A subcontractor invoice template is a reusable document for requesting payment for work completed under a contract. It should identify the subcontractor and client, describe the work and billing period, show the amount due, and state when and how payment is expected. Use the blank template below as a starting point, then adjust it to match the project agreement and the client’s submission requirements.
What a Subcontractor Invoice Does
A subcontractor invoice is a payment request from a business or individual hired to perform part of a larger project. For example, a general contractor might hire a painter, electrician, installer, or freelance drafter, and the subcontractor invoices for the agreed work. The invoice records what was provided and the amount being requested; it is not, by itself, proof that a client has approved the work or paid it.
Invoices also help both parties keep project records consistent. A clear document can connect a payment request to a particular job, work order, contract, or billing period. That is useful when a project has several subcontractors, repeated invoices, or multiple stages of work. The invoice should reflect the terms the parties already agreed to rather than introduce new charges or change the agreement after the fact.
There is no single universal layout that every client accepts. Some clients ask for a specific form, purchase order reference, or supporting documents. Before using a general template, check the contract and ask the client what information and submission method it requires.
How Subcontractor Invoicing Works
The usual process begins with an agreement that defines the scope of work, pricing method, milestones, and payment process. Once the subcontractor completes a billable portion of the work, they prepare an invoice that identifies the project and explains the charges. The client reviews it against the agreement and any required records, then processes an approved amount according to the agreed payment terms.
Billing frequency depends on the arrangement. A subcontractor may invoice after each milestone, at regular intervals, or when a defined task is complete. A one-time service might need only one invoice, while a longer project may involve progress invoices. Each invoice should make its coverage period or completed milestone easy to distinguish from earlier requests.
For example, a fictional flooring subcontractor could invoice for installation completed on the second floor during a stated two-week period. The description should identify that portion of the job, not simply say “labor.” If the subcontractor previously billed for the first floor, the new invoice should make clear that it covers different work and should not repeat the earlier charges.

Sample (fictional): Northline Finish Carpentry; invoice FC-104; dated October 3, 2026; billed to Cedar Street Renovation; project: 18 Cedar Street; work period: September 16–30, 2026. One line item: “Install interior trim, second-floor bedrooms,” 24 hours at $45 per hour, line amount $1,080. Fictional subtotal and total due: $1,080. This example shows formatting only; the names, dates, and figures are invented.
What to Include on Each Invoice
Start with identifying details. Use a unique invoice number and date, your name or business name, and the client’s correct billing name and address or other requested contact details. Add a project identifier, such as the site address, job name, contract number, or work order. These references help the client route the invoice to the right project and distinguish it from other requests.
Describe the work in terms that someone reviewing the agreement could recognize. Include a date range, milestone, location, or deliverable where it helps clarify the charge. If billing by time, show the hours and rate; if billing by unit, show the quantity and unit price; if billing a fixed milestone, name the milestone and agreed amount. Avoid vague entries such as “services” when a more precise description is available.
Show the arithmetic in a way that can be checked. List line amounts, subtotal, any agreed additions or credits, and the total due. State the payment terms or due date that apply under the arrangement, and provide payment instructions if the client needs them. If supporting records are required, mention or attach them as requested. Examples can include approved time records, a delivery record, or a milestone sign-off, but only include documents relevant to the job and permitted by the client’s process.
Calculating Charges and Explaining Changes
The invoice should follow the pricing method in the agreement. For hourly work, multiply billable hours by the agreed rate and show the calculation. For unit pricing, multiply the number of accepted units by the unit price. For a fixed-fee milestone, use the agreed milestone amount rather than presenting it as an hourly charge. These simple breakdowns make it easier to spot a data-entry error before the invoice is sent.
Keep approved extras distinct from the original scope. If the client authorized additional work, identify it separately and reference the approval or change instruction when appropriate. Do not silently add materials, travel, equipment, or other expenses if the agreement does not provide for them. Similarly, show a credit or prior payment clearly if it is being applied to the current amount, so the client can see how the total was reached.
As a fictional example, suppose a subcontractor’s agreed rate is $45 per hour and the invoice covers 24 billable hours. The labor line is 24 multiplied by $45, or $1,080. If a separately approved delivery charge is also being billed, list it as its own line and explain its basis; do not merge it into the labor description. Any applicable tax treatment depends on the transaction and relevant rules, so do not assume that every invoice should add the same tax amount.
Sending the Invoice and Tracking Its Status
Before sending, compare the invoice with the agreement, the work actually completed, and the client’s instructions. Confirm that the billing name, project reference, dates, quantities, rates, and total are correct. Check whether the client requires a particular file format, portal, email address, approval code, or attachment. Sending a correct invoice through the wrong channel can still delay review.
- Use a clear file name that includes the invoice number and project reference.
- Include only the supporting records the client requests or the agreement calls for.
- Keep a copy of the submitted invoice and note when and how it was sent.
- If the invoice is returned, record the reason and submit a corrected version that is clearly identified.
- Follow up politely if the expected review or payment date passes, referring to the invoice number and project.
When revising an invoice, avoid leaving two apparently current versions in circulation. Identify the replacement as corrected or revised and follow the client’s process for cancelling or superseding the earlier copy. Keep the original in your records so the history remains understandable.
Common Invoice Problems to Avoid
A frequent problem is a description that is too general to verify. “Construction work” does not tell a reviewer which task, period, or milestone is being billed. Another is a mismatch between the invoice and the contract: a different rate, unexpected expense, or billing date can prompt questions even when the work itself is complete. Use the agreed terms and explain any authorized variation.
Other avoidable issues include duplicate invoice numbers, missing project references, incorrect arithmetic, and billing for a period already included on an earlier invoice. A client may also hold an invoice that lacks a requested approval reference or supporting record. A short pre-submission review is often more useful than adding decorative design elements.
Do not treat an invoice as a substitute for required project approvals or records. If the agreement calls for a signed completion record or another authorization, the invoice alone may not satisfy that condition. Likewise, an invoice marked “paid” should reflect an actual payment, not simply a request or promise. Keep billing documents and payment records distinct and accurate.
Template Versus Client-Specific Billing Forms
A general template is useful when the client accepts ordinary invoices and you want a consistent layout for repeated work. It can make routine billing faster and reduce the chance of forgetting basic fields. A client-specific form or portal is preferable when the client requires structured fields, approval routing, or references that a general invoice does not capture.
These options are not necessarily competing approaches. You can use the template to gather accurate information, then transfer that information into the required client form. The important point is to meet the client’s submission requirements while keeping your own copy of the final invoice and related records. If a required field appears inconsistent with the agreement, ask the client to clarify rather than guessing.
Frequently Asked Questions
What should a subcontractor invoice include?
Include invoice number and date, subcontractor and client details, project reference, work period or milestone, clear descriptions, quantities or hours, rates, line totals, total due, and applicable payment terms. Add any references or attachments the client specifically requires.
Can I use a regular invoice template as a subcontractor?
Yes, if it captures the information needed for the job and the client accepts that format. Check the agreement and submission instructions first; some clients require a particular form, reference number, or supporting record.
How do I invoice for subcontractor work by the hour?
State the work period, describe the task, list the billable hours and agreed hourly rate, and show the multiplication as a line amount. Attach or provide time records if required, and make sure the hours match the approved work and billing terms.
Should a subcontractor invoice include tax?
Whether tax applies and how it should appear depends on the transaction and applicable requirements. Do not add or omit a tax amount based only on another contractor’s invoice; ask a qualified tax professional about a situation that needs tax-specific guidance.
When should a subcontractor send an invoice?
Send it at the point and frequency set out in the agreement, such as after a milestone or for a stated billing period. If the timing is unclear, confirm the client’s process before sending repeated or overlapping requests.
What should I do if an invoice is rejected or disputed?
Ask for the specific reason, compare the disputed item with the agreement and project records, and correct factual errors or provide requested documentation. If the disagreement involves contractual, tax, or other professional requirements, ask a qualified professional for situation-specific guidance.
