross profit it carries.

Labor burden rate

Payroll taxes, insurance and benefits as a share of wages, so bids price labor at its true cost.

Balance sheet accounts I keep workpapers on

Each of these is supported every month by a workpaper that ties the balance to a source document, so the number can be trusted and followed by anyone who reviews it.

Contract receivables and retainage

Aged by job and reconciled to billings, with retainage shown separately so the collectible balance is clear.

Underbillings

Costs and estimated earnings in excess of billings, supported job by job by the WIP schedule.

Overbillings

Billings in excess of costs and estimated earnings, carried as a liability until the work catches up.

Accrued job costs

Subcontractor and supplier costs incurred but not yet invoiced, so each month carries its real cost.

Month-end close for contractors

Tax

Tax considerations

Long-term contract method

Percentage of completion, completed contract and other methods may be available depending on contract length and business size. The choice changes when income is taxed and can differ from the method used on your statements.

Equipment purchases

Large purchases can often be expensed in the year bought instead of depreciated over time. Whether that is right depends on this year’s income and the next few years.

Work in other states

Jobs outside your home state can create income tax, payroll and contractor registration obligations there.

Subcontractors and workers

W-9s collected before the first payment, 1099s filed on time, and classification reviewed for workers who look more like employees.

How I help

Common questions

Do you work with subcontractors as well as general contractors?
Yes. Subcontractors deal with the same WIP, retainage and cash-timing issues as general contractors, often on thinner margins, and benefit from the same monthly job-level view.
Can you work with my job-costing or construction software?
Most likely. I work in QuickBooks and the common construction and job-costing systems. If the current setup is not producing reliable job reports, the fix is usually in how costs are coded rather than the software itself.
Why does my bank want a WIP schedule?
Because the income statement alone can make a contractor look healthier or weaker than it is. The WIP schedule shows whether revenue has been recognized ahead of or behind the work, which tells a lender or surety how reliable the reported profit is.
