How to apply Profit First in a construction business
A practical guide to organizing construction cash flow so materials, payroll, and profit are funded before the next project expense arrives.
Quick answer
Construction cash flow is uneven by nature: projects run for months, payments arrive in stages, and vendors need paying before the next payment lands
Profit First doesn't remove that timing gap, it gives you a system for organizing the cash you already have so nothing gets spent before it has a purpose
The core system uses five accounts: Income, Profit, Owner's Pay, Tax, and Operating Expense
Large annual costs like insurance and bonding get funded gradually all year, instead of becoming emergencies when the bill arrives
Profit First manages cash flow across the whole business. It's not a replacement for job costing, which tells you whether each individual project is actually making money
Construction businesses manage cash differently than most other industries. Projects often run for weeks or months. Customers pay in stages instead of all at once. Suppliers, subcontractors, payroll, and equipment costs frequently need to be paid before the next payment arrives. Because of this, many construction businesses stay busy and still feel constant cash flow stress. Profit First doesn't eliminate that timing gap. It gives you a simple system for organizing your cash so every dollar has a purpose before it's spent.
Why does a construction business need a different cash flow mindset?
The realities of the industry make cash timing genuinely harder to manage than in most businesses:
Progress payments arrive in stages, not all at once
Materials often need to be purchased upfront
Subcontractors expect to be paid on their own schedule, not the client's
Slow seasons happen regardless of how strong the pipeline looks
Insurance and bonding costs arrive in large amounts once or twice a year
Change orders can put crews to work on a job before the paperwork and the payment for that extra scope catch up
These are exactly the situations where intentional cash management becomes valuable.
What is Profit First?
Traditional accounting runs on one formula: Sales minus Expenses equals Profit. Whatever survives after every bill is paid becomes profit, if anything does. Profit First flips that order: Sales minus Profit equals Expenses. Instead of hoping something is left over at the end, you intentionally reserve money first and run the business on what remains.
Shawn Van Dyke, author of Profit First for Contractors, built on Mike Michalowicz's original Profit First framework by introducing the concept of "real revenue," income after materials and subcontractor costs, as the base for allocation percentages in construction businesses. Van Dyke also coined the term "Craftsman Cycle" to describe contractors who stay busy on paper while never actually getting ahead financially. The five-account system and the core Sales minus Profit equation come from Michalowicz's original book; Van Dyke's contribution is adapting that structure specifically for how contractors get paid.
How does Profit First work in a construction business?
| Account | What it's for |
|---|---|
| Income | Every customer payment lands here first, nothing gets spent from it directly. |
| Profit | A protected share set aside as a reward for the risk of ownership. If this seems impossible right now, start with just 1%. |
| Owner's Pay | Consistent compensation for the person running the business. |
| Tax | Money reserved so tax season is never a scramble. |
| Operating Expenses | What's left over funds day-to-day costs not covered by the accounts below. |
| Materials / Supplies | Money set aside specifically for job materials and supplies, kept separate so project costs don't blur into general overhead. |
| Payroll | A dedicated account for the funds necessary to run your next payroll. |
| New Equipment | A reserve built gradually for equipment purchases and replacement, so a broken piece of equipment doesn't become an emergency withdrawal from somewhere else. |
What construction businesses need beyond the five core accounts
Profit First organizes cash flow so every dollar has a job. It does not tell you whether an individual project made money. That is the role of job costing, which tracks labor, materials, and overhead against budget for each project.
A construction business can hit every Profit First percentage target and still have a job quietly eating into the business underneath. The two systems work best together. Profit First manages cash across the whole business. Job costing tells you which projects are actually earning their keep.
Beyond the standard five accounts, three construction-specific concepts are worth understanding before setting up the system.
Retainage is the percentage of each progress payment, commonly 5 to 10 percent, that a client withholds until project completion or punch-list sign-off. Terms vary by contract and jurisdiction, and some contracts reduce the withheld percentage once the project crosses 50 percent completion.
For Profit First purposes, retainage is excluded from allocation calculations until it is actually released and deposited. It is not available cash. The same applies in reverse: retainage you are holding back from subcontractors is not available operating cash either, since you will owe it out once their work is complete.
Drip account is a practitioner adaptation used by Profit First Professionals for project-based businesses where a client pays a large upfront deposit but the work spans several more months. Rather than allocating the full deposit immediately as earned income, roughly one month's worth stays in the income account for standard allocation while the remainder moves to the drip account and is drawn down gradually as the project progresses.
This connects to what your CPA or bonding agent may track on your work-in-progress schedule.
Overbilling means you have billed more than the work completed to date. The cash is in the account but not fully earned yet.
Underbilling means you have completed more work than you have billed for. Cash is lagging behind the work in the ground.
A drip account is a practical way to manage the cash side of an overbilling situation so a large deposit is not spent before the matching work is done.
Vault account is a separate savings account, held at a different bank from operating accounts, used by many Profit First Professionals to set aside funds for large irregular expenses specific to construction: equipment failures, insurance renewals, bonding costs, and slow season shortfalls. It is funded with a small fixed percentage of every real revenue deposit. Keeping it at a separate institution creates enough friction to discourage using it for anything other than its intended purpose.
Step 1: Deposit every customer payment into your income account
Every payment from a customer lands in one place first. Don't pay bills directly from incoming deposits. This single habit creates visibility that most construction businesses don't have: a clear view of what's actually come in before any of it gets spent.
Step 2: Allocate money to its purpose
Once money arrives, divide it between Profit, Owner's Pay, Taxes, Operating Expenses, and the additional accounts above. The exact percentages depend on your business, but the goal is always the same: every dollar receives a job before it's spent.
Step 3: Plan ahead for annual expenses
Construction businesses often carry predictable but irregular costs:
General liability insurance
Workers' compensation
Equipment maintenance
Vehicle registration
Licenses
Bond renewals
Instead of scrambling when these bills arrive, gradually build cash reserves throughout the year, whether in your Vault account or a dedicated reserve. This prevents one large payment from disrupting everyday operations.
If your business bids bonded work, there's a second layer worth knowing about. Sureties set your bonding capacity largely based on working capital and equity on your balance sheet, and large owner distributions taken right before a reporting period can shrink that number. If growing your bonding capacity is a goal, it's worth talking with your CPA about how your Profit First distribution timing lines up with your bonding needs, so the two are working together rather than against each other.
Step 4: Pay vendors from your operating expense budget
Vendor payments are part of running the business. Profit First helps you see clearly whether your operating budget actually supports those costs before you spend the money. If your Operating Expenses account consistently feels tight, treat that as a signal to review pricing, project costs, or overhead, not a reason to borrow from taxes or profit.
Step 5: Review your cash flow regularly
Construction projects change as they go. Review your accounts every allocation day and ask:
Are we setting aside enough for taxes?
Are upcoming insurance payments covered?
Do we have enough operating cash for payroll?
Are project costs staying within budget?
Is our drip account funding the months of work still ahead?
Small adjustments throughout the year are easier than solving a cash shortage later.
A simple example
ABC Construction receives a $40,000 progress payment, half of it a deposit for a project that will run three more months. The company first sets aside a month's worth of that deposit in the income account and moves the rest into the drip account to fund the remaining work. From the portion allocated today, money is set aside for profit, taxes, owner's pay, materials, payroll, and operating expenses. When the annual insurance premium arrives three months later, the funds are already waiting in the Vault account, because the money was set aside gradually instead of treated as an emergency.
Common mistakes construction businesses make
Waiting until the end of the month to see if there's any profit left
Treating every dollar in the bank balance as available cash, including retainage that hasn't been released yet
Forgetting to save for annual insurance and licensing costs
Paying expenses before assigning every dollar a purpose
Starting change order work before the price and payment terms are locked in
What construction owners usually ask about this
Does Profit First work for construction businesses with long projects?
Yes. The system works with cash you've already received, which makes it well suited to businesses that get paid in stages throughout a project rather than all at once.
Does Profit First replace job costing?
No. Profit First manages cash flow across the whole business. Job costing tracks whether an individual project is profitable. You need both: Profit First keeps the business from running out of cash, and job costing tells you which jobs are worth bidding again.
How do I prepare for annual insurance premiums?
Set aside money regularly throughout the year, often through a Vault account, so large bills become planned expenses instead of financial surprises.
What if I need to pay subcontractors before my next customer payment arrives?
Planning your operating cash in advance helps reduce this pressure. Reviewing project budgets and maintaining cash reserves also helps manage the timing gap between customer payments and vendor invoices.
What's the difference between retainage and a drip account?
Retainage is money your client withholds from you until the project is complete; it's not yours yet, so it stays off your books until it's released. A drip account is money you set aside from your own deposit to fund work you haven't done yet. They solve different timing problems.
Does Profit First affect my bonding capacity?
It can, if you're not careful. Sureties look at working capital and equity on your balance sheet, and large owner distributions can reduce both right before a reporting date. If you bid bonded work, it's worth coordinating your Profit First allocations and distribution timing with your CPA so you're building profit and protecting your bonding capacity at the sam e time.
Should I change my allocation percentages every month?
Not usually. Start with percentages that fit your business, review them regularly, and adjust gradually as your business grows.
Can Profit First replace my accounting software?
No. Profit First is a cash management system. Your bookkeeping and accounting software remain essential for tracking your financial records.
Construction businesses often generate strong revenue while still struggling with cash flow, because money isn't organized around future obligations.
