A cabinetmaker or millwork contractor runs a job through two distinct places — the shop, where fabrication happens, and the field, where it's installed — and most trades we cover only have one. Cabinetmaker and millwork contractor bookkeeping has to allocate shop overhead correctly, track custom design lead time, and cost materials that vary enormously by wood species and hardware.
This guide covers what's genuinely different about construction bookkeeping for a cabinetmaking and millwork business: shop-versus-field cost allocation, design-to-fabrication lead time, and material cost variance. If you want construction cost accounting built around how this trade actually works, this is for you.
1. Shop and Field Are Two Different Cost Centers
Fabrication happens in a shop with its own overhead — rent, equipment, and labor that exist whether or not a job is currently being built — while installation happens in the field with its own labor and travel cost. Millwork contractor bookkeeping needs to allocate shop overhead to jobs correctly, since a shop-based business has a fixed-cost structure that a field-only trade doesn't carry.
SHOP vs FIELD — TWO COST CENTERS, ONE JOB
A cabinet or millwork job runs through two distinct cost centers that need separate tracking
Shop | Fabrication labor, shop equipment depreciation, shop rent and utilities — costs that exist whether or not a job is currently in the shop |
Field | Installation labor and travel — a separate cost phase that happens after fabrication is complete |
⚠ RED FLAG: If shop overhead isn't allocated to jobs at all, or is allocated on a rough guess instead of actual shop hours per job, every job cost report understates what fabrication actually costs — and pricing custom work becomes a guess. |
2. Design-to-Fabrication Lead Time
Custom cabinetry and millwork often involve a real gap between design approval, deposit, and the start of fabrication — similar to the deposit timing questions other custom-product trades face. Construction bookkeeping for this trade should treat a deposit as a liability until the work is actually performed, consistent with U.S. GAAP revenue recognition, rather than recording it as revenue the day it's collected — the same GAAP treatment that applies to any deposit-based custom trade.
OWNER'S TAKEAWAY: Treat design deposits as unearned revenue until fabrication and installation are complete. For custom work with a real lead time between deposit and delivery, that distinction keeps your P&L from overstating income you haven't actually earned yet. |
Is Your Shop Overhead Actually Allocated to Jobs?
Most cabinetmakers and millwork shops absorb shop overhead into general expense instead of allocating it to jobs. CCA builds bookkeeping that costs the shop correctly. In a free 30-minute review, we'll show you where your numbers stand.

3. Material Cost Variance by Species & Hardware
Wood species and hardware selections can swing material cost dramatically on jobs that look similar in scope. Cabinetmaker bookkeeping and cabinetmaker and millwork contractor bookkeeping need to track material cost by job against the bid, since a customer's mid-project upgrade to a different species or hardware line changes the job's economics in a way that needs to be captured, not absorbed.
A cabinet job's real cost lives in two places most trades never separate — what it took in the shop, and what it took in the field. Blend them, and you're pricing custom work on a guess. |
4. The Reports a Cabinetmaker & Millwork Contractor Needs
Pulling this together, here's what a cabinetmaking and millwork business should see every month:
Job cost by shop and field — fabrication and installation cost tracked separately against the bid
Deposit liability tracking — design deposits recognized as revenue only when the work is complete
Material cost by job — species and hardware selections tracked against the bid, including mid-project changes
Financial statements — P&L and balance sheet on a set schedule each month
With those in place, a cabinetmaker or millwork contractor knows true shop and field cost, correct revenue timing on deposits, and real material cost by job. That's construction accounting doing its job for a trade that fabricates before it ever sets foot on a job site.

Cabinetmaker and millwork contractor bookkeeping has to reflect what the trade actually is: fabrication in a shop with its own overhead, installation in the field with its own cost, custom design deposits that need correct revenue timing, and material cost that varies by species and hardware. Allocate shop overhead to jobs, treat deposits as liabilities until complete, and track material cost against the bid.
