Bookkeeping services for homebuilders have one job that generic bookkeeping misses: showing what each house, lot, or custom contract actually cost and earned — not just what the company made in total. A homebuilder can have a profitable year on the P&L while two spec houses quietly lose money, a custom job's upgrades never get billed, and buyer deposits sit in the bank looking like revenue. Homebuilder bookkeeping keeps each house on its own job, ties construction loan draws to real costs, and closes every month so you can make the next land, bid, or pricing decision on numbers you trust.
This page covers how the books differ for spec and custom builders, how to job-cost by house and phase, how draws, deposits, selections, and closings should hit the books, and what a monthly close should give a builder. If you're a specialty trade working for builders, see specialty trade bookkeeping instead.

Many builders do both, and the books need to know which is which.
| Custom / contract homes | Spec homes | |
|---|---|---|
| Who the customer is | A buyer who signed a contract before or during construction | No buyer yet (or a buyer under a purchase contract to close at completion) |
| How money comes in | Deposits, progress payments or draws, final payment | Construction loan draws during the build; sale proceeds at closing |
| What the books track during the build | Contract value, costs, earned vs billed — a WIP schedule | Costs building up on the house, usually on the balance sheet until sale |
| Where margin shows | Through the job as it's earned, then confirmed at completion | At closing, when the sale is recorded against the house's total cost |
| Biggest bookkeeping risk | Unbilled change orders, under billing, deposits booked as revenue | Costs coded to the wrong house, loan interest and carrying costs lost in overhead, closing statements booked as one lump |
On a phone, scroll sideways to compare custom and spec homes.
Exactly how and when revenue is recognized, and which costs (including construction loan interest, land, and carrying costs) are capitalized into each house, is a decision for your CPA. Our job is to keep the records clean enough that whatever method your CPA sets can be applied the same way every month. For contract work, see percentage of completion.
The foundation of homebuilder bookkeeping is simple to say and hard to keep up: every cost lands on the right house, in the right phase, when it's entered — not corrected at year-end.
A simple example with made-up numbers: a builder has three spec houses in one community, each budgeted at $310,000. Supplier invoices for a shared framing package get coded to whichever house the bill was entered against. On paper, House 1 runs $40,000 over and Houses 2 and 3 look $20,000 under. In reality all three are close to budget — but the builder raises the price on House 1's plan and keeps the others where they are. Clean coding would have shown three houses on budget and no reason to change pricing at all.
Most builders fund houses with construction loans released in draws. The books should make every draw easy to back up — and keep borrowed money out of revenue.
For the full draw package — schedule of values, backup, and waivers — see draw packages. For contract homes billed on AIA forms, see AIA billing. For waivers from subs and suppliers, see lien waiver tracking.
Custom and pre-sold homes bring buyer money in before the house is done. How it's recorded decides whether your financials tell the truth.
The closing statement is the most detailed financial document a spec or pre-sold house produces, and it's often booked as one number. Book it line by line:
Then close the house out: move its accumulated cost into cost of sales (per your CPA's method), compare final cost against budget, and keep the variance. That closed-house history is what tells you whether your next plan is priced right.
After closing, warranty work keeps coming. Track warranty costs by house and community so you can see which plans, trades, or communities generate the most callbacks. Whether to record a warranty reserve, and how, is a question for your CPA.
Remodelers face the same problem at a smaller ticket size: lots of jobs open at once, frequent change orders, and margin that disappears into unbilled extras. The fix is the same — every remodel is its own job, change orders are logged and billed as they happen, and job cost reports are reviewed monthly while the job is still open. See job costing and specialty trade bookkeeping for small-ticket job costing.
A real monthly close for a builder is more than reconciled bank accounts. By the 15th, you should be able to see:

If you answered "no" to three or more, the books are probably hiding house-level losses or gains you'd price differently if you could see them.
Blackline is a construction-only bookkeeping, monthly close, and fractional CFO firm for contractors doing roughly $1M–$30M in revenue, including homebuilders and remodelers. We're listed in the Home Builders Association of Central Arizona member directory. We don't do tax prep — tax questions, revenue recognition methods, and cost capitalization go to your CPA — and we don't give legal advice.
Every engagement starts with a DIG Diagnostic, and every package is custom-quoted. See services and packages.
We work with builders and remodelers throughout the Phoenix metro from our Mesa office:
House-level job costing by phase or cost code, construction loan and draw tracking, customer deposit tracking, selections and change orders, closing statements booked line by line, warranty cost tracking, and a monthly close with budget-vs-actual for every open house.
A custom home is a contract with a buyer, so the books track contract value, costs, and earned vs billed on a WIP. A spec home has no buyer during construction, so costs typically build up on the balance sheet until the house closes. Your CPA sets the revenue recognition and cost capitalization method for each.
No. Draws are borrowed money and should be recorded against the construction loan, not as revenue. Sale proceeds at closing pay the loan off.
Usually as a customer deposit liability, tracked by buyer and house, until the contract and your CPA's method say they're earned or applied at closing. Contract and deposit-handling questions go to your attorney.
Yes. One job per house or lot, with costs coded by phase or cost code that matches your estimate, is what makes budget-vs-actual and final house margin possible.
Yes. Remodelers need the same discipline at a smaller ticket size — every job separate, change orders logged and billed as they happen, and job cost reviewed monthly while jobs are open.
No. Blackline doesn't do tax prep. We keep the books clean and organized for your CPA, who handles tax returns, revenue recognition methods, and cost capitalization.
If you can't say which houses made money last year — or you won't know until the CPA finishes the return — start with the DIG Diagnostic. We'll look at how costs, draws, deposits, and closings are landing in your books and show you what a monthly, house-level close would look like.
