Free Construction Billing Template (Download and Guide)

A kitchen remodel and a commercial buildout bill differently, even when the same trades do the work. The contract type you signed determines the entire billing structure: what columns appear, how costs break down, and when payment is due. That is why Levelset offers five separate construction invoice templates rather than one generic form.

This page gives you a free construction billing template built for the way construction projects actually bill. Below it is a section-by-section guide explaining what each field does, how to adapt the template to your contract type, and where most billing disputes originate.

What goes on a construction billing template (section by section)

Construction invoices require fields that standard invoices skip. Your header needs your business name, address, phone, and email, but also your contractor license number, insurance status, the invoice number and date, the client's PO number (if issued), the job site address, the project name, and the contract date.

The PO number matters more than most contractors realize. Accounts payable departments will reject invoices that do not reference a PO before anyone reads the rest of the document. Larger companies and general contractors may run three or four jobs at once from different bank accounts, so including the job site name and address is critical to getting paid quickly.

Materials

Materials should be their own section, separate from labor. Each line needs four columns: description, quantity, unit cost, and line total. "Lumber" is not a line item. "2x6 pressure-treated lumber, 12 ft" is. Part numbers or product specs prevent disputes and give the client a way to verify pricing.

Some contractors mark up materials 10% to 20% to cover procurement time, delivery coordination, and storage. If you do this, show the markup as its own line ("Materials handling, 15%: $136.98") rather than baking it into each unit cost. Transparency here prevents the client from comparing your prices against retail and assuming you are overcharging.

Labor

Labor is where most invoice disputes start, because vague billing invites questions. Break labor into individual tasks or trades rather than lumping it into one line. A line reading "Labor: $4,800" gives the client nothing to verify. Four lines reading "Demolition (2 workers, 8 hrs each, $35/hr): $560" tell a different story.

Equipment and rentals

Rented equipment, owned equipment usage, and any specialty tools should each appear as separate line items with dates and rates.

Change orders

This is the section most generic templates miss entirely, and it is the one that causes the most payment friction on construction projects. Each approved change order should appear as its own line group on the invoice, referencing the signed change order number, the adjusted scope, and the dollar impact.

A change order must include six elements to be enforceable and billable: a clear description of changes, the parties involved, the updated total contract price with an itemized cost breakdown covering labor, material, and equipment, markup disclosure, a revised completion date, and a revised payment schedule. Before both parties sign it, a change order is a proposal, and proposals do not generate invoices.

For a deeper look at when change orders are required and how to structure them, see our construction change order guide.

Totals and payment terms

The bottom of your template should show the subtotal, any applicable sales and state tax, the total due, the payment due date, accepted payment methods, and your late fee language.

Which template format matches which contract type

Four construction contract types create four different billing structures. Using the wrong format creates confusion and delays payment.

Contract type	How it bills	Template focus
Fixed-price (lump sum)	Total price locked before work begins; contractor carries cost risk	Single total line or milestone percentages. Detailed materials and labor columns are less relevant because the contract focuses on overall amounts and percentages.
Time and materials (T&M)	Contractor bills actual materials and labor plus an agreed profit margin; risk shifts to the client	Full materials and labor breakdowns with quantities, rates, and hours. Documentation must be airtight.
Cost-plus	Client covers all direct expenses plus an agreed fee or percentage; contractor is protected on costs	Itemized expenses with receipts, plus a clearly labeled fee line. The client needs to see every dollar.
Unit price	Project broken into measurable units (cubic yards, hours) each with a fixed price	Quantity-driven columns. Each unit type gets its own line with quantity delivered and unit rate.

A template built for T&M work, with detailed hourly breakdowns, looks nothing like a lump sum template with a single contract total. Match the template to the contract before you send the first invoice.

Progress billing: when you need multiple invoices, not one

Short residential jobs can bill on completion. Anything longer needs progress billing, where you invoice at intervals throughout the project.

Progress billing has three structures: time-based (invoices at regular intervals like monthly or biweekly), milestone-based (invoices when the contractor reaches a major project phase), and percentage-based (invoices at set completion percentages such as 30%, 60%, 100%).

Each progress invoice must include the total contract amount, approved change orders and adjusted price, total billed to date, current completion percentage, and remaining balance.

The schedule of values

A schedule of values (SOV) is a line-by-line list of every work item with a dollar amount assigned to each component. Contractor and owner agree on the SOV at contract signing. Each pay application then references that SOV to show what percentage of each line item is complete and how much is being billed for that cycle.

Including a schedule of values promotes transparency and protects contractors by putting estimates in writing. If a client disputes a bill three months into the project, you point to the SOV both parties signed at the start.

Retainage on progress payments

Most progress billing arrangements include retainage, a 5% to 10% holdback from each progress payment that the client releases only after the project is complete. On a $60,000 contract with 10% retainage across four milestones, the contractor carries $6,000 in earned-but-unpaid revenue until final completion. Your billing template needs a retainage line on every progress invoice so both sides track the running holdback.

Deposits, retainage, and late fee language

Three payment terms belong on every construction billing template.

Deposits. Required deposits run from 10% on large multi-stage projects up to 50% on smaller jobs, with 25% to 33% reasonable on medium projects. Your first invoice should show the deposit collected and deduct it from the balance due.

Retainage. Beyond progress billing, retainage holds back around 10% of each payment until project end. Track it as a separate line so the client sees the cumulative holdback and you have a paper trail for the release invoice.

Late fees. Late payment penalties are enforceable when clearly stated in the signed contract. Most states allow 1% to 1.5% monthly interest on overdue invoices. The fee does more than collect extra money. It signals to clients that you take payment seriously, and most clients who see a clear late fee pay on time to avoid it. Yet only 11% of construction companies regularly charge interest or late fees. If your template does not include late fee language, you are giving clients permission to pay whenever they feel like it.

What happens when billing is vague

The average construction business collects payment 83 days after the work is done. Nearly three months of your cash sitting in someone else's account.

Poorly drafted or incomplete and unsubstantiated claims rank as the top cause of construction disputes. The average global construction dispute value reached $52.6 million in 2021, with resolution taking an average of 16.7 months in North America. You are not operating at that scale, but the pattern is the same at every level: vague billing creates disputes, disputes create delays, delays cost money.

One in four construction professionals names late payments as a major cause of project delays. Seventy-six percent of projects hit by late payments lose at least a week. Thirty-eight percent lose more than three weeks. When payments are late, 56% of contractors shift workers to other projects, 21% pause work until payment clears, and 6% lose workers entirely.

Most late payments result from confusing contract terms where payment dates or milestones are unclear. A billing template with specific due dates, clear milestone definitions, and unambiguous late fee language removes that confusion before it starts.

From billing template to getting paid

A billing template is a document. Getting paid is a process. The template captures what is owed. Payment reminders, follow-up sequences, and late fee enforcement are what close the gap between sending the invoice and receiving the money.

Improving the payment process can cut almost 14% off total construction costs. Almost half of construction businesses still offer customers 30 days or more to pay an invoice, and nearly three-quarters offer no early payment discount. The template sets the terms. Enforcement makes them stick.

Nudge automates the reminder side of this. Once you send the invoice, Nudge schedules SMS and email reminders on the timeline you set, so the follow-up happens whether you remember to send it or not. The billing template tells the client what they owe. The reminder sequence tells them again, and again, until they pay. For more on building a follow-up system around your billing, see our guides on contractor billing software and how to time invoice reminders.

If a client still does not pay, your options depend on the paper trail your billing created. Our contractor lien guide covers the mechanics of filing a lien, and our change order template helps you document scope changes before they become disputes.
