Construction Deposits: Held or Spent?
A construction deposit sounds like money that waits for you. It pays for the work instead. Here is how Buildplus keeps every dollar of it visible, from the first payment to the last invoice credit.
This article provides general business information, not legal or financial advice. Contract terms and state laws vary. Review your specific agreement with a qualified attorney.
A homeowner signs a contract and pays a $100,000 deposit. Two weeks later, most of that money is framing lumber stacked on the lot.
Nothing went wrong. That is exactly what a construction deposit is for. But if the homeowner pictured the money sitting in an account, waiting, the way a rental deposit waits, that stack of lumber can feel like a broken promise.
The trouble is one word with two meanings. Contractors use "deposit" to mean the money that starts the work. Most homeowners learned the word from apartment leases and hotel bookings, where a deposit is money you still own and get back at the end. Both parties sign the same contract and read two different agreements.
Usually nobody notices until a project slows down, changes scope, or ends early. Then one question arrives all at once: where is my deposit?
Buildplus answers that question before anyone has to ask it. The deposit has its own balance, tracked beside the project's cash. Every invoice shows how much of it has come back to the owner and how much remains.
Held or spent?
When you see "deposit" in a contract, ask two questions: is this money held or spent, and how does it come back?
| Security deposit | Construction deposit | |
|---|---|---|
| Where the money goes | Held, often in a separate or escrow account | Spent on materials, labor, and mobilization |
| How it comes back | Returned when you meet the conditions | Credited against the contract price on later invoices |
| When it is refundable | By default, less any valid deductions | Only as the contract or the law provides |
A construction deposit is a down payment by another name. The contractor spends it, and the owner gets its value back as credit against the price.
The accounting agrees. Until the contractor earns it, a customer deposit is a liability on the contractor's books: the contractor owes the owner that value in work or credit. The obligation stays real after the cash is spent. That is why the deposit deserves its own balance, and why Buildplus gives it one.
How Buildplus handles a deposit
In Buildplus, the deposit is held by the project, spent on the project, and credited back to the owner on invoices. Here is the full path.
1. The owner pays a deposit invoice
The general contractor sets up the project deposit with a deposit invoice. Issuing it invites the project owners to Buildplus, where they can review the project and pay online. Buildplus doesn't charge its invoice fee on deposit invoices.
2. The deposit gets its own balance
The payment lands in the project's own bank account. That account is in the contractor's company name, separate from the company operating account and from every other project.
Buildplus records the payment as a customer deposit: a balance the project owes back to the owner. It stays out of accounts receivable, because the owner has not been billed for any work yet and the deposit settles no invoice. Buildplus tracks the deposit balance beside the project's cash balance and records the same money on the owner's side of the ledger as their project deposit.
3. The deposit carries the work between invoices
The contractor pays suppliers and trades from the project account. Cash goes down. The deposit balance stays the same, because the owner has not yet received credit for any of it.
This is the job a construction deposit does. It pays for mobilization, material orders, and early labor, and it carries the project from one invoice to the next without the contractor fronting its own money.
4. Each invoice credits some of it back
Every invoice has a Deposit Credits section that shows the current deposit balance. The contractor adds a deposit credit inline, and it stays editable while the invoice is a draft. When the invoice is issued, the credit applies and the deposit balance goes down by the same amount. The owner sees the credit on the invoice and on its PDF.
It works in reverse too. If an owner pays more than an invoice asks for, the contractor can convert the overpayment into deposit balance for later invoices.
5. The $100,000 deposit, step by step
Back to the homeowner and the lumber, simplified to ignore fees and retainage:
| Step | Project cash | Deposit balance |
|---|---|---|
| Owner pays a $100,000 deposit invoice | $100,000 | $100,000 |
| Contractor pays $80,000 for framing and lumber | $20,000 | $100,000 |
| Invoice 1 bills $80,000 with a $10,000 deposit credit | $20,000 | $90,000 |
| Owner pays the $70,000 balance of Invoice 1 | $90,000 | $90,000 |
Between invoices, cash and the deposit balance separate. The gap shows how much of the deposit is at work. When the owner pays, the two meet again, and the lower deposit balance shows how much credit the owner has left.
Later invoices keep applying credits until the balance reaches zero, usually by the final invoice. No one has to rebuild the deposit's history from a spreadsheet or dig it out of a lump sum.
What each side gets
Homeowners can see where their deposit stands at any time. Each credit appears on the same invoice as the costs it offsets. "Where is my deposit?" has a number for an answer.
General contractors get the cash to start a job and keep it moving between billing cycles, without mixing that cash into the operating account or another project. The deposit stays a liability until it is credited, so project cash never passes for profit.
What is Buildplus?
Buildplus is the payments, expenses and invoicing platform built for contractors running cost-plus jobs. Every payment, swipe and reimbursable expense stays tied to the project it belongs to.
A note on California
California limits deposits on home improvement work. Under Business and Professions Code §7159.5, a down payment can be no more than $1,000 or 10 percent of the contract price, whichever is less. After that, a contractor can't request or accept payment that exceeds the value of the work performed or materials delivered. Section 7159 requires the contract to state the limit in at least 12-point boldface type. Violations can be misdemeanors and can lead to license discipline.
The rules cover repairs, remodels, and additions to residential property, including the rebuild of a home destroyed in a declared natural disaster (§7151). Ground-up homes on vacant lots are generally treated as new construction, outside these rules. Contractors with an approved performance and payment bond or approved joint control are exempt from the cap. If a project sits near the line, ask counsel.
Buildplus doesn't set or enforce deposit limits, so set the amount your contract and the law allow. After the deposit, each Buildplus invoice lists the costs behind it, tied to the budget and backed by attachments. That record helps show that each payment matches the work performed.
The takeaway
"Deposit" is an overloaded word, and construction uses its less intuitive meaning. A construction deposit gets spent on the project, and the owner gets its value back as credit against the price.
Confusion starts when that path is invisible. In Buildplus, the deposit has its own balance, carries the work between invoices, and comes back to the owner one visible credit at a time. The homeowner always knows how much credit remains. The contractor always knows how much of the project's cash is already spoken for.
