QuickBooks cleanup · Construction

QuickBooks cleanup for construction companies.

When job costs land on the company instead of the job, retainage hides inside receivables and nobody keeps a WIP schedule, the books can look fine while jobs quietly lose money. We rebuild job costing, WIP and retainage in your own QuickBooks file, on a written fixed-fee scope, and hand you books that show profit job by job.

TL;DR

A construction cleanup reassigns costs to the jobs and cost codes they belong to, separates retainage receivable and payable, rebuilds the work-in-progress schedule with over- and under-billing, ties certified payroll to payroll, and completes subcontractor records. It is done in your own QuickBooks file on a written fixed-fee scope, and leads into monthly construction bookkeeping if you want it kept clean. Your CPA confirms the revenue-recognition method and files.

Quick answers

Construction cleanup, in five questions.

What is a construction QuickBooks cleanup?

Rebuilding a contractor’s books job by job: costs reassigned to jobs and cost codes, retainage separated, a WIP schedule rebuilt with over- and under-billing, and certified payroll tied to payroll.

Why can’t I see profit by job?

Because costs were posted to general expense accounts instead of to jobs. Job profit only exists in QuickBooks when every cost carries a job.

What is over- and under-billing?

The difference between what you have billed on a contract and what you have earned by work completed. It belongs on the balance sheet, from the WIP schedule.

Do you handle retainage?

Yes — retainage receivable and payable are tracked separately from ordinary receivables and payables until they are released.

Who chooses percentage-of-completion or completed-contract?

Your CPA. It is a tax and accounting-method decision; TechBrot keeps the books ready for whichever method your CPA confirms.

§The problem

Why contractors’ books drift.

Construction books have to answer a question ordinary books do not: which jobs make money. That needs every cost posted to a job and a cost code, billing tracked against the contract, and retainage held apart until it is released.

When materials go to “supplies”, crews go to “payroll” and progress billings go straight to income, the company total can look healthy while individual jobs run over — and the balance sheet overstates what has been earned or understates what is owed.

§What we find

What a construction cleanup turns up.

Costs posted to the company, not the job

Materials, labor and subcontractors in general expense accounts, so job profit is invisible.

Retainage inside receivables and payables

Money held back on progress billings mixed into ordinary receivables, overstating what customers owe now.

No WIP schedule

Billings never compared with work earned, so over- and under-billing never reach the balance sheet.

Certified payroll that does not tie

Prevailing-wage reports that do not match what payroll actually paid on public work.

Subcontractor records incomplete

Missing W-9s, vendors not flagged for 1099 reporting, and certificates of insurance nobody tracks.

§How we clean it up

Job by job, cost code by cost code.

STEP 1

Map jobs and contracts

Open and recently closed jobs, contract values, change orders and billing to date.

STEP 2

Reassign costs

Materials, labor, equipment and subcontractors reclassified to the right job and cost code.

STEP 3

Separate retainage

Retainage receivable and payable split out and tracked to release.

STEP 4

Rebuild WIP

A work-in-progress schedule with over- and under-billing, tied to the balance sheet.

STEP 5

Tie payroll and subs

Certified payroll to payroll, subcontractor records completed, and the books handed over CPA-ready.

§When to call

Three signs it is past a quick fix.

You cannot tell which jobs made money

The company profit and loss is the only profit number you have.

Your bonding agent or lender wants a WIP schedule

And there is nothing in QuickBooks to build one from.

Year-end surprises from your CPA

Adjustments for retainage, over-billing or misclassified costs arrive after the year closes.

§Pricing

What a construction cleanup costs.

Construction cleanups are priced as QuickBooks cleanup (published at $1,200–$15,000+), fixed fee against a written scope that names the jobs and the months. The number of active jobs, how far behind the file is, and whether WIP must be rebuilt from scratch set where a cleanup lands.

Whether you report on percentage-of-completion or completed-contract is a tax and accounting-method decision for your CPA; we keep the books ready for either.

Questions about cleaning up a contractor’s books.

How much does a construction cleanup cost?
It is priced as QuickBooks cleanup, published at $1,200–$15,000+, fixed fee against a written scope that names the jobs and months. The exact figure is in the scope before work starts.
Can you rebuild job costing for jobs that are already finished?
Yes, from invoices, bills, payroll records and contracts. The scope states which jobs and periods are rebuilt.
Do you prepare certified payroll reports?
We support certified payroll for prevailing-wage and public work and tie the reports to payroll. Complex union or multi-state prevailing-wage cases are scoped openly on the discovery call.
Will my bonding agent accept the WIP schedule?
The schedule comes from reconciled books and ties to the balance sheet. What a surety requires is its decision; statements we prepare are unaudited and provide no assurance.
Is TechBrot a CPA firm?
No. TechBrot is an independent bookkeeping and advisory firm, not a CPA firm, and does not perform audits, reviews, compilations, or income-tax filing.
