Don't Know Which Jobs Made Money? We Track Every Dollar by Project.

Construction bookkeeping is different from regular bookkeeping because the profit lives at the job level. Catalyst CPA sets up job costing inside QuickBooks Online and tags every expense, invoice, and payment to its project as it lands in your books — materials, labor, subs, and overhead — under California CPA license #158599. You get a per-job profit report every month.

A construction company can be profitable on paper and still be losing money on half its jobs. If your books show one revenue number and one pile of costs, you cannot see which half. That is the problem we built our in-house automation to fix: project-level books without paying for a separate job-costing platform on top of a bookkeeper.

Construction Bookkeeping Problems We Fix

These are the calls we actually get from contractors.

Job Costs Lumped Into One Account

Materials, labor, and subs all posted to one expense line. No job costing means no job margins — we rebuild the file so every cost carries its project.

Over- and Under-Billing You Cannot See

Progress billing that has drifted from actual completion hides profit swings. A monthly work-in-progress schedule shows exactly where each contract stands.

No WIP Schedule for the Bank or Bonding Company

Lenders and sureties ask for work-in-progress reporting. We produce a WIP schedule an underwriter can actually read, tied to your books.

Retainage Nobody Is Tracking

Retention withheld on your invoices is your money. If it is not tracked as a receivable, it gets forgotten — and taxed wrong.

Months Behind Mid-Project

Jobs running while the books sit untouched since spring. We catch up oldest month first so each period closes clean and the open jobs get real numbers.

Materials, Labor, and Subs Commingled

Cost type matters: markup, 1099 reporting, and workers comp audits all depend on knowing what was material, what was wage, and what was subcontract.

No Per-Job Profit Report

You finished the job. Did it make money? We answer that with a job profitability report every month, not a shrug in April.

Paying for Job-Costing Software on Top of a Bookkeeper

Dedicated job-costing platforms commonly run $99-$199+ per month before per-user fees. We do the job costing inside QuickBooks Online, so many clients drop the extra subscription.

Job Costing & Construction Bookkeeping Services We Provide

One firm for the books, the job costing, the 1099s, and the tax return. Construction bookkeeping runs $500–$1,200/month depending on job volume and number of active projects, quoted flat after a free review of your file — call (951) 223-1826.

Job Costing Setup in QuickBooks Online

Projects, cost codes, and item structure built for how you actually bid and build. Our in-house automation tags each expense and payment to its job as it hits the books.

Percentage-of-Completion & WIP Reporting

Earned revenue, over/under-billings, and a work-in-progress schedule computed monthly — the reports banks, sureties, and good decisions run on.

Progress Billing & Retainage Tracking

Draws and progress invoices tied to the contract, retention tracked as its own receivable, and change orders recorded instead of lost.

Monthly Per-Job Profitability Reports

Every month you see each job's revenue, costs by type, and margin — plus budget versus actual, so a job that is bleeding shows up while you can still fix it.

Catch-Up Construction Bookkeeping

Behind six months with three jobs running? We rebuild oldest month forward, job-tagged from the start, so the file ends current and stays current.

1099 Subcontractor Compliance

Sub payments tracked all year with W-9s collected as vendors are set up, then 1099-NEC forms e-filed with the IRS at the January deadline.

Trades We Serve

Bookkeeping for contractors across the trades — residential and commercial, from a two-person crew to multi-crew operations.

General Contractors & Remodelers

Multi-phase jobs, subs on every project, draws and change orders — the full job-costing picture.

Bookkeeping for Painters

Crew labor versus materials by job, so you know your real cost per square foot and which estimates hold up.

Bookkeeping for Plumbers

Service calls and contract jobs split correctly, parts inventory costs tied to the work that used them.

HVAC Contractors

Install jobs costed separately from service work, equipment purchases matched to the job they went into.

Electricians

Job materials and labor tracked per project, progress billing on commercial work handled cleanly.

Roofers

Insurance jobs and retail jobs separated, supplements tracked, crew costs tied to each roof.

Landscapers

Install projects costed job by job, maintenance routes tracked as recurring revenue with their own margins.

Concrete & Flooring

Material-heavy jobs where yardage and waste decide the margin — costs tagged to the pour or the install.

Not in construction? We do the same per-project books for agencies, architects, engineers, and other project businesses — see our job costing services.

Construction Bookkeeping — Frequently Asked Questions

How much does construction bookkeeping cost?

Construction bookkeeping with job costing runs $500–$1,200/month depending on job volume and number of active projects. After a free 30-minute review of your file we quote a flat monthly fee, so you know the number before any work begins. Call (951) 223-1826 to set it up.

Do I need to buy job-costing software?

Usually not. Dedicated platforms commonly run $99-$199+ per month before per-user fees — Knowify starts at $99/month and JobTread runs $199/month plus $20 per user, per their published pricing. We do job costing inside QuickBooks Online with our own automation, so many clients skip the extra subscription. If you already use one of those tools and like it, we work from its reports instead.

What is percentage-of-completion accounting and do I need it?

Percentage-of-completion recognizes revenue as a job progresses instead of when it finishes. Most contractors with average annual gross receipts of $32 million or less (2026, indexed annually) whose contracts finish within two years are exempt from the required method under IRC section 460 — but your bank or bonding company may still want POC-basis financials, and for managing jobs the WIP math is worth having either way. We tell you what your situation actually requires.

Can you catch up books in the middle of active jobs?

Yes. We work oldest month forward and tag historical costs to their jobs as we go, so by the time the file is current your open jobs have real cost-to-date numbers, not estimates.

How do you track costs to each job?

We set up QuickBooks Online projects and cost structure to match how you bid, then our in-house automation tags each expense, bill, and payment to its job as it lands in the books. You see cost by job and by type — materials, labor, subs — every month.

Do you also do the taxes?

Yes. The same firm that keeps the job-costed books prepares the business return, so the accounting method, the WIP, and the return line up instead of being three different stories.
