Bookkeeping for Cabinetry Companies

Running a cabinet shop is not like running a retail store. You quote custom work months before it ships, buy sheet goods and hardware for specific jobs, collect deposits up front, and carry half-finished cabinets on the floor for weeks. Ordinary bookkeeping misses all of that. Bookkeeping for cabinetry companies has to follow the money by job, or the numbers on your reports simply will not match what is happening in the shop.

This guide covers what makes cabinet-shop books different, the job-costing system that keeps them accurate, the mistakes that hide your real profit, and how to set it all up so every project shows you exactly where you stand.

Why bookkeeping for cabinetry companies is different

A cabinet business carries costs and revenue that a simple profit-and-loss cannot untangle on its own. Four things make it unusual:

• Every job is custom. Materials and labor differ from one project to the next, so “average” costs mean little.
• Deposits come first. You collect money before the work is done, which is a liability — not income — until you deliver.
• Work sits in progress. Materials and labor pile up on unfinished jobs long before you invoice.
• Materials are bought per job. Plywood, hardwood, hardware, and finish are tied to specific projects, not a general shelf.

Miss these and your monthly reports swing wildly — a huge profit the month a deposit lands, a loss the month you buy lumber — even when the business is steady. Cabinet shops share this with the broader trades, which is why the same discipline behind construction bookkeeping applies here.

Job costing: the heart of cabinet shop bookkeeping

Job costing means tracking every dollar of cost against the specific project it belongs to, then comparing that to what you billed. It is the single most important system in a cabinet shop, because it answers the question that matters: did this job actually make money?

A complete job-costing setup captures three cost buckets per project:

When those three are tracked per job and set against the invoice, you see true profit on every project — not just a lump number at month-end. That is how you learn that your frameless kitchens earn well but your built-in closets barely break even.

Handling customer deposits and progress billing

Most cabinet shops take a deposit — often 40% to 50% — before ordering materials. Here is the rule that trips owners up: a deposit is not income until you earn it. Booked as revenue the day it arrives, it inflates your profit and sets up a tax surprise on money you may still have to refund.

Correct handling looks like this:

1. Record the deposit as a liability (customer deposits or unearned revenue) when it lands.
2. Recognize revenue as you deliver — at milestones or on completion.
3. Apply the deposit against the final invoice so the customer is billed only for the balance.

For larger commercial jobs, progress billing works the same way: bill in stages tied to real progress, and match costs to the same periods so each month tells the truth.

Tracking materials and inventory in a cabinet shop

Materials are usually a cabinet company’s largest and most volatile cost, and how you track them decides whether your job margins are believable.

Buy to the job, not the shelf

Most custom shops expense materials directly to the job they were bought for rather than carrying a big inventory. This keeps job costs accurate and bookkeeping simple. If you keep a real stock of common sheet goods and hardware, that inventory belongs on the balance sheet until it is used.

Watch waste and price swings

Lumber and panel prices move, and offcut waste is real money. Tracking material cost per job over time shows when your estimates have fallen behind actual prices — a common reason shops feel busy but not profitable.

Labor, overhead, and your true shop rate

Custom cabinetry is labor-heavy, and undercounting labor is how shops lose money without noticing. Good bookkeeping ties shop and installation hours to each job, then adds an honest slice of overhead so you know your real cost to produce an hour of work.

That fully-loaded shop rate — wages plus payroll taxes, benefits, rent, utilities, equipment, and tool costs spread across billable hours — is the number you should be quoting from. Shops that quote off wages alone almost always underprice. Clean payroll for construction and trades data feeds this directly, since labor burden starts with accurate payroll.

Sales tax on cabinets: materials vs. installation

Sales tax on cabinetry is genuinely tricky and varies by state. Whether you charge tax on the cabinets, the installation, or both often depends on whether the work is a retail sale or a capital improvement to real property, and on your state’s rules. Installed built-ins are frequently treated differently from cabinets sold over the counter.

The safe approach: separate materials and installation on your invoices, track tax collected as a liability, and confirm your state’s treatment with your state and local tax authority or your CPA. Getting this wrong is a common audit trigger for shops that do both fabrication and installation.

Equipment, tools, and depreciation

Cabinet shops run real capital: CNC routers, panel saws, edgebanders, dust collection, spray booths. These are assets, not expenses — they go on the balance sheet and depreciate over time, and some qualify for accelerated deductions like Section 179. Good bookkeeping tracks each major asset, its depreciation, and the loan or lease behind it, so your balance sheet is accurate and your tax deductions are captured.

The right software for cabinetry bookkeeping

Most cabinet companies run their books on QuickBooks Online with job costing turned on. It handles projects, customer deposits, progress invoicing, and class or location tracking for multiple crews — enough for the large majority of shops. Larger operations sometimes add a dedicated shop-management or estimating tool that feeds costs back into the accounting file.

Whatever the platform, the setup is what matters: a chart of accounts built for a shop, projects enabled, deposit and WIP handling configured, and bank feeds connected so nothing is entered twice. A generic setup is what leaves owners guessing.

Benefits of proper bookkeeping for cabinetry companies

• You know which jobs make money. Job costing turns gut feel into numbers.
• Your quotes get sharper. Real cost data means estimates that hold up.
• Deposits stop distorting your books. Profit reflects work delivered, not cash received.
• Cash flow gets predictable. You see material buys and slow stretches coming.
• Tax season is calm. Clean, job-costed books hand straight to your CPA.
• You look ready for lenders. Banks financing equipment want accurate financials.

Common bookkeeping mistakes cabinet shops make

• Booking deposits as income. Inflates profit and creates a tax surprise on unearned money.
• No job costing. Without it you cannot tell a profitable job from a money-loser.
• Ignoring work in progress. Unfinished jobs full of cost make monthly numbers meaningless.
• Undercounting labor and overhead. Quoting off wages alone quietly underprices every job.
• Mixing materials across jobs. Lumping purchases together destroys job accuracy.
• Mishandling sales tax on installs. A frequent audit trigger for fabricate-and-install shops.

Best practices for cabinet company bookkeeping

1. Set up job costing from the start — every cost tagged to a project.
2. Record customer deposits as a liability, not revenue.
3. Track work in progress so unfinished jobs do not skew the month.
4. Buy and code materials to the specific job whenever possible.
5. Capture all shop and install labor, then add loaded overhead to find your true rate.
6. Reconcile every account monthly and review job-profit reports, not just the P&L.
7. Separate materials and installation on invoices for clean sales tax.

Understanding work in progress (WIP)

Work in progress is the value of cabinets you have started but not yet delivered — the materials and labor sitting in half-finished jobs on your floor. It is one of the most overlooked numbers in cabinet shop bookkeeping, and ignoring it is why a shop can look unprofitable one month and flush the next.

Here is the problem: if you expense all your materials and labor as you incur them but only record revenue when a job ships, every month with lots of unfinished work looks like a loss. Tracking WIP holds those costs on the balance sheet until the job is delivered, then matches them against the revenue in the same period. The result is a monthly profit number that actually reflects how the business is doing — not just which jobs happened to close that month.

You do not need to value WIP perfectly to the penny. Even a simple, consistent method — costs accumulated per open job — makes your financials far more honest and useful.

Reading your cabinet shop’s financial reports

Bookkeeping is only worth it if the reports drive decisions. Three reports matter most for a cabinet company:

• Job profitability report: the most important one — profit by project, so you see which work earns.
• Profit & loss: overall performance, with materials, labor, and overhead broken out.
• Balance sheet: deposits, WIP, equipment, and loans — the true financial position.

Reviewed monthly, these turn your books from a tax chore into a management tool. The job report in particular is where owners discover that their busiest product line is not their most profitable one.

Managing cash flow in a cabinet business

Cabinet shops face a specific cash-flow squeeze: you buy materials and pay labor well before a job is finished and paid in full. Deposits help, but a shop that takes on several big jobs at once can be busy and still short on cash. Good bookkeeping shows the pattern early — upcoming material buys, payroll, and the timing of final payments — so you can stage purchases and billing instead of scrambling. Seasonality matters too; many shops slow in winter, and reconciled books let you plan for it rather than feel it.
