Bookkeeping for Texas Construction Companies: Job Costing, WIP, and Cash Flow

Construction is one of the hardest industries to keep books for and one of the most expensive to get wrong. A contractor can look profitable on the company P&L while individual jobs bleed cash — and nobody knows until the project closes out and the surprise lands.

Texas construction activity remains a major part of the regional economy, with steady movement in nonresidential and infrastructure work. But volatile material, fuel, and labor costs make job-level accuracy non-negotiable. Standard small-business bookkeeping treats a contractor like a service company and systematically hides the truth.

A construction-specific chart of accounts

Generic charts of accounts lump all costs together. A construction chart separates direct job costs (labor, materials, subcontractors, equipment, other) from overhead, and supports cost codes so you can see spending by phase and category. This structure is the foundation everything else sits on — without it, job costing and WIP are guesswork.

Job costing: tie every dollar to a project

Job costing means every transaction — a lumber invoice, a sub's payment, a crew's hours, fuel for a piece of equipment — is tagged to the specific job it belongs to. The payoff is the ability to compare estimated vs. actual cost by job, in real time, so you catch an overrun while you can still do something about it.

Burdened labor matters here: load payroll taxes, workers' comp, and benefits into your labor cost so a job's true cost isn't understated by 20–30%.

WIP schedules and revenue recognition

Work-in-progress reporting is what separates real construction accounting from bookkeeping that merely looks organized. A WIP schedule compares costs incurred to estimated total costs (percent complete), then to amounts billed — revealing over-billings (you've billed ahead of work, a liability) and under-billings (you've done work you haven't billed, an asset).

WIP keeps the company P&L tied to job-level reality and is increasingly required by sureties and lenders for bonding capacity. Reviewed monthly, it tells you which jobs are healthy and which are quietly slipping.

Retainage and change orders

Retainage — the percentage held back until completion — has to be tracked separately as retainage receivable and retainage payable, or your AR, AP, and cash forecast will all be wrong. It's real money, just delayed, and it's a frequent cause of cash strain on otherwise profitable jobs.

Change orders are the other silent margin killer. Work performed without an approved, booked change order is work you may never get paid for. Track them as a disciplined process: scope, price, approval, and entry into the job cost before the crew starts the extra work.

Equipment, fuel, and the volatile cost lines

Equipment purchases need proper fixed-asset records (cost, purchase and placed-in-service dates) for depreciation — see our CPA-ready records guide. Fuel, materials, subcontractor, and labor costs are where inflation hits hardest, so allocate them to jobs and watch the trend; an estimate built on last year's prices can turn a winning bid into a loss.

The reports owners should review monthly

Every month, review: a job-cost report (estimated vs. actual by job), the WIP schedule, an AR aging that separates retainage, a change-order log, and the company P&L and balance sheet. Together these answer the only questions that matter — which jobs make money, where cash is tied up, and what's coming.

This is exactly the kind of job-level discipline our construction bookkeeping work and, where needed, fractional-CFO support are built to deliver.
